Description
Technical field
The utility model belongs to metallurgical equipment, is casting mold for continuous casting, particularly relates to the crystallizer of the near net shape continuous casting base of compound section.
Background technology
Traditional continuous cast mold is generally fixed, and metal passes through from crystallizer, forms certain thickness base shell.Fixed crystallizer is because there is relative motion in the crystallization wall between the base shell, produce frictional resistance, so casting speed is restricted, particularly for the base type of section complexity, base type as I-steel, H shaped steel, because surface area is big, frictional resistance is bigger, is difficult to ordinary production with traditional fixed crystallizer.
For head it off, comparatively advanced in the existing technology is to adopt horizontal motion crystallizer and produce the double-roll type crystallizer that strip is used.Be characterized in that crystallizer is the chain that has rectangular recess of horizontal movement, add cover plate above the groove, form the crystallizer cavity.It is reported that U.S. Niu Ke company has developed double roller continuous casting technology (CASTRIP) recently again, directly continuous casting goes out the carbon steel steel band (UCS) of the about 0.7-2.0mm of thickness.For compound section, as H shaped steel base, I-shaped steel billet etc., more advanced technology is the casting for shaped blank continuous technology at present, because crystallizer is fixed, poring rate is low, can not satisfy continuous casting and continuous rolling integration production.
The tradition crystallizer all comes with some shortcomings in various degree, and has following shortcoming: (1) pulling rate is slower, and maximum pulling rate has only 3～6m/min, and is far apart with mill milling speed, can not realize continuous casting and rolling.(2) there be negative the slip in crystallizer and strand, are not synchronized with the movement, and casting billet surface produces oscillation mark, and surface quality is poor.(3) the crystallizer inhomogeneous cooling is even, easily causes the slab quality defective.(4) the water jacket cooling effectiveness is low, the device structure complexity, and cooling capacity is poor, and water consumption is big.(5) it is simple to produce section, and complicated, near-net-shape section can not be produced.(6) equipment complexity, investment is big.
Summary of the invention
It is a kind of arc formula crystallizer that is synchronized with the movement that the utility model purpose provides, and it can high-speed production near-net-shape compound section continuous casting billet, to be applicable to the production line of continuous casting and rolling.
The purpose of this utility model is achieved in that crystallizer internal cavity is to be closed by the chain relative group (button) that two of inner arc and outer arcs have a half of base type to form, article two, chain all is to be connected to form loop chain by crystallization shell joint, respectively by actuator drives, and can be synchronized with the movement with continuous casting billet.Section in the relative combination with the outer arc chain of inner arc chain is provided with the arcuate guide slide rail, with limit the inner arc chain running route, reach and determine that the movement locus of continuous casting billet in crystallizer is circular-arc.The outside at the outer arc chain is strained by straining pulley, so that its relative crystallization wall and inner arc chain crystallization wall in conjunction with section with the inner arc chain fits together, can hold the crystallizer internal cavity of continuous casting billet with formation.
This crystallizer adopts the mode of spray cooling, promptly is provided with water injector around section that inner arc and two chains of outer arc are interlocked.The pressure water spray directly impacts crystallizer copper wall inboard, and is bigger by about 30% than the crystallizer heat-transfer capability of the water jacket type of cooling, and water consumption can be saved 20% water than water jacket crystallizer, and designs simplification, and equipment is simple.
The utility model comprises two chains that respectively have half of base type groove, and two chains drive by transmission mechanism, are provided with the camber directive slide track in the inboard of inner arc chain, and the outer arc chain is outwards strained by straining pulley, is provided with water injector at two chains in conjunction with section.The crystallizer copper wall of inner arc chain and outer arc chain all has half of nearly end form groove, makes inner arc chain relative with the outer arc chain group (button) close the back crystallizer internal cavity that forms and can be arbitrary shapes such as H type, circle, square billet, rectangle.The crystallization shell of inner arc chain and outer arc chain joint with base shell direct contact surface (crystallization wall) be copper alloy, with the raising heat transfer efficiency.The transmission mechanism of inner arc chain and every chain of outer arc chain is at least two drives.
There is not sliding friction in the utility model because do not have relative motion between crystallizer wall and the base shell, can realize the compound section high speed casting, and casting rate can reach 10-120m/min, and as-cast structure is good, segregation-free, and surface quality is good.Because this crystallizer can improve pulling rate effectively, is convenient to be complementary with the milling train of follow-up rolling process, can realize the short flow process production of continuous casting and continuous rolling integration.This crystallizer is the mode that adopts the spray cooling, and the cooling effectiveness height can significantly reduce the slab quality defective, and cooling is even, and water jacket cooling water amount is little relatively.This crystallizer can be widely used in the production of the strand of various sections, and equipment is simple, invests little.
