The invention relates to a method capable of realizing on-line prediction of crystallizer flow field flow state in actual production, and belongs to the technical field of
continuous casting processesof
ferrous metallurgy steelmaking. According to the technical scheme, three rows of steel nail plates are manufactured according to the section sizes of a crystallizer and a
water gap, penetrate through a stainless steel support placed near the
water gap and a
narrow face of the crystallizer to be vertically inserted into the liquid level of the crystallizer from the two sides of the
water gap atthe same time under different
casting parameter conditions, and are vertically lifted out after several seconds; and the
diameter of
metal blocks adhered to steel nails, the distance from the highestpoints and the lowest points of the
metal blocks to the
tail ends of the steel nails are measured correspondingly, and the
height difference of the
metal blocks at the highest points and the lowest points on two sides of the steel nails is calculated. The method capable of realizing on-line prediction of crystallizer flow field flow state in actual production has the beneficial effects that the advantages and disadvantages of the current
continuous casting parameter conditions can be visually explained, a crystallizer flow field flow state
transition diagram can be drawn based on a flow statemeasurement result, and
casting parameters are optimized and adjusted in real time according to the field production
rhythm, so that
molten steel in the crystallizer is in a stable flowing state, andthe
casting blank quality is improved.
