Carbonaceous Additives

Product Details:

Based on European Seacoal, we had indigenously developed Lustrous S3. A carbonaceous additive having the swelling capacity. During pouring hot metal into the moulds, it heats lustrous S3 to swell making it to enter the pores between sand grains providing plasticized bonding so that the volume expansion of the sand grains, caused by structural transitions in Si0₂, can be accommodated without fracture of the cast face mould surface, thus reducing the chance of expansion defects also.

 

Advantages:

• Lustrous carbon that forms a thin film with high adhesion on sand grains

• It swells and clogs the intergrain spaces and compensation of thermal stress from micro dilatation of sand grains

• Physically expands itself to fill the spaces between the sand grains

• Item Code: Lustrous-S3

Product Details:

It is a synthetic substitute for coal dust in green sand system. It has consistently very low ash, high volatile matter, excellent flow ability. Lower ash & higher lustrous carbon content makes it possible to greatly reduce the percentage of new sand addition in the system sand. The required percentage addition depends on sand parameters, but typically 0.3 to 0.5%. Also the casting finish & peel are excellent, thus substantially reducing the shot blasting cycles.

Specs: VM : 74.0 to 78.0%, Ash : -3.5% max. FC: By difference

Advantages:

• Lower ash built up in the system sand 8c higher permeability

• Lower new sand additions reducing cost

• Adaptable to mechanized addition due to excellent flowability

• Lower moisture additions leading to lower pin holes/blow hole porosity in castings

• Excellent as cast finish 81 peel resulting in lower shot blasting costs
