Abstract
Метод за термична обработка на стъкло, съгласно който стъклото се нагрява до температура над неговата точка на омекване и се спуска и потапя в флуидизиран дребнозърнест материал, характеризиращ се с твоа, че стъклото се потапя в газофлуидизирания слой от дребнозърнест материал, имащ определена температура и едрина на зърната, като материалът преди потапянето се намира в спокойно, равномерно разширено състояние на флуидизация на частиците му. Устройство за осъществяване на метода, състоящо се от вертикална нагревателна пещ под която е разположена камера за огъване с матрици, а под неярезервоар за дребнозърнест материал за охлаждане, характеризиращо се с твоа, че към дъното на резервоара е закрепена чрез болтове микропореста мембрана, разположена между резервоара и газонагнетателната камера. Патентните претенции са формулирани в 13 точки.A method of heat treating glass, according to which the glass is heated to a temperature above its softening point and lowered and immersed in a fluidized fine-grained material, characterized in that the glass is immersed in the gas-fluidized bed of fine-grained material having a certain temperature and size of the grains, the material being in a relaxed, uniformly expanded state of fluidization of its particles prior to immersion. Apparatus for carrying out the method, consisting of a vertical heating furnace under which a die-bending chamber is located, and below it a reservoir for fine-grained material for cooling, characterized in that a microporous membrane is bolted to the bottom of the reservoir, located between the tank and the gas compression chamber. The patent claims are formulated in 13 points.
