A circular kiln is an industrial furnace, wh ere products are heated on a rotary hearth.
Circular kilns are mainly used for heating blanks during tube rolling, wheels, and the kiln tyres of the rolling stock for thermal treatment of metal products as well as for heating non-ferrous blanks prior to rolling.
A circular kiln consists of a rotary hearth and an arched immobile ring-shaped channel. The blanks are positioned on a flat hearth by using pits. These places concentrate thermomechanical stress resulting in destruction of the pits and uneven heating of blanks. Therefore, all used materials shall have considerable abrasion resistance and small-case thermal expansion.
Our lining systems guarantee quick and easy installation, good heat insulation, and overall savings on power costs. The wide range of heat insulation materials allows us to perform successful repairs on circular kilns.
The furnace flat hearth lining is multi-layered:
Finished products can be manufactured for the kiln working layer lining.
The furnace wall lining is multi-layered:
The furnace roof lining is multi-layered:
The lining of the gas duct, recuperator, and chimney stack are made of various lightweight gunned castables, as well as insulation fire-clay grog concretes.
