河南省陕县农业机械厂连续铸管的铁水由搀炉供给,每小时约需1吨。搀炉的炉衬原用耐火砖修砌,但只能熔化40多小时,这种经常要停炉、修炉的情况适应不了该厂连续铸管三班生产的需要,于是试验用本省禹县花石公社山张大队的天然红硅石修砌搀炉炉衬,取得较满意的效果。搀炉的结构如下图,炉身4部分砌了四层红硅石2;在炉顶3部分,我们砌了三层红硅 Henan Shanxian Agricultural Machinery Factory Continuous casting of molten iron by the furnace feed, about 1 ton per hour. Furnace lining furnace with refractory brick repair, but can only be melted more than 40 hours, this often to stop furnace repair furnace can not adapt to the situation of the plant three consecutive cast pipe production needs, so the test with the Yu County, the stone Commune Hill Zhang brigade natural red silica repair mix furnace lining, to obtain more satisfactory results. Mixing furnace structure as shown below, 4 parts of the furnace body built four layers of red silica 2; 3 in the roof, we built three layers of red silicon
