Abstract
The utility model discloses stacked material frame for a kind of annealing furnace, at the bottom of comprising the circular framework and frame of integrally casting moulding, described framework periphery is provided with spiral contraction band, and contraction band is spaced and is formed by plural slotted eye; Described Kuang Di center is provided with siphonostele, and newel top periphery is extended with the crossbeam of the right-angled intersection that connects framework.The utility model is by the beam structure of newel and top periphery thereof, in conjunction with spiral contraction band structure, make to expect that its distortion allowance of process of frame thermal distortion in annealing furnace is larger, prevent crack, and realized the stacked placement of upper and lower two layered material frames, effectively prevent product in the urgent lower layered material frame of upper layer material circle base pressure, when improving Ways of Heat Treatment Product Quality, extended the work-ing life of material frame.
Description
Technical field
The utility model relates to a kind of material frame, specifically stacked material frame for a kind of annealing furnace.
Background technology
Heat treatment furnace is generally divided into annealing furnace, quenching furnance, tempering stove, normalizing furnace, hardening and tempering furnace, is mainly used in the annealing of carbon steel, steel alloy part; The tempering of hard surfacing part is processed.Especially the material frame using in annealing furnace, is to stand for a long time frequent, reciprocal heat, the wearing detail of cooling process, expects that frame, owing to loading a large amount of heat treatment materials, need to appoint and so have good weight-carrying ability under heated condition simultaneously.The material frame of traditional structure mostly adopts the direct integrally casting moulding of resistant to elevated temperatures metallic substance, although it has adopted high temperature material manufacture due to long-term thermal distortion, tends to occur framework surface fracture, the technical failure such as crack.The material frame of traditional structure, is entering the material frame of latter two stacked on top of one another of heat treatment furnace in addition, is positioned at the product of the material frame of lower one deck, and the product that tends to be subject in upper layer material frame is out of shape because material frame thermal distortion tenesmus causes oppressing, and affects quality product.How to solve the problems of the technologies described above is the object that those skilled in the art study always.
Summary of the invention
The utility model provides a kind of simple in structure, long service life, stacked material frame for annealing furnace that supporting capacity is strong.
A stacked material frame for annealing furnace, at the bottom of comprising the circular framework and frame of integrally casting moulding, described framework periphery is provided with spiral contraction band, and contraction band is spaced and is formed by plural slotted eye; Described Kuang Di center is provided with siphonostele, and newel top periphery is extended with the crossbeam of the right-angled intersection that connects framework.This kind of material mount structure is by the beam structure of newel and top periphery thereof, played the good stacked placement of two layered material frames up and down, effectively prevent product in the urgent lower layered material frame of upper layer material circle base pressure, when improving Ways of Heat Treatment Product Quality, extended the work-ing life of material frame.Spiral contraction band structure in addition, make to expect that its distortion allowance of process of frame thermal distortion in annealing furnace is larger, relatively traditional annular retractable band is easy fracture more not, and plural slotted eye arrangement architecture has further expanded distortion allowance, prevents crack.
As the adjoining edge at the bottom of the circular framework of structure optimization and frame, be provided with plural arc notch structure, this kind of arc notch structure is actual acquisition of production based on long-term, in actual production, expect frame occur crack at most, the fastest position is exactly the adjoining edge at the bottom of circular framework and frame, major cause is that the stress is here the most concentrated, and arc notch well-formed's solution problem of stress concentration, prevent that crack from appearring in this place.
Described framework periphery is provided with upper and lower two spiral contraction bands, and the slotted eye of correspondence up and down on two contraction bands, is crisscross arranged each other.The slotted hole structure of friendship anchor setting has further expanded the surplus of thermal distortion mutually, prevents from occurring in the framework between two contraction bands the crack that thermal distortion causes.
Described tubular center's column wall is provided with screw thread, and this kind of screw thread increased impetus after connecting thread cylinder in the material frame process that promotes, takes, and improved the weight capacity of material frame.
The utility model is by the beam structure of newel and top periphery thereof, in conjunction with spiral contraction band structure, make to expect that its distortion allowance of process of frame thermal distortion in annealing furnace is larger, prevent crack, and realized the stacked placement of upper and lower two layered material frames, effectively prevent product in the urgent lower layered material frame of upper layer material circle base pressure, when improving Ways of Heat Treatment Product Quality, extended the work-ing life of material frame.
Accompanying drawing explanation
Be illustrated in figure 1 stacked material frame perspective view for the utility model annealing furnace.
Embodiment
Stacked material frame for annealing furnace as shown in Figure 1, at the bottom of comprising the circular framework 4 and frame of integrally casting moulding, framework 4 peripheries are provided with spiral contraction band, and contraction band is spaced and is formed by plural slotted eye 1; Kuang Di center is provided with siphonostele 6, and newel 6 top peripheries are extended with the crossbeam 5 of the right-angled intersection that connects framework.Siphonostele 6 inwalls are provided with screw thread, by having increased impetus after connecting thread cylinder in the material frame process that promotes, takes, have improved the weight capacity of material frame.Framework 4 peripheries are provided with upper and lower two spiral contraction bands, and the slotted eye 1 of correspondence up and down on two contraction bands, hands over anchor setting each other.
As the circular framework 4 of structure optimization, be provided with plural arc notch 3 with the adjoining edge 2 at the bottom of frame.
