Problems solved by technology

At present, stainless steel clad plates, strips, and pipes appearing in some application fields are produced under this market background, but so far, there are still few stainless steel clad Basically, they are high-frequency welded pipes or mechanical sleeves, but the real stainless steel seamless composite pipes are almost invisible. One of the important reasons is that the production of seamless composite pipes is difficult and complicated. It can be said that the traditional solid billet piercing process It is impossible to produce stainless steel seamless composite pipe
Several new methods have emerged in the production field in recent years, such as centrifugal casting, mechanical surfacing, disposable core rod method and spray casting method, all of which can produce stainless steel seamless composite tube blanks, but these existing production methods exist Common disadvantages: the production process is interrupted, many manual operations, low production efficiency, high cost, and it is difficult to achieve continuous, large-scale and automated production

Embodiment Construction

[0031] specific implementation plan

[0032] 1. (see Fig. 1), taking the production of stainless steel inner composite tube billet as an example, when starting to cast billets, first send the dummy bar 36 into the upper crystallizer 10, and simultaneously put the dummy ring on the dummy bar into the lower After the crystallizer is sealed, the stainless steel water 5 is poured into the upper mold 10 through the upper ladle 6 and the upper casting trough 7, and the stainless steel water immediately forms a billet shell under the quenching of the inner and outer molds, and at the same time moves along with the dummy bar. Moving down, when it moves to the outlet of the upper crystallizer, all the molten steel crystallizes into a tube blank, and the tube blank continues to move down and enters the upper traction roller 11. At this time, the spray device 12 sprays steam and water evenly on the tube blank, so that it is subjected to secondary cooling The tube blank continues to move ...

Abstract

The present invention relates to a stainless steel seamless composite hollow pipe billet continuous casting machine. Said continuous casting machine consists of the following five portions: internal crystallizer, upper crystallizer, lower crystallizer, dummy ingot cutting car and turnover roller way. Said invention also provides the connection mode of all the above-mentioned five portion, and provides the working principle of said continuous casting machine and its concrete operation method.

Description

technical field [0001] The invention relates to a stainless steel seamless composite hollow tube billet continuous casting machine, which belongs to near-network continuous casting equipment in the production technology of stainless steel seamless composite pipes in the field of metallurgy. The continuous casting machine is characterized in that two upper and lower vertically installed upper crystallizers 10 and lower molds 18 are used in series through an inner mold 1. It can not only produce stainless steel inner and outer single-sided composite hollow tubes Blanks can also produce double-sided composite hollow tube blanks. The use of this composite hollow tube billet to produce stainless steel seamless composite pipe can save the solid billet piercing process and simplify the production process as follows: composite hollow tube billet→rolling pipe→cutting and sizing, and finally realize the near production of seamless composite steel pipe Final shape rolling. technical b...
