英国S.Russell ＆ Sons公司的铸造部门,已经把能源管理上升为优先考虑的项目。主要能源价格的上涨,已影响到制芯方法、熔化原材料和工艺、以及冶炼操作的改变。该公司从1952年起生产片墨铁和球墨铁,由于环境污染,从72年起,以两台1.5吨工频炉取代冲天炉。该厂备有高、中压造型,CO_2水玻璃法制芯,铸件重量30～300kg,产品为齿轮箱、床身等。图1所示为12个月内化铁所用的能耗率。图中(1)为铁水能耗,(2)为未计废品的铸件能耗,(3)为
The casting division of S. Russell & Sons in the United Kingdom has raised energy management as a priority. The rise in major energy prices has affected the core making process, the melting of raw materials and processes, and the changes in smelting operations. Since 1952, the company has produced ductile iron and ductile iron. Since 1972, the company has replaced the cupola with two 1.5-ton industrial furnaces due to environmental pollution. The plant is equipped with high and medium pressure shape, CO_2 water glass legal core, casting weight 30 ~ 300kg, the product is gear box, bed and so on. Figure 1 shows the energy consumption rate of iron for 12 months. (1) is the energy consumption of hot metal, (2) is the energy consumption of the castings without waste, (3) is
