Steel wire rope head casting method

Abstract

The invention relates to a steel wire rope head casting method which is characterized in that tin-based bearing alloy is fused, zinc-based complex adhesion promoters are prepared to be used; rope heads at two ends of a steel wire rope are divided into completely divergent broom heads, and the broom heads are washed through steams, blown dry through high pressure wind and placed into the fused bearing alloy for preheating for 40-75s; after preheating, the zinc-based complex adhesion promoters are evenly coated on each steel wire of the broom heads; the broom heads coated with the adhesion promoters are placed into the fused bearing alloy again, evenly stirred and taken out, the broom heads coated with the alloy in advance are placed into a casting mold for casting of conical heads. The steel wire rope head casting method has the advantages of being simple in process, environmentally friendly and fast and convenient to operate, being capable of well ensuring the rope head casting quality and being favorable for overall pulling breaking measurement and detection of the steel wire rope.

Description

technical field [0001] The invention relates to a metal casting method, in particular to a steel wire rope head casting method, which belongs to the technical field of metal product inspection and is used for measuring and inspecting steel wire ropes when they are fully pulled and broken. Background technique [0002] Steel wire ropes are generally used in very harsh working environments, and various technical indicators of steel wire ropes will affect their service life. Therefore, it is very important to measure and test the breaking force of the steel wire rope sample. For example, Chinese Patent Publication No. CN101829764A, the publication date was September 15, 2010, and the name of the invention is a method for casting molten metal at the end of a steel wire rope. The end is made into the shape of a broom head and surface treated. The steel wire rope broom head is cast into a cone shape with a certain temperature and a certain mass ratio of alloy melt, and the test s...

AI Technical Summary

Problems solved by technology

On the one hand, this method requires a lot of time, and cannot perform the full-tension breaking test on the steel wire rope in time.

On the other hand, the use of highly corrosive hydrochloric acid solution will damage the wire rope to be tested, affect the real tension of the wire rope, and have adverse effects on the environment and the health of operators

[0004] The second is that the molten alloy cast by the broom needs to be prepared according to the specific ratio in the application, which not only requires professional metallurgical smelting technology, but also the alloy composition is difficult to control, which cannot well guarantee the quality of the broom casting

At the same time, the casting temperature reaches 450±10°C in summer and 480±10°C in winter, and the temperature above 400°C will cause thermal damage to the carbon steel material, thus affecting the overall breaking force test value of the steel wire rope
