Description
Technical field:
The present invention relates to a kind of refractory for continuous casting production method, particularly a kind of Submersed nozzle of sheet billet production method.
Background technology:
In the submersed nozzle production process, a most important link is moulding, and mould generally according to the rim of a bowl position down during moulding; The hole method up that spues designs; Adopt its rim of a bowl of the mouth of a river that this kind method produces and discharge opening position to be mostly circle or square (the rim of a bowl ratio spue position, hole a lot of greatly), size is bigger, and moulding is easy; The demoulding is simple, and is not fragile.But special-shaped submersed nozzle particularly sheet billet is compared widely differently with traditional submersed nozzle with its shape of submersed nozzle, shown in Figure 2 like Fig. 1, its rim of a bowl position b is circular, and is small-sized; And position, the hole a that spues is a flat, and is complex-shaped, and size is big; According to traditional submersed nozzle die design method designing mould, flat body region a very easily causes its face pressurized effect bad, after the brick moulding like this; This face brick body is thin, does not reach required size, and uneven thickness when adopting the moulding of traditional moulds method for designing; Change in size is big, is difficult to control, the most important thing is demoulding difficulty; Fragile, so qualification rate is very low in the molding procedure, has increased manufacturing cost greatly.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of Submersed nozzle of sheet billet production method, comprises the steps: (1), batching: raw material are prepared burden according to predetermined weight percent; (2), batch mixing, granulation: the material that the first step is prepared mixes, and adds bond, utilizes the comminutor grain, and the oven dry pellet makes it to satisfy condition of molding; (3), moulding: the second step gained pellet is added in the Submersed nozzle of sheet billet assembling die, and sealing is through isostatic pressing machine compression moulding; (4), dry, burn till: shaped article is carried out drying, and in kiln, burns till: (5), processing: the 4th step products obtained therefrom is carried out machined according to set dimensional requirement, obtain finished product by set temperature curve; Wherein the Submersed nozzle of sheet billet assembling die comprises base described in the 3rd step; Be fixed on core assembly and outer gum cover on the base; And the Jiao Gai that is used for sealing core assembly and outer gum cover; And also be provided with interior gum cover between said outer gum cover and the core assembly, gum cover fixed head in being provided with between said core assembly and the base.
The present invention's technical characterictic further is:
Also be provided with sealing ring between Jiao Gai and interior gum cover and the core assembly in the said Submersed nozzle of sheet billet assembling die.
Said Submersed nozzle of sheet billet assembling die China and foreign countries' gum cover and interior gum cover contact-making surface scribble lubricating oil.
Core assembly is connected with base through screws or bolt in the said Submersed nozzle of sheet billet assembling die.
The gum cover fixed head is fixedly connected with base with core assembly through screw or bolt in the said Submersed nozzle of sheet billet assembling die.
Base designs has the edge circle that is used for fixing outer gum cover in the said Submersed nozzle of sheet billet assembling die.
The invention has the beneficial effects as follows: the traditional relatively submersed nozzle of the present invention production method; Mould design at formative stage is equivalent to adopt the design of falling the demoulding mould; And owing between said Submersed nozzle of sheet billet assembling die China and foreign countries' gum cover and core assembly, be provided with interior gum cover, therefore when falling the demoulding can the protection tile body, and after the gum cover demoulding outside of interior gum cover; Can directly it vertically be cut open with instrument; Laterally peel this glue off and get final product, need not from bottom to top pull, avoided in pulling process, scratching the brick body.Therefore improve the moulding qualification rate, saved manufacturing cost.

Fig. 2 is the structure cutaway view on the apparent direction of a Submersed nozzle of sheet billet left side;
Fig. 3 is the structure cutaway view of medium thin slab submersed nozzle assembling die one embodiment of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation:
A kind of Submersed nozzle of sheet billet production method comprises the steps: (1), batching: raw material are prepared burden according to predetermined weight percent; (2), batch mixing, granulation: the material that the first step is prepared mixes, and adds bond, utilizes the comminutor grain, and the oven dry pellet makes it to satisfy condition of molding; (3), moulding: the second step gained pellet is added in the Submersed nozzle of sheet billet assembling die, and sealing is through isostatic pressing machine compression moulding; (4), dry, burn till: shaped article is carried out drying, and in kiln, burns till: (5), processing: the 4th step products obtained therefrom is carried out machined according to set dimensional requirement, obtain finished product by set temperature curve; Wherein Submersed nozzle of sheet billet assembling die (as shown in Figure 3) comprises base 7 described in the 3rd step; Be fixed on core assembly 3 and outer gum cover 5 on the base 7; And the glue lid 1 that is used for sealing core assembly 3 and outer gum cover 5; Gum cover 4 in also being provided with between wherein said outer gum cover 5 and the core assembly 3, gum cover fixed head 6 in being provided with between said core assembly 3 and the base 7.
In order to increase sealing effectiveness, prevent to get into water in the forming process, also be provided with sealing ring 2 between the lid 1 of glue described in the present embodiment and interior gum cover 4 and the core assembly 3.
For protection tile body better in the knockout course, said outer gum cover 5 scribbles lubricating oil with interior gum cover 4 contact-making surfaces.
Said in the present embodiment core assembly 3 is connected through screw or bolt with base 7.Gum cover fixed head 6 is fixedly connected with base 7 with core assembly 3 through screw or bolt in said.Said base 7 also is designed with the edge circle that is used for fixing outer gum cover.
The production method of the traditional relatively submersed nozzle of the present invention is equivalent to adopt the design of falling the demoulding mould in the design of the mould of formative stage, and gum cover is directly pressed brick shape and designed; Need not make the brick body in forming process, reach stressed even, the effect that the brick surface is smooth, attractive in appearance in two; And because gum cover 4 in said outside, being provided with between gum cover 5 and the core assembly 3, so in when falling the demoulding, can the protection tile body, and after interior gum cover 4 gum cover 5 demouldings outside; Can directly it vertically be cut open with instrument; Laterally peel this glue off and get final product, need not from bottom to top pull, avoided in pulling process, scratching the brick body.Therefore improve the moulding qualification rate, saved manufacturing cost.
Though the present invention has described the specific embodiment herein, coverage of the present invention is not limited thereto.On the contrary, all technical schemes in all scopes that drop on claim on literal or under the instruction in equivalents are in fact contained in the present invention, and protection scope of the present invention is as the criterion with claims.
