The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated with big section round mold continuous casting of the present utility model.
As shown in Figure 1, continuous casting of the present utility model includes the water tank 1 that the inboard is lined with copper pipe, the sufficient roller support 7 of penetrating source capsule 2 and being connected with water tank with big section round mold structure, be provided with in water tank 1 upper outside and penetrate source capsule 2, utilize the end face of flange and the set bolt of water tank 1 and penetrate the end face of flange and the hole of source capsule 2, two end face of flange are close to, and meanwhile the set bolt cap also plays positioning action.Be provided with shower water water supply component 3 in water tank 1 inboard, make water tank 1 bottom intact, do not leak outside and to say around its bottom.Be provided with a plurality of rectangular grooves in the outside of water tank 1 bottom, be connected with sufficient roller support 7 by T type bolt 4, one end of T type bolt 4 is set in the groove of water tank 1 bottom, it can't be rotated, its other end passes the upper junction plate of sufficient roller support 7, this connected mode was both firmly simple and direct, had avoided the sealing problem of water tank 1 again.
The copper pipe 5 of described water tank 1 liner is the core component of this crystallizer, draws the success or not of steel billet, and cc billet surface quality and crystallizer life-span, copper pipe 5 is most important.Therefore, copper pipe 5 is designed to length 700-1000mm, and tapering is 0.05-.0.76mm, and copper pipe 5 taperings are according to the difference of drawing steel billet, and it is multi-form to can be single tapering, many taperings or the continuous tapering of parabola.
The water pipe 6 of sufficient roller support 7 is provided with the shower that multilayer has water nozzle.Be set to four layers of shower on the water pipe 6 of the sufficient roller support 7 of present embodiment, the angle of per two shower water nozzles is 60 ° of angles.Such structure strengthens injection flow rate, has guaranteed the supply of cooling water, with contact area and the uniformity to steel billet, has realized needs and rigidity when steel billet passes through to greatest extent.
Continuous casting of the present utility model is to realize like this with big section round mold.
As shown in Figure 1, 2, at first shorten water tank and enlarge the copper pipe tapering, the crystallizer of making because of the Circular measure that draws copper radius crystallizer self of 10.5m can't be put in the former vibration solenoid, dwindles external form so reduce water tank length, the box sizes up and down of water tank differs, and mutual dislocation, up-small and down-big, flange diameter is reduced, so resistance to compression strengthens, sealing improves, and effectively utilizes the space, has guaranteed output.
Enlarging the copper pipe tapering is the contact area that increases molten steel, also is to draw the needs of steel pricker degree to satisfy the needs of molten steel in copper pipe as far as possible.Because of copper pipe shortens, reduced the cooling of molten steel, steel billet has just gone out copper pipe so promptly increases output, and to guarantee the intensity and the thickness of steel billet shell, last lower box dislocation is to make it to put into solenoid in order to reduce external form, adapts with former design space.
Change into the external supply channel built-in.Be provided with shower water water supply component 3 around its bottom in water tank 1 inboard, because of the outer water supply of crystallizer has increased external form, change into built-in after, can cooperate with platform space, and reduce dismounting and maintenance from now on.
The built-in source capsule 2 of penetrating is changed into external, be arranged at water tank 1 upper outside, in water tank 1, cause the crystallizer external form too big, and the gland diameter causes the pressure testing distortion to leak too greatly because of penetrating source capsule 2.So consider to change external into, effectively utilized space outerpace, solved key problem in technology.
Former crystallizer is following sufficient roller support 7 to be connected by top flange by four pull bars, both takes up room, makes trouble, easily leaks again, maintenance difficulty is big.The utility model changes in the outside of water tank 1 bottom and is provided with a plurality of rectangular grooves after above-mentioned pull bar is removed, and is connected with sufficient roller support 7 by T type bolt 4, has avoided the appearance of the problems referred to above.
Adopt copper pipe 5 manufacturing process of round mold, silver-bearing copper or phosphorized copper Huo Chrome zirconium copper are extruded into pipe, carry out annealing in process, after the annealing pipe is pressed the crystallizer copper pipe that becomes greater than φ 350mm, after machined and coating processing, just finished product, copper pipe 5 cross dimensions are more than or equal to φ 350mm, crystallizer cooling water seam is formed by stainless steel water jacket and crystallizer copper pipe, the taper design of crystallizer copper pipe 5 is the continuous tapering of parabola, surface of internal cavity adopts Cr coating or composite deposite, adopts the crystallizer of this spline structure, and its steel transportation amount and disposable service life can significantly improve.
Continuous casting is as follows with the concrete parameter of big section round mold:
Crystallizer copper pipe section: φ 408mm
Crystallizer copper length of tube: 780mm
Crystallizer copper thickness of pipe wall: 17.93mm
Crystallizer copper pipe tapering: 4.68mm
