Continuous Pipe Rolling Mill was scheduled for an annual production capacity of 150 000 tons.
The pipe manufacturing process according to MRK-AR technology consists of rolling of thick-walled tubular blanks on a cylindrical mandrel which is moving at a controlled speed rate along the rolling axis.
At the end of rolling process charging tube is removed from a mandrel.
It’s a modern solution applied in tube rolling mills of high productivity and for much larger size ranges of rolled tubes.
Due to the use of a continuous mandrel rolling mill the rolling process is limited to pipes with diameter of less than 244.5 mm.
The technological line is composed of the following devices:
Rotary heating furnace Walking beam furnace Rotary piercing mill
Mill reducer bushings
Continuous mandrel mill Mandrel hoist
Pipe induction reheating unit Stretch reducing rolling mill Walking beam cooling bed
