According to the major element compositions,three types of balls can be divided:(1)high Fe-Ti balls;(2)S-Fe-Ni balls;(3)light-colored s.

The situation of smelting high titanium ferroalloy in the laboratory is briefly introduced.

At present producing of high titanium ferroalloy mainly.

At pressent, the major method of producing top-quality high titanium ferroalloy is remelting, however, this method is used waste titanium as raw materials and the production cost is relatively high, which restricts its extensive application.

Determination of manganese,phosphorus and vanadium in the iron slag with high content titanium by inductively coupled plasma atomic emission spectrometry;

To the problems that residual oxygen content is high and deoxidizing difficult in the production process of high ferrotitanium by adopting aluminothermic deoxidization method,through observing the microstructures of oxygen element in high ferrotitanium by the numbers,the conformation of oxygen element in high ferrotitanium is determined.

Due to the exhaust temperature increases with the increasing compression ratio of the engine,the exhaust manifold materials had experienced several stages including grey cast iron,ductile iron,silicon-molybdenum ductile iron and high nickel ductile iron.
