Smelting method of 30CrNi3MoV (675): sale the B900FD bulletproof, 30CrNi3MoV steel should be smelted by converter plus external refining or electric arc furnace, and 675 steel should be smelted by electric arc furnace plus VHD or equivalent external vacuum refining.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as sale the B900FD bulletproof, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
