How to do the cutting work of extra heavy steel plate?
(1) Install a cutter with an appropriate aperture according to the thickness of the cutting steel plate (2) adjust the pressure of oxygen and gas to a prescribed value
In thick steel plate cutting, the temperature descends from the top surface downward. At the beginning of cutting, the oxygen pressure gradually increased, and finally reached the same direction in the thickness of the steel plate. This results in inconsistent combustion in the thickness direction of the steel plate at the cutting starting position, and defects at the cutting starting end of the workpiece. To avoid defects, the following methods can be adopted:
1, use circular feed to increase the length of the leading line to avoid direct entry point. This method has good effect and is widely used in production, but its disadvantage is waste of materials.
2, the use of ignition rod. The method is to add a piece of steel plate to the thickness of the steel plate at the cut-in point, and there should be no gap at the close place. The cutter should be cut through the ignition rod, which will guide the cutting moment flame to the bottom of the steel plate, so that the burning speed of the steel plate is consistent, and the best cutting section surface can be obtained. The ignition rod can be replaced by cutting leftover material. This method reduces the distance between the workpiece and the edge of the sheet, reduces the generation of edge and corner leftovers, and effectively improves the utilization ratio of the sheet metal. The ignition rod is more practical in cutting extra heavy steel plates.

In the cold winter of the economy, with technology and quality, enthusiasm and sincerity proud tide, with the Internet thinking and intelligent manufacturing line offline and high integration. Jinzheng Steel Plate Co., Ltd. is only focusing on one thing, that is, to let customers at the lowest price in the country to purchase the best steel plate processing services in the country. For this reason, Nintaus's iron clad members have been working hard. For you, Datang has no commitment, only the fact that it can stand the test.
One: large stock: steel factory direct, annual inventory of more than 1000 tons, 6-250mm thick steel plate complete, Q235, Q345, 45 # steel plate complete;
Two: processing equipment: CNC cutting, cutting plate, CNC bending, winding. The cutting thickness can reach 250mm, and the cutting surface is 6 meters *18 meters.
Three: processing speed: multiple equipment operation to ensure prompt delivery;
Fourth: save money and save heart: professional steel plate processing, to the maximum extent for different needs of customers set materials, professional technical personnel, as long as an idea, a drawing, Kim Jong can provide quality and quantity of finished products.
