NM500 wear-resistant plate cutting technology has been greatly improved, previously NM500 wear-resistant plate cutting using cold rolling cutting, but this cutting technology to a certain extent is not conducive to the maintenance of NM500 wear-resistant plate plate, while the thickness and hardness of NM500 wear-resistant plate have an impact, because cold rolling cutting has an impact on the physical properties of NM500 wear-resistant plate. So now our NM500 wear-resistant plate factory uses high temperature plasma cutting technology. This cutting technology has little effect on the physical and chemical properties of NM500 wear-resistant plate.

NM500 wear-resistant plate cutting, it is recommended to use plasma cutting plasma cutting is divided into underwater plasma and air plasma cutting two kinds. When the underwater plasma cutting is used, the plasma gas can produce a high temperature of several thousand degrees, the incision of the high-manganese steel plate is rapidly melted, and the oxidation is avoided due to the barrier of water, and the water cools the steel plate in time to prevent carbide precipitation, so that the cutting surface of the steel plate is smooth and smooth, no heat-affected zone, and the cutting quality is better, which is the best choice for cutting high-manganese steel. Air plasma cutting is also available.

NM500 wear-resistant plate can also use the traditional flame cutting When using flame cutting, it is recommended to use the cutting car, according to the thickness of the steel plate, the use of different specifications of the head, the ratio of gas and oxygen is adjusted appropriately (better neutral flame), it is better to start cutting after all adjustment, to prevent the section gap caused by the ignition arc in the middle of the cutting quality. NM500 wear-resistant plate welding high manganese wear-resistant steel plate welding can be selected by manual arc welding method welding rod D256(pile 256) or D266(pile 266) electrode; Before welding, the weld should be polished, the workpiece groove and edge should be cleaned, the rust and oil should be removed, and the welding rod should be dried; When welding, small diameter electrode (generally 3mm-3.5mm) should be selected, small current, high voltage, multi-layer welding, multi-pass welding, fast welding; If DC welding is used, the electrode is connected to the positive electrode; Hammer the weld after welding each layer to improve its resistance to thermal cracking. Running water can also be used for quick cooling.
