自从1974年在天津召开技术鉴定会以来,无水冷滑轨加热炉新技术在这三年中有了不少新的进展。无水冷滑轨使用寿命由半年提高到一年或一年以上。中型无水冷滑轨加热炉的试点工作正在开展之中。目前,各地采用无水冷滑轨的加热炉已有十几座。无水冷滑轨加热炉突出的节约燃油的效果,超过了其他各种节约措施。天津轧钢二厂和上钢八厂的无水冷滑轨加热炉加热每吨钢的耗油量最低都曾降到40公斤以下,一般也在50公
Since the technical appraisal meeting was held in Tianjin in 1974, the new cold-slide rail heating furnace technology has made new progress in the past three years. The service life of water-free cooling slides increased from six months to one year or more. Pilot work for medium-sized anhydrous slide rail heating furnaces is underway. At present, there are more than a dozen heating furnaces that use anhydrous cooling slides. The outstanding fuel-saving effect of the anhydrous cold-roller slide heating furnace surpasses all other economical measures. The cold-rolled slide rail heating furnaces of Tianjin No. 2 Iron & Steel Plant and No. 8 Steel Plant have the lowest fuel consumption per ton of steel and have fallen below 40 kg.
