High-Temperature Bogie Hearth Furnaces with SiC Rod Heating up to 1550 °C FURNA PECKA ZA VISOKA TEMPERATURA

Bogie hearth furnaces equipped with SiC rod heating can be used in the production of technical ceramics, especially for sintering at working temperatures up to 1550 °C. The WHTC product line with especially robust design can hold heavy charges including kiln furniture. The furnace chamber is equipped with a high-quality insulation made of high-temperature fiber blocks. The bogie insulation is structured in multi-layer lightweight refractory bricks on the heating chamber side.

The furnace is heated along both sides by vertically installed SiC heating rods. This heating technology permits processes requiring working temperatures above 1350 °C which cannot achieved with wire heating elements. The SiC rods are controlled by thyristor controller which counteract the aging of the heating elements by means of automatic power compensation.

Additional equipment The WHTC bogie hearth furnaces can be equipped with extensive additional equipment to be optimally adapted to individual processes.
