Endless rolling strip steel flexible production line and production process

The invention discloses an endless rolling strip steel flexible production line and a production process. The production line is arranged behind a continuous casting machine and comprises a pre-rolling unit, a tunnel furnace, a roughing rolling unit, an induction heating device, a finishing rolling unit, a laminar cooling device and a coiling unit which are sequentially arranged. Wherein the pre-rolling unit is used for pre-rolling or idle rolling; the distance between the rough rolling unit and the finish rolling unit is 15-45 m; the tunnel furnace is used for carrying out temperature equalization treatment; the induction heating device is used for temperature adjustment. According to the production line, the three units including the pre-rolling unit are arranged, the tunnel furnace and the induction heating device are adopted in the heating procedure, the distance between the roughing rolling unit and the finishing rolling unit is improved, the application capacity of wider steel passing amount is achieved
