How to prevent A573 steel plate high strength structural steel sheet, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.
The main metal material A573 steel plate high strength structural steel sheet used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.
As the thickness and hardness of A573 steel plate high strength structural steel sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the A573 steel plate high strength structural steel sheet from cutting cracks, preheating should be carried out before A573 steel plate high strength structural steel sheet cutting. Special attention should be paid to preheating to make the entire A573 steel plate high strength structural steel sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A573 steel plate high strength structural steel sheet cannot be preheated, the partial preheating method can be used instead.
