Problems solved by technology

Because it contains expensive alloying elements such as Cr and Mo, the production cost and production cost are relatively high
Due to the lack of sufficient impact and friction under medium and low working conditions, high manganese steel cannot fully exert its work hardening ability, and its wear resistance is poor; even und

Embodiment Construction

[0039] The chemical composition design of the automobile axle housing steel plate of the present invention is to consider from the following aspects:

[0040] (1) C can significantly increase the strength and hardness of the steel, thereby ensuring the wear resistance of the steel plate. However, if the carbon content in the steel is higher than 0.25%, it is easy to cause the toughness of the steel to decrease, and at the same time lead to poor welding performance. If the carbon content in the steel is low, the hardness cannot meet the requirements after heat treatment, and the wear resistance cannot be guaranteed. Therefore, in order to ensure that it has high hardness, good toughness, excellent cold formability and welding performance, the carbon content is limited to 0.19-0.25%.

[0041] (2) Si can improve the hardness and strength of steel, and at the same time, Si can shift the C curve to the right and improve the hardenability of steel; but too high Si content will prom...

Abstract

The invention discloses a wear-resistant steel plate. The composition of the steel plate includes: 0.19-0.25% of C, 0.70-1.10% of Si, 1.50-1.80% of Mn, 0.20-0.80% of Ti, ≥0.0020 % B, < 0.020% P, and < 0.015% S. On the other hand, the present invention also provides a production device for producing the above-mentioned wear-resistant steel plate, including a smelting device, a slab continuous casting device, a rolling device, and a cooling device. In another aspect, the present invention also provides a production method of the above-mentioned wear-resistant steel plate. The present invention effectively improves the hardenability of the steel plate due to the adoption of an appropriate ferroboron adding device and adding method; in addition, the steel plate has excellent strength, toughness and weldability after heat treatment, and the steel quality is pure, which is beneficial to improving the hardness of the workpiece after heat treatment. service life.

Description

technical field [0001] The invention relates to the field of steelmaking, in particular to a wear-resistant steel plate, a production device and a production method thereof. Background technique [0002] Wear-resistant steel plates for construction machinery are widely used in environments with extremely harsh working conditions, such as mining machinery, coal mining machinery, engineering machinery, cement machinery, metallurgical machinery and other product parts that require high strength and high wear resistance. Excavator, loader, bulldozer bucket plate, edge plate, side edge plate, crusher liner, blade, etc. As China's construction machinery industry is in line with international standards, users have put forward higher requirements for the performance and quality of steel products. Therefore, wear-resistant steel plates must not only have sufficient hardness and wear resistance, but also require high toughness, good processing performance, and welding performance. S...
