Abstract
The utility model relates to a rail thermal treatment's test device, including the support, characterized by: the support is one section 1-1.2 meter and grows up to article rail section, and it has a recess that transversely link up to open at the top of support intermediate position. Its advantage is: can simulate the thermal treatment state of finished product rail through this test device, realize the rangette and smelt the test requirement of new steel grade on thermal treatment pilot scale line, guarantee for the industrialization trial -production of the new steel grade of thermal treatment provides the reliable experimental performance in earlier stage to the risk of effectively having avoidd industrialization trial -production.
Description
Technical field
The utility model relates to a kind of experimental rig of heat-treatment of rail, belongs to heat treatment technics field.
Background technology
Along with railway transportation is progressively to the development of high speed, heavy duty, the intensity to rail and the hardness of rail head are had higher requirement. The intensity and the tread hardness that improve rail by optimizing the steel grades of rail and Technology for Heating Processing thereof are a kind of comparatively energy-conservation, economic methods. At present, the heat treatment test of rail is to carry out on the existing heat treatment pilot plant test line in laboratory. The test specimen of this test wire is the standard finished products rail of 1.0 ~ 1.2 meters long, needs first in heating furnace, be heated to set temperature insulation when test, comes out of the stove to be afterwards placed in the reversible transfer roller of heat treatment pilot scale line and heat-treats. The cooling device of heat treatment pilot scale line carries out design and installation according to standard rail, and its distance and angle can regulate within the specific limits. This heat treatment pilot scale line can be realized the heat treatment pilot plant test of the hot rolled rail of existing steel grade, for the experimental study of further heat treatment new steel grade port, still belongs to blank.
Summary of the invention
The purpose of this utility model is to provide a kind of condition of heat treatment that can simulate finished product rail, realizes the experimental rig of the heat-treatment of rail of the test requirements document of port smelting new steel grade on heat treatment pilot scale line.
The purpose of this utility model is achieved in the following ways:
The utility model comprises bearing, it is characterized in that: bearing is one section 1 ~ 1.2 meter and grows up to product rail section, has the groove of a lateral direction penetrating in the crown center position of bearing.
The longitudinal cross-section of described groove is rectangle.
The utility model has the advantages that: the condition of heat treatment that can simulate finished product rail by this experimental rig, realize port and smelt the test requirements document of new steel grade on heat treatment pilot scale line, for providing the reliable experimental performance in early stage, the industrialization trial-production of heat treatment new steel grade ensures, thus the risk of effectively having evaded industrialization trial-production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The design starting point of this experimental rig: the one, how to realize test specimen and can on the roller-way of existing heat treatment pilot scale line, walk, the position of simultaneously not changing as far as possible nozzle, realizes the effective cooling of cooling device; The 2nd, the amount of port test new steel grade is restricted, and general 25 ~ 100kg/ stove, and code test rail is 60,75kg/ props up is obviously directly forged or rolled into the test specimen with rail profile and not only measures large not but also difficulty is large; The 3rd, port test steel sample is little, and thermal capacitance is little, rapid heat dissipation, how can make the condition of heat treatment of its simulation finished product rail.
The utility model comprises bearing, it is characterized in that: bearing is one section 1 ~ 1.2 meter and grows up to product rail section, and have the groove of a lateral direction penetrating in the crown center position of bearing, the longitudinal cross-section of groove is rectangle. The width of groove is that 250 ~ 300mm, the degree of depth are 30 ~ 35mm.
When test, the test steel that port is smelted through forging rolling be processed into experimental rig on the cuboid piece sample that matches of groove size, be placed in groove, gap between both sides and groove is fastening with Metallic card, together enter heating furnace and be heated to design temperature insulation, come out of the stove into heat-treatment lines test, finally take off sample and carry out coherent detection analysis. Advantage of the present utility model has been to ensure that sample can walk on the roller-way of heat treatment pilot scale line, and nozzle location need not be moving greatly, meanwhile, by the thermal capacitance of rail bearing, effectively simulate the condition of heat treatment of finished product rail, thereby realized the test requirements document of port smelting steel.
Claims (2)
1. an experimental rig for heat-treatment of rail, comprises bearing, it is characterized in that: bearing is one section 1 ~ 1.2 meter and grows up to product rail section, has the groove of a lateral direction penetrating in the crown center position of bearing.
