Process for clearing metal grinding materials for derusting by using special steel wires for steel wire rope

Abstract

The invention discloses a process for clearing metal grinding materials for derusting by using special steel wires for a steel wire rope, which is carried out according to the following steps: (1), disassembling the steel wire rope into single steel wires and classifying according to the diameters; (2), cutting the steel wires into cylindrical steel wire cutting segments by using a steel wire segment cutting machine; (3), putting the cylindrical steel wire cutting segments into a round casting machine, and repeatedly and circularly casting for 30-100 minutes at a speed of 75meter/second until the cutting segments are round to form steel grits; (4), carrying out roundness separation on the steel grits in a round separation machine; (5), screening the steel grits subjected to the screening by the round separation machine to screen scraps; and (6) packaging and putting in storage. With the adoption of the process method, the produced metal grinding materials have high quality and long service life and are suitable for surface clearing and derusting of various workpieces.

Description

Technical field: [0001] The invention belongs to a method for making metal abrasives, in particular to a process for making metal abrasives for cleaning and derusting by using special steel wires for steel wire ropes. , Background technique: [0002] my country's current metal abrasives mainly include: cast steel shot, steel grit and steel wire cut shot. Among them, the production process of cast steel shot is: heating scrap steel and other raw materials to 1600 ℃ to turn into molten steel, and then atomizing and granulating the molten steel → screening → packaging and storage. The production process of steel grit is: use large-sized cast steel shot through mechanical crushing → screening → packaging and storage. The metallographic phase of cast steel shot and steel grit is as-cast martensite, which is called cast steel abrasive. Because this kind of abrasive naturally has defects such as pores, looseness, and cracks, the breakage rate is high during use, and the surface c...

Problems solved by technology

The metallographic phase of cast steel shot and steel grit is as-cast martensite, which is called cast steel abrasive. Because this kind of abrasive naturally has defects such as pores, looseness, and cracks, the breakage rate is high during use, and the surface cleaning quality of metal workpieces is high. unstable

The steel wire cut shot is cut into small cylindrical sections with steel wire, but its cut surface has sharp right angles, burrs or slopes, which will easily cause the surface roughness of the processed metal workpiece to be too large during use, which does not meet the requirements. And waste a lot of paint, increase the cost input
