Abstract

The invention discloses a high-strength lifting tool head for buildings, which is prepared by a silica sol casting process and comprises the main ingredients in percentage: 0.35 percent to 0.45 percent of C, 0.25 percent to 0.3 percent of Si, 0.45 percent to 0.55 percent of Mn, 1.1 percent to 1.3 percent of Cr, 0.18 percent to 0.22 percent of Mo, 0.12 percent to 0.15 percent of Ni, 0.4 percent to 0.5 percent of Nb, 0.35 percent to 0.4 percent of W and the balance Fe and trace impurities. The invention discloses the high-strength lifting tool head for buildings, which has the advantages that the ingredient preparation is reasonable, the preparation process is simple and convenient, the cost is moderate, and the integral performance is excellent; and particularly, the performance shown in the strength aspect is superior to that of similar products, so the lifting tool head is more reliable and safer in the use process.

Description

technical field [0001] The invention relates to a spreader head, in particular to a high-strength construction spreader head, which belongs to the technical field of spreaders. Background technique [0002] A spreader is a device for lifting heavy objects 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 spreader for lifting fluid materials is commonly used for buckets and hanging tanks. Unload the molten stee...
