东风汽车公司铸造三厂,采用CA-86型浇注料浇注成形20t无芯工频电炉炉盖内衬,收到满意的效果。 CA-86型浇注料,是采用铝矾土耐火材料配以CA-86型高温耐火胶泥混制面成的不定形耐火材料。制成的炉盖使用寿命较长、耐高温性能好、炉盖重量轻,成本低。由于CA-86耐火胶属于磷酸盐性质,故在使用时必须注意以下几方面问题: a.在混制过程中,严禁材料与水接触。因材料中加入水后将显著降低混料的强度,影响其使用性能。 b.耐火胶泥入量不宜过多,过多的加入
Dongfeng Motor Corporation casting three plants, the use of CA-86 castable cast 20t coreless frequency furnace lid lining, received satisfactory results. CA-86 castable, is the use of bauxite refractory material with CA-86 high temperature refractory clay mixing surface of amorphous refractory material. The cover made of longer service life, high temperature performance, light weight, low cost. CA-86 fire-resistant plastic due to the nature of the phosphate, it is necessary to pay attention to the following aspects in the use of the problem: a. Mixing process, the material is prohibited contact with water. Due to the material after adding water will significantly reduce the strength of the mixture, affecting its performance. b. The amount of refractory clay should not be too much, too much to join
