湘钢炼钢厂用河南巩县生产的刚玉质耐火材料捣打出钢槽,使用证明,它具有粘钢少、粘渣少、耐冲刷、热稳定性好、寿命长(达50炉次)、节省耐火材料和非生产时间及减轻劳动强度等优点,适用于平炉、电炉出钢用。这种捣打料的骨料是刚玉和SiC,A1_2O_3含量高达60％,含5％碳粉,以一种特殊粘结剂结合,具有较好的综合性能,是一种较理想的出钢槽用耐火材料。
Iron and steel production plant in Xiangtan Iron and Steel Co., Ltd. Henan Gongxian production of corundum refractories ramming out the groove, the use of proof, it has less sticky steel, less sticky slag, erosion resistance, good thermal stability, long life expectancy (up to 50 heats) Saving refractory materials and non-production time and reduce labor intensity, etc., suitable for open hearth, electric furnace tapping. The ram material aggregate is corundum and SiC, A1_2O_3 content of up to 60%, containing 5% carbon powder, with a special binder combination, has good overall performance, is a more ideal tapping groove Refractory materials.
