What is the flame cutting process of weather resistant steel thick plate?

Weather resistant steel thick plate with a thickness greater than 50mm are generally flame cut, also called oxygen cutting. The flame cutting process is roughly as follows:

(1) Install a cutting nozzle with appropriate aperture according to the thickness of the cut steel plate;

(2) Adjust the oxygen and fuel gas pressure to the specified value;

(3) Use a cutting igniter to ignite the preheating flame, then slowly open the preheating oxygen valve, adjust the length of the flame white core, and make the flame a neutral flame.

(4) At the starting point of cutting, only the preheating flame is used for heating, the cutting nozzle is perpendicular to the surface of the steel plate, and the tip of the flame white core is 1.5 ~ 2.5mm from the surface of the steel plate;

(5) When the starting point reaches the combustion temperature (glow red), open the cutting oxygen valve, and the cutting can be performed instantly;

(6) After confirming that it has been cut to the lower surface of the steel plate, move the cutting nozzle along the cutting line at an appropriate speed to continue cutting forward;

(7) When the cutting is finished, first close the cutting oxygen valve, and then close the oxygen valve of the preheating flame.
