摘要： A continuous manufacturing method for a metal welded tube and a manufacturing apparatus therefor, which obtains a tubular member by continuously passing a metal band coil through molding rollers, guides the tubular member to abutting rollers to bring the edges thereof in slight contact with each other so as to form a V-throat having the vertex of an edge contact portion at the upstream side of the abutting rollers, disposes an inductor of a high frequency preheating unit aiming at edge preheating at the outer periphery in front of the abutting point of the V-throat and at need disposes an impeder also at the inner surface of the V-throat, and further disposes welding torches in a single or double rows of a welding unit for melting and welding the tubular member by welding high density energy at the upstream side of the abutting rollers including the line connecting the centers thereof.

摘要： In a horizontal continuous casting machine having a casting withdrawing cycle consisting of withdrawing, stopping and push-back periods, a method of controlling the stop of the flow of a casting during the stopping period of the withdrawing cycle so as to stop the flow of the casting within a predetermined period. The desired braking torque is calculated in consideration of the load variations due to the casting condition of the horizontal continuous casting machine and the braking torque is applied to the pinch roll shafts upon the termination of the withdrawing period thereby effecting the stop of the flow of the casting during the stopping period within the predetermined time.
