Graphite Crucibles are refractory containers specially shaped for metallurgical operations. These are made of a mixture of Graphite, Refractory Clay, Grog and other additives. These crucibles are termed as clay bonded Graphite crucibles according to the raw materials used. The crucibles are available with or without spout. These crucibles are used for melting ferrous, non-ferrous metals alloys and noble metals.

Market Potential

The main market for the product is foundry industry. With the growing industrial sector the need for specialized metal and alloy castings is increasing day-by-day. With the advent of many multinational automobile industrial units, many auto spare are manufactured in large numbers in Haryana, Delhi, Punjab and Maharashtra States. There is a good demand in these States for graphite crucibles. As per an assessment 8.5% growth in foundry and Casting Industry is estimated in the country. The use of Graphite Crucibles shall accordingly increase. There is a good scope of development of modern smallscale industries with the growing prospects of special casting metallurgical industry both for domestic and export market.

Basis and Presumptions

  • The envisaged production capacity is based on single shift basis on 300 working days in a year.
  • The unit will purchase the technology from National Metallurgical Laboratory, Jamshedpur which have developed improved technologies for Graphite Crucibles.
  • The costs given are based on the current market rates and may vary from time to time.
  • The wages are as per the prevailing norms.

Technical Aspects

Process of Manufacture

The manufacturing process of the products is based on the improved technology developed by National Metallurgical Laboratory, Jamshedpur. The raw materials such as graphite, Refractory/plastic clay, grog and other additives are mixed in a pan mixer after taking proper batch proportions. The wet mass is then kept for ageing. The aged mix is then extruded in a de-airing pugmill and blanks are made. The crucibles are prepared from the blanks either by pressing in a hydraulic press or by jiggering. The shaped crucibles are then dried, glazed and fired in a kiln to develop strength and glaze.
