Metallurgical lime – Hydraulic Couplings Manufacturer – China Turned parts
In recent years, China’s metallurgical industry, although the overall lime has made significant progress, but now the whole industry at the equipment level, product quality, the use of consumption of raw materials guarantees, etc. with the world’s industrialized countries there are still a big gap. Self-development from the industry point of view, the future should focus on solving three problems:
First, the technological transformation of iron and steel enterprises must simultaneously supporting the building of active lime production facilities. First, we must ensure the realization of steel-making production fully implemented active lime, which is steel-making processes to ensure energy-saving emission reduction, improve product quality and reduce lime consumption and thus reduce the cost of steel integrated important measures. Compared with ordinary lime lime activity, effective CaO high porosity big, strong characteristics of a chemical reaction. Secondly, for sintering for production of lime, within a specified time-out and simple kiln kiln equipment, gradually raise the level of equipment, and ultimately used in all the production activity of lime.
Second, iron and steel enterprises should immediately take the limestone resources in long-term protection measures and carry out back-up strategic reserves of limestone mines work. Currently, there are few detailed exploration of the mine, high-quality limestone resources are declining will be a prominent issue, attention should be paid.
First of all, strengthen the back-up exploration work. The current consumption of limestone by national projections, if no new reserves are maintained, the existing limestone and the amount of resources will be 15 to 20 years have all been mined light. The geological exploration work in the 20th century, since the late 80s in a market-oriented operation, compensation for the use. With higher levels of limestone resource shortages, demand for large enterprises should take the lead in the implementation of enterprise resource investment strategy of measures to ensure future stable supply of accessories and mineral resources. Small businesses may take stake in cooperation, joint investment.
Second, the limestone mine construction to achieve the scale, resource-rich areas in the limestone to build large limestone raw material supply base in order to achieve intensive production. Iron and steel industry should accelerate the pace of the construction of metallurgical flux base, medium-sized iron and steel enterprises should be controlled auxiliary mine. In fact, in recent years, many domestic steel companies have begun to participate in competition for resources in high-quality limestone.
Third, strengthening the metallurgical lime production and application of technical and economic studies. The current professional research force is obviously inadequate, with regard to application of lime production and the subject of many technical and economic aspects of a lack of theoretical basis for further study and systematic practice of verification. For example, with independent intellectual property rights-based study of energy-efficient lime kiln, steel mills of surplus low heat value gas fuel technology research calcined lime, lime water-based product to maintain active technical studies, lime-kiln waste heat utilization, lime quality and steel, sinter production the relationship between the economic benefits of research. Theoretical research and practical verification of breakthrough that could encourage enterprises to realize all-round modernization will help the steel industry to speed up the pace of change from large to strong.
