Description
Technical field
The present invention relates to a kind of methods for preventing platinum channel ontology deformation, and in particular to prevents in liquid crystal substrate glass manufacture
The only method of platinum channel agitator upper flange deformation.
Background technique
In liquid crystal substrate glass semi-finished product production technology, platinum channel is to be clarified glass metal, be homogenized and cooled down
Important workshop section.Platinum channel is setting for the technique section being connected between the Muffle furnace of the kiln and formed glass plate that melt glass
It is standby, it is defeated after the responsible glass metal progress high temperature clarification after melting rich in bubble for sending kiln, homogenizing, stirring, cooling
Give molding section.Platinum channel heats glass metal using a variety of Electric heatings.According to big classification, platinum channel
Electric heating be divided into and directly heating and indirect heating two major classes.Directly heat is to lead to the alternating current after transformer pressure-reducing
The method crossing " L " type copper bar and being flexible coupling on the ring flange for access platinum channel to be heated to platinum channel ontology.Indirectly
Heating then by peripheral heating element heats, is transferred to the method that platinum channel ontology is heated by thermal insulation material.Usually
The indirect heating material used has Si-Mo rod, Elema or platinum wire (patent document 1).And agitator is pair in platinum channel
The important mechanism that is homogenized of glass metal after tank furnace melts guarantees the temperature of agitator and takes into account the fortune of stirring rod in production
Row need to place a pair of of cover board, for keeping the temperature on the flange on agitator top.But when being heated up by starting, agitator itself expansion,
And flange is influenced by copper bar, and expansion or swell increment can not be followed inadequate, so that along higher than Flange Plane, cover board on agitator
Brick easily occurs tilting to two sides when placing, and causes gap between front arch larger, heat insulation effect is very bad, front arch top
Temperature it is relatively low, agitator top volatile matter abnormal increase, volatile matter falls generation defect, influences the stability of producing line.
It is abnormal when causing front arch to place platinum channel agitator upper flange deformation in production, caused cover board temperature
Relatively low, the normal electric current for passing through the heat preservation for increasing cover board top and promoting cover board is spent, to promote the temperature of cover board, but promotion effect has
Limit, and the normal gradient that will cause agitator space temperature is broken, and causes platinum volatilization serious, in base plate glass platinum defect compared with
It is more, cause product because content discard it is more.Simultaneously because cover board places exception, cover board temperature is low, caused volatile matter growth
Comparatively fast, volatile matter is easily fallen in operation, leads to the excitation of air blister defect, causes the fluctuation of production.
