From the large-scale production, large consumption, big waste to the input reduction, energy consumption, recycling technology, waste resource

September 12, 1700 Benxi Iron and Steel hot rolling mill production line factory started the repair. The investment of 40 million yuan will be modified making “1700″ level of automation in production lines, hydraulic levels and controlled rolling and accuracy and so on to achieve world-class standards, which will increase annual comprehensive finished product rate from 0.1 to 0.2 percent annual increase in output value 20 million yuan.

centuries Benxi Iron and Steel is quietly have changed: Through technological transformation, technological innovation, strengthen management, recycling ideas, recycling and other means of implementation, Benxi Iron and Steel In addition to product structure, upgraded to mention, the noise down, and smoke reduction in , and that pungent smell of the smell also. In the final analysis a word, the old iron and steel companies are trying to transform the economic growth mode from the original “big three”, that is, large-scale production, large consumption, big waste, into a “three-type”, that is, reduction of inputs, energy consumption recycling of waste resource.

from the Source input minimization

— input reduction, is from the roots with minimal input for maximum output. In the final analysis, is a “province” the word, water, energy-saving, Sheng Mei, saving all the means of production and costs. In this regard, the Benxi Iron and first of all start from the transformation to spend 500 million yuan reform on the 5th blast and spent 1 billion yuan, huh slab continuous casting, it took 20 million in transforming “1700″ rolling production line, launched an annual output of 1.9 million tons of automobile steel sheet and high-end home appliance products such as two cold-rolled sheet project, with the contemporary advanced steel-making process technology on the 4th of converter steel production technology projects … … in changing the product mix at the same time, advanced production technology also greatly reduces the Steel production costs; followed rigorously enforce the full savings. Long light off and closed a long flowing water, office paper are fixed, timing to call the number of small and focused, everyone careful planning. Only the first half of the savings wiping machine woven on the value of 100 million yuan. Developed a strict conservation rules and regulations, investment and material standard, the operation there are provisions to eliminate lost by leaking Everything is done by interlocking tricks of acting, provincial and a little bit is a little bit; once again rely on scientific and technological innovation to save. Deputy Chief Engineer Tan Mingxiang steel mill, has developed a “Steel hot metal pretreatment process engineering,” and many other new technologies, business savings more than 4,000 yuan accumulatively. The first half of the entire company to achieve major scientific and technological innovation 12 to save money a billion dollars. Benxi Iron and Steel to reduce the cost of tons of steel, just like squeezing water from a sponge inside, like squeezing a row for 10 years. This year, the Benxi Iron and comprehensive energy consumption per ton steel has fallen to 0.79 tons of standard coal, down 0.047 tons of standard coal; converter steel material consumption down to 1091 kilograms, down 17 kilograms. Benxi Iron and Steel

input reduction, in the water appear even more prominent. In 2003, the Benxi Iron and built a sewage treatment plant, an annual 35 million cubic meters of water available to return to; large power plants built in the water and waste water pool, there are 1500 cubic meters per hour, re-use of water to return. At present, the Benxi Iron and Steel in a new water consumption per tonne of steel has dropped from 30 tons to 6.17 tons, industrial water recycling rates up to 94%.

energy consumption in the production cycle of the improved —

Benxi Benxi Iron and Steel is the first energy-hungry. Have either gone, Benxi Iron and Steel only know that they are energy-hungry, but also lose sight of their large capacity of this basic fact, “15″ period, the Benxi Iron and Steel has set the concept of circular economy began to tap its energy potential.

in the power-saving, the Benxi Iron and Steel blast furnace for three large-scale construction of the TRT supporting facilities, the original group at the reducing valve noise and temperature rise on the waste of energy consumption, through the expansion turbine plant to be recycling, not only reduces the blast furnace regional environmental noise, and the recovery of iron produced the equivalent of 30% of electricity consumption. At the same time, the company also built two blast furnace gas fired boilers, coal-fired boiler will be converted into two-ene-ene-blast furnace gas boiler, only the four boiler per hour, can “eat” 450,000 cubic meters of blast furnace gas a year Save more than 40 million tons of standard coal, and can achieve the goal of blast furnace gas and hold powder. In addition, the use of blast furnace gas pressure and heat built new power generation projects, generating 100 million kwh year can be realized and opened up new ways of saving energy.

