Increasingly serious environmental pressure forces steel and iron industry must be towards energy-saving, green Road Development.Wherein steel-making continuous casting ring
Section improves hourly output, hot sending slab realizes that it is effective for reducing the thermal loss of high temperature slab with the seamless interfacing of steel rolling process
Energy-saving means.
The existing drawing speed of billet caster is not able to satisfy the process requirements that continuous casting is even pricked, due to determining conticaster pulling rate
Key equipment be crystallizer, and the core component of crystallizer is crystallizer copper pipe and water jacket.Therefore, the height of Yao Shixian conticaster
Pulling rate, core technology are exactly that the cooling efficiency of cooling water is improved under limited copper pipe length and section, this is to crystallizer water
It covers and designs and manufactures that more stringent requirements are proposed hydrous water seam dimensional accuracy, water seam uniformity etc. between copper pipe.
The integral water jacket of the high pulling rate crystallizer water jacket of tradition designs and manufactures mode, and test proves it, and there are the following problems
Need to solve: 1, high pulling rate water jacket requires whole drawing molding, water jacket difficult forming, it is desirable that manufactory must have large-scale pressure
Machine or drawbench, and must have skilled operator to complete, general crystallizer manufactory does not have this ability；2,
Water jacket uses stainless steel material substantially, is deformed rear rebound degree height, whole drawing water jacket inner cavity dimensional accuracy after molding is very
Difficulty reaches design requirement, and the elongated band rectangular embedded SMA actuators of arc are also highly difficult, therefore the yield rate of whole drawing molding water jacket
Very low, yield rate is less than 70%, and this considerably increases the manufacturing costs of equipment；Finally water jacket is manufactured even if 3, overcoming difficulties
Out, but since its precision is not high, it is difficult precisely to cooperate with copper pipe shape in assembling stage discovery water jacket inner cavity, part copper pipe
It needs through multiple reconditioning, or even could be packed into water jacket using nonconventional approaches, assembly is extremely difficult, and water seam precision is difficult to
Reach design requirement, the slab quality of production is caused to cannot meet the technological requirements, finally constrains the promotion of conticaster pulling rate.
For this purpose, it is proposed that a kind of next dissection type water jacket for the high pulling rate crystallizer of continuous small-billet casting solves above-mentioned ask
Topic.

1, dissection type water jacket is compared with traditional water jacket, and molding is more easier, and metal plate bending or impact style molding can be used,
Molding technique is highly developed；
2, subdivision composite structure is conducive to assembly；
3, after the molding of left and right water jacket, open structure facilitates lathe to be machined out inner cavity, and miniature numerical control lathe is just full
Sufficient process requirements；
4, water jacket spacer flanger is individually processed, center opening size and four side wall rounding off of water jacket inner cavity, and interior outer arc is
Arc surface (flange thickness 20mm or so can be nearly inclined-plane), left and right sides is to face directly, is easily worked, and precision can also be guaranteed；
5, upper and lower water jacket assembly connect with water jacket spacer flanger and is connected by screw bolts, and positioning pin or limited block finally position,
It is easy to check and adjust accurate measurement, it is ensured that the precision of the entire cavity size of water jacket；
6, upper and lower water jacket assembly and water jacket spacer flanger are permanently limited with weldering limited block, and accurate positioning is permanently effective.
The dissection type water jacket moulding process of the utility model is mature, and entire process of manufacturing is compared to integral water jacket machine hardly possible
Lower and of less demanding to lathe, high yield rate is spent, the available effective control of the cost of processing is more most important to be to ensure that
The form and dimensional precision of water jacket inner cavity, can satisfy the requirement of high pulling rate crystallizer.
