BUTT WELDING METHOD FOR HOT STEELS

摘要

PURPOSE:To easily joint hot steels in a short period during traveling by sliding the other joining face for one joining face to give frictional force to both joining faces. CONSTITUTION:The hot steels 2 and 3 of a hot line 1 are joined together during traveling. At least one end of the rear end 2a of the preceding hot steel 2 or the tip 3a of the succeeding hot steel 3 is then fixed on a traveling means to travel in the moving direction A of the hot line 1 and the other end is pressed against one end relatively while moving in the moving direction A. The joining face of the other end is then slid for the joining face of one end and the frictional force is given to both joining faces to join the rear end 2a of the preceding hot steel 2 to the tip 3a of the succeeding hot steel 3. A traveling carriage 6, clamping devices 10 and 25, a frictional sliding device 23, etc., are used for pressing and sliding of the joining face in this case. Consequently, it can be done without bringing about drastic extension of the hot line.
