Γ13Л高锰钢具有较大的线和体积收缩率及低的导热性,在铸件厚的地方有着粗晶粒金相组织。在设计零件的结构和选择制造工艺时必须考虑到Γ13Л高锰钢的这些性能。现在广泛采用的球磨机衬板存在着一些缺点。零件断面的最大尺寸由27毫米跃升至156毫米。由于Γ13Л高锰钢的线膨胀系数大于2.5%,而导热性比碳钢低4/5倍,所以在上述型式的衬板中,它
Γ13Л high manganese steel has a larger line and volume shrinkage and low thermal conductivity, thickness of the castings have a coarse grain metallographic structure. In the design of the structure of the parts and select the manufacturing process must take into account the performance of Γ13Л high manganese steel. Now widely used ball mill lining there are some shortcomings. The maximum size of the part cross-section jumped from 27 mm to 156 mm. As Γ13Л high manganese steel linear expansion coefficient greater than 2.5%, while the thermal conductivity of 4/5 times lower than carbon steel, so in the above type of liner, it
