冷轧带钢板形辊激光熔覆表面强化试验

板形辊是生产高端冷轧带钢的关键装备,其表面性能对保证带钢产品表面质量和提高其自身使用寿命都至关重要.为了提高板形辊辊面的硬度和耐磨性,通过激光熔覆铁基耐磨合金的方式对其进行了表面强化处理,通过试验对比了激光熔覆强化辊面与淬火强化辊面性能.结果表明,在满足硬度要求的前提下,熔覆层的耐磨性比淬火层至少提高20.9％.为研发...

Experiment on laser cladding surface strengthening of flatness roll for cold-rolled steel strip

The flatness roll is the key equipment for the production of high-end cold-rolled strip. Its surface performance is very important to ensure the surface quality of strip products and improve its own service life. To improve the hardness and wear resistance of the surface of the flatness roll, the surface strengthening treatment is carried out by means of the laser cladding iron base wear-resistant alloy. The properties of the surface strengthened by laser cladding and hardened by quenching are compared through experiments. The results show that the wear resistance of the cladding layer is at least 20.9% higher than that of the quenching layer under the condition of satisfying the hardness requirement. A new way for the research and development of surface strengthening technology of cold-rolled strip steel flatness roll has been opened up.
