Abstract

PURPOSE:To give efficiently a linear small strain on the surface of a steel plate without stopping of the steel plate by providing in opposition a press roll to the strain giving roll which forms a spiral projection part on the peripheral face and by moving the steel plate between both rolls or driving the press roll. CONSTITUTION:A strain giving roll 3 is composed of a bar shaped body 1 and by forming a spiral projection part 2 on the surface thereof. The spiral projection part 2 is constrained as per the following: (1) The winding direction of twist may be either the right or left and may be the combination of the right and left directions. (2) The pitch in twist is made by the prescribed range value according to the necessity. (3) The twist crest shape may be in any shape if causing no flaws on the surface of the steel plate. (4) The angle of twist may be optional if being the value within the presribed range. The material of the bar like body employs an iron, aluminum and hard plastics. The strain giving roller 3 is oppositely provided on the press roll 4. A continuous linear small strain is given on the surface of the steel plate 5 when it is spread be tween both rolls and passed at fixed speed and the strain giving roll 3 is subjected to adequate rolling reduction.
