%X 加料溜槽是转炉炼钢过程中的主要设备之一，用于炼钢过程中添加副原料，故加料溜槽使用过程中工作环境较恶劣对加料溜槽的使用寿命产生严重的危害。加料溜槽使用周期寿命只有3个月左右，失效形式表现为加料溜槽冷却水管爆裂漏水，并且寿命期内漏水事故频繁发生，需要经常停产检修，严重影响了钢产量。本文加料溜槽冷却水管漏水原因进行可行性分析，研究对导致加料溜槽冷却水管漏水的原因，采取超音速电弧喷涂方法进行防治。<br />
The feeding chute is one of the main pieces of equipment in the converter steelmaking process. As a vulnerable part, the feeding chute is inserted into the transverse feeding port of the converter and is mainly used to add auxiliary raw materials in the steelmaking process. Therefore, the working environment of the feeding chute is relatively bad during use, and its maximum ambient temperature is up to 800？C, which seriously endangers the service life of the feeding chute. The service life of the feeding chute is only about 3 months. The failure form is that the cooling water pipe of the feeding chute bursts and leaks, and the leakage accident occurs frequently during the service life, which requires frequent shutdown and maintenance, which seriously affects the steel output and causes significant economic losses. In this paper, the causes of water leakage of cooling water pipe of the charging chute of converter under the action of high-temperature environment and wear of high particle size by-products are analyzed, and the causes of water leakage of cooling water pipe of charging chute are studied. The method of supersonic arc spraying is adopted for prevention and treatment. The investment in the supersonic arc spraying process greatly improves the high-temperature resistance, wear resistance, corrosion resistance, oxidation resistance and slag resistance of the pipe wall of the feeding chute.
