Long-service-life tundish integral impact barrel, formula and manufacturing process thereof
The invention relates to a long-service-life tundish integral impact barrel, a formula and a manufacturing process thereof. The long-service-life tundish integral impact barrel is an integral impact barrel and is composed of tabular corundum, fused magnesite, fused white corundum fine powder, a binding agent, active alpha-aluminum oxide superfine powder, silicon oxynitride recovery powder, a composite water reducing agent and explosion-proof fibers, and is prepared through ingredient mixing, wet mixing, vibration molding, curing demolding, baking packaging and the like. According to the long-service-life tundish overall impact barrel, the formula and the manufacturing process thereof, the problems that a slag blocking wall is prone to falling off due to erosion and falling of coatings or dry materials in the later period when a current stabilizer floats upwards can be effectively solved, various physical properties of products are excellent, manufacturing and mounting are convenient, energy-saving and consumption reduction can be achieved, and the service life is prolonged.
本发明涉及一种长寿命中间包整体冲击桶、配方及其制作工艺，为整体式冲击桶，由板状刚玉、电熔镁砂、电熔白刚玉细粉、结合剂、活性α‑氧化铝超微粉、氮氧化硅回收粉、复合减水剂及防爆纤维组成，经配料混合、湿混合、振动成型、养护脱模、烘烤包装等工艺制作而成。本发明的长寿命中间包整体冲击桶、配方及其制作工艺可有效地解决稳流器上浮，挡渣墙后期因涂料或干式料侵蚀脱落易倒伏问题，产品的各项物理性能优异，制作安装方便、节能降耗、使用寿命提高。
