摘要
为满足使用要求,通过研究加热、控轧控冷工艺、重新设定工艺参数、控制表面质量等措施,使用150mm×150 mm的连铸坯开发出轴承钢GCr15盘条。该盘条的金相组织、表面脱碳层、碳化物不均匀性及表面质量等各项指标良好,可满足国家标准要求,且能够保证产品的加热质量,实现安全生产。
In order to meet application demand,the wire rod of GCr15 bearing steel produced by 150 mm ×150 mm slab was developed by measures of studying heating and controlled rolling and cooling process,resetting process parameters and controlling surface quality.Indices of the said wire rod,such as metallographic structure,surface decarburization layer,carbide non-uniformity and surface quality,could meet the requirement by the national standard.The heating quality of the product was ensured and safe production realized.
