Information

Now take you to know about the tube laser cutting machine cut round steel pipe.

 

 

Gas cutting round steel, first from one side of the preheating, the preheating flame should be perpendicular to the surface of the round steel, start cutting, slowly open gas cutting oxygen valve at the same time, the cutting nozzle into a vertical direction with the ground, and then increase the cutting oxygen flow, so that the round steel cut through.When the cutting nozzle moves forward, it should also make a little lateral swing to widen the incision and facilitate slag discharge.Small diameter round steel, zui good gas cut completed.If the diameter of the round steel is large, one cut is not permeable, can use split gas cutting method.

 

 

In order to improve the cutting efficiency of circular steel, several circular steel can be arranged in parallel and closely for continuous gas cutting.When gas cutting, first preheat the first round steel to the combustion temperature, using the appropriate backward cutting torch to cut at a certain speed.When the cutting torch goes to positions 3-4 and 6-7, the slag in the cut will heat the surface of the next round steel and make it reach the burning point. Under the action of cutting oxygen flow, the round steel starts the gas cutting process, so that several round steel can be cut continuously.The number of continuous cutting roots depends on the diameter of the round steel and the effective stroke of the cutting torch on the cutting machine.

In round steel continuous gas cutting process, the actual cutting thickness is constantly changing, so the cutting speed should also change, in order to obtain a good cutting quality.In practice, a relatively appropriate average speed is usually taken as the cutting speed.In addition, the height of the cutting torch should be adjusted from the position 1-3, so long as it remains at the height of 3 in the future, the posterior inclination of the cutting torch depends on the diameter of the round steel and the average cutting speed, which is determined by the experiment.

 

 

Because of continuous gas cutting, only the first round steel, the subsequent round steel using slag preheating, preheating time in the whole cutting proportion is very small, and single round steel cutting, preheating time accounted for the whole cutting time of 40-50%.Therefore, the cutting efficiency can be greatly improved when the round steel is cut continuously, which is about 1.5 times of the cutting efficiency of a single round steel
