Abstract
The utility model discloses a device for sealing the outlet of a cold-rolled silicon steel normalizing scouring annealing furnace and the device is applicable to horizontal-type continuous annealing line of silicon steel, tin-coated steel and carbon steel. The device comprises a box body which comprises a lower box body and an upper box body. Two heat-resisting rollers are arranged at the middle part of the box body. Refractory bricks are adopted to build the lower box body, the upper box body is made of refractory fiber and the front and back of two heat-resisting rollers are respectively sealed by sealing curtains. The device has the advantages of simple structure, small size and volume, good sealing performance and convenience in installation, use and maintenance. Meantime, water leakage caused by the sealing device is avoided and the failure shut-down time is shortened.
Description
Technical field:
The utility model belongs to the off-set facility that cold rolled silicon steel is produced, and is specifically related to a kind of cold rolled silicon steel normalizing pickling lehre exit seal device.
Background technology:
In the normalizing pickling is produced,, regularly change circle shear and scrap cutter cutting edge according to the assurance of technological process of production requirement and quality product; And every month once equipment decide inspection, at this moment lehre can not stop fully, is incubated at a certain temperature; The heat of taking out of through the exit seal device along with the band steel will reduce greatly; The exit seal device will sharply cool off, in cycling start, and the motion of band steel; The heat that steel band going along with goes out increases again thereupon; The exit seal device will be rapidly heated, and the exit seal device will will deform under this effect of expanding with heat and contract with cold fast and cause leaking, and particularly winter, this situation will seem obvious more.
What existing exit seal device adopted is the water jacket form, the effect that casing is subject to expand with heat and contract with cold and deforming, even crackle appears, and cause leaking, cause the resistive band short circuit.
Summary of the invention:
It is simple in structure, not yielding that the purpose of the utility model is to provide, and stopping property is better, safe and reliable a kind of cold rolled silicon steel normalizing pickling lehre exit seal device.
The utility model comprises casing, it is characterized in that casing is made up of lower box and upper box, is provided with two heat-resistant rolls at the intravital middle part of case, and lower box adopts refractory brick to build by laying bricks or stones, and upper box adopts refractory fibre to process, and seals with sealing curtain respectively before and after two heat-resisting rods.
The utility model is simple in structure, overall volume is little, good airproof performance, and installation, use, easy to maintenance have stopped to have shortened the scram time because of tightness system leaks simultaneously.
The utility model is applicable to the horizontal continuous annealing line of silicon steel, tin-coated steel, carbon steel.
Description of drawings:
Fig. 1 is the structure iron of the utility model embodiment.
Among the figure, 1, shell, 2, upper box, 3, lower box, 4, heat-resistant roll.
Embodiment:
Embodiment: shown in Figure 1, present embodiment comprises casing, and casing is made up of lower box 3 and upper box 2, is provided with 4, two heat-resistant rolls 4 of two heat-resistant rolls at the intravital middle part of case and is used for the support belt steel, avoids being with steel to contact with casing; Lower box 3 adopts refractory brick to build by laying bricks or stones, and upper box 2 adopts refractory fibre to process, and lower box 3 is surrounded by metal shell with upper box 2 peripheries, respectively with the sealing curtain sealing, forms sealing chamber before and after two heat-resisting rods, feeds nitrogen in the sealing chamber.
