Abstract
A kind of benefit temperature device of the Rolling compund steel pipe on Pilger pipe mill, belongs to multiple tube manufacturing technology field, it is characterized in that Pilger cold-rolling mill movable machine frame moves reciprocatingly within the scope of the extreme position of front and back under the drive of crank link mechanism, along roll line.Main heating inductance coil is mounted on extreme position before movable machine frame, the first inductance is mended into the rear extreme position that warm coil is mounted on movable machine frame, then the second inductance is mended into warm coil and is mounted on the inlet rolled on movable machine frame.Advantage: 1. structure is simple, easy to installation and maintenance, saves the expense of foundation of civil work, and cost reduces.2. hot rolling Pilger pipe mill not can guarantee constant temperature rolling, and hot rolling Pilger pipe mill is all huger, the production or blank for minor diameter seamless steel tube, and the utility model is transformed suitable for super-huge, large-scale, medium-sized and small-sized cold pilgered pipe machine.
Description
Technical field
The utility model belongs to seamless steel pipe manufacturing technology field, and in particular to a kind of benefit of Pilger Rolling compund steel pipe
Warm device.
Background technique
For the fluid line used under deep-etching, high abrasion, high work pressure environment, the stainless of high-quality is generallyd use
The seamless steel pipe of steel or high alloy content, this kind of tubing are common seamless steel pipes due to largely adding alloying element, price
Several times or tens times.For many years, tubing user and manufacturer, which have been working hard, seeks through the compound of different metal, to obtain
It is a kind of to be not only able to satisfy harsh use environment but also cheap and good-quality high-performance composite pipe.
Composite bimetal pipe can realize the mutual supplement with each other's advantages of material to the maximum extent, save alloying element, reduce engineering cost,
On the basis of guaranteeing former base pipe properties, corrosion resistance, the wearability of pipeline are improved, extends the service life of pipeline, is
The substitute products of pure stainless steel tube, copper pipe or other corrosion resistance compo pipes.
Domestic composite bimetal pipe research and application are later, although domestic existing part oil gas field uses, apply skill
Art is not perfect, in combination process, efficiently still has biggish gap compared with foreign countries in terms of production and detection technique.It is multiple in foreign countries
It is very fast to close pipe developed recently, main process includes hot rolling compounding method, hot extrusion composite algorithm, casts complex method, is quick-fried
Fried welding complex method, combined bimetal composite tube production method, laser cladding method etc..But technique is all relatively cumbersome,
Cost is also bigger.
Summary of the invention
The utility model aim is to provide a kind of benefit temperature device of Rolling compund steel pipe on Pilger pipe mill, can be effectively
Overcome disadvantage of the existing technology.
The utility model is realized in this way it is characterized in that: Pilger cold-rolling mill movable machine frame is in crank link mechanism
Under drive, move reciprocatingly within the scope of the extreme position of front and back along roll line.Main heating inductance coil is mounted on movable machine frame
First inductance is mended warm coil and is mounted on extreme position after movable machine frame, then the second inductance is mended warm line by preceding extreme position
Circle is mounted on the inlet rolled on movable machine frame.
The utility model advantage and good effect are:
(1) using can arbitrarily temperature control inductance coil, so that the structure of milling train is become simpler, installation and repair it is more square
Just, and the expense of foundation of civil work can be saved, substantially reduces whole cost of investment.
(2) compared with traditional Pilger Rolling compund steel pipe technology, cold Pilger pipe mill cannot achieve the smelting of composite steel tube
Finance is closed.Hot rolling Pilger pipe mill not can guarantee constant temperature rolling, and hot rolling Pilger pipe mill it is all huger for minor diameter without
Stitch the production or blank of steel pipe.
(3) the utility model is transformed suitable for super-huge, large-scale, medium-sized and small-sized cold pilgered pipe machine.
Detailed description of the invention
Fig. 1 is the utility model diagram；
In figure: the first inductance of extreme position 2---- mends warm coil 3---- topping roll after 1-------- movable machine frame
4---- movable machine frame 5---- bottom roll the second inductance of 6---- mends warm coil 7---- roll line
The main heated active coil 10---- crank link mechanism of extreme position 9---- before 8---- movable machine frame.
Specific embodiment
As shown in Figure 1, the movable machine frame 4 of Pilger cold-rolling mill exists under the drive of crank link mechanism 10 along roll line 7
Front-rear reciprocation movement is done in preceding extreme position 8 and rear 1 range of extreme position.Limit position before main heating inductance coil 9 is mounted on
8 are set to go out.First inductance is mended into warm coil 2 and is mounted on rear extreme position, then the second inductance is mended into warm coil 6 and is mounted on moving machine
The rolling inlet of frame 4, in this way, the main heating inductance coil 9 of extreme position is responsible for being heated to rolling by steel pipe before being mounted on
Temperature, the second inductance mend warm coil 6 and mend the heat distributed on steel pipe, carry out excellent rolling.First inductance mends warm coil 2
After the temperature distributed on steel pipe is supplied again, then steel pipe is subjected to reply rolling, protects steel pipe forever during rolling is reciprocal permanent
The lower rolling of temperature, it is ensured that rolling is excellent.
