Carbon is one of the most versatile materials available for hot-metal applications.Both amorphous and graphitic forms of carbon remain stable under reducing conditions to temperatures well above 5000 F.In oxidizing atmospheres, the rate of oxidation is slow enough to allow the use of this extremely refractory material in "sacrificial" coatings that are conveniently reapplied as needed.It is difficult to wet most carbon based coatings with metal and slag. Therefore TOP’s carbon and graphite products are good candidates for coatings that are used at or below the liquid metal line or on troughs or other foundry equipment used to convey liquid metal. In this way, carbon-based foundry coatings and washes are used to protect expensive refractory linings, soluble metal troughs, and other costly foundry equipment from the highly erosive effect of liquid metal and corrosive slag. By spending a few pennies on a sacrificial carbon-based coating, the foundry can save many equipment.
