Based on the actual site conditions, a non-standard design is adopted to provide a billet feeding mechanism that solves the problem that the billets in the billet discharge roller table of the steelmaking continuous casting process cannot be smoothly transferred to the conveying roller table of the rolling process. The newly added billet feeding mechanism realizes the smooth transfer and conveying of billets between the steelmaking and rolling processes. Moreover, the equipment has a reasonable design structure, is easy to disassemble, and is simple to maintain. It can adapt to the high requirements of the equipment under the high temperature of hot billets.
