1958年底下塔吉尔冶金联合企业第一平炉车间顺利地进行了大型平炉新炉底的快速烧结。所用烧结料为:“超级”镁砂,冶炼沸腾钢的平炉渣(粉碎)及干燥的轧钢屑;其化学成分及颗粒组成见表1。快速烧结的特点是时间短,因为用这种方法烧结炉底时,只须烧结四层,而以前则要烧结十四层。即先用前三层造成与砖砌体牢固烧结在一起的炉底基体,再用复盖轧钢屑的厚镁砂层(第四层)得到致密的耐火外壳。最后一层在头几炉中形成。在观测到炉底温度经过8小时仍保持不变以后,即可进行炉
By the end of 1958, the first open hearth furnace workshop at Tajesche Metallurgical Complex successfully carried out the rapid sintering of a large open hearth new hearth. Sintered material used for: “super” magnesia, smelting boiling slag flat steel (crushed) and dry rolling scrap; the chemical composition and particle composition in Table 1. Fast sintering is characterized by a short time, because sintering furnace bottom with this method, you only have to sinter the four, compared with 14 before sintering. That is to say, the first three layers are used to make the furnace bottom matrix which is firmly sintered with the brickwork, and then the dense refractory shell is obtained by the thick magnesia layer covering the steel scrap (the fourth layer). The last layer formed in the first few furnaces. After observing the bottom temperature remains unchanged after 8 hours, you can carry out the furnace
