Crystallization kiln and annealing kiln are combined together by the present invention, are combined into one, compared to two independent kilns, total length
Short, making is low with the cost of installation, and fixed assets investment is few.
The present invention comes out from a upper procedure, not heated above and below initial segment, roller in cooling area, product
And cooling device, product Temperature fall, eliminate the stress in product；In back segment, product sets cold close to coring area, roller top
But device, roller lower section set heater, and heating and the amplitude cooled down are all smaller, slow transition.
The present invention sets heater below coring area, roller, cooling device is set above roller, by from top to bottom
Slowly, uniform thermograde change, makes interiors of products structure regularly be nucleated, increase.Especially at the horizontal edge of product
Region, under the influence of thermograde, interiors of products structure nucleation rule and the region internal structure nucleation rule in the middle part of product
It is identical, the excessive stresses in product transverse direction will not be caused.
The present invention is provided with heater above and below heating zone, roller, by same above and below roller
Shi Jiare, product are rapidly heated, and are rapidly achieved the temperature range of crystallization.
The present invention is in crystallization region, and after being rapidly heated of heating zone, product is in suitable crystallization temperature scope, roller
Top sets cooling device, and lower section sets heater, is changed by slow, uniform thermograde from top to bottom, makes product
