Abstract: The present invention belongs to the field of heat treatment for metal plate strips, and discloses a water spray system for heat treatment of metal plate strips and a control method. The system comprises a shunt water collector, sub-water supply pipelines, a control valve group and a control system. The control method comprises a water pressure regulating method and a water flow regulating method. The shunt water collector adopts multi-pipeline uniform flow design and realizes uniform shunt and constant pressure water supply. The sub-water supply pipelines are designed with three configuration modes of a control valve group in accordance with varieties and specifications of metal plate strips, rhythms of production and heat treatment technologies to realize dual closed-loop control of water pressure-water flow.

Abstract: An application of an antibody conjugate in the preparation of a drug for treating CD30 positive tumors, which is characterized in that: the antibody conjugate is F0002-ADC; the general formula of the structural thereof is Ab-Lm-Yn; and the CD30-positive tumors are CD30-positive tumors that express a multidrug resistance gene 1. In addition, a pharmaceutical combination and a pharmaceutical composition containing the antibody conjugate, which may be applied to the preparation of a drug used for treating CD30-positive tumors.

Abstract: Heat treatment equipment for metal plate strips, and a roller quenching flow zone control device for metal plate strips. The device includes a middle water diversion ring sleeve and edge water diversion ring sleeves; the middle water diversion ring sleeve is installed at the middle processing groove in a slit nozzle rear spiral roller and a high-density nozzle rear spiral roller in a high-pressure cooling section of a roller quenching machine; and the edge water diversion ring sleeves are installed at the processing grooves in ¼ and ¾ positions in the width direction of the slit nozzle rear spiral roller in the high-pressure cooling section of the roller quenching machine. This can effectively realize uniform distribution of cooling water on the surface of the plate strip, reduce the phenomenon of local non-uniform cooling caused by siltation of cooling water.
