Information × Registration Number 0215U000948, 0114U004913 , R & D reports Title Research on the impact of bottom blowdown on the quality of cast metal and efficiency of electric-arc furnace. popup.stage_title Head Trotsan Anatoly Ivanovich, Registration Date 29-07-2015 Organization State Higher Educational Institution "Pryazovskyi State Technical University" popup.description2 The object of research - the process of bottom blowing of steel in electric arc furnaces with inert gas in finely nucleate mode. Purpose - to test the bottom purge flow; to improve the melting of metal stock; reduce the cost of production of steel in electric arc furnaces; improve the yield and properties of steel and cast steel structure finished. Research methods and equipment - physical modeling of hydrodynamic processes in the laboratory; physical modeling of hydrodynamic processes in a particular metallurgical vessel; test purge unit in an industrial environment. The results - time of desoxydating is diminished, thus reducing the consumption of ferroalloys by 1 kg/ton of finished product; improved low viscosity of the melt and get more fine-grained casting compared to casting, cast without the proposed bottom blowing device; resistance of bottom blowing device exceeded resistance furnace lining; reduced power consumption for 23.81 %, compared with the established norms of 1 ton of finished product, due to the accelerated melting of the raw materials. The first time the bottom of the melt blowing in finely nucleate mode on a production. It is proposed to use a bottom blowing on engineering and metallurgical enterprises.
