Description
Technical Field
The utility model relates to an install water-cooled fire blocking sealing curtain at roller bottom formula heating furnace dress discharge gate belongs to the heating technology field.
Background
The charging and discharging ports of the roller-hearth heating furnace for continuous steel charging production are all provided with fire-blocking sealing curtains, the traditional fire-blocking sealing curtains are stainless steel wire woven curtains generally, the wire diameter is generally smaller than 2mm due to the limitation of a weaving process, and the wire diameter is too large to be processed and manufactured. Because the steel wires of the woven curtain are thin, the high-temperature oxidation resistance and the abrasion resistance of the woven curtain are weak, and the woven curtain needs to be replaced after being used for about two years. Because the existing sealing curtain adopts an installation mode of integrally embedding into a furnace top, the replacement difficulty is higher, the furnace needs to be stopped for a long time for each replacement, and the influence on production is larger, so that the improvement is necessary.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a long service life, easy dismounting's roller-hearth heating furnace charge and discharge gate's fire-stopping sealing curtain to the drawback of prior art to ensure going on smoothly of production.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a sealed curtain of keeping off fire of roller hearth heating furnace dress discharge gate, includes water-cooling axle and many stainless steel chains in the constitution, the outside top at roller hearth heating furnace dress discharge gate is placed to water-cooling axle level, and the furnace mouth body fixed connection of support frame and roller hearth heating furnace is passed through at the both ends of water-cooling axle, and many stainless steel chains hang at water-cooling epaxial and along the length direction align to grid of water-cooling axle.
According to the fire-blocking sealing curtain for the charging and discharging port of the roller-hearth heating furnace, the water-cooling shaft is a hollow shaft, and two ends of the water-cooling shaft are connected with the circulating cooling water pipe through flanges.
According to the fire-stopping sealing curtain of the charging and discharging port of the roller-hearth heating furnace, the stainless steel chains are hung on the water-cooling shaft through the hanging rings, the hanging rings are loosely sleeved on the water-cooling shaft and are uniformly arranged along the length direction of the water-cooling shaft, and the upper end of each stainless steel chain is fixed on the corresponding hanging ring.
The fire-blocking sealing curtain of the charging and discharging port of the roller-hearth heating furnace is characterized in that two stainless steel chains are hung on each hanging ring.
The fire-blocking sealing curtain of the charging and discharging port of the roller-hearth heating furnace is characterized in that the stainless steel chain is a ring chain.
The utility model discloses mainly constitute by the stainless steel chain of close packing, not only have and weave the same fire-stopping function of curtain with traditional steel wire, the manufacturing process does not have the restriction in the aspect of the materials specification moreover, can effectively prolong the life of the sealed curtain of fire-stopping. In addition, because this keep off fire sealing curtain installs in the outside of dress discharge gate, greatly reduced the change degree of difficulty, shortened the change time, ensured going on smoothly of production.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic hanging view of a stainless steel chain.
The reference numbers in the figures are as follows: 1. the furnace mouth comprises a furnace mouth body, 2, a water-cooling shaft, 3, a hanging ring, 4, a support frame, 5 and a stainless steel chain.
Detailed Description
The utility model provides a water-cooled fire-blocking sealing curtain for fire blocking at a charging and discharging port of a continuous steel charging production roller-hearth heating furnace, which adopts an externally-hung installation mode and can be replaced on line, compared with the traditional embedded installation mode, the replacement is convenient and fast, and the operation can be realized only by blowing out the furnace for a short time and cooling; the sealing curtain body is made of double-layer stainless steel chain rings, is not limited by the wire diameter, is high in strength, good in wear resistance and long in service life, can be replaced under the wire for any chain according to different degrees of wear, and reduces cost investment.
Referring to fig. 1 and 2, the utility model mainly comprises a water-cooling shaft 2, a hanging ring 3, a support frame 4 and a stainless steel chain 5. Double-layer stainless steel chains 5 are hung on a water-cooling shaft 2 through hanging rings 3 at certain intervals, and the water-cooling shaft 2 is installed on a charging and discharging furnace mouth of the roller hearth type heating furnace through a support frame 4 welded on a steel structure of a furnace mouth body 1. Circulating cooling water is introduced into the water-cooling shaft 2, so that the heat-resistant strength of the water-cooling shaft is improved, and the influence of high temperature is not required to be considered; two ends of the water-cooling shaft 2 are provided with quick dismounting flange joints to realize online quick replacement; the double-layer stainless steel chain 5 is made of stainless steel chain rings, is not influenced by the thickness of the braided wire, and achieves the purposes of improving the high-temperature wear resistance and prolonging the service life by improving the diameter. The double-layer stainless steel chain 5 can be replaced individually according to different abrasion degrees under the wire, so that the use cost is reduced.
The utility model has the characteristics of simple structure, manufacturing simple to operate, vulnerable position are removable, use cost low grade. The problems of short service life, high replacement difficulty and high production influence of the traditional embedded sealing curtain of the charging and discharging furnace mouth of the continuous production roller-hearth heating furnace are solved.
