Melting tank carries out, and clarification, the glass being homogenized enter material path through dog-hole, increased channel, and temperature is controlled at 1260 DEG C~1320 DEG C,
After material path cools down, calendaring molding (1150 DEG C~1250 DEG C of forming temperature) is carried out into calender.
Step 4: calendaring molding
Every production line uses two table glass calender (the using and the reserved) calendaring moldings, and plate thickness, width can be according to lifes
Production requires to be adjusted, and the communicated roller-way of glass tape of forming enters annealing kiln annealing.
Step 5: annealing
Glass tape enter annealing kiln temperature be 600 DEG C~720 DEG C, at 650 DEG C~700 DEG C keep the temperature 10~after twenty minutes, by 3
DEG C/minute~5 DEG C/minute of speed is cooled to 560 DEG C~600 DEG C, then it is cooled to 300 DEG C by 7 DEG C/minute~12 DEG C/minute of speed, then
40 DEG C of kiln discharges were cooled to by 40~60 minutes, subsequently into cold end cutting action.Cold end cutting action presses sets requirement or visitor
The length that family requires cuts glass tape, forms semi-finished product (annealed sheet) after cutting, is sent to crystallization kiln crystallization through transition roller table.
Step 6: crystallization
The qualified annealed sheet of detection enters crystallization kiln, and 630 DEG C~680 DEG C were warming up to through 60~80 minutes, 630 DEG C~
680 DEG C of heat preservations coring in 40~60 minutes, had been warming up to 800 DEG C~850 DEG C through 50~70 minutes, 30 is kept the temperature at 800 DEG C~850 DEG C
~80 minutes crystallization were cooled to 40 DEG C of kiln discharges through 80~120 minutes, complete crystallization process.As hair plates (crystallization plate), send to mill
Cut workshop finishing.
Step 7: grinding and polishing
Detection qualified crystallization plate such as is polished through ZDML-16 full-automatic mills, is polished at the surfaces processing, and then storage is protected
It deposits.
It should be further noted that after using composition of raw materials provided by the invention, finally to ensure in formula
Main component meet following table formula design：
Patent of the present invention takes whole crystallization to prepare devitrified glass technique, is mixed by raw material, and high temperature melting is rolled into
Shape, Annealing Crystallization complete the production process of product.For other jade products, devitrified glass jade product is in materialization spy
Property aspect, closer to natural jade.The present invention can be used for producing jade devitrified glass, and product 200~300MPa of compression strength resists
Curved 40~80MPa of intensity, 2.6~2.7g/cm of density3, 6~7 grades of Mohs' hardness, water absorption rate<0.01%, glossiness ＞ 98, it is resistance to
Acid is alkaline-resisting, and radiological measuring meets national A classes examination criteria.Suitable for ground, metope and table top decoration.Meanwhile devitrified glass
Jade product has acid-alkali-corrosive-resisting, and will never fade feature, this is also the advantage that other products cannot compare.In production process
By controlling granite dosage, changes the content of coloring iron ion, a variety of colour system jade devitrified glasses can be prepared.Work as Fe2O3
Mass fraction be less than 0.3% when, product in grease it is white, work as Fe2O3Mass fraction at 0.3% to 0.5%, product in breast
White, work as Fe2O3Mass fraction at 0.5% to 0.8%, product be in ecru.
