This improves accuracy of the forging and can in extreme cases reduce post forging machining allowances and have a positive effect on die life. [ 7 ] No harmful byproducts – Induction heating does not generate any environmental waste products and is a clean process as opposed to more traditional heating methods that generate smoke and toxic ...
Induction heating improves energy efficiency for injection and extrusion processes. Heat is directly generated in the barrel of the machine, reducing warm-up time and energy consumption. The induction coil can be placed outside thermal insulation, so it operates at low temperatures and has a long life. The frequency used ranges from 30 kHz down ...
The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting. Most modern foundries use this type of furnace, and many iron foundries are replacing cupola furnaces with induction furnaces to melt cast iron, as the former emit much dust and other pollutants ...
Electrotherm has built a mini steel plant of 0.70 million TPA capacity. The plant consists of sponge iron kilns, induction melting furnaces, rolling mills, and a 30MW captive power plant. The plant also utilises LRF technology allowing it to produce low sulphur, low phosphorus steel grades for forging applications.
Heat treating furnace at 1,800 °F (980 °C) Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.
Induction heating is a non contact heating process which uses the principle of electromagnetic induction to produce heat inside the surface layer of a work-piece. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I 2 R losses in the material.
In practice materials are usually heated to the upper limit first to keep forming forces as low as possible and to maximize the amount of time available to hot work the workpiece. [ 1 ] The most important aspect of any hot working process is controlling the temperature of the workpiece. 90% of the energy imparted into the workpiece is converted ...
Most induction heating devices (with induction frequency control) have a frequency range of 100 kHz to 200 kHz. The output range typically incorporates 2.5 kW to 40 kW. Induction heaters in this range are used for smaller components and applications such as induction hardening an engine valve. [5] MF induction generators work from 1 kHz to 10 ...
