Description
Technical field
The utility model relates to stove and accessory, particularly relates to a kind of glass tempering furnace.
Background technology
At present, the common ultra-thin glass that thickness is 1.8-2.2mm, intensity is very low, and in processing or handling process, as easy as rolling off a log generation is broken.People can only reduce the making area of glass, and to reduce the glass breaking probability, this just causes the scope of its use more narrow.Trace it to its cause, it is mainly the glass tempering furnace used now, only be suitable for processing the glass of 3-19mm thickness, produce with this annealing furnace the glass that thickness is 2mm and have following problem: the first, the planeness of glass does not reach the requirement of GB≤3 ‰, the especially large-area glass of 1.6-2.5 square metre.The second, the one side of glass contact live rollers, due to the distortion that glass produces in heat-processed, the local contact of glass roller-way overlong time, and produce fraying of surface, form white mist.Three, due to the inhomogeneous of heating with enhancement method is improper, make the glass surface Stress non-homogeneity after strengthening, be difficult for cutting again.
Produce the reason of these problems mainly: the first, have the type of heating of glass tempering furnace and the ultra-thin glass that control method is not suitable for 1.8-2.2mm thickness now.The radiation heating mode is mainly used in traditional heating, and glass enters in process furnace with normal temperature, and the bottom of glass is with radiation, transmits heat form acquisition heat; But some stoves do not have the top heat form; Some stoves are stove silk or radial lamella direct radiation glass.For the stove silk, change conveniently, radial lamella is divided into some unit by the stove silk, has larger gap between each radial lamella, can cause the radiation of glass inhomogeneous; And the temperature between each radial lamella is not transmitted.Glass is inhomogeneous owing to being heated, and can produce distortion, and the distortion of glass has just caused local and ceramic roller friction, and several local point of contact bear the weight of glass, thereby the part that has produced glass frays, and produces " white mist ", and larger distortion in addition.So mostly the thin glass of the processing of general annealing furnace, be the thin glass that thickness is 3-5mm, it is very large that " white mist " appears at thin probability on glass, and the ultra-thin glass that thickness is 1.8-2.2mm can't be processed at all in this stove.
The second, the convective heating on top arranges for eliminating " white mist ", but the employing of annealing furnace convection current now is pressurized air, and compressed-air actuated convection current is high pressure, few to flow point; Can cause between excessive, adjacent two gas orifices of convection current dot center pressure and the too small phenomenon of pressure between two row's convection tubess, can make thin glass heats initial deformation more serious, so that the glass of 1.8-2.2mm can't have been used.
Based on the problems referred to above, the simple glass annealing furnace is difficult to the ultra-thin glass of 1.8-2.2mm is carried out to efficient hardening, therefore, be badly in need of utility model and go out a kind of glass tempering furnace, effectively solve the problem of the glass of 1.8-2.2mm thickness being carried out to tempering, fill up the blank on technique, and this equipment still can be strengthened to the glass of general thickness.
