Description
Technical field
The invention belongs to the glass melting field, specially referring to a kind of is to prolong tank furnace work-ing life and reduce glass defect, and the glass melting furnace dog-hole is adopted forced cooling method air-cooled and that water-cooled combines.
Background technology
In the production of glasswork, in the manufacturing especially for kinescope glass shell glass, very tight to the specification of quality of glass.Guarantee the quality of product, the nucleus equipment of most critical is a glass melting furnace, and good glass metal cools off rapidly in order to make fusing clarification, blocks the immersion of not melting sand grains and scum silica frost on the liquid level, and regulates glass metal stream, provides high-quality, qualified glass metal to molding procedure.In the middle of melting pool and work pool, be provided with the separating device of glass metal, Here it is dog-hole.Dog-hole is to be built by laying bricks or stones and formed by the special refractory brick of a cover, is that a cross-sectional area between melting pool and the work pool is very little, but the culvert that is positioned at bottom, kiln pond that can be communicated with melting pool and work pool.The concrete effect of dog-hole is exactly that glass metal when melting pool is when flowing near the dog-hole, be subjected to stopping of fire bridge above the dog-hole, do not melt sand grains on the metal level and scum silica frost is stopped, can not enter normal production stream, the good glass metal that sinks to deep layer enters work pool by dog-hole to have only fusing.Its existence has stopped that advantageously scum silica frost, foam and the glass metal that fusing is not good enter work pool, has played the effect of selecting glass metal and cooling, and it is bad to have reduced glass effectively.
Dog-hole can also reduce the backflow that flows to melting pool from cooling end (work pool), has so correspondingly improved the thermo-efficiency of tank furnace, has reduced fuel consumption.But as the unique passage that connects melting pool and work pool, characteristics are: area is little, the glass metal flow is big, temperature is high, the refractory materials at this position is washed away, corrodes more serious.Because dog-hole is subjected to washing away of high temperature, big flow glass metal, corrode the most seriously, be the weakest position of tank furnace.In a complete set of dog-hole refractory brick, it is to be noted front arch especially, it below the front arch glass metal, brick, liquid exist bubble at the interface, formed a gas, liquid, solid three phase boundary, similar near the situation the glass line, thereby the undercutting process that occurred typically making progress (or title) vertically to pit shape erosion process, again because the flowing of glass metal, cause flowing of bubble, help leaving away of reactant (being the corrode thing) and entering of new glass liquid, thereby accelerated deteriorating of refractory brick.A hole is just deteriorated in alveolate place, therefore causes many pits on the surface of brick.And this phenomenon is big more with bubble, and is many more, flow is big more, temperature is high more, and the degree of deteriorating is just even more serious, causes the dog-hole front arch very easily to damage.
So in a furnace life, directly influence the work-ing life of tank furnace the working life of dog-hole.The erosion at this position, service condition directly have influence on the stable of glass quality, also are the key factors that restriction glass works productivity effect further improves.In known technology, just carry out artificial air blast cooling at the flow liquid hole, to reduce the wear and tear speed of dog-hole position refractory brick, and we are in actual production, how to prolong the work-ing life of tank furnace dog-hole, reducing the frequency of maintenance of dog-hole, make the work-ing life of dog-hole consistent with the glass melting furnace bulk life time, is the target that the glass manufacturing is being sought always, explored.
Summary of the invention
The technical issues that need to address of the present invention are to need method of cooling preferably at dog-hole in the glass melting furnace, only take simply air-cooledly in the past, and poor effect in order to improve this weak point, is prolonged the work-ing life of dog-hole and whole glass melting furnace.The objective of the invention is to, a kind of effective method of cooling is provided, the glass melting furnace dog-hole is forced cooling, this purpose is finished by the following technical solutions, a kind of glass melting furnace dog-hole forced cooling method, it is characterized in that, the glass melting furnace dog-hole is adopted pressure cooling air-cooled and that water-cooled combines simultaneously, outer surface at the dog-hole front arch, be close to the brick face water cooling coil pipe is set, be provided with the air blast cooling pipeline simultaneously, the hot resistance that the thermometric degree is used be installed at dog-hole front arch place, and on instrument direct displays temperature.Described pressure air-cooled and that water-cooled combines is cooled off, and its air-cooled pipeline pressure is greater than barometric point, and the temperature of water coolant is 18-22 ℃ of scope.The resistance wire that described thermometric degree is used is directly to be close to refractory materials to install, and is convenient to the temperature variation of digital monitoring dog-hole refractory materials.By two kinds of coolings of air-cooled and water-cooled way of combining that people ignored, the key position in restriction glass melting furnace life-span is forced cooling before adopting in the method, prolonged the tank furnace life-span effectively, improved glass quality.And in implementation process, the cooling effect of dog-hole will suitably be grasped, lower the temperature that glass metal can solidify hardening in the hole when excessive, make to produce to be subjected to very big influence.Cooling is not enough, not only causes the wasting of resources, and makes refractory corrosion serious, and it is stable to influence tank furnace life-span and glass quality, and therefore needing will have monitoring exactly to the temperature at refractory materials place.We have implemented reasonable cooling through after fully proving to dog-hole, and from present method of cooling and service condition, effect is remarkable, especially reaches the tank furnace in later stage for the life-span, has slowed down erosive velocity effectively, has reduced the glass fraction defective.Be the operating temperature of direct viewing dog-hole refractory materials simultaneously, at this position hot resistance be installed, so that the digital monitoring temperature variation.Beneficial effect of the present invention is, after adopting water-cooled and air-cooled two kinds of types of cooling to dog-hole front arch and the enforcement cooling of contact surface place, effectively reduce the temperature at contact surface position, reduce herein glass metal by a relatively large margin to the erosive velocity of refractory materials, prolong the life-span of tank furnace dog-hole and even whole tank furnace, reduce because the various glass defects that erosion action causes.
