Installation of thermal treatment of welded rail joints in technological conditions STATIONARY

摘要

Installation of heat treatment of the welded joints of the rails in the stationary process conditions relates to the field of heat treatment of the welded joints, for example, elongated rails and jointless lashes, and can be used to correct zonal structural nonuniformity after welding on railway, urban and industrial truck in a rail welding train (FPR ). Target Utility Model - construction of induction heating for the heat treatment of the welded joints of the rails in the stationary process conditions of low weight and size, freely moving along the runner rail, while reducing costs and operating costs, but with improving the quality of welded joints of heat treatment of rails. Installation in accordance with the utility model comprises a frame with guides for the free movement termoagregata along rail runner, termoagregat formed as arched structures mounted on the rail whip on the platform and on one of the arches mounted drive vertical movement of the inductor assembly and the sprayer, sprayer fixedly secured to end of said rack drive sprayer is suspended on the inner arched structure movable along said guide rail and mounted on the Set hydrochloric platform at said inner arch rigidly fixed drives horizontal movement inductors inductor assembly, each of which is mounted on the end of the respective slats above said drive horizontal movement of inductors on the other two arches mounted on a platform mounted control unit and the matching block associated with inductors with flexible tires. Sprayer associated with the quenching medium supply device via an electrical pneumatic valve associated with the control unit, and as the quench medium using compressed air. Using as the quenching medium the compressed air provides a more uniform and stable distribution of hardness of the rolling surface in the weld zone than during quenching air-water mixture due to more stable operation of the air tempering apparatus.
