<p>The method is used in metallurgy and the mechanicalengineering for the repair of moulds, bottom plates, bottom gatesand ladles used for the pouring and transportation of metal andslag smelts. As a result of its application the repair works areintensified, the quality of the repaired equipment is improved,the costs for the restoration of the equipment are reduced and thecosts of the turned out end products are lowered. By the methodany faulty surface is fixed in advance by mounting of doubleT-shaped plates, is roughly fire-treated and is finely treated byemery wheel. There follows welding with electrodes havingdiameters from 4 to 8 mm and power of the supply transformer from27 to 70 kVA.5 claims, 2 figures</p> |
