Firstly, being matched according to the ratio of the castable for manufacturing burnt tank liner as described in any one of claims 1 to 5
Material；
In next step, after completing ingredient, by alumine, calcium hexaluminate, calcining quartz, forsterite, magnesium aluminate spinel, hydration oxygen
The material for changing aluminium, dextrin and water-reducing agent composition, which is put into blender, was mixed for the first predetermined time, also, by silester
It is uniformly mixed with the water of predetermined amount, then, the mixture of silester and water is stirred to the second pre- timing together with the material
Between；
In next step, after stirring for the second predetermined time, stirring material resulting after stirring is injected to the mold internal vibration fixed
Molding；
In next step, by blank of material moulding by casting resulting after vibration moulding, and the third predetermined time is conserved, then demoulding obtains
Lining model in burnt tank；
Finally, by lining model baking, heat preservation and natural cooling in burnt tank.
