Installs and adjusts equipment, such as rolls, guides, scale breakers, shears, and coilers, in mill train, using handtools. Observes steel passing through finish rolls for specified straightness, flatness, and finish. Observes gauges to verify specified electric load and temperature. Moves controls to adjust electric load, speed of mill, and tension between rollers to equalize mill load and obtain product of specified finish and dimensions. Inspects product for defects, using x-ray gauge. Directs crew in roll changes, removal of cobbles from rolling line, and polishing rolls.
