High-Temperature Bogie Hearth Furnaces with SiC Rod Heating up to 1550 °C

Bogie hearth furnaces equipped with SiC rod heating can be used for the production of technical ceramics, especially for sintering at working temperatures up to 1550 °C. The bogie hearth furnaces from 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.
