烏拉尔車廂厂的煉鋼車間里有一只电爐,过去最多熔煉50次就要修理,而当使用了一种新的爐襯后它已經熔煉了一万二干爐钢,也就是五年以来还沒有修理过。有一次,車間的工長斯齐班同志注意到修补爐襯的一种材料比磚襯耐用,这些材料是用石英粉、粘土和水玻璃混合制成的,貼补上去后經过高溫燒结便牢貼在磚襯上。斯齐班和他的同志們由于这方法的啓發,經过無数次的試驗(硅磚粉、石英砂、耐火粘土、鎂砂、鉻矿石、水玻璃等等),克服了許多困难,終于在車間党組織的支持和帮助下找出了一种最好的补爐材料,它的成份是92％廢鎂磚或廢銘鎂磚粉和8％耐火粘土。虽然耐火材料找到了,可是如何把这些稠稠的泥料貼到垂直的爐壁上去呢?經过研究,他們很快
There is an electric furnace in the steelmaking plant at the Ural car factory, which was repaired in the past by melting up to 50 times and after it had been used with a new lining, it had melted up to 12,000 kilns, Not repaired. On one occasion, Comrade Skibin, the shop’s chief engineer, noticed that one of the materials used to repair the lining was more durable than brick linings. These materials were made from a mixture of quartz powder, clay and water glass, Stick firmly on the brick lining. Inspired by this method, Skiband and his comrades have overcome numerous difficulties through innumerable trials (silica bricks, quartz sand, refractory clay, magnesia, chromite, water glass, etc.) With the support and help of the workshop party organization, one of the best ingredients for refilling was found, which consisted of 92% of waste magnesia brick or 8% of refractory clay. Although refractory materials are found, how can these thick paste materials be applied to a vertical furnace wall? After research, they quickly
