The X-ray spectrofluorimetry is adopted in determining chrome,silicon and phosphorus of high-carbon chrome alloy.

In this paper, the effect of Ni, Cu and Cr/C on microstructure and properties of high chromium ferroalloy is explored by the method of contrast experiment, and the development of a new high chromium ferroalloy with wear and corrosion resistance is finished.

Fe,Cr,C powder mixtures were employed to coat the surface of a low carbon steel substrate,and the Fe-Cr-C alloy layer was prepared by electron beam scanning in vacuum condition which was heated treatment at 800 ℃ for 2.

It analyzed interrelations among the carbon, silicon and sulphur in high-carbon ferrochrome, slag basicity and furnace temperature, coke's sulphur influenced on desulphurization are also discussed, many effective measures are taked for lessening sulphur content in high-carbon ferrochrome.

It analyses the changeable TiO_2 content in chrome ore and the structural form,the balance of Ti,the reaction mechanism of Ti and its existence form in alloys,the affect factor of Ti content in alloys,and benefits and control methods during the process of smelting low titanium high carbon ferrochrome.

It introduces technological condition and result of smelting high carbon ferrochrome with Xinjiang's high melting point and low grade chromes.

Based on the principle and characteristics of medium frequency furnace, analysis on physical and chemical performance of liner material , better technological economic indexes and benefits of adaptation to 2 tons medium frequemcy furnace for resmelting high carbon ferrochrome are realizde by pilot production and industrialized production.
