본강특수강엄채용50t EBT-LF-VD-련주(235mm ×265mm)생산 FAS3420H치륜강。통과공제전로종점탄≥0.07%,안목표성분공제〔S〕、〔Al〕급Ca/Al치,련주강수과열도25~40℃,공작랍속0.90m/min등공예조시,피면료련주과정적수구도새,사득련주련요로수유3~6로제고도9~11로。
Using the program 50tEBT-LF-VD-caster, special steel plant of Benxi steel produces gear steel FAS 3420H, In order to avoid the nozzle clogging during continuous casting , we carry out such measures as controlling the terminal carbon of electric furnace≥0.07, controlling 〔S〕,〔Al〕 and Ca/Al values according to the target composition , keeping the casting superheat at 25-40℃, and work pulling speed at 0.90 m/min.As a result, the continuous times increase from 3-6 to 9-10.
