Quenching Improve the hardness of KB grab dredger steel steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of KB grab dredger steel steel and comprehensive mechanical properties.
The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, KB grab dredger steel. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
