| description | The utility model discloses a normalizing coil for a steel rail welding joint. The normalizing coil for the steel rail welding joint can improve the grain size in the middle of the rail bottom and is characterized in that the normalizing coil is composed of two turns of coil bodies arranged in an approximately parallel mode, and the steel rail penetrates through the interior of a ring composed of the coil bodies; part of each turn of coil body offsets outwards in a corresponding mode, and the interval of the portions, offsetting outwards, of the two turns of coil bodies is increased. The normalizing coil can effectively reduce the heating temperature in the middle of the rail bottom of the steel rail welding joint, guarantee the mechanical property and high toughness superplastic of fine grain and a microstructure of the middle of the rail bottom of the steel rail welding joint and is also suitable for other portions, needing reduction of the heating temperature, of the steel rail. |
