How To Coat Wear Resistant Steel Plate

NM400 wear-resistant plate needs to be coated before use, this is mainly to protect it from wind and rain during use and prolong its service life. When coating, the surface of the wear-resistant plate needs to be cleaned, so that the coating is more convenient. So we have to do it on a case-by-case basis. What is the specific coating process? Let's see the detailed introduction recommended.

The coating quality of NM400 wear-resistant plate is higher than that of spiral submerged arc welded pipe. The cost of investing in a large unit of production units, workflow, and steel pipe processing is relatively high. Relatively low yield because no repair welding, no head tube allowed. Electric resistance Welded Steel Pipe directly, therefore, the price is higher than the spiral submerged arc welded steel pipe about the total cost from the construction of the pipeline plate, without increasing. Welded pipe seamless mainly includes two aspects of connotation, it is seamless geometry, mechanical method, multi-purpose blowing heat, eliminating internal and external weld hair, followed by physical seamless, application.

Such as heat treatment process, welding, heat-affected zone microstructure and mechanical properties of NM400 wear-resistant plate are based and consistent. Spills are unimportant welding defects, but there are more than 3 mm of super base metal surface unevenness should be ground with a grinding wheel. Spill because when the electrode melts rapidly, the molten metal fluid solidifies along the pool of parent metal. Spills are often formed when the arc welding operation is currently selected too large, or when the draw is too long. Can easily occur in vertical or reverse soldering. There may be a phenomenon that the parent material overflows and penetrates insufficiently. Supervision finds overflow, pay attention to check that there is no seepage defect behind the overflow groove
