Abstract
The utility model discloses a furnace door structure for a car-type heat treatment furnace. The furnace door structure comprise a furnace door main body, a plurality of evenly-distributed small U-shaped steel strips are installed on the surface of the furnace door main body along the longitudinal direction, a small U-shaped steel strip is installed in the horizontal center of the surface of the furnace door main body, a large U-shaped steel strip is respectively arranged on two sides of the horizontally-arranged small U-shaped steel strip, and two ends of all small U-shaped steel strips and large U-shaped steel strip are fixed at the edge of the furnace door main body. The furnace door structure has the advantages that the small U-shaped steel strips and the large U-shaped steel strips have the radiation function, temperature of the small U-shaped steel strips and the large U-shaped steel strips arranged on the outer surface of the furnace door main body is low so as to enable tolerance of the furnace door structure to be high, the high-temperature furnace door main body can be supported, and tolerance of the furnace door structure can be improved wholly.
Description
Technical field
The utility model relates to a kind of door structure, is the necessary stationary installation of fire door of car-type heat treating furnace.
Background technology
Heat treatment furnace is the general designation of metal works being carried out the industrial furnace of various metal heat treatmets.Heat treatment furnace can adopt the type of furnace of various process furnace, but requires more strictly to control furnace temperature and furnace atmosphere etc.The most using gas fuel heating of heat treatment furnace, in order accurately to control furnace temperature, the heat treatment furnace that has is used electrically heated.Modern thermal treatment (particularly thermo-chemical treatment) technology is increasingly sophisticated, and the form of heat treatment furnace is also a lot.For successive thermal treatment flow process, must be equipped with suitable continuous heat treating furnace; For cycling thermal treatment process, operating machine and the robotization that adopt the CA controlled atmosphere of pump circulation and make stove.
Like the patent No. 200720040085 disclosed a kind of heat treatment furnace structures, purpose provides the less heat treatment furnace of a kind of floor space.It comprises solid solution stove, the aging oven that is provided with roller bar type e Foerderanlage; Quenching tank; And material is transported to the grass-hopper of aging oven from the solid solution stove through quenching tank, solid solution stove, aging oven are arranged up and down, and liftable grass-hopper is set below the end of solid solution stove; On the bottom surface of the solid solution stove above the grass-hopper, have with bottom surface and become the split type movable discharge door that is connected; The below of grass-hopper is a quenching tank; One side of quenching tank is an aging oven; Roller bar type e Foerderanlage is set on grass-hopper, and the roller rod on grass-hopper, solid solution stove, the aging oven parallels.
The fire door of prior art heat treatment furnace in the process of being heated owing to receive bigger pulling force; But high temperature itself can make the various tolerance degradation of fire door material, so the stability of door structure is the technical problem that the prior art heat treatment furnace does not have fine solution always.
The utility model content
The purpose of the utility model provides a kind of door structure of car-type heat treating furnace, the fire door that solves the prior art heat treatment furnace problem of rear stability of being heated.
The purpose of the utility model is to realize through following technical scheme:
The door structure of car-type heat treating furnace; Comprise oven door body; On the surface of oven door body the little U section steel bar that several are evenly arranged is installed vertically; Transverse center on the surface of oven door body is equipped with a little U section steel bar, in the both sides of the said little U section steel bar of laterally installing a large U type steel bar is installed respectively.
The two ends of each said little U section steel bar and said large U type steel bar are fixed on the edge of oven door body.
The beneficial effect of the utility model is; Through little U section steel bar and large U type steel bar are set, can play the effect of heat radiation on the one hand, on the other hand because these structures are positioned at the outside surface of oven door body; Temperature is lower; So the tolerance performance is just higher, can play the effect of support to the pyritous oven door body, so improved the tolerance performance of door structure on the whole.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the front view of the door structure of the described car-type heat treating furnace of the utility model embodiment.
Embodiment
As shown in Figure 1; The door structure of the described car-type heat treating furnace of the utility model embodiment; Comprise oven door body 1; The surface of oven door body 1 the little U section steel bar 2 that several are evenly arranged vertically is installed, the transverse center on the surface of oven door body is equipped with a little U section steel bar 2, in the both sides of the said little U section steel bar 2 of laterally installing a large U type steel bar 3 is installed respectively.
The two ends of each said little U section steel bar 2 and said large U type steel bar 3 are fixed on the edge of oven door body 1.
The beneficial effect of the utility model is; Through little U section steel bar 2 and large U type steel bar 3 are set, can play the effect of heat radiation on the one hand, on the other hand because these structures are positioned at the outside surface of oven door body; Temperature is lower; So the tolerance performance is just higher, can play the effect of support to the pyritous oven door body, so improved the tolerance performance of door structure on the whole.
Claims (1)
1. the door structure of car-type heat treating furnace; Comprise oven door body, it is characterized in that, the little U section steel bar that several are evenly arranged vertically is installed on the surface of oven door body; Transverse center on the surface of oven door body is equipped with a little U section steel bar; Both sides in the said little U section steel bar of laterally installing are installed a large U type steel bar respectively, and the two ends of each said little U section steel bar and said large U type steel bar are fixed on the edge of oven door body, and the quantity of little U section steel bar is 1-10.
