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 A283 Gr C ms steel sheet, 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.

Today, the trend of black futures remained high, and the spot market price continued to rise. However, after the rise, the overall turnover of the market weakened compared with the previous trading day, and the transaction of low-cost resources was acceptable. In terms of steel mills, the output of steel mills continues to be high, with firm ex factory prices and relatively saturated orders. A283 Gr C ms steel sheet traders are reluctant to sell at a low price due to the high cost of taking goods, which will support the A283 Gr C ms steel sheet price in the short term. It is expected that A283 Gr C ms steel sheet prices will maintain a high consolidation trend tomorrow.
