Abstract
The utility model relates to a part for a kiln, in particular to a graphite electrode rebaking tunnel kiln insulating door. The graphite electrode rebaking tunnel kiln insulating door is characterized in that the insulating door comprises a door plate, a door I and a door II which are formed by sealing cushions are respectively arranged at the upper and the lower ends of one side of the door plate, a door beam is fixed at the top end of the door I, the lower end of the door I is connected with the upper end of the door II through a hinge, and sealing corrugated plates are respectively connected on the two sides of the door I and the door II which are positioned at the connecting point of the hinge. The door I and the door II which are manufactured in a split manner are connected through the hinge, the sealing corrugated plates are respectively connected on the two sides of the door I and the door II which are positioned at the connecting point of the hinge, therefore, and the overall height of the insulating door manufactured in a split manner is the same with that of the prior integrally manufactured insulating door, but the amount of deformation of the insulating door is only half as much as that of the prior insulating door, therefore, the utility model has the advantages of reasonable structure, free door opening or closing, reliable actions, good sealing performance, long service life, and the like.
Description
Technical field
The utility model relates to the kiln parts, more particularly, is a kind of graphite electrode after baking tunnel cave isolating door.
Background technology
The electric furnace steel making graphite electrode, it is the after baking operation that very important together operation is arranged in manufacturing process.Blank is after the roasting first time, and its bulk density does not still reach requirement, need be at impregnating pitch under the HTHP.Pitch after soaking is free state in graphite electrode, must carry out roasting under 750～800 ℃ of temperature.Its objective is: first is solidificated in the graphite electrode its a part of charcoal molecule, increases the bulk density of graphite electrode; Second volatilizees away its asphalt volatile constituents, for next procedure lays the first stone.
Existing graphite electrode after baking tunnel cave is the external-burning kiln, require the good leak tightness of kiln, common this kiln furnitures have five sects, the front of the isolating door among five sects is between isolation, the back is in the kiln, usually the temperature low (being no more than 50 ℃) between isolating, and the kiln temperature height, and existing graphite electrode after baking tunnel cave isolating door adopts integral door, the structure that slides up and down in the doorframe of tunnel cave is because before the isolating door, the back temperature difference is big, causes isolating door flexural deformation, make a high door-plate elongation of temperature big, door-plate elongation that temperature is low is little, facts have proved, when surface temperature behind the isolating door rises to〉250 ℃ times, the distortion of isolating door surpasses 30mm, and isolating door is stuck in the doorframe can not slide up and down.Therefore isolating door also just can not close and open, and promptly can't move.
Summary of the invention
Technical problem to be solved of the present utility model is, prior art is improved, and provides rational in infrastructure, and door closes or opens freely, reliable in action, good seal performance, the graphite electrode after baking tunnel cave isolating door of long service life.
Solving the technical scheme that its technical problem adopts is, a kind of graphite electrode after baking tunnel cave isolating door, it is characterized in that: it comprises door-plate, upper and lower side in door-plate one side is equipped with door I and the II that sealing gasket constitutes, be fixed with a beam on door I top, door I lower end is connected through the hinge with door II upper end, all is connected with the sealing corrugated plating in the both sides of the door I that is positioned at hinge connection and door II.
Graphite electrode after baking tunnel cave isolating door of the present utility model is that door I and the II by split production is connected through the hinge, be connected with all in the both sides of the door I that is positioned at hinge connection and door II that the sealing corrugated plating constitutes, compare with existing graphite electrode after baking tunnel cave overall isolation door, the isolating door overall height of the utility model split production is identical with the isolating door height of existing integral manufacturing, but deflection only is 1/2 times of existing isolating door, its deflection only was 15mm when isolating door of the present utility model was 250 ℃, its deflection is 21mm during to 350 ℃, distortion＜the 30mm of isolating door, therefore, have rational in infrastructure, door closes or opens freely, reliable in action, good seal performance, advantages such as long service life.
Description of drawings
Fig. 1 looks schematic diagram for graphite electrode after baking tunnel cave isolating door structure master.
Fig. 2 is the A-A generalized section (under the normal temperature state) of Fig. 1.
Fig. 3 is the A-A generalized section (under the condition of high temperature) of Fig. 1.
Among the figure: 1 door-plate, 2 sealing gaskets, 3 beams, 4 doorframes, 5 sealing corrugated platings, 6 hinges.
The specific embodiment
The utility model is described in further detail to utilize drawings and Examples below.
With reference to Fig. 1～3, graphite electrode after baking tunnel cave isolating door of the present utility model comprises door-plate 1, is equipped with the door I and the II of sealing gasket 2 formations at the upper and lower side of door-plate 1 one sides.Be fixed with a beam 3 on door I top, door-plate 1 lower end of door I is connected by hinge 6 with door-plate 1 upper end of door II, all is connected with sealing corrugated plating 5 at the door-plate 1 of the door I that is positioned at hinge 6 junctions and door-plate 1 both sides of door II.
The door-plate height of existing isolating door is 5240mm, deflection is 30mm when temperature rises to 250 ℃, the door I of the utility model split production is connected by hinge 5 with II, and I is highly equal with II for door, and it is identical with the door-plate height of existing isolating door to connect the back total height, be 5240mm, its deflection only is 15mm when temperature rises to 250 ℃, and its deflection is 21mm during to 350 ℃, does not surpass 30mm, therefore door does not block in doorframe 4, and operation freely up and down.
