- The mini mill possesses a high maneuverability a possibility to
roll the tube of a wide range by small weight lots with
correspondence level of consumer quality.
- High quality of tube as well as the possibility of mill quick
readjustment makes a rolling process to be high effective and
competitive.
- At the customers request the mill can be designed and manufactured
for concrete terms and provision for needs in tube an arrangement of
a mill at the works.

- SMALL COMPACT TUBE ROLLING PLANTS
-
- New Technology and equipment of a small compact tube rolling
plants (CTRP) has been designed for production of thick walled hot
rolled tubes of diameter 25 to 80mm of steel and alloys of different
designation with relation of D/S 3 to 12. The tube getting from the
plant can be used both as finished tube and as tube stock for
consecutive cold deformation.
- The technology so
developed is realized in the equipment of the CTRP including the
following rolling mills:- Two high cross roll pierces with guide non
driving disc and with an individual
drive of rolls, - two high diesher mill with guide non
driving disc and with an individual drive of rolls, block of 6-7
stands of longitudinal rolling of type 3H-450.
- The above mentioned technology and the equipment provide the
production of high quality tubes with close tolerance on wall
thickness and diameter +- 5% to +-0.5% accordingly at the tube
length up to 6M
- In the third cross roll reducing- sizing mill the sizing of a
rough tube is performed
mainly on the diameter. In case of using
the plug the sizing on the wall thickness is also possible.
tube measurement has been shown that the
diameter change on the length is usually
not more than 1%.
