冲天炉问题是当前突出而普遍的问题。国内冲天炉状况多属两类 :高耗无利而苦苦挣扎 ;低效微利而发展艰难。铸件内在质量的优化和降耗增益 ,有赖于冲天炉运转技术和管理水平的提高 ;随着环保和能耗政策的实施 ,冲天炉将面临越来越严峻的挑战 ,种种实际问题亟待解决。铸件表面质? Cupola problem is the current prominent and common problem. Domestic cupola conditions are mostly two types: high consumption and unfavorable but struggling; inefficient and difficult to develop. The optimization of internal quality of castings and the gain in reducing consumption depend on the operation of cupola and the improvement of management level. With the implementation of environmental protection and energy consumption policies, cupola will face more and more severe challenges and all kinds of practical problems should be solved urgently. Casting surface texture?
