Product Details

Due to their maximum temperature of 1650 °C and their large furnace chamber, the high-temperature bottom loading furnaces are perfectly suited for sintering translucent zirconia. The motor-driven lifting table significantly simplifies the charging of the high-temperature furnace. The all-around heating of the cylindrical furnace chamber ensures a very even temperature uniformity. The high-temperature bottom loading furnaces are additionally equipped with a drying as well as a forced cooling function. For residual drying, the oven remains open gapwise during heating up to a defined temperature and thus ensures reliable removal of moisture. For accelerated cooling, the furnace is automatically opened step by step under program control. Depending on the batch used and the saggars, these high-temperature furnaces can achieve total cycle times of less than two and a half hours. The furnaces can be individually programmed for all recommended sintering curves of all zirconia manufacturers.
