KR (knotted reactor) process steel-making desulfurization molten steel liquid level detection system

The utility model discloses a KR (knotted reactor) process steel-making desulfurization molten steel liquid level detection system comprising a steel structure bracket, wherein winding engine equipment and a winding lifting track are arranged on the steel structure bracket; a winding trolley is arranged on the winding lifting track; a stirring head is arranged on the winding trolley; a winding steel wire rope of the winding engine equipment is connected with the winding trolley; a tension sensor is arranged on the winding steel wire rope; a positioning encoder is arranged on an output shaft of a speed reducer of the winding engine equipment; the tension sensor and the positioning encoder are respectively connected with a PLC (programmable logic controller) controller by virtue of a data line. According to the KR process steel-making desulfurization molten steel liquid level detection system disclosed by the utility model, whether the stirring head is inserted into the liquid level of molten steel can be qualitatively detected according to the tension change of the tension sensor in the uniform lifting process of KR process stirring equipment, the actual height of the liquid level of the molten steel can be accurately detected, and height data is fed back to a desulfurization automatic control system to participate in desulfurization control so as to precisely control the insertion depth of the stirring head, optimize the dynamic performance of desulfurization, and improve the desulfurization efficiency.
