Abstract
The utility model relates to a retractable crystallizer for electroslag casting. The retractable crystallizer is characterized in that the retractable crystallizer is composed of an upper crystallizer, a middle crystallizer and a lower crystallizer, wherein the crystallizer in the middle is in inclined plane contact with the upper crystallizer and the lower crystallizer; the outer side of the middle crystallizer is provided with a spring pressure device. When a casting is cooled and shrunk, the crystallizer in the middle is extruded out, and thus, the casing can not be blocked to cool or shrink; accordingly, cracks can not be formed on the casting, and the crystallizer can not deform.
Description
Technical field:
The utility model belongs to casting technology field, and particularly a kind of electroslag smelting casting is with making a concession crystallizer.
Background technology:
Electroslag smelting casting is the special casting method that integrates refining of metal and casting, adopt the electroslag smelting casting method can the organization of production densification, dimensional accuracy height, premium casting that non-metallic inclusion is few.
It is no deformability that electroslag smelting casting is adopted copper or steel design, its disadvantage usually with crystallizer (sand mold that is equivalent to conventional cast).When molten cast shape intricate casting, often shrink foundry goods is cracked because of crystallizer hinders foundry goods.For example: when certain multidiameter foundry goods, molten according to a conventional method casting,, hindered the cooling of multidiameter and shunk, caused multidiameter by drawing crack or crystallizer II gross distortion because of crystallizer II does not have deformability (seeing shown in Figure 1).This problem does not still have solution preferably at present both at home and abroad.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind ofly guarantees electroslag smelting casting that foundry goods cooling shrinks with making a concession crystallizer, foundry goods is not cracked and crystallizer does not deform yet.
The purpose of this utility model is achieved in that it is made of three crystallizers in upper, middle and lower, wherein in the middle of crystallizer with up and down between two crystallizers the inclined-plane contact, be provided with spring attachment outside the crystallizer in centre.
For crystallizer in the middle of guaranteeing can be extruded when the foundry goods cooling is shunk smoothly, a middle crystallizer and inclined-plane contact angle a should be greater than material friction from the locking angle between two crystallizers up and down, i.e. tga＞f, f is a contact-making surface sliding friction coefficient.
The utility model has the advantages that not hindering foundry goods cooling shrinks, thereby foundry goods is not cracked and crystallizer does not deform yet.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Fig. 1 is former ordinary mould structural representation;
Fig. 2 is that this crystallizer is made a concession the pre-structure schematic diagram;
Fig. 3 is that this crystallizer is made a concession the back structural representation.
The specific embodiment:
By accompanying drawing as can be known, this crystallizer is made of three crystallizers in upper, middle and lower 3,2,1, wherein in the middle of crystallizer 2 with up and down between two crystallizers 3,1 inclined-plane contact, its inclined-plane contact angle a should be greater than material friction from the locking angle, be tga＞f, f is a contact-making surface sliding friction coefficient.A crystallizer 2 is extruded in the middle of when the foundry goods cooling is shunk, and the crystallizer height reduces, and forms and makes a concession distance h.In order to maintain the crystallizer reset condition and steady when making a concession, be provided with spring attachment 4 in middle crystallizer 2 outsides.
Claims (2)
1, a kind of electroslag smelting casting is characterized in that with making a concession crystallizer: it is made of three crystallizers in upper, middle and lower, wherein in the middle of crystallizer with up and down between two crystallizers the inclined-plane contact, be provided with spring attachment outside the crystallizer in centre.
2, electroslag smelting casting as claimed in claim 1 is characterized in that with making a concession crystallizer: a middle crystallizer and inclined-plane contact angle a should be greater than material friction from the locking angle between two crystallizers up and down, i.e. and tga＞f, f is a contact-making surface sliding friction coefficient.
