The flame cutting machine should be how to debug?

Cutting machine, there are many different types of cutting machine have different functions and features. Flame cutting equipment is one of them. Many users report that when using flame cutting machine, a lot of friend don't know how to debug the flame. In fact, we just need to know the specific characteristics of the flame cutting equipment to normal. Reduction zone is located in the flame core, and the core of the obvious difference is that it's dark. Reduction zone is composed of carbon monoxide and hydrogen, they cannot be acetylene combustion. Reducing the temperature can reach 3000 or so. External flame is a complete combustion zone, is located in the reduction zone. It is composed of carbon dioxide, water vapor and nitrogen, the temperature is between 1200 and 2500. Oxidation flame is produced in the case of too much oxygen. Flame core is conical, significantly shortened length, hazy outline, dim brightness. Similarly, reduction zone and outer flame has been reduced, the flame is purple blue. With sound, sound is associated with the pressure of oxygen. Oxidation flame temperature is higher than ordinary flame. If you use the oxidation flame cutting, cutting quality will be significantly reduced. Excessive acetylene reducing flame is produced. The flame core no obvious contour, the end of the core has a green edge. According to the green edge, have an excess of acetylene; Reduction zone is very bright, flame core is almost mixed; Outside of the flame is yellow. When acetylene too much, it will start out black smoke, because the fire of acetylene oxygen lack of necessary. The energy of the flame cutting machine preheating flames is closely related to the cutting speed and cutting quality. With the increase of for cutting the workpiece thickness, cutting speed should also increase, the flame energy should also increase, but should not be too strong, especially when the cutting plate, from the burning heat of reaction of metal, cutting get strengthened. At this point, preheat flame front preheating capacity is too large will lead to the upper edge of the slit melting and collapse. If the preheat flame is too weak, steel plate will be not enough energy, which will reduce the cutting speed, and even interrupted cutting process. As a result, the strength of the preheating flames and the relationship between the cutting speed is mutual restrictions. Flame cutting machine commonly used under neutral flame cutting 200 mm steel plate, in order to obtain better cutting quality. When cutting thick steel plate, should be preheated and reducing flame cutting, because reducing flame relatively long, flame length should be at least 1 steel plate thickness. 2 times.
