CastCoat Mould Coating for the Continuous Casting Proces
Protect the heart of your Continuous Casting Machine with world leading technology. This hard composite coating was developed for, and has been used in, steel industry applications in particular for coating continuous Caster copper mould plates, for more than 20 years. Tests have shown that the coating is tougher than any other copper mould plate coating available. It has a low coefficient of friction which helps reduce sticker alarms and the coating is inert to liquid steel and casting powders. The coating system has no effect on mould level detectors or electromagnetic stirrers. It has also been proven that the coating has negligible effect on heat transfer rates.

With years of field data behind the coating, significant copper plate life improvements have been demonstrated: 3 – 4 times for thick slab casters and up to 6 times for thin slab caster narrow plates, accompanied by improved product shape. In operation, the coating has been shown to enable extended casting runs through dramatic increases in wear resistance. Eventual progressive degredation of the coating occurs due to the thermal fatigue in high stress positions. Now a mature technology with a worldwide customer base, CastCoat continues to provide users with reduced costs/tonne.
By coating all four faces of the mould, dimensional stability is retained throughout the campaign, leading to sustained and effective product shape and shell growth. The lack of appreciable wear means longer campaigns are possible between mould exchanges, achieving higher caster availability. In addition, the protection offered by the coating gives extended copper plate life, resulting in annual copper savings and delivering significant reductions in both on and off-line maintenance costs. With the recent development of a Compact HVOF device, the CastCoat Composite Coating can now be applied to tube moulds.

In the production and processing of steel, great demands are made on the surfaces of rolls, as they have a direct inuence on the quality of the product being manufactured. CastCoat is used to protect foot rolls and other mould components from high temperature wear.
