Description

Strong magnetic sucker device applied to scrap steel blanking system

Technical Field

The utility model relates to the technical field of strong magnetic sucker devices, in particular to a strong magnetic sucker device applied to a scrap steel blanking system.

Background

At present, in the converter smelting industry, the increase of steel materials depends on the addition of steel bar heads and iron blocks after the converter to a great extent. In the process of discharging steel in each furnace, on the premise of ensuring the tapping temperature, about 3-4 tons of steel bar heads are required to be added. Two types of steel scrap obtaining modes are mainly adopted, and one mode is that personnel need to be arranged to dig the steel bar heads into a self-made steel bar hopper by using an excavator. And then the steel reinforcement bucket is transported to a position where the scrap steel is added after the furnace by using a forklift. And the other is that the cantilever crane is adopted to absorb, grab and release the reinforcing steel bar head. The above two addition methods mainly have the following problems;

a. if the excavator is used for carrying out the loading and transporting of the reinforcement bucket, firstly, a person with professional driving qualification certificate needs to drive the excavator, at least 6-8 tons of reinforcement heads need to be added into each furnace, and the person is arranged to carry out the loading and transporting operation independently, so that the waste of the person exists. Meanwhile, when the excavator is used, damage to the vehicle is caused to different degrees due to improper use. The service life of the vehicle is reduced, and the maintenance cost of the excavator is increased;

b. if the cantilever crane distribution magnetic chuck is used, due to the fact that the material dead weight is large, an electromagnetic chuck with proper suction force is difficult to have, continuous adsorption is achieved, only the motor can be burnt due to overheating, in addition, the position of the cantilever crane needs to be adjusted in the using process, the difference of the suction amount is large each time, the adjusting position and the lifting time are too long, and the operation efficiency is affected;

c. bulk materials such as alloy, steel scrap are too big in weight, and the acceleration that the blanking produced makes its dead weight bigger, and valve and switch can't effectively close after the unloading, and materials such as steel scrap, reinforcing bar head are mostly irregular shape simultaneously, cause cubic material to block up the feed opening easily.
