Topic: Insulation Compound– A global environment-friendly solution to reduce emissions from Iron and Steel Industries

Abstract: The insulation compound is an innovative product which traps and reduces the graphite flake emissions from liquid hot metal and reduces the skull generation in main runner and in ladles. The product is an iron based compound, which, when it comes in contact with the hot metal, generates a protective slag layer. It is added in front of the tap hole, just as the metal hits the main runner. Instantaneously, the protective layer of slag forms and metal gets a slag coating. The fumes and graphite particles released from the liquid metal junction is suppressed in the slag. When the normal slag flow starts, our slag flows along with it. Since the slag covering sticks to the liquid surface, it covers the hot metal surface even when the ladle is tilted for pouring purposes, allowing no scope for graphite emissions into the atmosphere.
