Wear-resistant ceramic elbow outer steel pipe, because the inner corundum ceramic hardness is too high, the hardness reaches HV1100-1400, so the general cutting can not be accomplished, such as oxygen cutting, sawing machine, abrasive sheet cutter and so on.
Wear-resistant ceramic elbow cutting operation precautions:
1. Before operation, the operator must wear insulated shoes and insulated gloves and protective glasses. The equipment must be reliably connected to the ground.
2. Contact arc method, you should first press the button on the gun, and then the nozzle quickly contact cutting wear-resistant ceramic elbow, which is more conducive to lead the arc cutting. Arc difficulties, the air pressure can be adjusted to the lower limit!
3. Pressure reducing valve and air compressor should be drained frequently, cutting can not move at excessive speed to avoid wear-resistant ceramic elbow is not cut through the slag caused by the arc reflection, but also can not make the cutting speed is too slow, so that the wear-resistant ceramic elbow red heat, affecting the quality of the cut. Cutting stops, should first release the button, and then lift the cutter. The above specification has obvious improvement on the service life of the electrode nozzle.
4. Cutting the wear-resistant ceramic elbow should always pay attention to the air pressure, voltage, electrode and nozzle use, do not run out of hafnium wire in the electrode spray copper caused by the electrode and conductive nozzle short-circuit burned cutting gun.
5. Electrode and nozzle life, and the thickness of the plate and operating techniques, under normal circumstances, each electrode can be used continuously for about 1 hour or so.
