摘要
根据轧辊孔型的磨损情况，采用激光熔覆技术对开坯轧辊的孔型表面进行激光硬化处理，形成高质量的表面强化层，显著提高了开坯轧辊的使用寿命。
According to the wearing condition, laser hardening has been carried out on the roll pass surface of breakdown roller by adopting laser cladding technology. High quality surface hardened layer was formed and service life of breakdown roller has been improved obviously.
