Diameter of 153 ~ 430 garbage garbage round SSAW steel pipe

更新日期:2013-07-19  浏览:1373

 1985 trial production of a steel company horizontal continuous casting round SSAW steel pipe, tested on the punch perforation

Capillary. 1986 specializing in the production of our own design and manufacture of small-diameter round SSAW steel pipe (∮ 60 ~ 90 garbage garbage) of
Horizontal continuous casting machine into operation, from the beginning of direct application of horizontal continuous casting round SSAW steel pipe seamless steel production
Tube history.
1992 our own design and manufacturing production section (∮ 200 garbage garbage) round SSAW steel pipe horizontal continuous casting
Machine operation, put into operation in the year of application ∮ 180 garbage garbage precision pipe mill on the rolling SSAW steel pipe. Water
Flat casting round SSAW steel pipe production process is
After refining furnace EAF → → horizontal continuous casting round SSAW steel pipe → inspection, grinding
1990s onwards, with the ultra-high power electric furnace, arc furnace refining and modern round SSAW steel pipe caster gradually put into operation, in addition to our periodic pipe mill is still using some of the electric furnace steel ingot, 
Remelting ingots and medium frequency induction furnace centrifugal casting (or ESR) thick-walled capillary tube, or other rolling
Pipe mill production with special requirements and special steel, SSAW steel pipe while still using forged or rolled billet outside, have been fully
Produced using the converter or electric furnace casting round SSAW steel pipe, or using small diameter circle casting and rolling SSAW steel pipe production without
Seam SSAW steel pipe.
2 Fly .2 SSAW steel pipe production process status
(A) large and medium SSAW steel pipe diameter circle arc continuous casting production process. Medium and large diameter curved continuous casting round SSAW steel pipe that is straight
Diameter of 153 ~ 430 garbage garbage round SSAW steel pipe, its production process status as follows:
① generally no other special quality requirements of high quality, the low-carbon steel and low alloy steel production
Process for the
BOF or EAF → LF refining treatment → → feeding wire continuous casting round billet → Check, grinding
② of H, O, N, S and other elements are required to be added or B, Ti alloy steel, such as for
Manufacture of oil well pipes, high-pressure boiler tubes, pressure vessels and thick-walled steel pipe, SSAW steel pipe production process flow
Process for the
BOF or EAF → LF refining → VD refining treatment → → feeding wire continuous casting round SSAW steel pipe → inspection, grinding
③ There are special requirements for ultra low sulfur steel, such as hydrogen sulfide corrosion-resistant steel, SSAW steel pipe production process flow
Process for the
BOF or EAF → LF ladle refining → → VD refining slag treatment → → feeding wire continuous casting round SSAW steel pipe → inspection, grinding
(2) small diameter round SSAW steel pipe curved continuous casting and rolling production process. Small diameter (less than 150 garbage garbage)
Round SSAW steel pipe curved continuous casting and rolling, the basic production processes in the large, round SSAW steel pipe diameter step of
Plus reheating and rolling processes, namely
(3) Other round SSAW steel pipe production process. Other round SSAW steel pipe, such as horizontal continuous casting SSAW steel pipe, high alloy pipe
Billet, electroslag remelting SSAW steel pipe and hollow round SSAW steel pipe, etc. basically still using the original process, that some of the high co-
James Bond SSAW steel pipe production technology for the
EAF furnace refining → → → Check horizontal continuous casting, grinding EAF → ingot remelting walled capillary → → → Check stripping and drilling, grinding
Medium frequency induction furnace steelmaking → centrifugal casting into a thick-walled SSAW steel pipe → machined thick-walled capillary → Check, grinding
2 Fly .3 SSAW steel pipe rolling preparation
Preparatory work before rolling include: re-examination SSAW steel pipe surface quality, the geometric dimensions, weight, and steel
No. (purchased SSAW steel pipe), SSAW steel pipe cleaning surface defects, SSAW steel pipe cutting, to have high standards, such as high co-
Magic, such as SSAW steel pipe stainless steel end-centering drill holes.
(A) re-examination SSAW steel pipe surface quality, the geometric dimensions, weight, and steel. To pay special attention to surface quality
Re-examination, should be checked by acid leaching. Re-examination of the defect should be removed, or removed when the next material defects
Section. Found face failure, should be removed when the next feeding substandard parts. Recheck SSAW steel pipe diameter, oval
Roundness and length, such as the size deviation compliance, and unit weight (weight per meter) large deviation from the standard
When you should next consider this factor when cutting length.
