Abstract
The utility model relates to a graphite die for a continuous up-casting crystallizer. The graphite die comprises a graphite die body (1), wherein a graphite die cap (2) is arranged at the bottom of the graphite die body (1), eight first through holes (3) are uniformly formed in the top of the graphite die cap (2) along the peripheral direction, and four second through holes (4) are uniformly formed in each side surface of the graphite die cap (2). The graphite die for the continuous up-casting crystallizer has the advantages that the agitation of a solution entering the graphite die is increased, the opportunity that furnace slags, charcoal and air bubbles enter the graphite die is reduced, and the impurity mixing, hollowness, uneven ingredients and loose texture problems of continuous up-casting are well solved.
Description
Technical field
The utility model relates to a kind of crystallizer used for up-drawing continuous casting graphite mo(u)ld.
Background technology
Because continuous up-casting is produced, the cost of the former base of wire rod is low, energy resource consumption is few and efficiency is high, on continuous up-casting, produce the former base technique of wire rod and obtained application widely, but the former base composition of wire rod that continuous up-casting is produced not is very even, and often there is folder ash, hollow phenomenon, serious impact the stability of producing and the quality of product.Upper while drawing the more active alloy of melting nature of production, due to the react slag that generate of melting raw material with furnace lining, slag may form the defect being mingled with in drawing process upper; In order to draw the generation of alloy solution inspiratory phenomenon in fusion process on preventing, be everlasting melt solution surface coverage charcoal and graphite flake, this also may cause the defect being mingled with.In continuous up-casting production process, owing to filling type deficiency, cause drawing rod of metal alloy surface and occur crescent shape defect; In continuous up-casting production process, intentionally electric furnace adopts the method for electromagnetic induction to stir conventionally, but, at the position far away apart from channel, particularly, draw graphite mo(u)ld position, stirring action a little less than, this just easily causes melt solution composition uneven, alloy molten solution starts the meeting of crystallization position and graphite mo(u)ld tip position because the phenomenon of component segregation appears in nonequilibrium freezing, causes properties of product and technologic unstable.
The method of using is at present: on conventional graphite mould, add filter cap, this filter cap is to be provided with a plurality of holes in its side, prevents the inclusion defect of bulk charcoal.But the continuous up-casting rod of metal alloy that the method is produced also there will be less inclusion defect, the problem of bubble, uneven components, mold-filling capacity deficiency and tissue looseness can not effectively be improved in addition.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the graphite mo(u)ld that provides a kind of upward continuous casting crystallizer to use, it has increased the stirring that enters graphite mo(u)ld solution, reduced the chance that slag, charcoal, bubble enter graphite mo(u)ld, well solved that continuous up-casting is mingled with, hollow, composition is uneven, the problem of tissue looseness.
The purpose of this utility model is achieved in that the graphite mo(u)ld that a kind of upward continuous casting crystallizer is used, it comprises graphite mo(u)ld, described graphite mo(u)ld bottom is provided with graphite mo(u)ld cap, described graphite mo(u)ld crown portion is along the circumferential direction evenly distributed with eight the first through holes, and described graphite mo(u)ld cap side is evenly distributed with four the second through holes.By the hole of the top at graphite mo(u)ld cap and the less and more different directions of side opening diameter, rely on many and little hole to guarantee to enter solution pure of graphite mo(u)ld, on reducing, draw the phenomenon that rod of metal alloy is mingled with as far as possible; The mobile stirring action that enters the melt solution of graphite mo(u)ld by different directions is tried one's best evenly the composition that draws rod of metal alloy, can also impel the gas in melt solution to overflow from the hole at top, reduces inspiratory phenomenon; The melt solution entering from top, under atmospheric effect, does not have the impact of self gravitation, can enter more rapidly band cap graphite mo(u)ld, can reduce the loose situation of casting bar.
Compared with prior art, the utlity model has following beneficial effect:
The graphite mo(u)ld that a kind of upward continuous casting crystallizer of the utility model is used, it has increased the stirring that enters graphite mo(u)ld solution, reduced the chance that slag, charcoal, bubble enter graphite mo(u)ld, well solved that continuous up-casting is mingled with, hollow, composition is uneven, the problem of tissue looseness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the graphite mo(u)ld used of a kind of upward continuous casting crystallizer of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Wherein:
Graphite mo(u)ld 1
Graphite mo(u)ld cap 2
The first through hole 3
The second through hole 4.
The specific embodiment
Referring to Fig. 1, Fig. 2, the graphite mo(u)ld that a kind of upward continuous casting crystallizer of the utility model is used, it comprises graphite mo(u)ld 1, described graphite mo(u)ld 1 bottom is provided with graphite mo(u)ld cap 2, described graphite mo(u)ld cap 2 tops are along the circumferential direction evenly distributed with eight the first through holes 3, and described graphite mo(u)ld cap 2 sides are evenly distributed with four the second through holes 4.
During use, graphite mo(u)ld cap 2 is installed on to the bottom of graphite mo(u)ld 1, then is arranged on crystallizer, then crystallizer is installed on upper leading mechanism bearing, in startup, draw; During continuous up-casting rod of metal alloy, the rod of metal alloy that approaches crystallizer secondary cooling copper tube is cooled and solidified first, being pulled mechanism moves up, in graphite mo(u)ld, form vacuum zone, under atmospheric effect, make melt solution enter graphite mo(u)ld cap 1 from top first through hole 3 of graphite mo(u)ld cap and the second through hole 4 of side, different directions and inhomogeneous flow velocity have aggravated the stirring to solution, and the composition that makes melt solution is overflowing of even aggravation bubble more all; The gravity that need not overcome self of the melt solution that the first through hole 3 by graphite mo(u)ld top enters, flow velocity is larger, can reduce casting alloy bar open texture and fill the situation of type deficiency; A plurality of minor diameter the first through holes 3 and the second through hole 4 guarantee to be mingled with that to enter the chance of graphite mo(u)ld less.
