PROCESS FOR PRODUCING PROTECTIVE LAYER RESISTANT TO WEAR AND TEAR, ON THE SHAPE GIVING SURFACES OF A CONTINUOUS CASTING INGOT MOULD AND AN INGOT MOULD, SO PRODUCED

摘要

In the manufacture of moulds from copper materials for steel continuous-casting installations, a wear-protection layer is produced as a result of the action of a laser. Material for forming the wear-protection layer initially is disposed on the copper mould cavity surface and then subjected to a laser beam. The resulting layer is fused to the mould body and, hence, is resistant to faking off. The material may comprise nickel or chromium, and may include additional metals, non-metals or metallic carbides etc. Solid lubricants may also be added.
