The invention discloses a diamond rope saw cutting method for blast furnace residual iron, which includes: installing rope saw: one end of the diamond rope saw which is not connected with the rope saw machine crosses into the blast furnace, and crosses the bottom of the residual iron, then goes around the top of the residual iron, and finally goes through the blast furnace to connect to the rope saw machine; straightening and overhead diamond rope saw located at the top of the residual iron; cutting residual iron: starting rope saw machine, and diamond rope saw. The diamond wire saw cuts the residual iron by walking; as the diamond wire saw moves, the diamond wire saw located near the top of the residual iron near the sawing slot is released periodically until the residual iron is completely cut through. In this way, the wear of diamond wire saw segment without actual cutting effect can be avoided, the unnecessary friction can be reduced, and the cutting ability of diamond wire saw can be prevented from losing due to carbonization and flattening of cutting edge. In addition, the interference of cutting track can be realized, and the smoothness of cutting can be improved. The invention has the advantages of avoiding the reduction of the service efficiency and the service life of the diamond rope saw in the cutting process, and being more safe and effective.

一种高炉残铁的金刚石绳锯切割方法
本专利技术涉及冶金行业高炉大修
,尤其涉及一种高炉残铁的金刚石绳锯切割方法。
技术介绍
金刚石绳锯在切割石材时,绳锯都是通过钻好的贯通孔,直接套在被切割石材上,在切割过程中切割轨迹自行形成不加干涉,对于石材这类材料而言,这样虽然不能将绳锯效率完全表现出来外,但是也不会在使用上产生问题。由于高炉残铁其材料的特殊性,以及高炉内的施工环境,若采用现有的金刚石绳锯切割残铁,对与残铁接触的绳锯断轨迹不加以约束,在切割的过程中将会产生严重的效率问题,严重的可能会导致绳锯中的切割单元金刚石抛光而无法锯切,导致工程失败。经过多次试验验证,目前金刚石绳锯在石材、钢筋混凝土等行业中的使用方法,无法被应用在高炉残铁的切割上。
技术实现思路
为此,需要提供一种高炉残铁的金刚石绳锯切割方法,以解决现有技术中金刚石绳锯切割残铁会严重降低绳锯效率,并大大影响寿命的问题。为实现上述目的,专利技术人提供了一种高炉残铁的金刚石绳锯切割方法,包括:安装绳锯:金刚石绳锯未与绳锯机连接的一端横穿至高炉内,并横穿残铁的底部,然后绕至残铁的顶部,最后穿出高炉连接至绳锯机处;撑直并架空位于残铁顶部的金刚石绳锯;切割残铁:启动绳锯机,金刚石绳锯行走切割残铁;随着金刚石绳锯行走,阶段性释放靠近锯缝的位于残铁顶部的金刚石绳锯,直至完全切透残铁。进一步地,步骤切割残铁中,释放靠近锯缝的位于残铁顶部的金刚石绳锯的时机为,切割残铁的金刚石绳锯与残铁顶面的夹角大于70度前。进一步地,步骤安装绳锯中,撑直并架空位于残铁顶部的金刚石绳锯采用导轮撑直方式。进一步地,所述导轮撑直方式具体步 ...
