Detailed description of the invention
Referring to figs. 1 through Fig. 5 and embodiment, this utility model is described further.
A kind of metallic heat treating furnace, as shown in fig. 1, including body of heater 1 and the heating element heater 2 being arranged in body of heater 1, wherein heating element heater 2 uses electric heating type to add heat pipe, is evenly equipped with several formation continuous print heating regions along body of heater 1 on the import of metal material and Way out.In order to improve the heat treatment efficiency of metallic heat treating furnace, the electric heating type in body of heater adds heat pipe two groups, and in being oppositely arranged up and down in body of heater 1.Upper and lower two groups of heating element heaters 2 form a heating region at the inner chamber of body of heater 1, and the metal material sent in body of heater 1 carries out heat treatment in this region.In heating region near following set of heating element heater 2 position on be provided with material rest area 3, metal material is placed in this region, its bearing of trend from the import of metal material to exporting tiling.
Specifically, owing to heating element heater 2 is fixing at body of heater intracavity, thus its thermal-radiating region is the most basicly stable with temperature, in order to the both ends of the surface up and down preventing the metal material on material rest area 3 are overheated, being arranged to material rest area 3 can be to drive the form of metal material tumbling motion thereon.Material rest area 3 is formed side by side by some rotating rollers 31, the end of every rotating roller 31 is all to there being a driving assembly 32, under the drive driving assembly 32, all of rotating roller 31 does gyration at body of heater 1 along self axis of rotation, metal material on material rest area 3 is moved the most therewith, thus ensure the continuous motion of metal material, prevent hot-spot, and, metal material is after the import of body of heater 1 is placed in rotating roller 31, continuous rolling along with rotating roller 31, metal material is increasingly towards the Way out motion relative with the import of body of heater 1 and finally takes out from the outlet of body of heater 1.
As shown in Fig. 2 to Fig. 3, driving assembly 32 to be made up of some groups of Helical gear Transmission assemblies, its number is arranged corresponding to the number of rotating roller 31, it is ensured that the every corresponding one group of Helical gear Transmission assembly of rotating roller 31.The power source driving the motor of assembly 32 to input it is provided with as it near body of heater 1, the outfan of motor connects the power shaft 323 driving assembly 32, owing to the length of body of heater 1 is longer, in order to prevent the processing difficulties of power shaft 323, it is connected with each other by power shaft 323 segmental machining and with shaft coupling 324, it is ensured that all shaft parts all link with the outfan of motor.Helical gear on power shaft 323 is drivewheel 321, that engage, be directly mounted at rotating roller 31 end is driven pulley 322, gear motion by Helical gear Transmission assembly, the end that the motion of motor is transferred to rotating roller 31 drives the revolution of rotating roller 31 to transport to, metal material in material rest area 3 is constantly moved, it is ensured that it is heated evenly and with the motion of rotating roller 31 to the exit movement of body of heater 1.
As shown in Figure 4; as preferably; protection pipe 21 it is socketed with outside the heating element heater 2 part beyond material rest area 3; the circular tube shaped of hollow made by protection pipe 21 preferably by ceramic material; its Main Function is electricity to add formula heating element heater play support, fixing, heat-blocking action, it is ensured that the freely rotatable space heating element 2 of heating element heater 2 itself is not by external world.
In addition, heating element heater 2 in the present embodiment is electric heating type, thus its heat produced outwards transmits with thermal-radiating form, but, the part only having material rest area 3 in body of heater 1 is heat absorption district, the heat that remainder receives all can scatter and disappear away otherwise, so will produce the waste of heat, in order to solve the problems referred to above in the present embodiment, one layer of silicon-carbon plate 4 it is provided with between the inwall of heating element heater 2 and body of heater 1, silicon-carbon plate 4 is utilized to produce thermal-radiating form after being heated, 2 dozens of heats on silicon-carbon plate 4 of heating element heater are returned in material rest area 3 with thermal-radiating form again, reduce the waste of heat.
As in Fig. 5 further, put conveniently for each element in body of heater 1, thermal wall has been built with refractory brick 5 in both sides on the bearing of trend of material rest area 3, hardware is heated in entering material rest area 3 through thermal wall by heating element heater 2, and silicon-carbon plate 4 is also secured on refractory brick 5.
Silicon-carbon plate 4 is divided into straddle 4-1 and transverse slat 4-2, and installing silicon-carbon plate 4 is will to be overlapped in two thermal wall across 4-1 the most at certain intervals, is then all hidden material rest area 3 with some transverse slat 4-2.
Further, in order to prevent the silicon-carbon plate 4 outside with body of heater 1 from producing the loss of heat with the form of heat exchange, it is cotton that the remainder between silicon-carbon plate 4 and body of heater 1 is provided with some refractory heat-insulatings, to prevent the loss of heat.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
