Abstract
The utility model discloses a composite casting type heat-resisting sliding block casting die which comprises a die body. A working block forming cavity and a base forming cavity are formed in the die body, the working block forming cavity is formed over the base forming cavity and is communicated with the base forming cavity, the working block forming cavity is communicated with a heat-resisting alloy pouring channel with an opening in the die body, and the base forming cavity is communicated with a common metal pouring channel with an opening in the die body. The composite casting type heat-resisting sliding block casting die has the advantages of being simple in structure, convenient to maintain, strong in heat exchange capability and capable of saving energy and reducing consumption.
Description
Technical field
The utility model relates to the casting device of pusher-type furnace heat temperature resisting sliding lumps, relates in particular to a kind of composite casting formula heat temperature resisting sliding lumps casting mould.
Background technology
Heating furnace is operation in advance important in hot rolling technology, and steel billet is heated to the rolling of coming out of the stove after uniform temperature in stove.Pusher-type furnace skid is comprised of floor tube and heat temperature resisting sliding lumps.The operation block of heat temperature resisting sliding lumps directly contacts with heating steel billet, is bearing very high temperature, therefore to the high-temperature capability of the material of heat temperature resisting sliding lumps operation block, requires very high; And the base of heat temperature resisting sliding lumps contacts with floor tube, temperature is lower, adopts general material just can satisfy the demands.Conventional heat temperature resisting sliding lumps structure has two kinds: a kind of is the heat temperature resisting sliding lumps that adopts common monoblock type casting, and a kind of is the inserted type heat temperature resisting sliding lumps that upper and lower sub-base combination forms.Because heating resisting metal is expensive, therefore adopt common cast-in-block heat temperature resisting sliding lumps cost very high.And for inserted type heat temperature resisting sliding lumps, the easily generation relative motion when tapping due to operation block and base, can cause the mutual wearing and tearing between operation block and base, reduction of service life; Also easily there is the phenomenon that operation block comes off when moving with steel billet from base, cause between steel billet lower surface and base and bump, make steel billet scratch on the bottom surface, have a strong impact on plate quality, even cause the generation of security incident simultaneously.
Summary of the invention
In order to solve the high or awkward technical problem of the existing cost of existing conventional heat temperature resisting sliding lumps, it is a kind of simple in structure that the utility model provides, the composite casting formula heat temperature resisting sliding lumps casting mould that heat temperature resisting sliding lumps cost is low, serviceability is good, safe to use, the life-span is long of casting.
The utility model is achieved by the following technical solution: a kind of composite casting formula heat temperature resisting sliding lumps casting mould, comprise die main body, it is characterized in that: in described die main body, have operation block forming cavity and base forming cavity, described operation block forming cavity be arranged at base forming cavity directly over and operation block forming cavity be connected with base forming cavity, described operation block forming cavity is communicated with the heat-resisting alloy cast passage that is provided with opening on die main body, and described base forming cavity is communicated with the common metal cast passage that is provided with opening on die main body.
Described heat-resisting alloy cast passage connects the cavity wall bottom of operation block forming cavity.
Described common metal cast passage connects the cavity wall bottom of base forming cavity.
Between described operation block forming cavity and base forming cavity, be provided with catch.
Described catch is continuous swallow-tail form.
The heat temperature resisting sliding lumps of casting by a kind of composite casting formula of the utility model heat temperature resisting sliding lumps casting mould, heat temperature resisting sliding lumps base adopts lower-cost ordinary steel, operation block adopts the heating resisting metal heat-resisting, anti-wear performance is excellent, adopts the mode of composite casting, realizes metallurgical binding between the two.
The heat temperature resisting sliding lumps of casting by the utility model is compared with the slide block of traditional integral casting, when reducing the use of precious metal, reducing production costs, also has good serviceability.
The heat temperature resisting sliding lumps of casting by the utility model is compared with inserted type heat temperature resisting sliding lumps, and owing to having realized metallurgical binding between operation block and base, its bond strength, far above mechanical bond, has cost low, safe to use, the feature that the life-span is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model catch.
Sequence number in figure: 1, die main body; 2, operation block forming cavity; 3, base forming cavity; 4, heat-resisting alloy cast passage; 5, common metal cast passage; 6, catch.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, a kind of composite casting formula heat temperature resisting sliding lumps casting mould, comprise die main body 1, in described die main body 1, have operation block forming cavity 2 and base forming cavity 3, described operation block forming cavity 2 be arranged at base forming cavity 3 directly over and operation block forming cavity 2 be connected with base forming cavity 3, described operation block forming cavity 2 is communicated with the heat-resisting alloy cast passage 4 that is provided with opening on die main body 1, and described base forming cavity 3 is communicated with the common metal cast passage 5 that is provided with opening on die main body 1; Described heat-resisting alloy cast passage 4 connects the cavity wall bottom of operation block forming cavity 2; Described common metal cast passage 5 connects the cavity wall bottom of base forming cavity 3; Between described operation block forming cavity 2 and base forming cavity 3, be provided with continuous swallow-tail form catch 6.
When using the utility model casting heat-resistant slide block, according to the thickness of the required swallow-tail form catch of calculation of parameter such as casting rate, die cavity base portion volume, sprue volume and melt temperature, to guarantee that catch can keep its physical form before melt is full of die cavity base portion, then base and operation block junction in mould form, insert swallow-tail form catch, to the common molten steel of the inner casting of base die cavity, in base die cavity be full of molten metal time, to the heat-resisting molten steel of the inner casting of operation block die cavity.Because swallow-tail form catch melts under the effect of molten metal high temperature, therefore can realize the metallurgical binding of base and operation block.
Base material selection Cr25Ni20 alloy in the present embodiment, operation block material selection Co50 alloy, during concrete casting, first adopt Cr25Ni20 alloy designs and make swallow-tail form catch, and swallow-tail form catch is inserted to precalculated position, secondly the melted Cr25Ni20 alloy of difference, Co50 alloy, casting Cr25Ni20 alloy melt, when Cr25Ni20 alloy melt is full of die cavity base portion, with being about to Co50 alloy melt, pour into die cavity operation block part, obtain required heat temperature resisting sliding lumps.Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model, above scheme being done that does not depart from technical solutions of the utility model, within all still belonging to the utility model protection domain.
