  • the heating amount is increased and plastic energy dissipation is used to reduce a portion of the slab in which continuous rolling may not be performed, thereby generating scrap only about 20% to 30% of scrap generated when batch rolling is switched to continuous rolling.
  • the switch between batch rolling and continuous rolling is possible, thereby greatly contributing to improving a percentage yield.
  • Table 1 below is a contrast table contrasting a case in which rolling in the initial stage is performed on condition of continuous casting and rolling equipment switching between continuous rolling and batch rolling in a normal state and a case in which rolling is performed using a method of the present disclosure not covered by the present invention.
  • a rolling reduction rate of a first rolling portion was reduced to be lower than that in the normal state, and a rolling reduction rate of a second rolling portion was increased, so that an entirety of rolling reduction rates were equal, and a degree of temperature rise of a heating portion was increased to be higher than that in the normal state by 45°C.
