Description
The present invention relates to the ceramic kiln equipment technical field, particularly a kind of development that is mainly used in ceramic new product and existing ceramic product filled a prescription and the test furnace for ceramic products of technological innovation test.
Existing furnace equipment as the ceramic new product of test has three kinds: the one, and tunnel cave comprises roller kilns, pushed bat kiln etc., the 2nd, periodic kiln, the 3rd, resistance furnace.
Technical process can be divided into preheating zone, clinkering zone, salband (comprise quench zone, chilling after atmosphere processing section and slow cooling section) in the kiln of tunnel cave.The induced-draft fan that is loaded on kiln hood is evacuated to the preheating zone with the high-temperature flue gas that clinkering zone produces, and ceramic is progressively heated, and is drained by induced-draft fan through the flue gas of heat exchange.Clinkering zone is the place that fuel combustion produces high-temperature flue gas, also is that ceramic produces glassy phase, reaches densification and sinters the place of ceramic product into.Quench zone is that the chilling blower fan is directly sent into chilling wind and sprayed to ceramic product in the kiln, and ceramic product is reduced to rapidly about 700 ℃ from firing temperature.The slow cooling section is to take out behind the slow cooling section and drain by taking out the hot blast of air-heater after with chilling.The slow cooling section has cold wind that air blast sends into and the hot blast behind the chilling together ceramic product to be cooled off slowly, is cooled to 80-100 ℃ of left and right sides kiln discharge.In whole process of production, tunnel cave is actionless, and ceramic transmission mechanism in kiln transports down and is preheating to the Low fire ceramic product to the cooling kiln discharge from kiln hood, finishes the whole physical chemistry change procedure that burns till.Because in heating and the sintering process, it requires the interior section temperature difference of kiln can not be too big, and the rate of temperature fall of intensification, slow cooling section can not be too big, so the length of tunnel cave is all in 50-110 rice scope.Firing period was at 30 minutes to 20 hours.At present, during with tunnel cave trial-production new product, be to treat with 1 or several that test product is clipped in the product of positive large-scale production to carry out.Because it can only burn till under the calcining system of original product, thereby, can not test out best calcining system and new process for calcining, so.Its limitation is very big.
