For the improvement of the yield in making a slab from an ingot, it is important to decrease crop loss. Studies have been carried out to reduce crop loss, mainly by using plastcine as model rolling material, and the results are summarized as follows : (1) A high-lift mill has an advantage over a universal mill. A high-lift universal mill is the best type of slabbing mills when productivity is taken into account in addition to the yield of product. (2) Crcp loss can be drastically reduced by making the bottom shape of a flat bottom ingot to compensate overlap and fish-tail obtained by rolling it. (3) A new rolling method has been developed for reduction of crop loss, on the basis of the fact that overlap and fish-tail are smaller at the front end than the tail end of rolling. In this method the rolling end is sufficiently rolled at the preceding pass to avoid rolling at tail end at the earlier stage of passes.