Benxi see hot on the finish in mid-August production of coke oven coke dry quenching equipment, not only greatly improved the quality and output rate of coke, but also due to recycling of the red-hot coke, 80% of the heat, so that the furnace coke rate decreased by 2.5%, blast furnace production capacity increase by 1% a year can save 27.5 thousand tons of standard coal. Benxi Iron and Steel, the fifth largest blast furnaces, on the hot stove, the heat so that the gas into the furnace, the air temperature reaches 175 ℃, which reduces iron time, while also lowering the cost of iron.

the “throw three,” which saved to — Waste Resource

Benxi Iron and Steel has the “three throwing” in the past out of the name. First, throw calcium carbide residue. Because the ore production needs stripping, often removed the stone a few cars in order to obtain a vehicle mine. Therefore, the fields on the valley, the river next to the post-mining emissions everywhere carbide slag; two throwing tailings. This is the dressing the remaining waste, each block has an iron mine tailings dam, but also fly ash produced by power plants; third, throwing the production process slag, iron slag, dust and mud and so on. “Three throw,” not only damaged the environment, but also resulted in waste of resources.

Today’s Benxi Iron and Steel is implementing a “where to pick up where the throw away” line, to the past, when the waste thrown away or misplaced resources, obtain other to come back and re-play a role. Waitoushan an annual output of iron ore has been completed a block of 200,000 cubic meters of rock processing plants, the raw material is rock bits and products are mainly used in highway embankment construction, the market prospects; Limestone Mine also use carbide slag as a raw material, built a stone and powder production line, products are widely used in roads and housing. In the comprehensive utilization of the tailings powder, in addition to the retention of some high iron content, the value of further mining tailings powder, the mine built a Waitoushan produce 100,000 cubic meters of load-bearing brick factory; generation Plant use of fly ash, is building an annual output of 300,000 cubic meters of building blocks production line, these projects are to digest the waste tailings powder re-use project. In the steel slag, iron slag recovery, the Benxi Iron and water will build a steel slag slag processing production line, slag on the water will carry out magnetic separation, recycling all the ferrous materials; the water will be used as sintering slag flux in each of the ingredients in the application of sintering Corrigan Slag 300,000 tons; built an annual output of 500,000 tons of artificial mineral aggregate production line, all Benxi Iron scrap (high-ash, steel slag magnetic powder) mix evenly into a man-made mineral aggregate, for sintering ingredients; the use of of water will produce slag bricks and blocks used in construction, promotion of converter slag particles in the coolant to do, promote the use of steel slag backfill in engineering, road construction application, and strive to make a comprehensive utilization rate of 100% steel slag to achieve recycling.

从大规模的生产,消耗大,浪费大的投入减少,能源消耗,回收利用技术,废物资源

1700年9月12日本钢热连轧机生产线,工厂开始修复。的4000.00万元的投资将被修改使“1700”的生产线,液压水平和控轧和准确性等,以达到世界级水平,这将增加百分之0.1至0.2年综合成品率等自动化水平每年增加产值2000.00万元。

百年本钢正在悄悄地发生了变化:通过技术改造,技术创新,强化管理,回收的思想,再循环和实施,本溪钢铁除了产品结构,升级提,降低噪音等手段,和烟雾减少,而且气味刺鼻的气味也。在最后一个字的分析,老钢铁公司正试图改变从原来的“三大”的经济增长方式,即大规模生产,大量消费,极大的浪费,成为“三型” ,即减少投入,能源资源消耗的废物回收。
从源输入最小

—投入减少,
是从最小的最大输出输入的根源。在最后的分析,是“省”字,水,节能,盛美,节省一切生产和成本的手段。在这方面,本钢以及所有的改造首先启动花五号高炉五零零零零零零零零元改革,花了10亿元,嗯板坯连铸,它发生在改造“1700”连轧生产线2000万美元,推出190万的汽车钢板和高端家电产品,年产如二冷轧薄板项目,与当代先进炼钢工艺技术对转炉炼钢生产技术项目的第四… …在改变的同时,先进的生产技术还大大降低了生产成本,钢铁产品结构;遵循严格执行完整的储蓄。龙光起飞和关闭了长期流水,办公用纸都是固定的,时间要求小,重点突出,大家仔细的规划数量。只有在消灭了1亿元人民币的价值梭织机储蓄上半年。制定了严密的保护规则和规章,投资和材料标准,操作有消除一切渗漏损失的规定是由相互关联的表演,省,有点,有点伎俩,再次依靠科技创新保存。副总工程师谈祥钢铁厂,开发了一个“钢铁铁水预处理过程工程”和其他许多新技术,商业储蓄4000元以上,累计。整个公司上半年实现重大科技创新,以节省资金12亿美元。本钢降低吨钢成本,像挤海绵内部的水,像挤了10年一一行。今年,本钢吨钢下降到0.79吨标准煤,综合能耗下降了0.047吨标准煤;换算钢材消费量下降到1091公斤,下跌17公斤。本溪钢铁

