High-strength wear-resistant low-carbon high-alloy steel lining plate and machining process thereof

Abstract

The invention discloses a high-strength wear-resistant low-carbon high-alloy steel lining plate and a machining process thereof. Each 1t alloy steel lining plate is prepared by the following raw materials: 920 kg of waste steel,12 kg of No. 60 ferromanganese, 12 kg of No. 75 ferrosilicon, 120 kg of ferrochrome, 10 kg of ferromolybdenum, 30 kg of titanium alloy, 12 kg of quicklime and 6 kg of niobium iron, the 920 kg of waste steel is selected, defective products are removed, the powdery No. 60 ferromanganese, the No. 75ferrosilicon, the ferrochrome, the ferromolybdenum and the titanium alloyare added into a rolling wheel type sand mixer, so that the mixture is uniformly stirred; and a scrap steel raw material is added into an electric furnace, the selected 920 kg waste steel and the mixed additive are added into an intermediate frequency furnace, and the waste steel is melted by an intermediate frequency furnace, so that impurities in the waste steel are removed, and the molten metal solution is poured into a liner plate cavity. According to the high-strength wear-resistant low-carbon high-alloy steel lining plate and the machining process thereof, the strength and the wear resistance of the alloy steel lining plate are effectively improved, the working efficiency of the material preparation link in the machining process is improved, the application range of equipment is increased, the lining plate has an elastic pressurizing structure, the service life of the equipment is prolonged, and the lining plate is relatively practical.

Description

technical field [0001] The invention belongs to the technical field of alloy processing, specifically relates to an alloy lining plate, and more particularly relates to a high-strength wear-resistant low-carbon high-alloy steel lining plate and a processing technology thereof. Background technique [0002] The lining plate is used to protect the cylinder body from direct impact and friction of the grinding body and the material. At the same time, different forms of the lining plate can be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material. It is helpful to improve the grinding efficiency of the mill, increase the output, and reduce the metal consumption. When crushing is the main method, the lining plate is required to have a strong ability to push the grinding body, and the lining plate should have good impact resistance. Wear-resistant and easy to deform, most of them have been switched to alloy steel ...

AI Technical Summary

Problems solved by technology

[0003] The existing alloy liner processing technology has certain disadvantages in the process of operation. The alloy liner produced by the traditional alloy liner processing technology has poor wear resistance and low strength, which reduces the use of the alloy liner. The life of the alloy liner is prone to wear in a short period of time. In the material preparation process of the traditional alloy liner processing process, the internal capacity of the roller sand mixer cannot be adjusted, which reduces the flexibility of equipment use. And the traditional roller The weight of the wheel of the wheel sand mixer is relatively large, which reduces the working efficiency of the wheel sand mixer to a certain extent. It is prone to damage during the process, which reduces the processing efficiency of the alloy liner and brings certain adverse effects to users
