High-tech and quality

The production of fused cast refractory blocks is carried out under strict technological control.* Initially, the batch of the high purity well controlled raw and auxiliary materials is fused in an electric arc furnace. The fused material is oxidized and cast into moulds to form the precise shape of the final blocks.

Controlled annealing is carried out after the removal of the moulds. After cleaning and machining the blocks are individually checked and pre-assembled. The assembled furnaces or parts of furnaces may be checked by the customers’ inspectors, at this stage. After quality control the blocks are marked and packed for dispatch according to the destination of the goods and the mode of transport to be used.

To assist the proper installation of the blocks assembly drawings and photographs are made of the pre-
assembly and are provided to the customers.
