1 前言控制钢水流动的滑板广泛使用具有优良特性的Al2O3-(ZrO2)-C材质产品,但该材质存在的缺点是,钢水中的氧或从滑板面之间浸入的大气等使组织中的碳成分氧化,导致组织脆化。组织脆化的滑板,如果钢或是渣侵润或附着到其组织内,滑动时损伤面将扩大,会影响其寿命。
1 Preface It is widely used in Al2O3-ZrO2-C materials that control the flow of molten steel. However, this material has the disadvantage that the oxygen in the molten steel or the air infiltrating from the surface of the sliding plate causes the carbon Oxidation of ingredients, resulting in tissue embrittlement. Tissue embrittlement of the skateboard, if the steel or slag infiltration or adhesion to its organization, the sliding surface damage will expand, will affect their life.
