Cast Iron Rolls Dealers in Gandhinagar

Rolls are tailormade products and therefore need careful production planning. Rolls are cast in chiller mould with a controlled allowance for contraction and machining. It is therefore necessary to have a mould of the desired size. A new mould is required to be made if oue is not available. After obtaining a order from a customer and a drawing for the reequired rolls, a method drawing for casting is made, according to which the mould for casting of the rolls is made. Melting of metal is carried out in any of the several induction melting units available as per requirement of metels. The melting charges are selected as per required chemistry of metal. Upon melting, samples are analyzed and necessary adjustments for various alloying elements made through additions of Ferro-alloys. Fracture tests are made and temperature measured to control the same through Immersion Pyrometeres. Metal is poured in the moulds through geared ladles of various capacities in pre-determined time to ensure clean metal in the mould.
