Hard surface surfacing is the process of hardfacing the surface of wear-resistant parts (09CuPCrNi-A weathering steel plate) with hard surface surfacing welding wire. High-hardness flux-cored wire and WD-BX1 professional open-arc flat welding equipment are used for surface surfacing, so that the surface of wear-resistant parts (
09CuPCrNi-A weathering steel plate) is formed with a higher wear-resistant high-chromium composite carbide than the base material Material, and can make the high chromium carbide and the base material well integrated into a whole. The use of this technology will save more than 50% of the purchase cost, and the effective production and use time is more than double the original new product. Because the use of hard surface surfacing technology can reduce procurement costs and prolong the service life of wear-resistant components (09CuPCrNi-A weather-resistant steel plate), it has received widespread attention and application in various industries. The application of hard surface surfacing technology is introduced below based on the actual situation of various industries. Welcome to send email to

The wear-resistant parts of the steel plant (09CuPCrNi-A steel plate) have a very harsh working environment. The high temperature and frequent hot and cold cycles in the production process accelerate the wear and tear of wear-resistant equipment, increasing the maintenance costs of steel plants and the labor intensity of workers. For example, the continuous casting roll in a steel plant is the main body of the continuous rolling mill. During the production process, the continuous casting roll forms the slab by generating extrusion force. This working principle causes the continuous casting roll to be affected by the high temperature and reaction force of the slab, which will cause non-fatigue cracks on the surface of the continuous casting roll, which can be seen straight and even fall off in a sheet. It brings great inconvenience to production operation, affects production efficiency, and even causes production shutdown. Many steel mills know that the purchase of new products takes a long time and the production cost has increased by more than half. Taking a continuous casting roll in a continuous rolling mill as an example, when the roll wears below the optimal productivity, the actual consumption is less than 1/10 of the overall roll, so the 9/10 cast roll scrapping treatment is not economical. Therefore, most iron and steel plants use 09CuPCrNi-A weathering steel plate hard surface surfacing technology, surfacing hard surface alloy on the surface of the scrap roller, until the original surface size of the roller. In this way, the production cost can be reduced by more than half, and the time to resume production can be shortened. In addition, the amount of steel passing increases by 8-10 times, which is economically reasonable.
