This paper describes the metallurgical theory for Ba and the productive practice of Si-Ba series ferroalloys as well as its application to the ferrous metallurgy.
Application of artificial neuralnetwork inend-point composition and temperature prediction for the whole ferrous metallurgy process include sintering, ironmaking, steelmaking (hot metal pretreatment, converter, electric arc furnace), secondary refining (Ladle furnace refining and RH refining) are summarized.
There is the better application prospect for the application of artificial neural network in end-point prediction for the whole ferrous metallurgy process.
A precise, sensitive and simple extraction-spectrophotometric method for determination of molybdenum in products from ferrous metallurgy has been developed.
The effect of foreign ions and reagents was studied and a competitive method for determination of tungsten in products from ferrous metallurgy was developed.
In this paper, we shall discuss the research report on the feasibility mining engineering of Baoshan Copper Mine in the second phase of the project covering the mining method, underground mining method and mine production capacity suggested by the Lanzhou Designing Institution of Non- ferrous Metallurgy, and shall make an all-round demonstration and analy- sis. The different conclusions are suggested as follows, The conclusion that the sublevel caving method can be used as the major basis in de...
Among the products of non-ferrous metallurgy,plenty of energy for production of copper and nickel metallurgy has been consumed. This paper discusses the character of extraction technology of copper and nickel, analyses and contrasts their difference of energy consumption at home and abroad, presents the measures and ways of energy-saving in copper and nickel metallurgy respectively.
Determination of Sr in ferrous metallurgy by flame atomic absorption spectrophotometry has been studied. The optimum conditions of instrument was selected. The different concentration of varying acid medium and the interference of twenty-seven coexisting elements on the determination of Sr has been investigated. The various interference depressing agents have also been examined. The lanthanum chloride is selected as releasing agent for eliminating the interference of P(PO_4~(3-)) Si(SiO_3~(2-)) ...
