Microcrystalline glass production line

The utility model discloses a microcrystalline glass production line, the upper work roll of its calender is linear shrinkage form from the middle part to both ends along the axial. The microcrystalline glass production line can effectively prevent because the feed says that there are one gradient difference in the temperature of both sides and the temperature at middle part when the calendering to and because the raw materials receives the influence in feed way walking orientation, and the thin both sides in the panel that leads to the fact middle part are thick, the roughness of panel has been guaranteed. Preceding half section of the cooling of crystallization annealing stove annealing section installs the conveyer pipe additional, and cooling blower blows a cold wind over to micro -crystal glass plate through the conveyer pipe, and pumping pipe is installed additional to the second half section of as -cold annealing section, pumps the fan and takes away through the waste heat of pumping pipe on with inside of boiler micro -crystal glass plate to through the exhaust chimney discharge, compressed the length of cooling off the annealing section, make the length of cooling off the section of annealing only be 2/5ths of crystallization annealing stove total length, thereby reduced microcrystalline glass production line's cost and manufacturing cost.
