The technical processing of designing and producing the cast iron recuperator for hot blast cupola is available.
根据熔化原理，提供设计制造铸铁热风炉胆的工艺过程和利用导程刮板的造型方法。
The KQDL series cupola was trial produced aiming at the problems existing in the cupola, cold blast cupola, hot blast cupola, water cooling cupola.
前言：针对冲天炉，冷风炉、热风炉、水冷却炉存在的问题试制出了“KQDL系列冲天炉”。
Results show that the total oxygen content of iron melts is markedly increased with the increase of blast moisture of the cupola.
研究表明，铁水中全氧量随冲天炉送风湿度增加而明显增大。
The blast ring and charging hopper of a cupola was modified. As a result, the break down rate and maintenance cost was obviously decreased, and the melting process became more smooth.
对冲天炉风圈、加料漏斗的技术改进，使冲天炉的故障率明显降低，维修费也大大下降，很好地保证了熔炼工序的顺利进行。
The principle and characteristics of KQDL series cupola which supply blast using air cooling, strengthening preheating and single row cyclone were discussed.
论述了“KQDL系列冲天炉”采用空气冷却、强化预热、单排龙卷风供风原理和特点。
