Description
Technical field
The present invention relates to a kind of seamless steel pipe production, more particularly to a kind of more work(with secondary punch function roll shape
Can milling train.
Background technology
In seamless steel tube production field, the effect of Mannesmann piercing mill is solid pipe billet piercing into hollow hollow billet, rolls
Pipe machine acting on and hollow billet be finish-machined to as finished product seamless steel pipe.Both equipments are that production seamless steel pipe is indispensable
Most basic equipment.Tiltedly bundle punch is typically first passed through when producing seamless steel pipe solid pipe billet is pierced into hollow hollow billet, so
Hollow billet is finish-machined to by finished product seamless steel pipe by pipe mill again afterwards.It is mature that it is that seamless steel tube production technology is developed so far
The seamless steel pipe of production technology, the either national defence of production high-quality, military project and important use, or produce the one of low and middle-grade times
As industry and civilian seamless pipe be intended to use this technique, by this whole production technology mistake from raw material pipe to finished product seamless pipe
Found after Cheng Jinhang segmentations, perforating and overlapped and cross section be present in two links of tube rolling, this is overlapping and intersects
Part is necessary for some high-end products, and is completely omissible for some low-end products.It is low in
The seamless steel pipe of class is higher using the technique productions cost.Moreover, for the enterprise of seamless steel tube production chain to be built, equal nothing
One will exceptionally have perforation unit and Tube Rolling Train, and this is invested for product orientation for general industry and civilian producer
Larger, capacity of equipment is superfluous.In addition, if the function of the function of punch and pipe mill is integrated on one device,
Secondary punch function roll shape on existing equipment will no longer adapt to the equipment after integrating, it is necessary to redesign.
In view of it is above-mentioned the defects of, the design people, be actively subject to research and innovation, to found a kind of more work(of new structure
Energy milling train, make it with more the value in industry.
