Embodiment

[0019] The specific implementation steps of the preparation method are as follows:

[0020] a) Casting half chain link, the half chain link is formed by sand casting process, and its casting process mainly includes: sand mold manufacturing, alloy casting, cooling and shaping, and out-of-the-box repairing;

[0021] The sand mold is molded by machine, and its main components are silica sand, activated bentonite, clay, inactive mud and water; among them, the average particle size of silica sand is 0.12-0.14mm, and the content is 75%-80%; the content of activated bentonite is controlled at 7%-8%; the main component of clay is sodium-based bentonite, its montmorillonite content is about 60%, and the clay content is controlled at 10%-12%; the main components of inactive mud are dehydration bentonite, coal powder particles and Silicon particles, the total amount is controlled between 2% and 3%; the water content must be strictly controlled, and its content should not exceed 3.5%;

Abstract

The invention discloses a preparation method of a high-performance round ring chain. The preparation method comprises the following steps: A) casting a semi-chain ring; b) carrying out thermal treatment on the semi-chain ring; c) welding the round ring chain; d) carrying out stress-relief annealing; and e) carrying out finished product inspection. The preparation method of the high-performance round ring chain, disclosed by the invention is reasonable in working procedure arrangement, simple and convenient in preparation process and moderate in cost; and the prepared round ring chain has the advantages of higher strength, abrasion resistance, corrosion resistance and impact resistance and long service life, so that the allocation and transport of goods is safer and more reliable, and the production process is in order.

Description

technical field [0001] The invention relates to a preparation method of a circular link chain, in particular to a preparation method of a high-performance circular link chain with excellent strength, wear resistance and corrosion resistance, and belongs to the technical field of slings. Background technique [0002] A spreader is a device for lifting goods in a hoisting machine. The most commonly used spreader for lifting items is a hook, and its related accessories include lifting rings, lifting suction cups, clamps and forks. Among them, the lifting suction cup, clamp and fork are used together on the crane, which can be used as a special spreader for a long time, and can also be used temporarily as an auxiliary spreader hanging on the hook to improve work efficiency. The spreader for grabbing bulk materials is generally a grab with jaws that can be opened and closed, and an electromagnetic sucker can also be used to absorb magnetic materials such as metal chips; the sprea...
