Sawing process of A588 weathering steel plate

A588 weathering steel plate is one of the most commonly used weathering steel plates in bridge construction because of its good characteristics.

The sawing process of A588 weather-resistant steel plate is the same as that of ordinary carbon steel plate, that is, the saw blade used is ordinary carbon steel saw blade. Such as 18-22% chromium-containing alloy carbon steel saw blades, etc., are divided into different types according to different sawing equipment. For example, band saws can be divided into high-speed steel saw blades and stainless steel saw blades.

If you need to cut thin A588 weathering steel plate more accurately and efficiently, you should use a plasma cutter. Plasma cutting has fast cutting speed, good cutting surface, no sparks, no burrs, suitable for cutting A588 weathering steel sheet. In the process of sawing A588 weathering steel plate, the amount of cutting should be as small as possible. Extensive stock removal is usually not required when machining thin plate. Pay attention to cooling and ensure that the cutting temperature is not too high.

If the cutting amount is large during the sawing process of A588 weathering steel plate, careful consideration should be given to the cooling mode. Cooling mode has a great impact on saw blade life, cutting speed and cutting surface quality. Generally, compressed air and emulsion are used for cooling A588 weathering steel plate. It should be noted that the emulsion used must be a special emulsion with low flash point such as kerosene emulsion or high oil emulsion. The amount of emulsion used is determined according to the size of the cutting amount.

In order to improve the sawing accuracy of A588 weathering steel plate, it is often necessary to perform machining operations such as trimming and chamfering after sawing. The sawing mill used shall ensure a high machining accuracy. In order to ensure the positioning accuracy and sawing accuracy of the sawing machine, the temperature of the sawing mill should be kept consistent to prevent thermal expansion and contraction which may affect the machining accuracy.

In addition, the A588 weather-resistant steel plate should pay attention to sharpening the saw blade during the sawing process to prevent the saw blade from breaking. The saw blade should be cleaned and maintained regularly to prevent the adhesion of saw chips and ensure chip removal. In order to ensure the sawing accuracy, the saw blade should be checked regularly for broken teeth or cracks.
