Electric furnace (kiln) – 1300°C


This electric furnace is developed on request of customer involved into production of ceramic grinding stone products.

Furnace description:

Due to very long heat-treatment cycles furnace is built with dual door, dual trolley system which allows unloading and loading of one trolley while second is inside furnace. Trolley transport is manual, this is enabled by design of wheels which allows easy one-man loading and unloading of very heavy trolley while completely loaded. All electric equipment is factory prepared for fast and easy connecting on site.

Furnace construction:

This furnace is built with standard building system for 1300°C but it is specific due to fact it was delivered to Kenya where customer did positioning and commissioning by itself or via remote supervision(remote programming of control system).
Furnace is built in dry assembly system with multi insulation materials which allows optimal furnace weight and insulation characteristics while having internal walls which are highly resistant thermally and mechanically.

Dry assembly system allows high vibration resistance during transport of finished furnace and easy service of insulation material.

Heating elements:

Heaters are mounted on ceramic supports which are supported by specially formed mounting bricks. Heaters are made in-house from high quality Kanthal material. Due to proper sizing of heaters their useful life is very long.

Temperature regulation:

Temperature is regulated with three regulation zones via temperature regulators realized within Siemens PLC. Complete control system can be remotely accessed for purposes of diagnostics or reprogramming of control/supervision system .


Operating conditions:

This furnace, as are other ovens and furnaces of our production, is built for industrial usage in harshest condition, and in practically non-stop operation.