投入减少,在水,更显突出。 2003年,本钢,建成了污水处理厂,每年3500万的水可回立方米;大型发电厂的水和废水池建工厂,有1500立方米每小时,重新使用水返回。目前,本溪钢铁在每吨钢新水消耗下降,从30吨至61吨,工业用水循环率高达94%。

能源在提高生产周期消费—

本溪本钢是第一个能源短缺。已往,本溪钢铁只知道他们是能源需求,而且还失去了他们的这一基本事实,大容量看,“十五”期间,本溪钢铁确立了循环经济的概念开始挖掘它的能源潜力。
在权力
节能,本溪钢铁高炉三个大型的泰爱泰党配套设施的规模建设,在减压阀噪音和温度对浪费能源消耗上升的原集团通过扩展汽轮机厂,被回收,不仅降低了高炉区域环境噪声和恢复生产的铁,30%的用电量相当于。同时,公司还建成了两座高炉煤气锅炉,燃煤锅炉将分为两个改建烯烯高炉煤气锅炉,每小时只有4个锅炉,可“吃”45万立方米高炉煤气,每年节省4000多万吨标准煤,可实现高炉煤气的目标,并保持粉末。此外,高炉煤气压力和建造新的发电项目,利用热能,产生一点○○○亿千瓦时年得以实现了节省能源的新途径开幕。

本溪见热就在8月中旬完成焦炭生产焦炉干熄焦设备,不仅大大提高了质量和产量,焦炭率,而且还由于红火的焦炭,80%的热量回收,使高炉焦比下降了2.5%,高炉产量每年1%的运力增长可以节省27500吨标准煤。本溪钢铁,第五大高炉,热风炉上的热量,使入炉煤气,空气温度达到175℃,可降低铁的时间,同时降低钢铁成本。

“抛三”的保存—废弃物资源

本钢有“三个出扔过去的名字”。首先,投电石渣。由于矿石生产需要剥离,被拆掉的石头了几部赛车,以取得车辆地雷。因此,在河谷的田地,河流旁边的采矿后到处排放电石渣;两个投掷尾矿。这是穿衣服,剩余的废料,每座有一铁矿尾矿坝,而且飞行的发电厂所产生的灰烬;第三,扔在生产过程中渣,铁渣,灰尘和泥土等。 “三投”,不仅破坏了环境,而且造成资源的浪费。

今天的本溪钢铁正在实施一项“而拿起其中扔掉”行,过去,当垃圾扔掉或放错地方的资源,获得其他回来,重新发挥作用。歪头山铁矿的年产量已完成20万岩石加工厂立方米块,原料的石渣,产品主要用于公路路基建设,市场前景;石灰石矿也以此作为原料电石渣材料,建立了一个石头粉生产线,产品广泛用于道路和房屋。在尾矿综合利用粉,除了一些高铁内容的保留,进一步尾矿粉的价值,歪头山矿建成年产10万承重砖工厂立方米,发电粉煤灰利用粉煤灰厂,正在建设一个30万建筑砌块生产线,年产立方米,这些项目是消化废物的尾矿粉再利用项目。在钢渣,铁渣复苏,本钢和水将建成钢渣矿渣加工生产线,对水渣将进行磁选,回收所有的有色金属材料,水将作为渣烧结焊剂在使用每一个在烧结水冲渣三十○点〇 〇 〇万吨申请的成分,建立了50万人造矿料生产线,年产,所有本溪钢铁废料(高灰,钢渣磁粉)调匀成人造矿物聚合,用于烧结配料,对水的使用会产生矿渣砖,建筑用块,推广转炉钢渣的冷却剂颗粒做,促进钢铁渣利用工程,道路施工中的应用回填,力争使100%的钢铁渣综合利用率,实现循环利用。06.9.21
