Small-diameter thick wall hot rolling processing system and method

Abstract

The invention relates to a small-diameter thick wall hot rolling processing system and method. The processing system comprises a cold press, a head trimming machine, a heating furnace and a rolling machine, which are arranged in sequence, wherein lifting delivering devices are mounted between every two of the cold press, the head trimming machine, the heating furnace and the rolling machine; the rolling machine adopts a three-roller type rolling machine; three pressing rolls of the rolling machine are mounted on a rack in a guide adjusting manner. The small-diameter thick wall hot rolling processing method comprises the following steps: a, sorting; b, stamping; c, head trimming; d, heating; e, rolling; f, surface checking. The processing system is scientific in design, simple in structure, high in reliability, convenient in equipment operation and diversified in function, through the adoption of the processing system and the processing method, the problem that the small-diameter thick wall cold rolling is hard to manufacture is solved; through the adoption of the processing system, various small-diameter steel pipes can be produced, the processing speed can be effectively increased, and the processing quality and the efficiency can be improved.

Description

technical field

[0001] The invention belongs to the field of steel pipe processing, in particular to a small-diameter thick-wall hot coil processing system and method. Background technique

[0002] In modern times, many high-standard thick-walled steel pipes are used in projects such as offshore platforms and bridge construction. At present, due to the large thickness of the steel pipe wall, it is difficult to produce small-diameter steel pipe coils in the processing of thick-walled steel pipes, and it can even be completed with . Customizing small-diameter products requires custom-made molds, and the cost is high, especially when customizing small-batch small-diameter steel coils, the profit is low and the cost is too high and often cannot be produced.

[0003] After searching, the following similar patent technologies were found:
