CRUCIBLES

With our constant quest for excellence, we are able to set standards of performance and today, the first choice of the discerning, quality conscious foundry man is Greaves Morganite Silicon Carbide Crucibles.

Manufactured from carefully selected flake graphite and silicon carbide, bonded with resin, our crucibles offer the following specific advantages.

HIGH RESISTANCE TO THERMAL SHOCK  

In use, crucibles are often subjected to the stresses created by rapid and/or uneven changes of temperature, which in extreme cases can lead to premature failure. Outstanding resistance to thermal shock is imparted to our crucibles as the heat is distributed quickly throughout the crucible, by usage of selective grades of flake graphite and silicon carbide.

 
 
HIGH RESISTANCE TO EROSION  

The flow of molten metal and charging the crucible with solid metal leads to abrasion and erosion of the inside wall.  The high proportion of silicon carbide in our crucibles  imparts better strength, greater hardness and high resistance to erosion.
 

HIGH RESISTANCE  TO CHEMICAL ATTACK BY FLUXES AND SLAGS  

Though graphite is chemically inert and resistance to corrosive chemicals, the bond is often susceptible to chemical attack by fluxes and slags.
Our crucibles made of chemically inactive graphite, silicon carbide and carbon, resist attack by the alkaline fluxes used for light alloys; the oxidising/reducing fluxes used for copper alloys and the corrosive slags formed from them.

HIGH RESISTANCE TO ATMOSPHERIC OXIDATION  

Graphite oxidises progressively in air as the temperature is raised. Most crucibles have an external glaze to prevent this.  As no external glaze is perfect by itself, invariably oxidation of graphite occurs, leading to loss of thermal conductivity and reduction in strength of the crucible
  
To provide extra resistance to oxidation, we have protective agents incorporated in the body in addition to the external glaze.
  
CONSTANT MELTING SPEED  

The superior oxidation resistance of our crucibles ensures that they retain a constant melting speed to the end of their long life.

More heats per day means more output, but equally important is the consistency of output which enables the foundrymen to schedule their production more effectively.

FUEL ECONOMY  

The amount of fuel needed to melt, in an ordinary crucible increases steadily as the crucible oxidises and loses speed.  The consistent high melting speed of our crucibles makes for substantial fuel saving in comparison to other crucibles.

LOWER METAL LOSS

The amount of metal lost by oxidation during the melting process is proportional to the time taken to melt and cast the charge.
  
Our crucibles with their higher average melting speed reduce the overall melting time to a minimum and consequently make an essential contribution for reducing metal losses.

These important advantages of Morganite Crucible India Ltd. play their part in giving a longer life, greater output, lower fuel consumption and lower metal losses.

In short, Morganite Crucible India Ltd. offer foundry men lower production cost per ton of metal melted, a pre-requisite for a competitive advantage.

 

The Superior quality of Greaves Morganite Silicon Carbide Crucibles is achieved by the stringent quality tests conducted at our R & D Cell, equipped with the modern facilities of quality testing.

   

   
 

Greaves Morganite Silicon Carbide Crucibles are of superior quality  as they undergo the most stringent quality-control tests at our R & D Cell.

The manufacturing plant at Aurangabad has the most modern processing facilities, with state –of-the art technology based on environment-friendly resin bonding. And a quality system established as per international statndards with an
ISO 9002 certification.

 


   
    
 
Company Profile :
 
nite Crucible Ltd. was set up in 1986 in collaboration with Morganite Thermal Ceramics Ltd., U.K.., one of the largest manufacturers of crucibles in the world, to manufacture Resin Bonded Silicon Carbide Crucibles.

The manufacturing plant at Aurangabad is equipped with the most modern facilities of processing. That State-of-the-Art technology is based on evironment friendly resin bonding.

The trained, dedicated and spirited employees shape the superior quality and long life crucibles consistently. The quality system established in the plant is as per international standards and has ISO 9002 Certification to it's credit.

GMCL, Aurangabad in collaboration with Morgan Thermal Ceramics Ltd., U.K. are presently involved in expansion of present set up at Aurangabad and increasing the product ranges. They are introducing small size graphite crucibles and big size silicon carbide crucibles very soon.
