Gas cutting round steel, first from one side to preheat, preheat flame should be perpendicular to the surface of the round steel, start cutting, slowly open the gas cutting oxygen valve at the same time, the cutting nozzle to a direction perpendicular to the ground, and then increase the cut oxygen flow, make the round steel cutting through.
Cutting nozzle at the same time of moving forward, even slightly transverse swing, to widen the incision, slag discharge.
Smaller diameter round steel, zui finish a gas cutting.
If the diameter of round steel, opaque all at one time, can use split gas cutting method.
In order to improve the cutting efficiency of round steel, can arrange several root parallel round steel close to continuous gas cutting.
When burning, will be a first round steel preheating the combustion temperature, using appropriate retroverted cutting torch at a certain cutting speed.
When the cutting torch to 3 -
4 and 6 -
7, the incision of slag will be heated by a round steel surface and make it reach the ignition point, at the beginning of the cut oxygen flow under the action of the round steel cutting process, and to continuously for several root round steel cutting.
Continuous cutting root number depends on the diameter of the round steel and cutting machine cutting torch on the effective stroke.
Laser cutting machine for cutting the pipe material in the process of continuous gas cutting round steel, the actual cutting thickness is constantly changing, thus cutting speed also want to change, to get a good cutting quality.
Practice, often take a relatively suitable average speed as the cutting speed.
In addition, the cutting torch height from 1 -
After three place need to be adjust, as long as you keep in the height of 3, after cutting torch inclination, depends on the diameter of round steel and cutting speed on average, be determined by experiment.
Since only the continuous gas cutting, round steel preheating 1 root, followed by round steel using slag preheating, preheating time accounts for the proportion of small, in the whole cutting and single round steel cutting, accounted for 40% of the whole cutting time - preheating time
Thus, round steel continuous gas cutting, the cutting efficiency can be greatly improved, approximately 1 single round steel cutting efficiency.
