退火炉温控系统改进１９９１年我厂新进一台池炉，其中玻壳退火炉设计是采用目前玻璃行业常采用的燃烧室及烟道中的热烟气，经碳化硅板幅射按升温（一区）、保温（二区）、降温（三区）三阶段工艺完成退火。各区温控由仪表定值控制。但由于玻壳进炉温度、数量和网带速度的... Annealing furnace temperature control system improvements In 1991, I plant a new pool furnace, glass furnace annealing furnace design is the use of the glass industry often used in the combustion chamber and the flue gas in the flue gas, by the silicon carbide panels by heating ( A district), insulation (two districts), cooling (three districts) to complete the three-stage annealing process. The temperature control by the instrument set value control. However, due to the temperature of the glass into the furnace, the number and speed ...
