The invention relates to an off-line flame cutting machine. The flame cutting machine is arranged on a worm gear case body and a movable trolley shell. The flame cutting machine comprises a worm, a thrust ball bearing, a deep groove ball bearing, a bearing pedestal, a bearing cap, a transmission shaft, a fan blade, a panel, a guide sleeve, a nozzle and a regulating valve. The worm and the fan blade are arranged at the two ends of the transmission shaft correspondingly. The thrust ball bearing and the deep groove ball bearing are arranged on the rear portion of the transmission shaft. The transmission shaft is arranged inside the bearing pedestal. The bearing pedestal is provided with the bearing cap. The bearing pedestal is connected to the worm gear case body. The panel is fixedly connected to the movable trolley shell. The guide sleeve is arranged on the panel. The nozzle penetrates through the guide sleeve and is opposite to the fan blade in position. The upper portion of the nozzle is connected with the regulating valve. The off-line flame cutting machine is simple in structure, convenient to control, and capable of lowering the internal temperature of the cutting machine and prolonging the motor service life.
Description
technical field [0001] The invention relates to a secondary cutting device for slabs in steel continuous casting production, in particular to an off-line flame cutting machine. Background technique [0002] In continuous casting of iron and steel, the slab coming out of the mold is continuous. As the final process in the continuous casting process, flame cutting needs to be cut to the required length with a flame cutting machine. Limited by the cutting stroke of the primary (online) flame cutting machine and the drawing speed of the steel billet, the steel billet cut online to a fixed length needs to be cut twice (halved or thirdly divided) before rolling. There are usually two schemes. One is to arrange a secondary flame cutting machine across the roller table at the lower end of the primary flame cutting machine. Its structure is the same as that of the primary flame cutting machine. It is characterized by large investment and high automation, but low efficiency. . The ...
