我们生产的ЛАЖМЦ70-6-3-1牌号的铜套,是采用离心铸造方法生产的。按照技术条件机械性能要求达到δb≥70公斤/公厘~2,δ≥7%。一般在金属模中铸造的铸件δb≥55公斤/公厘~2,δ≥5.0%;砂型铸件δb≥50公斤/公厘~2δ≥7%,用离心铸造法铸出的铸件机械强度虽然较高,但要达到这样高的性能,只靠用离心铸造 We produce ЛАЖМЦ 70-6-3-1 grade copper sleeve, is produced by centrifugal casting method. In accordance with the technical requirements of the mechanical properties of δb ≥ 70 kg / mm ~ 2, δ ≥ 7%. Generally cast in the mold δb ≥ 55 kg / mm 2, δ ≥ 5.0%; sand cast δb ≥ 50 kg / mm ~ 2δ ≥ 7%, with centrifugal casting castings mechanical strength although more High, but to achieve such a high performance, only by centrifugal casting
