NM450 wear plate welding processing and use

Hot-rolled welding processing characteristics of NM450 wear-resistant plate:

Hot rolling process and welding treatment of M450 wear-resistant plate Under normal circumstances, after hot-rolling NM450 wear-resistant plate, some subtle defects in the structure can be eliminated and the steel grains can be refined.

When cutting a thick wear-resistant steel plate, with the increase of the thickness and hardness of the steel plate, the tendency of cracks on the cutting edge increases. In order to prevent the occurrence of steel plate cutting cracks, whether it is hot cutting or cold cutting, relevant requirements should be paid attention to, so as to improve the cutting quality.

The preheating temperature of NM450 wear-resistant plate mainly depends on the quality grade and thickness of the steel plate. The preheating method can be carried out by a flame burning gun, an electronic heating pad, or a heating furnace.

In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point. It should be noted that the entire NM450 wear-resistant plate interface must be uniformly heated to avoid local overheating in the area contacting the heat source.

In addition, some defects such as bubbles, cracks and porosity formed during casting of NM450 wear-resistant plate can also be eliminated under high temperature or high pressure to restore excellent quality.

Secondly, according to the natural properties and characteristics of NM450 wear-resistant plate, scientifically use methods such as sealing, ventilation and moisture absorption to reasonably adjust the temperature and humidity of the warehouse to achieve the purpose of safe storage and reduce various unfavorable factors for NM450 wear-resistant plate. negative impact.

NM450 wear plate has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environment.
Not only that, NM450 wear-resistant plates usually have a variety of operation control, especially in the construction of workshops, the effect is very obvious.
