After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to ASTM A573 carbon steel plate full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our ASTM A573 carbon steel plate steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
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 ASTM A573 carbon steel plate, 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.
