Step 2: being arranged and being formed with and pour type chamber according to the shape that is related to of forked type chute using template.In order to
It is enough that castable (corundum self-flowing material) is poured into mould inside, it offers on mold (being made of muti-piece template) by template splicing
It is being formed and have and pour mouth, and longitudinally fixed one piece of 6mm thickness in the big face of castable for what corundum self-flowing material was poured
Template, the purpose that template is arranged is dilatation joint after casting there are 5-7mm.
In one embodiment of the invention, template is preferably designed using wooden formwork structure, is existed to reduce castable
Water loss speed in casting process, the face that the present invention mutually splices two pieces of adjacent templates using smooth flat structure to
Realize the seamless connection between template.Meanwhile the medial surface of template being provided with pitch paint layer, it can be to mould by pitch paint layer
Plate is protected, and can reduce water loss.
Step 3: pouring corundum self-flowing material, it is dried after the molding of corundum self-flowing material.It limits herein: corundum self-flowing material
Water content be 7.5%-8.5%, it is preferred to use 8%.
Also, in step 3, corundum self-flowing material is closely knit using hand-rodding after casting process.
Specifically, in step 3, first with air-dried demoulding, 280-320 DEG C of height is used for the material after demoulding
Temperature is toasted, and baking time is 2.5-3.5 days.
In the present invention, above-mentioned processing step, using the selection of material and the improvement of structure can guarantee device
It is less prone to cracking, has the advantages that long service life.
The above is only a preferred embodiment of the present invention, is not intended to restrict the invention, and comes for those skilled in the art
It says, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any modification, equivalent
Replacement, improvement etc., should all be included in the protection scope of the present invention.
