1. Overview
In material transportation systems in industries such as mining, electric power, metallurgy, and building materials, the pipes, hoppers, coal bunkers, fans, separation equipment, etc. commonly used have serious wear problems, which often affect the use of the equipment. Based on the comparative analysis of various process methods and wear failure mechanisms of wear parts, our company uses self-developed new wear-resistant materials and special processes to produce wear-resistant and impact-resistant composite wear-resistant steel plates, which have been widely used throughout the country. Coal mining, electric power, metallurgy and other enterprises have been well received by users.
2. Technical performance of composite wear-resistant steel plate
High hardness and good wear resistance
The carbides in the wear-resistant layer structure are distributed in a fibrous form, and the fiber direction is perpendicular to the surface, and the hardness can reach , and within a certain range, secondary hardening will occur, further improving the wear resistance, which can reach twice that of ordinary steel plates.
High toughness and good impact resistance
The base material is made of low carbon steel or low alloy steel plate with good toughness and plasticity. The structural characteristics are fibrous distribution of high hardness carbides, which are clad with high toughness using a special process. On the matrix, it has the basic characteristics of high hardness and high toughness composite materials, and has good impact resistance.
The wear-resistant layer and the base material have high bonding strength
The wear-resistant layer and the base material are metallurgically bonded, and the bond is firm and does not fall off.
Corrosion-resistant and high-temperature resistant
Wear-resistant layer material It contains high chromium content and also contains manganese, molybdenum, niobium and other components. The alloy carbide formed has strong stability at high temperatures, can maintain high hardness, and also has good oxidation resistance.
Carry out coal mine safety inspections seriously. Strictly implement the requirements of superiors on safety inspections. In accordance with the requirements of the Shandong Coal Mine Safety Supervision Bureau and the Provincial Coal Industry Bureau, focus on inspection items, focus on lessons learned and identify problems, not only coal mines, but also group companies.
Carry out coal mine supervision and law enforcement in a targeted manner. Establish a major inspection leading group headed by the main leader of the bureau, mobilize the overall situation, list out a timetable, and implement the inspection units and responsible persons to focus on the coal mines that they are worried about, and use various methods such as comprehensive inspections by large corps, surprise secret inspections, etc. While improving the effectiveness of supervision, local coal mine safety supervision departments are urged to implement superior arrangements.
Severe punishments and accountability will be strictly enforced without hesitation or mercy. Violations that violate laws and regulations must be severely punished in accordance with the law, and relevant responsible persons must be strictly held accountable. Places and groups with serious problems must be seriously interviewed, criticized, and exposed. Those who fail to supervise work must be held accountable internally.
