Energy-saving Induction Heating Furnace

Equipment purpose

◆ heating before forging: used for heating before forging of gear, ring gear, half shaft connecting rod, bearing, shackle, rigging and other products;
◆ online heating: pipeline anti-corrosion spraying, blue brittle blanking of bar stock, online tempering of steel (wire) pipe, etc.
◆ local heating: bending of U-bolt, thermal assembly of drum, bending of steel pipe and other production heating processes

Performance features

◆ The power consumption can reach below 360 degrees
◆ Simple production operation, ﬂexible incoming and outgoing materials, high degree of automation, online production can be realized; High heating speed, less oxidation and decarburization, high effciency and good forging quality;
◆ Workpiece heating length, speed, temperature, etc. can be accurately controlled;
◆ Uniform heating of workpiece, small temperature difference between core and surface, high control accuracy;
◆ Integrated design of inductor and furnace body, quick change connector for different inductor design, easy to change;
◆ Comprehensive energy-saving and optimized design, low energy consumption, high effciency and lower production cost than coal burning;
◆ Meet the requirements of environmental protection, with small pollution, and reduce the labor intensity of workers.

Power estimation formula of GTR medium frequency electric furnace

P = (C × g × T) / (0.24 × t ×∮ )
Formula Description: P-equipment power (KW); C-specifc heat of metal, in which the specifc heat coeffcient of steel is 0.17;
G - weight of heated workpiece (kg); T - heating temperature (℃ ); t - working beat (seconds);
∮ - comprehensive thermal effciency of the equipment, generally 0.5-0.7, about 0.4 for special-shaped parts.
For example, a forging plant has a forging blank of Φ 60 × 150 mm, a working beat of 12 seconds / piece (including auxiliary time), and an initial forging temperature of 1200 ℃ . Then the power calculation of GTR medium frequency electric furnace is required: P = (0.17 × 3.3 × 1200) / (0.24 × 12 × 0.65) = 359.61kw.
According to the above calculation, GTR medium frequency induction heating equipment with rated power of 400KW can be confgured.
