Seamless Steel Tube Ion Cutting Processing

Suction import peripheral cold air from outside into the suction opening free import machine and air volume is very big, make seamless steel pipe smoke inhalation and the amount of cold air is greater than the filter effective air volume, thus cutting dust thoroughly absorbed becomes impossible.

This method can be used for large diameter spiral welded tube plasma with a diameter of about 800mm.For the diameter of less than 800mm, the pipe size can't be raised from the pipe, and no internal flap should be installed.In addition, it is necessary to keep the wheel Angle of the accompanying car in line with the inner roll Angle in order to keep the travelling cart with the dust baffle in line with the seamless steel pipe.

Detailed measures:
1.Absorb the appearance and installation of the import.Note that the dust baffles need to be properly positioned after the block.
2. Install the smoke baffle on the spiral steel pipe internal accompanying the car and on plasma cutting at point of about 500 mm gun, stay in spiral steel pipe after the siege, to smoke all absorbed.
For this reason, the design principle of dust hood is:
It is hard to get a smoke from the wind at the inlet, because the separation of the cut is far away from the dust.Required to absorb the import more smoke inlet pipe inside the spiral steel pipe can reach the effect, after the plasma cutting gun point location to add a baffle, the smoke inside stranded in seamless steel pipe, the buffer after a period of time can completely remove clean.

In the case of spiral welded tube plasma cutting, the difficulty of removing dust is:
1.The plasma will produce a large amount of vapor, ozone, and nitrogen oxides in the process of cutting, which will severely contaminate the surrounding environment.The focal point of the smoke problem is how to get all the dust out of the dust and dust, preventing air pollution.
2. The filter of inhaled air volume than the smoke produced by plasma cutting and the amount of internal air duct, should be in ASTM A53 seamless steel pipe within a certain amount of negative pressure cavity, and try not to let outside air into the spiral steel pipe in great quantities, can effectively inhale dust into the dust.
3. After the spiral steel pipe cutting point position will smoke blocked, the suction inlet to avoid cold air into the internal spiral steel pipe, steel pipe internal space form a negative pressure cavity of the spiral, helps the soot emitted, hub is against smoke measures the initiative to design a reliable, does not affect the normal production and use.But in the case of the suction of the moulder, there must be an outer baffle to cover the cold air.
4. Plasma gun nozzle when cutting air to blow out two opposite direction at the same time, so that the smoke from the ends of seamless steel pipeFree Web Content, and is installed in the direction of the spiral steel pipe of a suction mouth is going to pull smoke collection.
