High-Temperature Bogie Hearth Furnaces with SiC Rod Heating up to 1550 °C
The furnace chamber is equipped with a high-quality insulation made of high-temperature fiber blocks.
Function and equipment
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 bogie hearth furnaces WHTC 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.
- Tmax 1550 °C
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
- Swing door hinged on the right side
- Heating from both sides via vertically mounted SiC rods
- Thyristor controllers with automatic output compensation counteract the aging of SiC rods
- Multi-layer insulation with high-quality fiber modules on the heating chamber side
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
