Abstract
The utility model relates to a large cross section tubular type crystallizer for continuous casting, which comprises a crystallizer water jacket and a crystallizer copper pipe, wherein the crystallizer copper pipe is in integral structure, the size of the cross section of the utility model is larger than or equal to 250 * 250mm, and the crystallizer copper pipe is a square blank or a rectangular blank with the length of 650 to 1000mm and the taper of 0.6%/m to 1.5%/m and can have a single taper, multiple tapers or a parabola taper. The crystallizer copper pipe in the structure overcomes the quality problem of corner parts of combined crystallizer casting blanks, increases the surface quality of casting blanks and obviously increases the steel passing quantity and the disposable service life. The utility model has the advantages of simple structure, even cooling and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of casting mold for continuous casting, and especially cross dimensions is more than or equal to the tube type mold of 250 * 250mm.
Background technology
(cross dimensions is more than or equal to the design of 250 * 250mm) crystallizers with big section for the tradition continuous casting, generally all adopt the combined type design, its structure is similar to continuous casting crystallizer for plate billet, the crystallizer copper wall is made up of four copper coins, and the cooling water seam is made up of the tank at the copper coin back side and the stainless steel backboard that is attached thereto.This knockdown big section side (rectangle) blank continuous casting crystallizer structure and make all complicatedly, cost is higher, and in the continuous casting production application, its main economic and technical indices (as steel transportation amount, disposable service life and surface quality of continuously cast slab etc.) is not had an advance.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cooling evenly, the continuous casting of low cost of manufacture is with the tube type mold of big section.
For achieving the above object, continuous casting of the present utility model comprises crystallizer water jacket and crystallizer copper pipe with big section pipe formula crystallizer, and crystallizer copper pipe is a monolithic construction, and cross dimensions is more than or equal to 250 * 250mm.
Crystallizer copper pipe is square billet or rectangular bloom, and copper pipe length is 650～1000mm, and tapering is 0.6～1.5%/m, can be single tapering, many taperings or parabola taper.
After adopting such structure, because crystallizer copper pipe is by the disposable monoblock type that is squeezed into of copper ingot, the quality problems in fourplatemold strand bight have been overcome, improved slab surface quality, steel transportation amount, disposable service life significantly improve, and simple in structure, cooling evenly, low cost of manufacture.

1. side plates one among the figure, 2. inner arc plate, 3. outer arc plate, 4. side plate two, 5. surface of internal cavity.
The specific embodiment
Adopt the manufacturing process of little square blank crystallizer copper pipe, silver-bearing copper or deoxidation phosphor-copper or chromium Zirconium copper ingot are squeezed into pipe, carry out annealing in process then, after the annealing pipe extruding become square tube or rectangular tube, become finished product after machined and coating processing, the copper pipe cross dimensions is more than or equal to 250 * 250mm.Crystallizer cooling water seam is formed by tubular type stainless steel water jacket and crystallizer copper pipe.Compare with the box-like crystallizer of traditional group, make simply, cooling has evenly overcome the quality problems in fourplatemold strand bight, has improved slab surface quality.The taper design of crystallizer is the continuous tapering of parabola, also can be designed to single tapering or many taperings, and surface of internal cavity adopts Cr coating or composite deposite, adopts its steel transportation amount of crystallizer and the disposable service life of this spline structure to significantly improve.
Continuous casting has adopted such monolithic construction with big section pipe formula crystallizer, and concrete parameter is as follows:
Crystallizer copper pipe section: 280 * 380mm
Crystallizer copper length of tube: 704mm
Crystallizer copper thickness of pipe wall: 22mm
Conical degree of crystallizer: 1.38%/m
Casting machine radius: 12m
Strand pulling rate: 0.6～0.8m/min
Main casting steel grade: U71Mn
In actual production, the steel transportation amount of this tube type mold can reach 12842 tons, compares with former fourplatemold, and steel transportation amount is significantly improved, and production cost obviously descends.
