Description
Technical field
The present invention relates to a kind of control method of glass metal viscosity, particularly a kind of method by electrically heated material road quick adjustment glass metal viscosity.
Background technology
Material road is a production unit between frit smelting furnace and feeding machine.Its Main Function is that glass metal is delivered to feeding machine by material road stream.Glass metal flow through material road time, must constantly to glass metal carry out heating guarantee glass metal finally arrive feeding machine time, keep temperature required.Glass metal in material road is due to the difference of upper and lower temperature and affect due to the viscous force of glass metal with material road inner bottom part material contacting surface, easily causes glass metal expecting to occur obvious laminar flow phenomenon in road.The most obvious feature of this laminar flow phenomenon is: in material road, the temperature of middle part glass metal is high, flow velocity fast, and edge temperature is low, flow velocity is slow; Material road internal upper part temperature of glass liquid is high, flow velocity fast, and bottom glass liquid temp is low, flow velocity is slow.Under normal circumstances, the temperature level of glass metal often determines the viscosity size of glass metal, therefore, when expecting that the temperature of glass liquid in exit, road differs greatly, its viscosity differences is also comparatively large, and the form that the glass produced with this often has the existing supply channel of obvious laminated striation phenomenon many employings fuel oil or heated by gas is come to glass liquid heating, and thermo-efficiency is lower, and calorific loss is comparatively large, poor working environment.
Authorization Notice No. is that the Chinese patent of CN2050038 U devises a kind of globars that some amount is housed above the hopper of supply channel.Heat is then produced to globars energising radiation heating is carried out to the glass metal in material road.Material has four temperature controlled region in road, respectively temperature thermocouple is housed, temperature signal is passed to the temperature controller of each section, carry out the time of globars electrified regulation in this district of regulable control, ensures the temperature needed for glass.This type of heating thermosteresis is little, easy to operate, but still thermo-efficiency is not high, and the upper and lower non-uniform temperature in material road, can not regulate glass metal viscosity fast and effectively, cannot ensure the quality of glass wool.
Publication number is that the Chinese patent of CN 1566001A provides a kind of microwave heating supply channel and uses the glasswork manufacture method of this kind of supply channel, by the microwave that microwave generating apparatus produces, from top to down penetrate glass metal, make the uniformity of temperature profile of expecting glass metal horizontal direction and vertical direction in road, the temperature difference that each position goes out diminishes, solve gob weight weight to differ, the phenomenon that in feed, crystallization glass is piled up.But the power of microwave generating apparatus is less, be difficult to the high-power working condition adapting to factory, adding frit road internal operating temperature is all more than 1200 DEG C, and can volatilize a large amount of alkaline matters, cause Working environment to be alkaline atmosphere, so just make microwave generating apparatus in use be among the hot environment of alkalescence, very easily suffer damage, need often to change, cause production cost greatly to improve.
The mode that existing frit road only use only globars heating regulates material road inner glass fluid viscosity, the mode of such adjustment, due to the constructional feature of globars in material road and the problem of power parameter, make when adjustment, material road internal upper part glass metal can response regulation in advance, and the glass metal of bottom really needs the long period just can reach working temperature and the kinetic viscosity of our needs, need the longer time, efficiency is very low.In addition, such regulating measure can make to expect that road inner glass liquid upper temp is high, flow velocity fast, and bottom glass liquid temp is low, flow velocity slow, causes glass metal at material road congregate crystallization, formed at drain hole and be detained, affect normally carrying out of glassy product quality and production.
