TRIZ理论在原料场改造工程中的应用

APPLICATION OF TRIZ THEORY IN RAW MATERIAL FIELD TRANSFORMATION ENGINEERING

由于近年河钢集团邯钢公司产能快速增长,原料储运环节粉尘污染严重,原有第一原料场不仅储备能力已不能充分满足烧结和高炉工序对原燃料的需求,也无法满足环保要求。通过运用TRIZ理论,分析了第一原料场在贮存、供料能力方面存在的不足和料场原燃料自然损耗及环境污染问题,并转换为TRIZ标准问题,利用TRIZ理论的第5、7、17等发明原理对应现有问题进行改进,对原料场进行增容改造和环保封闭治理。改造后第一原料场采用大跨度网壳封闭技术,实现了100%环保封闭,同时占地面积减小了20%,最大储料量由40万t提高到80万t,储料量提高了100%,达到了预期目标。邯钢第一原料场改造工程为TRIZ理论的具体应用提供了案例参考。

Due to the rapid growth of production capacity of HBIS Hansteel Company in recent years,the dust pollution in the raw material storage and transportation links is serious,and the original first raw material yard cannot fully meet the demand for raw fuel in the sintering and blast furnace process,but also cannot meet the environmental protection requirements.By using TRIZ theory,the deficiencies in storage and feeding capacity of the first raw material yard and the natural loss of raw fuel and environmental pollution in the material yard were analyzed,and converted into TRIZ standard problems,and the invention principles of TRIZ theory such as 5,7 and 17 were used to improve the existing problems,and the raw material yard was transformed and environmentally closed.After the transformation,the first raw material yard adopts the large-span grid shell sealing technology,which realizes 100%environmental protection and closure,while reducing the floor area by 20%,the maximum storage capacity is increased from 400,000 tons to 800,000 tons,and the storage capacity is increased by 100%,which has reached the expected goal.The renovation project of Handan Iron and Steel First Raw Material Field provides a case reference for the specific application of TRIZ theory.
