SILICON CARBIDE CRUCIBLES A crucible is a refractory container used for metal melting and its production which can withstand high temperatures required to melt the metal, without itself being melted.Our Crucibles are being manufactured with highly automated &efficient machineries with modern, advance technique under competent experienced expertise.
Salient Features
  • Resistance to Stress
  • Resistance to Oxidation
  • Resistance to Erosion
  • Resistance against Alkaline Chemical Attack
  • Superior Conductivity
  • Minimum Fuel Consumption
  • Minimum Metal Loss

Stopper heads are used for controlling outflow of molten metal through the nozzle of bottom pour ladles. It works from inside of the ladle to open and close the passage through the pouring nozzle which extends vertically through the bottom of the ladle and to control the flow of the molten metal.Our Graphite Shopper Heads can be used for laddle sizes of 500 Kg to 30 MT of liquid metal for which various sizes & quality combinations are available.
