LHT 01/17 LB Speed

Due to its maximum temperature of 1650 °C and its large chamber, the LHT 01/17 LB Speed high-temperature bottom loading furnace is 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.

Equipped with special heating elements made of molybdenum disilicide, chemical interactions between the charge and the furnace components are almost avoided. The sintered material is placed in saggars made of technical ceramics. Up to two batch containers for max. 15 single crowns per level can be accommodated in the LHT 01/17 LB Speed.

The high-temperature bottom loading furnace is 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 furnace can achieve total cycle times of less than two and a half hours. It can be programmed for all recommended sintering curves of all zirconia manufacturers.
