Abstract
The utility model discloses a heating furnace for heat treatment of a core rod, which is featured by improving the quality of quenching heat treatment of the core rod. The heating furnace for heat treatment of core rod comprises a furnace cover body and a furnace platform arranged in the furnace cover body. The furnace cover body is arranged horizontally and is formed by a front furnace cover anda back furnace cover that are movably abutted. When the core rod is heated, the front furnace cover and the back furnace cover are separated, and the core rod is hung into the furnace platform horizontally, then, the front furnace cover and the back furnace cover are integrally abutted after hanging, and then the core rod is heated. The means can obviously heat each section of the core rod at thesame time and can make the core rod be uniformly heated; the means also improves the heating quality, thereby improving the quality of the quenched core rod; in particular, the heating furnace is suitable for quenching treatment of core rod.
Description
Technical field
The utility model relates to a kind of Equipment for Heating Processing, especially relates to a kind of plug thermal treatment process furnace.
Background technology
At present, existing cored hardening stove adopts pit furnace or controlled atmosphere generator, and these two kinds of bodies of heater are vertical placement.In cored hardening when heating,, an end of plug is introduced into burner hearth, and like this, being heated of plug is the end heating earlier that is introduced into, and the part that then enters is post-heating then, causes the plug inequality of being heated, and influences heating quality, thereby influences the quenching quality of plug.Equally, when plug was come out of the stove, the inhomogeneous cooling that the mandrel segment of coming out of the stove earlier is suffered also will influence the quenching quality of plug.And existing body of heater temperature inside is whole control, but because body of heater is longer, when its inner each section temperature is inconsistent, is difficult for regulating, and also influences the quenching quality of plug easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of plug thermal treatment process furnace that improves the cored hardening thermal treatment quality.
The technical scheme that its technical problem that solves the utility model adopts is: plug thermal treatment process furnace, comprise the bonnet body and be arranged on the intravital table of bonnet, it is characterized in that: described bonnet body is horizontally disposed and formed by movable butt joint of leading portion bonnet and back segment bonnet.
Further be, be respectively arranged with a plurality of warm areas that independently heat in leading portion bonnet and the back segment bonnet, in each heating warm area, be provided with well heater and temperature sensor.
Further be to be furnished with the oven door sealing structure between leading portion bonnet and the back segment bonnet.
Further be between bonnet body and table, to be provided with the pneumostop device.
The beneficial effects of the utility model are: when the heating plug, leading portion bonnet and back segment bonnet can be separated, then the plug level be hung on the table, after lifting is finished, the leading portion bonnet be docked the formation one with the back segment bonnet, and then plug is heated.This mode obviously can make each section of plug be heated simultaneously, makes being heated evenly of plug, and improves heating quality, thereby has also just improved the quality after the cored hardening, is particluarly suitable for cored hardening and promotes the use of in handling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side-view of Fig. 1.
Be labeled as among the figure: leading portion bonnet 1, back segment bonnet 2, table 3, well heater 4, temperature sensor 5, oven door sealing structure 6, pneumostop device 7.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1 and shown in Figure 2, plug thermal treatment process furnace of the present utility model comprises the bonnet body and is arranged on the intravital table 3 of bonnet, and described bonnet body is horizontally disposed and formed by leading portion bonnet 1 and back segment bonnet 2 movable butt joints.Then when the heating plug, leading portion bonnet 1 and back segment bonnet 2 can be separated, then the plug level be hung on the table, after lifting is finished, leading portion bonnet 1 be docked the formation one with back segment bonnet 2, and then plug is heated.This mode obviously can make each section of plug be heated simultaneously, makes being heated evenly of plug, and improves heating quality, thereby has also just improved the quality after the cored hardening.
In the process of plug heating, regulate the temperature of the inner different zones of bonnet body for convenience, be respectively arranged with a plurality of warm areas that independently heat in leading portion bonnet 1 and the back segment bonnet 2, in each heating warm area, be provided with well heater 4 and temperature sensor 5.Promptly detect each regional temperature value by temperature sensor 5, itself and the temperature of setting are compared, if the temperature of certain heating warm area is higher than design temperature, then regulate well heater 4 coolings, make it consistent, if the temperature of certain heating warm area is lower than design temperature with design temperature, then regulating well heater 4 heats up, thereby make that bonnet body temperature inside is constant, guarantee that plug integral body is heated evenly, and obviously can improve the quenching heating quality of plug.
When heating short plug, plug only can be placed on leading portion bonnet 1 or back segment bonnet 2 interior getting final product, at this moment, leading portion bonnet 1 and back segment bonnet 2 need not dock.But,, be furnished with oven door sealing structure 6 between leading portion bonnet 1 and the back segment bonnet 2 for sealing this opening because the joint of leading portion bonnet 1, back segment bonnet 2 has opening.Then when only adopting leading portion bonnet 1 or back segment bonnet 2 heating weak point plugs, can utilize oven door sealing structure 6 that the butt joint end opening part of leading portion bonnet 1 or back segment bonnet 2 is sealed, guarantee the stability of the inner Heating temperature of bonnet body, improve the heating quality of this weak point plug.And when needs dock the back as the use of the long plug of heating with leading portion bonnet 1 with back segment bonnet 2, oven door sealing structure 6 removed from the butt joint end opening part of leading portion bonnet 1 or back segment bonnet 2 get final product.
For ease of the sealing between bonnet body and the table 3, between bonnet body and table 3, be provided with pneumostop device 7.Then in the process that leading portion bonnet 1 and back segment bonnet 2 are opened and moved, the pneumavalve of pneumostop device 7 is opened automatically; When present segment bonnet 1 puts in place with back segment bonnet 2 closures, the pneumavalve of pneumostop device 7 cuts out automatically, forming sealing between bonnet body and the table 3 (as can on this pneumostop device 7, the shutoff fiber being set, when pneumavalve cuts out, this shutoff fiber just is sealed between bonnet body and the table 3), guarantee when heating the bonnet body and table 3 between stopping property.
Claims (4)
