Microcrystalline glass production line

The utility model discloses a microcrystalline glass production line, the two working roll sets up side by side on its calender, and the working roll is followed the axial and is the linear shrinkage form from the middle part to both ends, and the calender 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. Thereby, reduced follow -up flattening polishing treatment's work load, also saved raw and other materials, reduced manufacturing cost. The cooling annealing section of crystallization annealing stove installs the conveyer pipe additional, and cooling blower blows a cold wind over to micro -crystal glass plate through the conveyer pipe to reduced micro -crystal glass plate's cool time, promoted the crystallization quality, also compressed the length of cooling annealing section, makeed the length of cooling annealing section only be 2/5ths of crystallization annealing stove total length, thereby reduced microcrystalline glass production line's cost and manufacturing cost.
