In the use of wear-resistant plate, hot rolled steel plate NM500, according to the different working environment, the severity of friction and wear is different. Moreover, the wear mechanism is different with different materials and working conditions. The well-known wear mechanisms include adhesive wear, corrosion wear, fatigue wear, erosion wear, fretting wear, impact wear and so on. The corrosive wear of wear-resistant plate refers to the chemical reaction or electrochemical reaction between the workpiece and the environmental medium to form corrosion products.
hot rolled steel plate NM500, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
hot rolled steel plate NM500, Welded pipe plays an important role in modern industrial production and engineering construction, and has become one of the irreplaceable steel pipe products. Welded pipe is a kind of steel pipe made of rolled plate and steel plate after crimping and forming. Therefore, the diameter of welded pipe can be made very large and can be made according to the requirements of customers. Welded pipes can be used for water diversion, transportation of gas, air, oil and heating steam and other generally lower pressure fluids.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the hot rolled steel plate NM500 steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
