Abstract
The utility model discloses a rectangular casting crystallizer, which consists of a narrow face copper plate, a back plate, a wide face copper plate, a supporting plate and a water tank. The narrow face copper plate and the back plate are spliced into a narrow face assembly by a bolt. The wide face copper plate, the supporting plate and the water tank are spliced into a wide face assembly by the bolts. The steel pouring surface of the narrow face copper plate is an irregular curved surface. The steel pouring surface of the wide face copper plate is also an irregular curved surface. The utility model provides the rectangular casting crystallizer, wherein the cooling strength of the four corner parts of the rectangular casting crystallizer is uniform; a casting blank has no longitudinal crack; and the rectangular casting crystallizer is convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of crystallizer, and especially a kind of four jiaos on steel billet of can solving is because of the cold excessively rectangular casting blank crystallizer that cracks.
Background technology
At present, the sheet billet continuous casting surface longitudinal crack is the technical barrier during a sheet billet continuous casting is produced.The copper coin of continuous casting crystallizer for plate billet waters the steel face two kinds of plane and arcs (vertical direction), and plane copper plate crystallizer is more more than the probability that the steel slab surface longitudinal crack of cambered surface crystallizer casting occurs.Most of people think that the high reason of steel slab surface longitudinal crack probability that plane copper plate crystallizer produces is to change relevant with technological parameter fluctuation.Knowhow for many years and to the research of the crackle origin cause of formation, confirm that steel slab surface center band crackle can reduce the single factors origin cause of formation---it is unique a kind of physics origin cause of formation that cooling shrinkage stress produces the steel slab surface longitudinal crack.The generation of crack stress is the section configuration of structure of mould and slab, determined that four angles are two dimension coolings, the inevitable one dimension cooling of intensity greater than planar section, the cooling difference certainly will make four vertical contraction rates in angle greater than planar section, four angles are vertically shunk the stress that gathers with plane cooling contraction rate difference-product and be converted to lateral stress on the base shells of liquid level primary crystallization, break the initial base shell of liquid level crystallization, initial base shell is broken back stress and is obtained discharging, and this phenomenon interruption repeats.This breaks the stress build up point in steel slab surface centre position (or near), appears at steel slab surface center band so the distribution of longitudinal crack is concentrated, and is commonly called as centre burst.According to above-mentioned crackle genetic analysis,, just can effectively solve slab lobe problem as long as can solve the problem of four bights of crystallizer intensity of cooling inequality.In addition, splice the bolt of wide assembly because size is big, fastening difficulty, dismounting inconvenience.Therefore, design a kind of four bight intensities of cooling evenly, easy accessibility rectangular casting blank crystallizer, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides the uniform rectangular slab crystallizer of a kind of four bight intensities of cooling.
The technical scheme in the invention for solving the technical problem is:
A kind of rectangular casting blank crystallizer, narrow copper plate, backboard, wide copper coin, gripper shoe and water tank by it are formed, narrow copper plate and backboard are spliced into the leptoprosopy assembly by bolt, wide copper coin, gripper shoe and water tank are spliced into wide assembly by bolt, the steel face that waters of narrow copper plate is irregular curved surface, and the steel face that waters of wide copper coin also is irregular curved surface.
The technical scheme in the invention for solving the technical problem can also be:
The upright projection of watering the steel face of narrow copper plate of the present utility model is the curved surface of camber line, and the upright projection of watering the steel face of wide copper coin is the curved surface of camber line.
The upright projection of watering the steel face of narrow copper plate of the present utility model is a hyperboloid, and the upright projection of watering the steel face of wide copper coin also is hyperboloid.
The chord length of the upright projection camber line of the steel face that waters of narrow copper plate of the present utility model is 15～60:1 with the ratio of action, and the chord length of the upright projection camber line of the steel face that waters of wide copper coin is 200～900:1 with the ratio of action.
The steel face that waters of narrow copper plate of the present utility model is a parabola with the intersection of horizontal vertical cutting plane, and the steel face that waters of wide copper coin is a parabola with the intersection of vertical vertical cutting plane.
The bolt of wide assembly of the utility model splicing is a hydraulic bolt.
The bolt head of hydraulic bolt described in the utility model is " ten " word thick stick type bolt head.
The utility model is attached with the stainless steel anticorrosive coat at the bottom of the case of water tank.
Compared with prior art, the utility model four bight intensities of cooling evenly, strand do not have longitudinal crack, easy accessibility.
