由于奥氏体锰钢的导热性低,钢液与酸性耐火材料反应强烈和冷却期间碳化物或珠光体转变相当迅速,因此在它的铸造实践上有一些困难问题。橄榄石砂对防止粘砂有很好的效果,与原来的锆砂粉相比,作铸型涂料是适当的。这些铸件的铸态组织含有大大降低韧性的碳化物和其它转变产物,它们必须在奥氏体化温度时充分地予以溶解。对焊接操作必须作周密的考虑,抑制热量的输入以防止内部裂纹。焊件基体的磷含量也必须控制在一个低的水平上。对大型破碎机等的厚大铸件,如不添加某些合金元素仅仅依靠水淬,则碳化物或珠光体的形成是不可
Due to the low thermal conductivity of austenitic manganese steel, molten steel and acid refractory strong reaction and during cooling carbide or pearlite transformation quite quickly, so its casting practice has some difficult problems. Olivine sand to prevent sticky sand has a good effect, compared with the original zircon sand powder, for the cast coating is appropriate. The castings of these castings contain carbides and other transformation products with greatly reduced toughness, which must be sufficiently dissolved at the austenitizing temperature. The welding operation must be carefully considered, inhibiting the input of heat to prevent internal cracks. The phosphorus content of the weldment matrix must also be controlled at a low level. For large crushers and other large castings, such as do not add some of the alloying elements rely solely on water quenching, the carbide or pearlite formation is not
