Annealing process of NM500 plate

NM500 wear plate is a kind of plate with strong wear resistance. In the processing of NM500 plates, successive annealing is a key skill. Let's explain the problem of successive annealing.
 
If you want to produce high-strength NM500 steel plates, you must apply to the continuous annealing skills, that is, cooling skills. In fact, temperature is a very important factor. In order to prevent the adhesion between the steel coil layers, the temperature of the bell-type furnace is limited, not too high, generally not exceeding 720 degrees. In this case, the production of NM500 plates will also have great limitations.
Generally, the carbon content, manganese content, and chromium content of steels with different properties are different. If the high strength steel plate with a+M composite arrangement is obtained by controlling the composition of the steel and the annealing criteria, its yield strength is It will drop sharply and the tensile strength will also increase.
In the manufacturers of NM500 plates, continuous annealing lines are used, mainly relying on the coexistence of stick cooling and water cooling to jointly achieve the cooling effect.
