Description
Technical field
The present invention relates to manganese element additive that uses in a kind of steel alloy smelting process and preparation method thereof.
Background technology
Manganese is a kind of important interpolation element in the steel alloy.The adding of manganese can improve the intensity and the plasticity of steel alloy, improves the work hardening capacity and the wear resistance of steel alloy, effectively improves the hardening capacity of steel alloy, and the intensity that improves low-carbon (LC) and middle carbon perlitic steel is had significant effect, improves the high temperature instantaneous strength of steel.
The existing manganese addition method of steel alloy in smelting mostly is the interpolation manganeseirom.This technology generally is to add ferromanganese in decarburization II phase and III phase, because carbon content is higher in the manganeseirom, the concentration that this can improve Mn and C in the molten metal has reduced the temperature of molten metal simultaneously.Lower in blowing molten metal temperature in early stage, Mn to the avidity of O greater than C, when molten metal temperature during greater than 1400 ℃, the avidity of C and O just surpasses Mn, so this kind manganese addition method can increase the Mn amount of oxidation, prolong and take off C tap to tap time, not only the rate of recovery of Mn is on the low side, increases the control difficulty of decarburization difficulty and carbon content, and prolongs the time that converter is on average smelted, also have influence on the life-span of furnace lining, increased ton steel cost.For some high tensile steel alloys,, can not adopt this kind addition manner because its requirement to C content is very strict.
Summary of the invention
