A small special alloy shop received an order for slabs of an experimental superalloy 4 in. wide and 1/2 in. thick. The shop cast ingots 4 × 4 × 12 in. and hot-rolled them in a 12-in.-diameter mill, making reductions of about 5% per pass. On the ?fth pass, the ?rst slab split longitudinally parallel to the rolling plane. The project engineer, the shop foreman, and a consultant met to discuss the problem. The consultant proposed applying forward and back tension during rolling, the project engineer suggested reducing the reduction per pass, and the shop foreman favored higher reductions per pass. With whom would you agree? Explain your reasoning.
