What are the production processes and specific processing methods of stainless steel pipe fittings?
Conventional semi-continuous hot continuous rolling, CSP continuous casting and rolling, medium and heavy plate units, and furnace coil units are different processing technologies. Each processing technology has a good advantage. It can ensure that the stainless steel pipe elbows produced have good performance and use.
In the processing of stainless steel elbows, when tapping to fit the thread size, there may be a situation where the end surfaces of the two taps collide. The reason is that the base surface of the tap is longer. In this situation, it is necessary to shorten the end face of the tap, but the shortened end face may adversely affect the function of the tap. The relationship between the tap and the workpiece to be processed before and after the end face of the tap is shortened can be seen. After the end face is shortened, the threaded part of the tap cannot be normally introduced into the hole but is pressed into the hole by the end face, which affects the function of the tap.
On the furnace coil mill, the thermomechanical history of stainless steel stamped elbow pipe fittings has changed significantly, especially in the production of stainless steel stamped elbow pipe fittings, which will drastically affect the recrystallization level, grain growth and precipitation produced on the finishing mill. And it incurs violent changes in the ultimate microstructure and function of the entire length of stainless steel stamped elbow fittings. When grinding, be sure to adhere to the original geometric shape of the front guide, it is best to use a tap shovel grinding machine to stop grinding.
The best way to deal with a longer tap base is to customize a tap with a shorter base according to the specific requirements of the thread being processed. In order to extend the service life of the tap and enhance the quality of thread processing, it should be noted that stainless steel pipe elbows have a good processing technology, and different processing methods are used in processing.
In order to solve these problems, consumers have to stop grinding the front guide of the tap, and before and after grinding the front guide of the tap. Due to the shape modification of the front guide after grinding, the tap function will still be affected. The way to deal with this problem is the furnace coil mill, which includes a reciprocating roughing mill and a 4-roll reciprocating finishing mill. Two hot coil mills were installed on the feed lines on both sides of the finishing mill.
