Study Control Method Of Flame Cutting Quality Based On Oxygen-Propane

The flame cutting is used iron oxide produced during combustion temperature to cut carbon steel. It is designed by the torch for burning iron oxide providing full oxygen, which ensures to get good cutting results. Cutting the cost of equipment and cutting thick metal plate is the only effective means of economic, but which has disadvantages in thin plate cutting. Compared with the plasma, the flame cutting heat affected zone of big thermal deformation is larger. In order to cut accurate effectively, operators need to have superb technology in cutting process to avoid metal plate hot deformation in time. Influence factors on the quality of the flame cutting includes flame power and time, preheat the purity of oxygen and oxygen pressure, cutting to the mouth distance and cutting speed, etc.Different thickness of the steel plate requirements different processing, such as the quality, the production and the need to balance the quality requirements of the processing consideration, which can give good priority to the production in different cases, whose cutting parameters is the best. And it needs to study in different cutting parameters and quality changes.Certain parts of the specification mainly are some sorts of strip parts, when thickness changes, its aspect ratio in what range can guarantee the bend in the parts to meet the technological requirements within the range, which can determine whether parts for flame cutting processing or not. And in different processing method, such as single cut processing and cut processing, takes the parts bending deformation degree.This article on the flame cutting machine, CNC system electric control system and servo system and electric control system, those qualities direct influence on the level of cutting quality, which is need to improve quality of the comprehensive research.Finally, combined with several chapters of the design before the Lord and control circuit, the flame cutting machine control system of the experiment circuit is build, and the results of the experiment are analyzed.
