The preparing work before cutting
1) Check the work place is in line with the safety requirements, special attention should be paid to the ventilation situation, check the acetylene cylinder, tempering preventive device, rubber hose, nozzle is normal, check whether flame cutting equipment connection is good.
2） Dangling add steel MATS, the slit, help remove slag, removed with wire brush or preheat flame cutting line on the surface of a particularly, rust and grease. Due to the cement ground burst when exposed to high temperature, so should pay special attention to steel in concrete can not be cut.
3） Oxygen to adjust to the required pressure. To shoot the suction cutting torch should check the torch for radiation absorption ability. Inspection method is as follows: remove the acetylene gas inlet hose and bent up and open the valve of acetylene and preheat the oxygen valve, put the finger on the torch of acetylene intake pipe joint, if the finger feel draught and adsorption on the acetylene intake pipe joint, indicates a cutting torch radiation absorption ability, can use, on the other hand, surface cutting torch is not normal, check the repair.
4） Check the wind line ( Cut oxygen flow) Check method is to ignite the flame and adjust the hotter the flame, then open the oxygen cutting hair macau, observe the line shape of the wind, the wind line should be straight, clear and have the appropriate length of cylinder. So that the workpiece surface is smooth, size is consistent. If the wind line is irregular, the all valves should be closed, with a needle or other tools trim cutting nozzle inner surface, make it smooth.
2. Cutting operation steps
1) Light the torch, adjust the power of preheating flames and features. Fire power should be adjusted according to the thickness of the class, and materials. Neutral flame commonly used flame.
2） With preheating first flame heating plate edge, stay when cutting surface is going to melt, remove the flame section steel plate edge, at the same time, slowly open the cutting oxygen valve, release cutting oxygen for cutting. When the plate is on the back of slag with oxygen flow shoots a take-off, shows that steel plate has been cutting through. This is should move forward cutting torch gradually.
3） Near the end of the cutting nozzle should go for cutting in the opposite direction of the tilt Angle, so the bottom of the steel plate cutting in advance, make the final cut flush.
4） Quickly close at the end of the cutting, cutting oxygen valve and to raise cutting torch, then close the acetylene valve, zui closed after preheating oxygen valve. If stop cutting work for a long time, oxygen cylinder valve shall be closed, loosen the pressure reducer adjustment screw, and the oxygen release oxygen hose. End cutting work, close acetylene gas valve and pressure reducer landed.
3. The key points of gas cutting operation
1) Position generally holding torch hand in hand, with the right hand thumb and index finger control preheating oxygen valve, this position is easy to adjust the preheating flames, and closed when the tempering is conducive to timely preheating oxygen. Left thumb and index finger cutting oxygen control valves, as well as to master the direction of the role. The remaining three fingers hold smoothly cutting torch mixing chamber.
the operator not bent low, breathing should have rhythm, eyes should be watched the cutter and workpiece, and focus on looking to cut the secant line in front of the mouth, in order to avoid cutting nozzle deviation secant.
2） Cutting thickness 5 mm above the metal cutting nozzle Angle, nozzle and be cut metal surface should be about 10 - 20 degrees Angle, in order to better heat cutting edges, the cutting process is easy to complete. Below 50 mm metal cutting thickness, cutting nozzle should be vertical cut metal surface, and at the beginning if began cutting parts inside, to be on the cutting piece in advance drilling, hole diameter is equal to the cutting width.
3） Try to make the cutting nozzle in the process of cutting process in cutting and cutting surface maintain a constant distance and nozzle Angle.
the cutting process, there may be cutting nozzle produce sound and tempering occur, this could be because of the cutting nozzle is overheating or iron oxide slag splash, cutting nozzle was caused by inadequate supply plug or acetylene. In this case, you should close rapidly preheating, oxygen valve to prevent oxygen to pour into the acetylene tube, temper out. If closed after preheating oxygen valve, the cutting torch also sends a & other; Si si & throughout; Tempering within the noise, the surface cutting torch has not been put out, at this time should be quick to tell escape to the valve closed or acetylene hose at quickly remove the cutting torch, tempering the flame of gas discharge. After processing the Abbey, check the torch of the absorption ability, then can rekindle cutting torch.
the operator moving body position, the valve should be closed cutting oxygen. If the operator of mobile location is in cutting thin plate, the colleagues in closed cutting oxygen valve, flame should quickly leave cutting surface, so as to avoid fire sheet will melt.
