Description
Technical field
The utility model relates to a kind of stainless compound steel plate belt blank spray casting machine, belongs to a kind of continuous casting installation for casting in the technical field of metallurgy industry.The utility model not only can be produced the composite plate made-up belt of stainless steel and mild steel, can also produce the composite plate made-up belt of mild steel and low-alloy steel, different types of non-ferrous metal.
Background technology
In modern metallurgical industry continuous casting technology field, conticaster is very important equipment, because its structure and operation principle have not only determined the length of technological process, also directly affects product quality and production cost.The conticaster that original continuous casting process uses mainly contains three types: promptly fixed conticaster, wheeled conticaster and belt caster, though these conticasters respectively have characteristics, but, all exist certain limitation and shortcoming producing different metal composite plate made-up belt process aspect.
1, the crystallizer of traditional conticaster use mostly is fixed, and its structure is that tubular or four blocks of water-cooled copper liner plates are formed, and copper lining board is all fixed, and strand is relative with copper lining board during work slides, and produces frictional resistance between the two.This frictional resistance has not only limited the teeming speed of crystallizer, also affects the service life of brass, and this conticaster must add vibrating device and draw the device strand smoothly that splits.The conticaster of fixed crystallizer is difficult to use many crystallizers to work continuously in addition, so also just can't produce the composite plate made-up belt of different metal material.
2, wheeled conticaster should solve the frictional resistance problem between strand and the crystallizer, and strand speed also increases, but the side seal problem of wheeled conticaster is still and influence it and promote the use of urgency technical barrier to be solved.Produce with manufacture order kind metal sheet strip because of the wheeled conticaster of tradition is many again, seldom can use many crystallizers to work continuously simultaneously, therefore be difficult to produce the composite plate made-up belt of different metal material.
3, belt caster is same moved further because of cooling off steel band and strand, so also there is not frictional resistance, this obviously improves the strip blank teeming speed.The number of patent application of my application: 200420115454.5 " a kind of synchronous circulation mobile steel band crystallizers " and application number: 200420122186.X " a kind of continuous casting machine for stainless compound steel plate strip blank " are the conticasters that uses many crystallizer continuous operations simultaneously, not only can produce the composite plate made-up belt of stainless steel and mild steel, can also produce the composite plate made-up belt of different nonferrous materials.But structurally still there is uncomfortable part: have relatively high expectations as crystallizer cooling steel band technical performance; Under to cool off steel band long, service load is excessive to influence its service life; The sealing of the cold steel band in both sides and transmission more complicated; Prevent that casting cycle secondary oxidation of steel etc. all is to use the technological difficulties that must solve in the process.
The utility model content
In order to overcome the shortcoming and defect of original technology, the purpose of this utility model is to provide a kind of a kind of stainless compound steel plate belt blank spray casting machine of being made up of six upper and lower two groups of spray to cast devices of branch and commutation tensioning apparatus.Its operation principle is that the spray to cast roller of stainless steel water by the at a high speed cooling of rotation is broken into the low carbon steel plate made-up belt two sides that fine drop is injected in motion, and the molten steel drop is carrying kinetic energy and heat content is deposited on low carbon steel plate made-up belt surface, forms composite bed.This spray to cast machine can be produced stainless steel and mild steel composite plate blanks, can also produce the composite plate made-up belt of mild steel and low-alloy steel, variety classes non-ferrous metal.
