Cold Rolled Seamless Steel Tube Production Process

Date:2017-01-10      Views:383Time(s)      Label:cold rolled seamless steel tube, seamless steel tube, carbon seamless steel pipe    

Cold rolled precision seamless steel tube (GB3639-2000) is a kind of seamless steel tube used for precision mechanical structure, hydraulic equipment and the steel sleeve with high precision and good surface.

High precision cold drawn precision steel tube is a new type of steel varieties, and its main characteristic is high precision. There are usually two kinds of production process including two roll mill and three roll mill production, the precision of the three roll mill production of cold rolled seamless steel tube is higher, but the price is relatively a few higher.


Characteristics

Application of high precision cold drawn precision steel tube saves steel, improve processing efficiency with energy saving. High precision cold drawn seamless steel tube has inner and outer diameter size accuracy (tolerances) strictly, both inside and outside surface roughness, roundness, good straight degree and can greatly save the machining time, improve material utilization, at the same time to improve the quality of the product.


Material

20#, 45#, 16Mn, 40Cr, 12Cr1MoV, etc.


Production process

Cold rolled precision seamless tube: pipe billet – inspection – cutting – heating – perforation – pipe rolling – cooling – inspection – acid cleaning, lubrication – cold rolling mill rolling – anaerobic treatment – precise straightening – head cutting, chamfering – nondestructive testing – inspection – antirust processing, packaging – pounds, put in storage.
