Claims

[Claims for Utility Model Registration] (1) In the heat treatment process using the slack quench method, a preheating furnace 8 is provided in front of the rapid heating furnace 4, and on both side walls of the rapid heating furnace 4, there is a preheating furnace 8 that collects only at the top of the rail head. An inward L-shaped heat shield plate 4a for heating is installed vertically, and the front end surface 11 of the air box 3 of the air cooling device 2 that follows the rapid heating furnace 4 is connected to the rapid heating furnace 4.
Inlet width adjustment plate 12 that prevents air from flowing backwards to the side
are attached via bolts 13, and water injection pipes 5 are installed below both sides of the rapid heating furnace 4 to the flanges of the rail, and water injection pipes 5 are installed below both sides of the air cooling device 2 to the lower part of the jaw of the rail. A rail heat treatment device characterized in that a water injection pipe 18 to the rail head is provided near the outlet of the air cooling device 2 in order to prevent large bending of the rail due to thermal strain. (2) The inward L-shaped heat shielding plate 4a is equipped with an access adjustment plate 6 having a guide slot 6a in its short horizontal portion via a bolt 7. Rail heat treatment equipment. (3) The air box 3 of the air cooling device 2 is divided into a first quenching chamber 3a for high-pressure air and a second quenching chamber 3b for medium-pressure air. Rail heat treatment equipment. (4) Preheating furnace 8, rapid heating furnace 4, and air cooling device 2
Practical system in which automatic levelers 16a and 16b are incorporated into each of the level sensors 16a and 16b, which are composed of level sensors 20a and 20b that detect the distance from the top surface of the rail 1 and vertical drive devices 15a and 15b that operate in conjunction with the level sensors 20a and 20b, respectively. A heat treatment apparatus for rails as set forth in any one of claims 1 to 3.
