Problems solved by technology

Because the local heat treatment strengthening of the rail needs to heat the entire cross-section for a long time, there will be a certain length range of temperature and structure transition zone between the heated and non-heated parts of the rail. In this zone, the metal structure will be uneven due to the temperature gradient. A certain range of granular structure produces a certain width of hardness softening zone. Such a large softening zone will easily lead to local rapid wear caused by long-term impact, vibration and rolling in actual line applications, that is, the so-called saddle wear. It is not conducive to the smoothness of train operation, will affect the efficiency of line operation in the long run, reduce the service life of rails, and increase line maintenance costs

Embodiment 1

[0044] like figure 1 As shown, the flow of the rod heating method according to an embodiment of the present invention includes:

[0045] Step 102: Heat the preset position of the rod member;

[0046] Step 104, when the heated time reaches the preset time and / or the heated temperature reaches the preset temperature, the rod member is moved to the heating unit to move the preset distance to the heating unit.

[0047] During the heating method of this embodiment, the rod is heated during the heating method, and the rod member is continuously heated to the heating device, in this manner, in this manner can significantly shorten the rod to local heating. In the process, the temperature and the length of the tissue transition zone at the heating unit are significantly shortened, and the length of the heat affects the tissue of the spheroidal region is significantly shortened, and the hardness of the heat affected zone is improved.

[0048] Further, the timing and / or temperature of the...

Embodiment 2

[0051] like figure 2 As shown, the flow of the rod heating method according to an embodiment of the present invention includes:

[0052] Step 202, heating the preset position of the rod member;

[0053] Step 204, when the heating time reaches the preset time, the rod member is moved to the heating unit to move the preset distance;

[0054] Step 206, after continuing to heat to the target temperature, after insulation to the target time, the rod is removed by the heating unit.

[0055] In this embodiment, the heating temperature is further heated until the heating temperature reaches the target temperature and the heat insulation target time, ensuring the predetermined heating effect, and then moves the lever out of the heating unit Cool, complete the heating of the rod.

[0056] Alternatively, the value range of the preset distance is greater than or equal to 50 mm.

[0057] In this embodiment, the selection of the preset distance is positively correlated with the rod heating targ...

Embodiment 3

[0061] like image 3 As shown, the flow of the rod heating method according to an embodiment of the present invention includes:

[0062] Step 302, heating the preset position of the rod member;

[0063] Step 304, when the heated temperature reaches the preset temperature, the rod member continues to heat the preset distance within the heating unit;

[0064] Step 306, after continuously heating to the target temperature, after insulation to the target time, the rod is removed by the heating unit.

[0065] Alternatively, the value range of the preset distance is greater than or equal to 50 mm.

[0066] Alternatively, the heating temperature reaches the preset temperature comprises: obtaining the heating temperature at the preset position reaches the first temperature threshold; and / or acquire the heating temperature of the rod member at the holster of the heating unit to reach the second temperature threshold.

[0067] In this embodiment, the heating temperature of the rod member i...

Abstract

The present invention provides a rod heating method, heating equipment and computer-readable storage medium, wherein the rod heating method includes: heating a preset position of the rod; when the heating time reaches the preset time and / or the heating When the temperature reaches the preset temperature, the rod is moved into the heating unit for a preset distance to continue heating. The rod heating method of the present invention can significantly shorten the temperature of the rod at the furnace mouth of the heating unit and the length of the tissue transition zone during the local heating process, significantly shorten the length of the tissue in the nodularization zone affected by heating heat, and increase the hardness of the heat-affected zone .

Description

Technical field [0001] The present invention relates to the field of workpieces, and in particular, therefore relates to a rod heating method, a heating apparatus and a computer readable storage medium. Background technique [0002] With the rapid development of the railway to the high-speed overload direction, the line transport density gradually increases, and the smoothness requirements of the train operation are also increasingly high, to further extend the service life of the rail rail, improve the safety and reliability of operation, currently Railway Corporation requires that there is a wire-heat-treated rail, which is used as a non-symmetric section of the key components in the Taxi. It is connected to the non-symmetric section of the key components, the heart rail and different rail line connectors. The hot forging and the line can be conveniently coupled to another standard rail, which is still thermally treated with the local area of ​​the forging due to the local perf...
