120 Tons Electro Slag Re-melting Furnace Put into Operation

The revamp key project of 120 tons electro slag re-melting furnace put into operation in Hydraulic Press Workshop of Steel Casting and Forging Business Department, successfully cast 80-ton class electro slag ingot at 10 am on August 26^th. Chairman of Board of CFHI Wu Shengfu, leaders of Steel Casting and Forging Business Department were at present during the operation. The operation of this equipment marked CFHI has already had the ability of supply high quality of electro slag ingot for low carbon stainless steel forging such as ultra-supercritical power station high-medium pressure rotor and nuclear power main pipe line, met the production demand of key forging with large scale high quality and high purity, improved the technical level of China s large scale electro slag melting equipment, cemented the solid foundation of improving large scale forging extremely ability, to realize the localization of high end forging, build world class casting and forging base.

The feature of electro slag metallurgy after electro slag re-melted, is not only with high purity, good surface, high availability coefficient of ingot, oriented crystallization and compact structure, but also eliminate the disadvantage such as anisotropy, macrosegregation, shrink hole and inclusion inside of normal large scale ingot specially in the field of key products such as nuclear power, ultra-supercritical rotor, hydrogenation and military product, has irreplaceable superiority.

It is the second hundred tonnage large scale re-melting equipment in China, there is unique design on the mechanical drive and short network, driven by hydraulic drive method in integrity, dipolar series power supply design for circuit, greatly reduce the loss of quantity of electricity in the network, reduce the current drain, intelligent control, which is the most advanced hundred-ton class above electro slag equipment.
