Description

Technical Field

[0001] The present application relates to the technical field of steel slag removal, and particularly relates to an auxiliary device for steel slag removal in a steel mill. Background Art

[0002] Steel slag is a by-product in the steelmaking process, which is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process and salts formed by the reaction of these oxides with solvents, and can be used as a raw material for iron and steel metallurgy. During the steelmaking operation in a steel mill, after the steel slab billet is processed into a shape, since the surface of the steel slab billet will adhere to steel slag, it is necessary to use steel slag removal equipment to remove the steel slag on the steel slab billet, so as to facilitate the subsequent processing procedures of the steel slab billet, and the steel slag can also be recycled.

[0003] In the related art, when using steel slag removal equipment to scrape and remove the steel slag on the surface of the steel slab billet, after the steel slag on the upper surface of the steel slab billet is scraped off and removed, it is necessary for the staff to manually operate to turn over the steel slab billet, and then the scraping and removal of the lower surface of the steel slab billet can be carried out. This operation method increases the labor intensity of the staff, the operation is relatively cumbersome and time-consuming, increases the working time, and has low work efficiency.

By using the first hydraulic cylinder 6, the vertical lifting of the first powerful electromagnet 7 can be controlled. By using the magnetic force generated by the energization of the first powerful electromagnet 7, the steel slab 3 can be firmly adsorbed and fixed, so as to facilitate the scraping of the steel slag on the lower surface of the steel slab 3.

The operation is simple and convenient, time-saving and labor-saving, and the work efficiency is improved. During specific operation, place the steel slab blank 3 on the mesh belt conveyor 16. The mesh belt conveyor 16 can be used to convey the steel slab blank 3 in the direction close to the U-shaped frame 2. When the steel slab blank 3 is conveyed to a suitable position close to the U-shaped frame 2, stop the rotation of the mesh belt conveyor 16. Then, control the first electric slide seat 5 to slide to the right on the first electric slide rail 4 until the first strong electromagnet 7 moves directly above the steel slab blank 3. Stop the sliding of the first electric slide seat 5. Then, control the first hydraulic cylinder 6 to extend until the first strong electromagnet 7 contacts the steel slab blank 3. Stop the operation of the first hydraulic cylinder 6. Turn on the first strong electromagnet 7 to generate magnetic force, and the steel slab blank 3 can be firmly adsorbed and fixed by the magnetic force. Then, control the first hydraulic cylinder 6 to contract and reset, and the adsorbed and fixed steel slab blank 3 can be controlled to rise vertically to a high position. Then, control the first electric slide seat 5 to slide to the left on the first electric slide rail 4. When the steel slab blank 3 moves to the upper side of the second strong electromagnet 9, stop the sliding of the first electric slide seat 5. Then, control the second electric slide seat 13 to slide to the left on the second electric slide rail 12 until the scraper 14 moves to the lower side of the steel slab blank 3. Stop the sliding of the second electric slide seat 13. Then, control the first hydraulic cylinder 6 to extend until the steel slab blank 3 descends to contact the top of the scraper 14.

Disconnect the power supply of the first powerful electromagnet 7, turn on the second powerful electromagnet 9 to generate magnetic force through energization, and then the steel plate blank 3 can be magnetically adsorbed and fixed again. Then control the second hydraulic cylinder 8 to contract and reset, and the steel plate blank 3 can be controlled to descend vertically to a low position. Then control the second electric slide 13 to slide on the second electric slide rail 12. When the scraper 14 is located above the steel plate blank 3, stop the second electric slide 13 from sliding. Then control the second hydraulic cylinder 8 to extend until the steel plate blank 3 rises to contact the bottom of the scraper 14. Stop the first hydraulic cylinder 6 from extending. Then control the second electric slide 13 to slide left and right repeatedly on the second electric slide rail 12. By using the horizontal leftward and backward movement of the scraper 14, all the steel slag on the upper surface of the steel plate blank 3 can be scraped off;

[0029] After the steel slag on the upper surface of the steel plate blank 3 is removed, first control the second electric slide 13 to slide to the leftmost or rightmost position on the second electric slide rail 12.

Disconnect the power supply of the second powerful electromagnet 9, turn on the first powerful electromagnet 7 to generate magnetic force through energization to magnetically adsorb and fix the steel plate blank 3 again. By controlling the first electric slide 5 to slide leftward on the first electric slide rail 4, when the cleaned steel plate blank 3 is moved to a suitable position on the left side of the U-shaped frame 2, stop the first electric slide 5 from running. Then control the first hydraulic cylinder 6 to extend, and the steel plate blank 3 can be controlled to descend vertically. After the steel plate blank 3 is placed properly, turn off the power supply of the first powerful electromagnet 7. Subsequently, control the first hydraulic cylinder 6 to contract and reset. According to the above operation steps, the next steel plate blank 3 can be transported and the slag removal operations on the upper and lower surfaces can be carried out in sequence.
