铸造生产对冲天炉的要求是;高温、优质、低耗。因此,在保证提供高温优质铁水的前提下尽量节约焦炭,是冲天炉熔炼操作所必须遵循的原则。我厂的1、5吨/时冲天炉,曾几经改造,用小风口取代大风口,由直筒式改为曲线炉膛,取得了一些经验教训。下面,根据生产实践的结果,谈一下对冲天炉改炉节焦的几点认识。 Casting production requirements of the cupola is; high temperature, high quality, low consumption. Therefore, in ensuring the premise of providing high-temperature high-quality hot metal as much as possible to save coke, cupola smelting operation must follow the principle. I 1,5 tons / hour Cupola, has been transformed, with a small tuyere to replace the gale, from straight to the curve furnace, made some lessons. Below, according to the results of the production practice, talk about the cupola converter focus of the festival to understand.
