Description of Coil Grout Refractory
This product is used for coil (circulating water pipe, coil) and high temperature zone filling on various electric furnaces. The requirements of working environment for fire resistance, construction performance, insulation, thermal conductivity, high temperature strength, etc. are fully considered in the initial designing. It is a new type of high quality casting material in foundry industry. This product belongs to corundum matrix, with highest instant temperature of fire resistance up to 1700 ºC. It can effectively prevent and protect the coil from damage caused by furnace lining, and ensure personnel safety. The coil grout has been widely recognized by our customers, more than 95% of whom find it satisfactory.
Features of Coil Grout
>It can fix the coil and prevent deformation very well.
>It could effectively prevent the leakage of molten metal, protect the coil from damage and ensure personnel safety.
>It can buffer the expansion of furnace lining and prevent coil vibration.
> The coil shall be effectively protected from damage when the furnace is dismantled.
>The grout will prevent the coil turn from short circuit or excessive impulse current generated from discharge, which is energy-saving and protective.
> It is featured with simple construction, long service life and high-cost performance.
>Construction method: Plastering.
Construction and Heating Instructions
Mix water and the grout till it is applicable. The plaster thickness depends on the furnace size.
Packaging Standards and Storage Methods
> Imported new kraft paper with moisture-proof
> Leaking proof package, 25kg / bag, can be packaged as per the user's requirements.
> Stored in a dry place away from moisture. One year shelf life.
