摘要
某钢厂有3座260 t转炉,年产能500万t,目前转炉烟道采用LT干法除尘工艺(引进德国技术),在冶炼生产过程中由于烟道温度变化、炉渣及烟气冲刷,造成烟道管磨损腐蚀变薄、部分管道受热变形开裂漏水,制约转炉稳定生产。通过对汽化烟道移动段、冷却段及弯曲段进行在线修复,解决了由于汽化烟道磨损及腐蚀造成的漏水问题,从而缩短了炉役检修时间,降低了设备运行成本。
The flues of the three 260 t converters of a steel plant adopted LT dry dedusting process imported from Germany.During steelmaking production process flue temperature changes and slag and fume flush had worn and corroded the flues and some parts had deformed by heat,cracked and leaked water,which restrained stable production of the converters.Through online repair of the mobile section,cooling section and bending section of the vaporization flue,the problem of water leakage due to flue wear and corrosion was solved,which has shortened converter maintenance period and reduced operation cost.
