水平或倾斜往复式燃煤炉排机以其机械化程度高、环境污染少等优点得到很多工厂的采用。我厂从1982年开始在轧钢加热炉中使用这种炉排机。但原来使用的S型铝硅耐热合金铸铁炉排使用寿命短,在加热炉高温区使用寿命仅10～15天,有的只有一星期,每年的炉排消耗量为炉排机装机重量的8倍,而且每年因更换炉排而造成停产的时间达400h左右,严重影响了轧钢生产。同时,操
Horizontal or inclined reciprocating coal-fired furnace row machine with its high degree of mechanization, environmental pollution and other advantages of the use of many factories. I plant from 1982 in the rolling furnace in the use of this grate machine. However, the original use of S-type aluminum-silicon heat-resistant alloy cast iron grate life is short, in the furnace high temperature service life of only 10 to 15 days, and some only a week, the annual grate consumption for the grate machine weight 8 times, but also due to replace the grate and stop production due to the time of 400h, seriously affected the rolling production. At the same time, fuck
