卡腰化铁炉在湖北地区经过十多年的实践、研究和发展,已在1～5吨化铁炉上推广采用,在利用一般地方焦的情况下,获得了温度高、烧损少、氧化低的优质铁水,生产了各种牌号的灰铸铁、球墨铸铁和可锻铸铁,降低了铸件废品,改善了铸件质量,且可利用原有炉型改装,投资不大,效果显著。一、熔化效果卡腰化铁炉有多种型式,以两排短间距大斜风口效果最好。这种型式的1吨/时卡腰化铁炉1979年1月工艺试验鉴定指标为; 1.铁水温度:平均1500℃,波动范围为1470～1535℃(出铁槽测定);
Card waist iron furnace in Hubei after more than 10 years of practice, research and development, has been in the 1 ~ 5 tons of iron stove to promote the use of the general situation in the coke, access to high temperature, less burning, Low-quality high-quality molten iron, the production of a variety of grades of gray iron, ductile iron and malleable iron, reducing the casting waste, improve the quality of castings, and can use the original furnace modification, little investment, the effect is significant. First, the melting effect Card waist iron furnace has a variety of types, with two rows of short-pitch large oblique outlet the best. This type of 1 ton / hour card waist iron furnace in January 1979 identified the technical test indicators; 1. Hot metal temperature: an average of 1500 ℃, the fluctuation range of 1470 ~ 1535 ℃ (iron tank determination);
