Abstract

The invention discloses a cast wear-resistant alloy liner and relates to the technical field of wear-resistant liners. It includes a liner body, the working surface of the liner body is composed of an upper layer and a lower layer, the upper layer is a high-chromium wear-resistant white cast iron layer, and the lower layer is a high-manganese wear-resistant steel layer; the invention adjusts the The content of hardenable elements increases the depth of the wear-resistant layer on the surface of the liner body reasonably, and adjusts the content of molybdenum, nickel, tungsten and other elements to increase toughness and corrosion resistance, and prevent harmful substances such as sulfur and phosphorus in the minerals from affecting the liner. The resulting corrosive wear makes the wear resistance and impact resistance of the liner body organically combined, and can effectively prevent the liner body from breaking due to impact under the working conditions of large drop and strong impact.

Description

technical field [0001] The invention relates to the technical field of wear-resistant lining boards, in particular to a cast wear-resistant alloy lining board. Background technique [0002] The liner is the most common and versatile equipment lining, and it is the last shield to protect the equipment. It has a simple structure but has a great effect. In some heavy industries (such as metallurgy, mining, electric power, cement, chemical industry, ports, etc.) The chute and shovel are directly impacted and ground by the material. If there is no high-quality liner to protect it, it will cause material leakage, and it will cause equipment damage and production accidents, directly threatening the safety and security of the enterprise. Civilized production. [0003] At present, most of the wear-resistant linings in my country are integrally cast with single metal materials. The wear resistance and impact resistance cannot meet the production requirements. The plate consumption i...
