Diamond rope saw cutting method for blast furnace residual iron

Abstract

The invention discloses a diamond rope saw cutting method for blast furnace residual iron. The diamond rope saw cutting method comprises the following steps that a rope saw is installed, wherein the end, which is not connected with a rope sawing machine, of the diamond rope saw transversely penetrates into a blast furnace, transversely penetrates through the bottom of the residual iron, is then wound to the top of the residual iron, and finally penetrates through the blast furnace to be connected to the rope sawing machine; the diamond rope saw on the top of the residual iron is straightened in an overhead mode; the residual iron is cut, wherein the rope saw machine is started, and the diamond rope saw moves to cut the residual iron; and the diamond rope saw, which is close to saw seams, located at the top of the residual iron is released in a phased mode along with the moving of the diamond rope saw until the residual iron is completely cut. By adopting the cutting mode, the abrasionof the diamond rope saw section without the actual cutting effect can be avoided, and unnecessary friction is reduced, so that the situation that the diamond rope saw is not capable of carrying out cutting because carbonization happens and cutting edges are flattened is avoided; and moreover, the interference of a cutting track is realized, and the cutting smoothness is improved. The diamond ropesaw cutting method for the blast furnace residual iron has the advantages that the use efficiency and service life of the diamond rope saw can be prevented from being reduced and shortened in the cutting process, and the safety and efficiency are better.

Description

technical field [0001] The invention relates to the technical field of blast furnace overhaul in the metallurgical industry, in particular to a diamond wire saw cutting method for blast furnace residual iron. Background technique [0002] When the diamond wire saw cuts stone, the wire saw is directly set on the stone to be cut through the drilled through hole. During the cutting process, the cutting track is formed by itself without interference. For materials such as stone, although this cannot In addition to fully displaying the efficiency of the wire saw, it will not cause problems in use. [0003] Due to the particularity of the material of the blast furnace residual iron and the construction environment in the blast furnace, if the existing diamond wire saw is used to cut the residual iron, the cutting track of the wire in contact with the residual iron will not be restricted, and the cutting process will be There are serious efficiency problems, which may seriously ca...

AI Technical Summary

Problems solved by technology

[0004] For this reason, it is necessary to provide a diamond wire saw cutting method for blast furnace residual iron, so as to solve the problem in the prior art that cutting residual iron with a diamond wire saw will seriously reduce the efficiency of the wire saw and greatly affect the service life.
