Description
Technical field
The utility model is a kind of refrigerating unit, and particularly a kind of euphotic zone steel continuous annealing refrigerating unit belongs to the metallurgy rolling technical field.
Background technology
Cold rolled strip of the prior art can cause the inner defectives such as bigger internal stress and internal fissure that exist of band steel after the rate that presses down the greatly processing of cold-rolling process.By recrystallization annealing, can eliminate cold rolling work hardening, improve moulding and toughness, remove unrelieved stress, and eliminate the partial interior defective.
The tradition annealing process be because need heat and be incubated to the band steel, usually causes the band steel secondary oxidation at high temperature behind the pickling descaling, and the surface luster of steel is with in forfeiture, even produces oxide skin again.
For addressing the above problem, produced technology such as annealing furnace by the reducing gas protection, guarantee with steel not oxidized under the high temperature of annealing process with anaerobic or reducing atmosphere.Even if but in reducing atmosphere, the high temperature of annealing process still can cause the emulsion of steel strip surface when cold rolling and ROLLING OIL carbonization to decompose, and produces " black-tape " defective of belt steel surface.
Be to remove the emulsion and the ROLLING OIL of steel strip surface, often need before annealing, increase off-line or online degreasing system, or the emitted dose of increasing shielding gas causes the serious waste of the energy and shielding gas to blow emulsion and ROLLING OIL off.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art; provide a kind of and be difficult to avoid " black-tape " defective in order to overcome traditional technology; and waste energy and the problem of shielding gas; a kind of euphotic zone steel continuous annealing refrigerating unit; separate a plurality of independently cooling rooms by sealed roller; and in each cooling room, adopt different process for cooling, with the cooling and the heat insulation effect of raising continuous annealing, and realize the effect energy-conservation and loss of minimizing shielding gas.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of euphotic zone steel continuous annealing refrigerating unit, comprise the band steel, the band steel is by the continuous annealing refrigerating unit, the continuous annealing refrigerating unit comprises at least two cooling rooms, sealed roller, conveying roller, gas pipeline system, gas jet and interchanger, described cooling room comprises upper plenum and following cavity, be provided with the band steel between upper plenum and following cavity, the end of upper plenum and following cavity is provided with sealed roller, be provided with conveying roller between described sealed roller, sealed roller and conveying roller contact with the band steel, and gas pipeline system is provided with gas jet by cooling room in the gas pipeline system, gas jet is corresponding with the band steel, is provided with interchanger between described gas pipeline system.The band steel through pickling, cold rolling, annealing, the heating, the insulation after, enter refrigerating work procedure.Cool furnace of the present utility model is by high-speed gas injection cooling down high-temperature band steel; and cool furnace is divided into a plurality of independently cooling rooms by interior partition wall and sealed roller; be equipped with independently cooling gas nozzle and gas pipeline system in each cooling room; make the cold rolled strip steel production merchant can adjust composition, flow and the flow velocity of each cooling room internal cooling gas respectively at the cold rolled strip of different size and unlike material; to optimize the annealing process for cooling as far as possible; improve the quality of products; and reduce cost, reduce the loss of the energy and shielding gas.Because the band steel is in temperature-fall period, temperature reduces gradually, so the in the past shielding gas that extracts in the road cooling room can be used for the cooling gas of road cooling room after the preheating.Effectively utilize refrigerative used heat, significantly cut down the consumption of energy, before cool furnace, add the degreasing system, to improve the effect of removing emulsion and ROLLING OIL.
As preferably, have three cooling rooms in the continuous annealing refrigerating unit at least, pass through inwall separately between described cooling room.
As preferably, described conveying roller is evenly distributed in the back side of band steel, and described gas pipeline system is located in the upper plenum.
Therefore, a kind of euphotic zone steel continuous annealing refrigerating unit that the utility model provides, simple in structure, improve the quality of products, reduce production costs, significantly cut down the consumption of energy, improve energy utilization rate.
