利用铸后余热实现铸铁球淬火(以下简称铸热淬火)大幅度地提高了铸球质量(见本刊1983年第3期),在生产应用中也可取得明显的经济效益(参阅本刊1984年第1期)。铸热淬火铁球与普通铸铁球相比,从球的表面到心部具有硬度高、韧性好、耐磨的特点。铸热淬火铁球的生产与高铬铸钢、高铬铸铁、稀土镁中锰球墨铸铁球的生产相比具有工艺简单、成本低的优点。同时,应用范
The use of residual heat after the cast iron ball quenching (hereinafter referred to as casting hot quenching) substantially improve the quality of the cast ball (see Journal 1983 No. 3), in the production and application can also obtain significant economic benefits (see 1984 Year first period). Casting hot-quenched iron ball compared with ordinary cast iron ball, from the surface to the heart of the ball has a high hardness, good toughness, wear-resistant characteristics. Casting hot quenched iron ball production and high-chromium cast steel, high-chromium cast iron, rare earth manganese manganese nodular cast iron ball production compared with a simple process, the advantages of low cost. At the same time, the application of Van
