Description

A kind of graphite jig of horizontal casting method crystallizer

Technical field

This utility model is related to a kind of mould, and in particular to process for oxygen-free copper stripe in a kind of horizontal casting method crystallizer Graphite jig.

Background technology

Horizontal casting method produces oxygen-free copper stripe, is that cathode copper Jing power frequency induction furnaces are fused into liquid, and warm stove is by copper Liquid temp is controlled in prescribed limit, after copper liquid enters graphite jig, by the traction of horizontal casting traction machine in a crystallizer Quick crystallisation by cooling, so that continuously produce oxygen-free copper belt blank.

Crystallizer plays vital effect during horizontal casting method production copper strip billet, and wherein graphite jig is made It is the part with copper strips directly contact, its architectural characteristic directly affects the performance of copper strips.

Utility model content

Utility model purpose：In order to solve the deficiencies in the prior art, this utility model is tied there is provided a kind of horizontal casting method The graphite jig of brilliant device, can carry out effectively sizing while the friction between copper strip billet and mould can be effectively reduced to copper strips Power, not only ensure that the performance of copper strip billet, also extend the mold use life-span.

The purpose of this utility model realized by such technical scheme, a kind of graphite of horizontal casting method crystallizer Mould, including mold and lower mould, the mold is rectangular structure, and the mold and lower mould with lower mould On be equipped with through hole of the plural number through top and bottom, the screw hole of the upper lower water jacket of the through hole and crystallizer is corresponded, described Mold upper surface is being just cancave cambered surface to body of heater porch, and its radian is 0.05 °, and the lower mould upper surface two ends are provided with side Bar, is cancave cambered surface on the inside of edge strip, and radian is 60 °, thickness of the edge strip thickness by drawing copper strip billet, and between the edge strip of two ends, distance is institute Draw the width of copper strip billet.

The edge strip thickness is 17mm, and width is 30mm.

Die size is 510*490*28mm, and case hardness is 650-760HV, and surface-brightening no marking can Jing after polishing Reuse 3 times, polishing thickness is 3mm every time.

The thick graphite papers of one layer of 1mm are covered with the lower surface of the mold upper surface and lower mould, it is ensured that upper mould It is brought into close contact between tool and upper water sleeve, lower mould and lower water jacket.

Compared with prior art, a kind of graphite jig of the horizontal casting method crystallizer disclosed in this utility model, passes through The strake control of lower both mold ends is cast the thickness of copper strips, is 0.05 ° by the upper surface of mold just to body of heater porch radian, Friction of the copper strip billet between graphite jig can effectively be reduced, it is ensured that the performance of copper strip billet, while reduce friction can improve The mold use life-span；The outside of upper/lower die covers one layer of graphite paper, after some solution mould installions between upper lower water jacket Causing mold breakdown because there is gap, equally extending the mold use life-span.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme of this utility model embodiment is carried out clear, complete Description.

As shown in figure 1, a kind of graphite jig of the horizontal casting method crystallizer disclosed in this utility model, including mutually lid The mold 1 and lower mould 2 of conjunction, wherein mold 1 are rectangular structure, with the plural through hole 3 through top and bottom, and should Through hole 3 is corresponded with the screw hole on the upper water sleeve of crystallizer, and the upper surface of the mold 1 is recessed just to body of heater porch Cambered surface, its radian are 0.05 °, can effectively reduce the friction between copper strip billet and graphite jig, and the lower mould 2 is in cuboid Structure, the screw hole on its same plural through hole 3 having through top and bottom, and the lower water jacket of the through hole 3 and crystallizer is one by one Correspondence, the two ends of 2 upper surface of lower mould have shelves bar 4, and the thickness of its grade of bar 4 is 17mm, and width is 30mm, and on the inside of which Cambered surface of the face longitudinal direction in 60 ° of indent, thickness of the edge strip thickness by drawing copper strip billet, between the edge strip of two ends, distance is by drawing copper The width of made-up belt.

The thick graphite papers of one layer of 1mm are covered with the lower surface of the upper surface of the mold and lower mould, it is ensured that on It is brought into close contact between mould and upper water sleeve, lower mould and lower water jacket.

A kind of graphite jig of the horizontal casting method crystallizer disclosed in this utility model, its assembly method is：

The surface of the lower water jacket and upper water sleeve of crystallizer is carried out into grinding process, it is ensured that its levelness；

Graphite jig is arranged on cooling jacket by torque spanner, it is 2N/m control torque magnitude, and graphite jig The graphite paper of one layer of 1mm of pad between cooling jacket；

The integral installation that graphite jig is formed with cooling jacket adjusts levelness with parallels in crystallizer shell, then The shell of crystallizer is tightened with torque spanner, torque magnitude is controlled for 160N/m；

Finally will be filled up at cooling jacket and crystallizer housing slot with fire clay.

Technology contents of the present utility model and technical characteristic have revealed that as above, but those of ordinary skill in the art still may be used A variety of replacements and modification without departing substantially from this utility model spirit can be made based on announcement of the present utility model, therefore, this practicality is new Type protection domain should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model and repairing Decorations, and covered by present patent application claim.
