Produce the alpha-beta corundum lip tile of sun power figured glass melting furnaces
Technical field:
The utility model belongs to special glass kiln technical field of refractory materials, mainly proposes a kind of alpha-beta corundum lip tile of producing sun power figured glass melting furnaces.
Background technology:
Chute is the key position that connects glass melter and forming room, mainly comprises chute brick and lip tile.In the melting furnaces of producing the sun power figured glass, lip tile is last piece refractory materials that glass metal flows through, and is connected into the type stack it under, is positioned to roll lower roll one side, and the position is special, so the quality of the structure of lip tile, brick is very important.
Summary of the invention:
The purpose of this utility model is to propose a kind of alpha-beta corundum lip tile of producing sun power figured glass melting furnaces; Make its structure can better protect the moulding stack of rolling press, prolong the work-ing life of rolling press, stack.
The technical scheme that its invention task of finishing the utility model is adopted is:
A kind of alpha-beta corundum lip tile of producing sun power figured glass melting furnaces, the upper surface of described lip tile is smooth, bright and clean plane; Described lip tile has the arc outer side that coincide with moulding calendering lower roll, makes the glass metal contact calendering lower roll of trying one's best few, can well protect the calendering lower roll; The intermediate location of the upper surface of lip tile and arc outer side is the arc outer, and is when making glass metal flow to forming press-roller, smooth and easy, can not form defective; Described lip tile has the draw-in groove of brick and chute brick at the bottom of the chute that is used for fixing the lip tile front.
A kind of alpha-beta corundum lip tile of producing sun power figured glass melting furnaces that the utility model proposes, its reasonable in design can better be protected the moulding stack of rolling press, prolongs the work-ing life of rolling press, stack, can combine with the chute brick is good simultaneously.
Description of drawings:
Accompanying drawing 1 is a cross-sectional shape synoptic diagram of the present utility model.
Among the figure: 1, upper surface, 2, the arc outer, 3, the arc outer side, 4, draw-in groove.
Embodiment:
The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, the upper surface 1 of lip tile is smooth, bright and clean plane, and the glass metal resistance to flow is little, pollution-free, do not foam; Described lip tile has arc outer side 3, coincide with moulding calendering lower roll, makes the glass metal contact calendering lower roll of trying one's best few, can well protect the calendering lower roll; The upper surface 1 of lip tile is the arc outer 2 of smooth smoothness with the intermediate location of arc outer side 3, and is when making glass metal flow to forming press-roller, smooth and easy, can not form defective; Described lip tile has a draw-in groove 4, is used for fixing brick and chute brick at the bottom of the chute of lip tile front.
Described lip tile adopts raw materials such as aluminum oxide powder, meticulous quartz sand, Wingdale, soda ash, makes through technologies such as high temperature melting, casting, annealing; The utility model only relates to the structure of lip tile, does not relate to preparation technology, and it is not done too much explanation.
