大型冰箱用500MPa级重型冷轧滑轨钢研究

Study on Grade 500 MPa Heavy Cold Rolled Slide Steel Used for High-capacity Refrigerator

采用低合金高强钢和碳素结构钢两种成分设计,试制了大型冰箱用500 MPa重型冷轧滑轨钢。对钢的力学性能、组织和成形性能等进行了对比分析,结果表明,碳素结构钢较低合金高强钢更适用于重型冷轧滑轨钢。

The grade 500 MPa heavy cold rolled slide steel used for a high-capacity refrigerator is trial-manufactured by adopting two kinds of composite designs for the low alloy high strength steel and carbon structural steel. The mechanical properties, micro-structures and forming property of the steel are analyzed based on comparison. Analytical results show that using the composition design for the carbon structural steel is more suitable than that for the low alloy high strength steel in producing a heavy cold rolled slide steel.
