2.2%, ripe magnesium soil: 8.1%, clay: 8.3%, spodumene: 7.8%；
Making step is:
Hard Red Stone Ware, high-al clay, potassium feldspar, soft Red Stone Ware, magnesium soil, clay, spodumene are entered into ball mill processing respectively,
250 mesh 10000-hole sieves are ground to full by drying is spare, finally carries out ingredient by formula ratio again and enters mill progress fine grinding, fineness 250
Mesh 10000-hole sieve full by, add water that mud is made, then with mud press the mud made be pressed into moisture content be 21% mud cake, it is aging
After 7 days, with vacuum deairing machine white silk 2 times or more, purple clay section is obtained；
By purple clay section by mechanism roll forming, drain casting, high pressure solid casting and cold moudling, moulded pottery not yet put in a kiln to bake is made, makes
Through repaired biscuit after moulded pottery not yet put in a kiln to bake drying out, purple casserole base is obtained；Then it is kept the temperature under the conditions of 120 DEG C for 24 hours, at 1260 DEG C -1280 DEG C
Under the conditions of fire 6h-8h, blowing out keeps the temperature 30 minutes, and heat-proof purple sand casserole is made in cooled to room temperature.
The ingredient of purple clay section are as follows: SiO2: 64%, Al2O3: 23%, Fe2O3: 6.58%, MgO:3%, CaO:1.6%,
Li2O:1%, K2O:0.31, TiO2: 0.5%, NaO:0.02%.
Beneficial effects of the present invention:
Raw material sources are extensive, low in cost, and good product quality is at low cost, high efficiency, heat-proof purple sand casserole of the invention, product
Thermostabilization is good, is heated to 460 DEG C and is put into the exchange of 20 degree of cold water not burst three times, and it is vertical to be placed on the inside by good heat conductivity for napkin paper
I.e. catching fire is on fire, high mechanical strength.The chemical composition range of purple clay section product: SiO2: 64%, Al2O3: 23%,
