Silcarb offers energy efficient, low down time and easy to maintain silteck range of furnaces. These include electric furnaces for melting non-ferrous metals, high temperature furnaces for heat treatment, continuous annealing furnaces for wire annealing, stainless steel wire annealing, angle heating for bending of angles, and, zinc vaporization furnaces for zinc oxide production. The company has its own production plant for manufacture of silicon carbide heating elements which form the heart of the electric furnaces. These elements are more efficient compared to metallic coil type elements made out of nickel chrome. The elements are straight rods and hence can be repalced in 10 to 15 minutes. Therefore, there is no down time in the equipment. The furnaces are designed with a control transformer and a control panel, so that only the required energy would be fed to the furnace thereby resulting in better efficiency and more energy conservation. The range of furnaces produced is for melting copper alloys, aluminium, zinc and for melting and refining of gold and silver. Special furnaces are available for continuous annealing of stainless steel wires, capillary tubes, etc. Furnaces for melting gold and silver are available from 1 kg up to 50 2 kg capacity. These furnaces are much cheaper than induction furnaces and are the only alternative available for electric melting purposes. Small portable gold melting furnaces that operate from a 3 pin 15 amps plug are available, which can be used by jewellers in their shops, workshops or residences. Special furnaces for heating of angles and plates for bending purposes are also available where energy saving to the tune of 60% has been achieved. The company has also developed immersion-melting furnaces for galvanizing wires, capable of achieving energy efficiencies to the extent of 40% to 50% compared to the conventional furnaces now available. It has specialized in heating applications up to temperatures of 1450 oc with state-of-the-art designs and controls resulting in high-energy savings, ease of maintenance and complete reliability.
