EFD Induction landed three major induction hardening orders from China’s coal-mining industry. The orders involve hardening and tempering lines for 5- to 60-mm-diameter chain. The systems are being constructed at EFD Induction facilities in Norway and China and are due for delivery in the first half of 2012. The first order involves an induction hardening and tempering solution for the China Coal Zhangjiakou Coal Mining Machinery Company (CZCM). CZCM plans to install the EFD Induction hardening line, which will feature four induction heating units, in a new chain manufacturing plant.
The second order involves a complete hardening and tempering
line for the Xian Heavy
Equipment ChengHe Coal Machinery Company. The line, which is
designed for 24- to 36-mm-diameter chain, will include four induction heating
units. The third order – from the Changchun Northeast Conveyor Equipment
Manufacture Company – is for a hardening and tempering line for 36- to 60-mm-diameter
mining chain. The line has six induction power sources and an hourly output
capacity of up to 2,000 kg.
