Abstract

The utility model discloses a disposable refractory preformed mould. The inner part of an outer mould is provided with an inner mould matched with the outer mould; the inner mould is provided with a reinforced groove; the inner mould is made of a low melting polystyrene board, so that the inner mould can sufficiently volatilize and melt in the roasting or burning process of refractory preformed component; consequently, the utility model can be simply and conveniently manufactured into the preformed component which is hollow and is provided with hollow reinforced pull bricks; the demoulding operation is convenient and time saving.

Description

Disposable fireproof prefabricated mould

The utility model relates to a kind of mould, especially a kind of disposable fireproof prefabricated mould.

Mould in fireproof prefabricated is the vitals in the forming technology, traditional mould and inner membrance are generally made by steel, wood, paraffin wax, gypsum etc., Cheng Mugao, loaded down with trivial details when pollution, the demoulding are arranged in the use, and the time is long, especially in prefabricated component manufacturing process, then be can't the demoulding to some Idiotype goods, though can make (as in the middle of some manufacturing process of fireproof prefabricated) in the practical application by assembling die, can not satisfy requirement of strength to some goods; In utility model patent 992011175 " the integral prefabricated quirk wall of open type calcining carbon " in used fireproof prefabricated the manufacturing process, its quirk wall Idiotype prefabricated component hollow, and inner width has only 242mm, and be distributed with strengthen and the baffling effect draw brick, by the man large and medium-sized enterprises of number the manufacture craft of mould was designed and made once, all because of quirk wall prefabricated component Idiotype complexity, can't the demoulding come to an end.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, forms applicable to the mould of various Idiotype goods, thereby solved a difficult problem that exists in the existing hollow refractory concrete prefabricated component manufacturing process.

The purpose of this utility model is achieved in that it mainly contains outer mold and inner mold, wherein is provided with the XPS inner mold in adventitia tool inside, is provided with strengthening groove on inner mold.

The utlity model has following advantage:

Simple in structure, cost is low, economy is convenient, the especially damage of having saved demould time and prefabricated component having been caused because of the demoulding with fireproof prefabricated of this Mold Making.It has overcome loaded down with trivial details in the existing manufacturing process, time-consuming, the shortcoming that the Idiotype prefabricated component can't the one piece demoulding.It is to synthesize (being that low-firing forms pore) with employing plastics microballon in developing lightweight " mullite brick " project, reaches lightweight (1.0kg/cm ³), design on the basis of the effect of high-strength (withstand voltage 30mPa), high temperature resistant (using under 1450 ℃ of flame temperatures).

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1;

Fig. 4 is the C-C cutaway view of Fig. 1;

Fig. 5 is the structure cutaway view of the utility model unfired;

Fig. 6 is the embodiment that the utility model is applied to 32 Room electrode baking quirk walls.

1. outer molds among the figure; 2. strengthening groove; 3. inner mold.

Be that example illustrates using method of the present utility model to manufacture the whole quirk wall of hollow type prefabricated component below, at first outer mold 1 is put well, populated within it refractory concrete material, and in outer mold 1, put into by hanging down the inner mold 3 that the fusibleness XPS is made, put in the strengthening groove 2 on inner mold 3 and draw brick or concrete material, behind the prefabricated section castable, toast or fire, volatile XPS as inner mold 3 in baking or sintering procedure volatilizees along with the rising of temperature, fusing, thus make prefabricated hollow belt draw the whole quirk wall prefabricated component Integratively of brick to be shaped and very convenient demoulding; The whole quirk wall of this kind prefabricated component monolithic molding, the intensity height, simple for production, easy to usely can be applicable on carbon anode roasting furnace W type and the V-type stove (see figure 6) on the (see figure 1) and 32 Room electrode bakings, be better than other fireproof prefabricated, the outer mold of disposable fireproof prefabricated mould of the present utility model can be recycled, and can design various inner molds as required, and it can also make the various concrete walls that have hollow; The Idiotype concrete product.

Claims

1, a kind of disposable fireproof prefabricated mould is characterized in that: be provided with XPS inner mold (3) in outer mold (1) inside, offer strengthening groove (2) on inner mold (3).
