Why is the steel plate baked?

If there is too much iron oxide on the workpiece, the melted rust will splash around during gas cutting, and the iron slag will splash into the gun hole of the gas cutting gun, blocking the gas cutting gun. Hydrogen cutting and hydrogen combustion will produce water, and acetylene oxygen cutting will also produce water, which is produced by chemical reaction.

Because oxygen and acetylene are used in gas cutting, there is too much iron oxide on the workpiece, and molten rust will splash around during gas cutting, and iron slag will splash into the gun hole of the gas cutting gun, blocking the gas cutting gun. Acetylene contains hydrogen, which reacts with oxygen to form water.

The principle of flame cutting steel plate is that when the steel plate is heated to a liquid state, molten steel is blown away by oxygen, and iron and carbon in the steel plate are oxidized by oxygen to generate a lot of heat. Heated flame is a violent oxidation exothermic reaction between hydrogen and oxygen, and it is the main component of acetylene (or other fuels)-combustion phenomenon. As a result, water (steam) is produced, which will condense into liquid (water) if it meets cold steel plates (especially in winter). In actual operation, if cutting is carried out on the outdoor water-bearing ground, the heat during cutting makes the water on the ground evaporate, and the cold steel plate also condenses into water, so water can be seen oozing from the cutting seam.
