摘　　要：用矿热电炉处理煤矸石,并对制取矿物无机纤维的工艺技术条件进行了研究,发现通过加入辅助添加剂,用煤矸石可制取无机纤维.试验结果表明:在石灰添加量为20%、铁精粉添加量为25%,以及石灰石添加量为20%、镍红土矿添加量为100%的条件下,电炉冶炼均能正常进行且能制备出无机纤维,所制备的无机纤维经处理后可获得合格的纤维保温板.The technique of producing mineral inorganic fiber using smelting electric furnace to process coal gangue is investigated.It is found that coal gangue can be made into inorganic fibers by adding auxiliary additives.The results show that electric furnace smelting are in normal work and can prepare inorganic fiber with the condition of adding 20%lime and 25%iron ore,or 20%lime and 100% nickel laterite ore.The qualified fiber insulation board can be made after treating the inorganic fiber.
