Description

Technical Field

[0001] The utility model relates to the technical field of induction heating furnace devices, in particular to a horizontal push type steel billet induction heating furnace. Background Art

[0002] Rebar, steel sections and other steel products are made by heating continuous cast billets and then sending them into rolling mills. The traditional way to heat billets is to heat them in heating furnaces such as natural gas, coal gas, and fuel oil. In recent years, induction heating furnaces have been widely used to heat billets.

[0003] The traditional induction heating furnace is a longitudinal walking structure with multiple heating furnace bodies arranged in a row. The billets are transported by transmission rollers. The billets pass through each furnace body one by one, and the temperature gradually rises to the rolling temperature before being sent to the rolling mill. However, the traditional induction heating furnace still has certain shortcomings when used:

[0004] The traditional heating furnace generally includes two groups of heating units, a total of six furnace bodies, as well as a feeding mechanism and a steel-outlet track. The overall equipment occupies a large area. At the same time, the heating method of the longitudinal walking heating furnace is to heat one billet after another through the heating furnace. Only one billet can be heated in the furnace each time. Even if 6 furnace bodies are set up, the total heating time of each billet is still relatively short, which belongs to the form of rapid heating. Even if a uniform temperature and heat-transmitting area is set, there is still a temperature difference of about 50°C on the core surface of the billet after it leaves the heating furnace. This temperature difference may not meet the requirements for some varieties with high rolling requirements. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1:

[0025] Reference Figure 1 , a horizontal push type billet induction heating furnace, comprising a furnace body 4, and further comprising:

[0026] A conveying assembly, the conveying assembly is connected to the furnace body 4;

[0027] The conveying assembly includes a first conveyor belt 301 and a second conveyor belt 1;

[0028] The first conveyor belt 301 is located directly in front of the feeding end of the furnace body 4;

[0029] The second conveyor belt 1 is located directly behind the discharge end of the furnace body 4;

[0030] A support plate 6, arranged on the side of the first conveyor belt 301;

[0031] A pusher assembly, fixedly connected to the support plate 6;

[0032] The feeding rack 4011 is arranged at the front end of the furnace body 4, and the upper end surface of the feeding rack 4011 is flush with the feeding port of the furnace body 4.

[0033] It should be noted that the upper surface of the first conveyor belt 301 is flush with the lower surface of the feeding end of the furnace body 4 .

[0034] The pushing assembly includes a hydraulic cylinder 7 and a pushing plate 701 . The pushing plate 701 is fixedly connected to the driving end of the hydraulic cylinder 7 . The pushing plate 701 abuts against the steel billet 401 on the first conveyor belt 301 .

[0035] The first conveyor belt 301 is connected to a first rotating roller 3011 and a first driving motor 3 , and a driving end of the first driving motor 3 is connected to the first rotating roller 3011 via a belt.

[0036] The second conveyor belt 1 is connected to a second rotating roller 101 and a second driving motor 2 , and a driving end of the second driving motor 2 is connected to the second rotating roller 101 via a belt.

[0037] The push plate 701 is fixedly connected with a guide rod 5 , the support plate 6 is fixedly connected with a guide seat 601 , and the guide rod 5 and the guide seat 601 are slidably connected.

[0038] Reference Figure 1 By sliding the guide rod 5 on the guide seat 601 , the position of the push plate 701 can be limited to prevent the push plate 701 from tilting, thereby improving the stable pushing of the steel billet 401 .

[0039] During use of the utility model, the steel billet 401 to be processed is placed on the first conveyor belt 301, and the first driving motor 3 drives the plurality of first rotating rollers 3011 to rotate. At this time, the steel billet 401 on the first conveyor belt 301 will move along the first conveyor belt 301. After moving a certain distance, the first conveyor belt 301 will transport the steel billet 401 to the front end of the feed port of the furnace body 4, and then the hydraulic cylinder 7 is started. The hydraulic cylinder 7 will push the push plate 701 connected to its driving end to move, and the movement of the push plate 701 will push the first conveyor belt 301. The steel billet 401 on the feeding rack 4011 will be pushed and the steel billet 401 will be pushed to the feeding rack 4011. As the number of steel billets 401 on the feeding rack 4011 gradually increases, the steel billet 401 will be pushed into the furnace body 4. The steel billet 401 transported to the furnace body 4 will be heated by the furnace body 4. The four groups of furnace bodies 4 can simultaneously heat the steel billet 401 for a long time, so that the temperature of the surface of the steel billet 401 can be effectively heated to the core. The core surface temperature of the steel billet 401 is basically the same when the billet is taken out, which solves the problem of large temperature difference between the core surface of the steel billet in the longitudinal walking heating furnace.

[0040] The heated steel billet 401 will be pushed onto the second conveyor belt 1 , and the second driving motor 2 will drive the second rotating roller 101 to rotate, thereby driving the steel billet 401 on the second conveyor belt 1 to move, and then output the processed steel billet 401 .

[0041] By setting the device to a horizontal push feeding mode, the space occupied by the device can be reduced. The four furnace bodies 4 in the device can heat the steel billet 401 continuously for a long time, so that the temperature of the surface of the steel billet 401 can be effectively transmitted to the core. When the billet is discharged, the core surface temperature of the steel billet 401 is basically the same, which solves the problem of large temperature difference between the core surface of the steel billet in the longitudinal walking heating furnace, reduces heat loss, reduces energy consumption, and reduces production costs.

[0042] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
