The main production processes of stainless steel pipe fittings are: conventional semi-continuous hot continuous rolling, CSP continuous casting and rolling, medium and heavy plate unit, furnace coil unit. Different processing techniques have good advantages, which can ensure that the stainless steel pipe elbows produced have good function and use.

　　Let's first talk about the processing technology method. When processing stainless steel elbows, when tapping to the size of the thread, it may appear that 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 front and rear taps and the workpiece to be processed can be seen after tapping the end face. The tapped thread part cannot be introduced into the hole normally, 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 micro stainless steel stamped elbow pipe fittings, which will drastically affect the recrystallization level, grain growth and Precipitate, and incur 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 taps and improve the quality of thread processing, the following points should be noted. Stainless steel pipe elbow pipe has a good processing technology, and different processing methods are used in processing. At present, the production processes of stainless steel pipe elbow pipe in China are: conventional semi-continuous hot continuous rolling, CSP continuous casting and continuous rolling, medium and heavy plate Unit, furnace coil unit. Different processing techniques have good advantages, which can ensure that the stainless steel pipe elbows produced have good function and use.

　　To deal with these problems, some users had to stop grinding the front guide of the tap, and before and after grinding the front guide of the tap. Due to the shape change of the front guide after grinding, the tap function will still be affected. The way to deal with this title is the furnace coil mill: the furnace coil mill 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.
