For more than 200 years our partner Parkinson-Spencer Refractories Ltd. (PSR) manufactures refractories. The experience of all these years can also be seen in the manufacturing of channel block up to a width of 60″ (1524 mm).
PSR channel blocks show a high resistance against corrosion and even after years appear in very good shape.
PSR uses PSR-333 material. In the future also the high quality material PSR-993 will be used for channel blocks.
On high precision machines the blocks get their final size. Before delivery every channel is preassembled and all dimensions are checked.
