压缩机高锰钢平衡块和压缩机高锰钢平衡块制作方法
摘要：
本发明提供了一种压缩机高锰钢平衡块和压缩机高锰钢平衡块制作方法，属于压缩机技术领域。它解决了现有的粉末冶金高锰钢平衡块的制造成本高的问题。本压缩机高锰钢平衡块采用合金粉末压制成型和高温烧结定型，合金粉末由高锰钢粉末和润滑剂混合而成，高锰钢粉末由以下化学成分组成并以重量百分比计算，C：≤1.0%；Si：≤0.9%；Mn：15%‑21%；S：≤0.03%；P：≤0.06%；余量为Fe。本压缩机高锰钢平衡块和利用压缩机高锰钢平衡块制造方法生产的压缩机高锰钢平衡块均具有制造成本更低，产品品质更高的优点。同时还具有压缩机高锰钢平衡块精度高，密度与铸造成型平衡块密度接近的优点。
摘要（英）：

The invention provides a compressor high manganese steel balancing weight and a manufacturing method thereof, and belongs to the technical field of compressors. The problem of high manufacturing costof an existing powder metallurgy high manganese steel balancing weight is solved. Alloy powder pressing molding and high temperature sintering molding are adopted in the compressor high manganese steel balancing weight, alloy powder is formed by mixing high manganese steel powder and a lubricant, and the high manganese steel powder is composed of the following chemical components of C with the weight percentage being less than or equal to 1.0%, Si with the weight percentage being less than or equal to 0.9%, Mn with the weight percentage being 15% to 21%, S with the weight percentage being lessthan or equal to 0.03%, P with the weight percentage being less than or equal to 0.06% and the balance Fe. The compressor high manganese steel balancing weight and compressor high manganese steel balancing weights produced by using the manufacturing method of the compressor high manganese steel balancing weight have the advantages of lower manufacturing cost and higher product quality, and meanwhile have the advantages of high precision of the compressor high manganese steel balancing weights and the density approaching that of a casting forming balancing weight.
