Study on refiing high phosphorus hot metal by combined blown converter;

Experimental study of desiliconization pretreatment of high phosphorus hot metal

Mineral phase of LD slag was studied when smelting SPHC and Q235 by high phosphorus hot metal,the results show that mineral phase of slag consist of C2S mainly,P2O5 exist in C2S phase,After de-oxygen,mineral phase of slag consist of akermanite and gehlenite mainly.

Research progress in treatment of high phosphorus iron ore and dephosphorization of high phosphorus hot metal;

Surface laser alloying processing with nickel base powder for improcing abrasiveness of high phosphorus cast iron;

After a series of experiment,the castings of high phosphorus cast iron have been gotten,whose microstructure,property and chemical composition meet the needs of the user by strictly controlling the content of elements in the cast iron and making inoculation to the molten iron.

To keep pace with power increasing of diesel engines trial to adopt high phosphorus cast iron for production of G32 model cylinder block is carried out.

Ferri phasphate was prepared by adopting different methods; and its charging discharging specific capacity in lithium storage battery was determined; and the effect of different calcining heat on its performance was studied, By the method of mechanical grinding, a ferri phosphate sample of high specific capacity was obtained.

The high iron-containing phosphate rock with iron oxide content more than 50%,can be obtained by the low intensity magnetic beneficiation of iron-containing phosphate rock.
