In the early days, two high rolling mills were used to roll plates and strips. Because the rolling pressure is very large when rolling plate and strip, in order to ensure sufficient rigidity, the roll diameter is required to be large enough. However, with the increase of roll diameter, the elastic flattening of roll also increases, so the two high mill can only roll thick narrow strip.
