A kind of high chromium alloy composite wear-resistant steel plate and its production process

Abstract

The invention discloses a high-chromium alloy composite wear-resistant steel plate, which comprises: a base plate, the base plate is made of steel, and the base plate has an upper surface and a lower surface; On the upper surface of the substrate, the thickness of the substrate is 5-15cm, the thickness of the high-chromium alloy composite wear-resistant layer is 4-30cm, the steel is Q235 ordinary carbon steel or Q345 ordinary carbon steel or stainless steel, and the high-chromium alloy composite wear-resistant Layers consist of non-metal elements and metal elements. In the present invention, the surface of the high-chromium alloy composite wear-resistant layer prepared by it is smooth and smooth without cracks, and its high temperature resistance, corrosion resistance and wear resistance are more than twice that of the current domestic open-arc welding process composite wear-resistant plate, which can meet the needs of ports, power plants, The use requirements of mining, metallurgy and other industries can be widely used in ports, power plants, mines, metallurgy and other industries, making up for the situation that some important construction machinery construction projects in China rely on imported wear-resistant steel plates.

Description

technical field

[0001] The invention relates to the technical field of wear-resistant steel plates, more specifically, it relates to a high-chromium alloy composite wear-resistant steel plate and a production process thereof. Background technique

[0002] A submerged arc welding machine is a welding machine that uses an arc to burn under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke and dust make it the main welding machine in the production of pressure vessels, pipe section manufacturing, and box-type beam-column steel structures. In recent years, although many kinds of high-efficiency and high-quality new welding machines have appeared successively, the application field of submerged arc welding machines has not been affected in any way. From the perspective of the weight of deposited metal of various fusion welding machines, submerged arc welding machines account for about 10%,...
