Heat treatment can be carried out by using gas burners. Either the piece to be heat treated will be insulated so it functions as its own oven, or pieces can be heat treated in a standing furnace. Gas burners can also be used to “dry out” or harden work pieces where refractory materials have been applied.
Gas burners provide the following benefits:
Heat treatment processes can be carried out using oil burners. The piece can be heat treated by insulation it so it functions as its own furnace, or pieces can be heat treated in a standing furnace. It is possible to perform a “dry out “or a hardening process which can be carried out on work pieces where refractory materials has been applied.
Heat treatment using induction has proven to be an powerful technology and very efficient in terms of power consumption. Materials are heated rapidly and uniformly from the inside. Any desired temperature can be achieved up till 760 °C.
By using water cooled induction cables this method of heating is user friendly. When installing for preheat application of large diameter or heavy wall thickness, costs can be reduced, since this method requires only one cable to be installed.
This method is not applicable to non-metallic materials. It is possible to rent or purchase our induction heat treatment equipment.
In most cases heat treatment is applied to steel and refractory materials in stationary furnaces. These furnaces can be either electrically or gas fired.
Through the use of insulated panels we can build a temporary furnace on location in a short period of time while providing a variety of possible dimensions. We can carry out heat treatment processes up till and including 650°C, ideal for the prefabrication of pipe work.
A temporary furnace enables the heat treatment of objects to large or complex to transport, these furnaces can be either gas or oil fired.
Resistance heating elements have proven effective for preheating and post weld heat treating welded connections and constructions. Flexible ceramic heating elements can be used on all types of metal.
The ceramic resistance elements used for this are available in various sizes and voltages.
The heat transfer is by means of heat radiation and direct contact. Using this method any desired temperature up till and including 1200° can be achieved in a controlled manner.
Resistance elements are also available for rent and sale.
