“煤粉化铁炉”“重油化铁炉”是铸造生产战线中的一项技术革新,但由于它们都普遍存在着炉衬浸蚀严重,炉龄寿命短等缺点,大大地影响其进一步推广和应用。我们曾对“煤粉化铁炉”采用不同耐火材料进行多次试验,效果都不显著。后来,试采用“热风水冷炉衬煤粉化铁炉”。经过一年多的生产实践证明,“水冷炉衬”基本上能解决当前普遍存在炉衬寿命短的问题。 “Coal iron boilers” and “heavy oil boilers” are a technological innovation in the casting production front. However, due to their widespread erosion of furnace linings and short service life of furnaces, they greatly affect their further promotion and application. We have carried out many tests on “pulverized coal furnace” using different refractory materials, the results are not significant. Later, try using “hot air water-cooled lining coal-fired iron furnace.” After more than a year of production practice has proved that “water-cooled lining,” basically to solve the current prevalence of short lining life problems.
