摘要： PROBLEM TO BE SOLVED: To provide a rolling mill for a wire and bar which can manufacture a product of high dimensional accuracy by controlling only the rolling counterforce of a finish block mill and a reducing mill, without the necessity of controlling the rolling reduction of a rolling mill at the upper stream side and without exposing a strain gauge to cooling water, radiant heat of heated steel and dust. SOLUTION: A rolling counterforce detecting rod 20 is fitted to a housing 12 in a state of piercing through the housing 12 which, as a cantilever support, supports the upper end lower reduction rolls 13 and 14 of a roll unit 11 at the upper stream side of the finish block mill. A difference is found between the rolling counterforce determined by the rolling counterforce detecting rod 20 and the strength limiting value of a metal bearing. If the difference is normal, the volume of cooling water for the wire and bar cooling zone is controlled. If the difference is so great that the rolling counterforce exceeds the strength limiting value of the metal bearing, the volume of the cooling water and the interval between the upper and lower reduction rolls 13 and 14 are controlled. In the case of a further great difference, the temperature of a lubricating oil is also controlled.
