重工业厂矿的砖烟囱,因外力和温度的影响,时有发生裂缝现象。当裂缝的宽度或长度超过一定的范围就会妨碍烟囱的安全使用,直接影响生产。当裂缝严重到一定的程度时,就应根据本厂矿的具体情况尽快地妥善处理。现介绍邯钢总厂某轧钢分厂40m加热炉砖烟囱的加固处理。 Due to the influence of external forces and temperature, the brick chimneys of heavy industry factories and mines are often cracked. When the width or length of the crack exceeds a certain range, it will hinder the safe use of the chimney, directly affecting production. When the crack is severe enough, it should be properly handled as soon as possible according to the specific conditions of the mine. The reinforcement treatment of the brick chimney of a 40m heating furnace in a rolling mill branch of the Handan Iron and Steel Plant is introduced.
