荷兰霍戈文公司艾莫伊登厂七号高炉,是一座炉缸直径13米的大型高炉.该炉配有四座自己设计的新型高温内燃式热风炉.于1972年11月投入生产,到1979年9月完成了高炉一代炉役的生产,总计生产铁水1280万吨.热风炉一代使用的平均风温在1150℃以上,其中1975年至1977年间隔风温水平较高,约在1250℃左右,最高的接近1300℃.拱顶一代平均温度近1400℃,最高的曾达1480℃左右.后因炉壳出现应力腐蚀现象,才采取降低拱顶温度操作,并以临时措施喷涂保护层,涂层料是用煤焦油环氧树脂,基本可满足生产要求.
Hoyoven, Netherlands The Alto Eden plant, the No. 7 blast furnace, is a large blast furnace with a 13-meter diameter hearth, equipped with four new high-temperature internal combustion hot-blast stoves of its own, put into production in November 1972 to 1979 In September of this year, it completed the production of a blast furnace, a total of 12.8 million tons of hot metal, and the average temperature of the hot blast stove was above 1150 ℃, of which the air temperature was relatively high at about 1250 ℃ from 1975 to 1977 , The highest close to 1300 ° C. The average temperature of the vault generation of nearly 1400 ° C, the highest has reached about 1480 ° C. After the furnace shell stress corrosion phenomenon, only to take to reduce the vault temperature operation, and temporary protective layer of spray coating Layer material is the use of coal tar epoxy resin, to meet the basic production requirements.
