The invention relates to a hot galvanizing slag on-line recycling system which comprises a hot galvanizing assembly used for carrying out hot galvanizing on strip steel, and the hot galvanizing assembly comprises a zinc pot; the centrifugal separation device is used for separating metal zinc in the zinc slag generated in the hot galvanizing process, and the centrifugal separation device is arranged below the liquid level of the zinc pot; and the metal zinc automatically flows back into the zinc pot from a lower opening of the centrifugal separation device. The technical problem that zinc slag generated in an existing hot galvanizing process is difficult to effectively recover is solved. 本申请涉及一种热镀锌渣在线回收利用的系统，所述系统包括：热镀锌组件，用于对带钢进行热镀锌，所述热镀锌组件包括锌锅；离心分离装置，用于分离出所述热镀锌过程中产生的锌渣中的金属锌，所述离心分离装置设置于所述锌锅的液面以下；所述金属锌自动从所述离心分离装置的下口流回所述锌锅内。本申请内容解决了现有热镀锌工艺中产生的锌渣难以有效回收的技术问题。
