The compression and decompression method of the frame data has the characteristics of high compression rate and high reduction rate, and by simplifying the data processing unit and improving the compression rate and the reducibility, the occupied capacity in the storage and transmission process is reduced, the transmission rate is increased, the transmission time is shortened, and meanwhile, the real-time performance and the stability of the data are guaranteed.

A converter smelting method for increasing residual manganese in molten steel with high manganese and high silicon
ActiveCN109136452BIncrease the residual Mn contentIncrease distribution concentrationManufacturing convertersProcess efficiency improvementSteelmakingSmelting process
The invention discloses a converter smelting method for improving end-point molten steel residual manganese in high-manganese and high-silica molten iron (4.40 to 4.80 weight percent of C, 1.10 to 1.30 weight percent of Mn, 0.75 to 1.00 weight percent of Si, 0.085 to 0.105 weight percent of P and 0.015 to 0.035 weight percent of S). According to the method, by adopting technologies such as low alkalinity slag making technology, constant pressure gun change operation at gun position during smelting process, converter inverting gun pressing operation at minimum gun position, steel tapping whole-process wash heat process and carrying out integrated innovation, kinetic and thermodynamic conditions of smelting reaction are optimized, the distribution concentration of the slag (MnO) in the smelting process is improved and better smelting dephosphorizing effect is obtained under the conditions of less slag and a low basicity slag system; moreover, molten steel rephosphorization at the late smelting period and in the steel tapping process is reduced to the maximum extent, so that the residual Mn content (0.48 to 0.65 weight percent) of end-point molten steel is significantly increased, theadding amount of a manganese alloy during the deoxygenation alloying process is significantly reduced, the consumption of steelmaking alloys and the alloying cost are reduced, the improvement of smelting technical and economic indicators is promoted and further the market competitiveness of a product is improved.
