Description
Technical field
The utility model relates to a kind of conticaster, especially a kind of caster two cold chamber.
Background technology
At present, the inner arc side of the opening operated by rotary motion Er cold house of two cold steaming discharge pipes of conticaster Zhong Er cold house, makes the steaming discharge pipe opening of two cold houses lower, because steam moves upward, thereby makes the steam of two cold houses cannot emptying.The two steam rows of cold house are unclean, when environment temperature is slightly low, there will be continuous casting platform is all steam, make continuous casting vibrating hydraulic cylinder and liquid level detection line for a long time in the environment in high-temperature steam, meanwhile, because steam fills the air, water steel loop border high humidity, affect the quality of continuous casting raw and auxiliary material, thereby have a strong impact on product quality.In addition, cooling water and steam cannot be recycled, and is also problem demanding prompt solution.
Summary of the invention
The technical problems to be solved in the utility model, is exactly for the existing deficiency of prior art, and a kind of caster two cold chamber is provided, and the steam in Gai Er cold house can emptying, and the steam of discharging in cooling water He Er cold house can be recycled.
This programme is achieved by the following technical measures: this caster two cold chamber comprises two cold house's bodies and is arranged at the supporting deflector roll in two cold houses, described two cold house's bodies are from up to down evenly provided with at least two inlet scoops, described inlet scoop is connected with blower fan by carrier pipe, described blower fan is connected with heat exchanger by carrier pipe, on the carrier pipe between described blower fan and heat exchanger, is provided with steam-flow meter; Between vertically adjacent two supporting deflector rolls, correspondence is provided with cooling jet, and in cooling jet, the cooling jet of the top is oval nozzle, the cooling jet of below is flat burner; Described supporting deflector roll below is provided with cooling water feeder, described cooling water feeder is connected with cooling tower by carrier pipe, described cooling tower is connected with water tank by carrier pipe, throughput direction along cooling water on carrier pipe between described water tank and cooling tower is disposed with temperature sensor and filter, described water tank is connected with total carrier pipe, on total carrier pipe, the pump housing is installed, total carrier pipe is connected with each cooling jet by a minute carrier pipe in parallel.
On above-mentioned minute carrier pipe, be provided with control valve, by control valve, regulate the conveying capacity of each minute carrier pipe.
Cooling jet between cooling jet is oval nozzle or flat burner at the top cooling jet and, can to the concrete needs of cooling water, select flexibly according to different size steel billet, if need cooling water inflow greatly just to adopt oval nozzle, need the little flat burner that just adopts of cooling water inflow.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this caster two cold chamber, (1) two cold house's body is from up to down evenly provided with at least two inlet scoops, compared with prior art so thoroughly the steam in Jiang Er cold house get rid of, avoided because steam fills the air, making to water steel loop border high humidity in prior art, thereby avoided affecting quality and the product quality of continuous casting raw and auxiliary material owing to watering steel loop border high humidity.Steam in (two) two cold houses enters heat exchanger by blower fan and carrier pipe and carries out heat exchange, to make full use of the waste heat of steam, effectively saves the energy; (3) shape of cooling jet is distinguished setting according to diverse location to the demand difference of cooling water, specifically, the cooling water of upper support deflector roll needs required amount large, the cooling water on top is finally pooled to bottom, so the injection flow rate of lower nozzle is little, also can meet the demands, accordingly, in cooling jet, the cooling jet of the top adopts oval nozzle, the cooling jet of below adopts flat burner, because the price of the more oval nozzle of flat burner is low, can reduce production costs like this; (4) cooling water finally can be pooled in cooling water feeder, after the filtration of and the filter cooling through cooling tower of the cooling water in cooling water feeder, can get back in cooling water water tank and reuse again, can save production cost.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
In figure, 1-Er cold house body, 2-cooling jet, 3-blower fan, 4-steam-flow meter, 5-carrier pipe, 6-heat exchanger, 7-control valve, 8-divides carrier pipe, the 9-pump housing, the total carrier pipe of 10-, 11-water tank, 12-carrier pipe, 13-filter, 14-temperature sensor, 15-cooling tower, 16-cooling water feeder, 17-supports deflector roll, 18-cooling jet, 19-cooling jet.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of caster two cold chamber, as shown in the figure, it comprises two cold house's bodies 1 and is arranged at the supporting deflector roll 17 in two cold house's bodies 1, on described two cold house's bodies 1, be from up to down evenly provided with at least two inlet scoops, each inlet scoop is connected with blower fan 3 by carrier pipe 5, described blower fan 3 is connected with heat exchanger 6 by carrier pipe 5, on carrier pipe between described blower fan 3 and heat exchanger 6,5 are provided with steam-flow meter 4, blower fan 3 is by the steam sucking-off fully in Jiang Er cold house, each inlet scoop body 1, the steam of two cold house's body 1 interior discharges is entered and in heat exchanger 6, is carried out heat exchange by carrier pipe 5 and blower fan 3, to utilize fully the waste heat of steam.
Between two vertically adjacent supporting deflector rolls 17, correspondence is provided with cooling jet 2, cooling jet 18 and cooling jet 19, the cooling jet 2 that is positioned at the top is for oval nozzle, the cooling jet 19 of below is flat burner, and the cooling jet 18 between cooling jet 19 is oval nozzle or flat burner at the top cooling jet 2 and.The shape of cooling jet 2, cooling jet 18 and cooling jet 19 is distinguished setting according to diverse location to the demand of cooling water is different, specifically, 17 pairs of cooling waters of upper support deflector roll need required amount large, so the cooling jet 2 of the top adopts oval nozzle, the cooling water on top is finally pooled to bottom, so the injection flow rate of bottom cooling jet 19 is little, also can meet the demands, so, the cooling jet 19 of below adopts flat burners, because the price of the more oval nozzle of flat burner is low, can reduce production costs like this.
Supporting deflector roll 17 belows are provided with cooling water feeder 16, described cooling water feeder 16 is connected with cooling tower 15 by carrier pipe 12, described cooling tower 15 is connected with water tank 11 by carrier pipe 12, throughput direction along cooling water on carrier pipe 12 between described water tank 11 and cooling tower 15 is disposed with temperature sensor 14 and filter 13, described water tank 11 is connected with total carrier pipe 10, on total carrier pipe 10, the pump housing 9 is installed, total carrier pipe 10 is by minute carrier pipe 8 and cooling jet 2 in parallel, cooling jet 18 is connected with cooling jet 19, divide on carrier pipe 8 and be provided with control valve 7.Cooling water finally can be pooled in cooling water feeder 16, after the filtration of and the filter 13 cooling through cooling tower 15 of the cooling water in cooling water feeder 16, is back in water tank 11 and reuses, and can save production cost.
In the utility model, without the technical characterictic of describing, can pass through existing techniques in realizing, not repeat them here.The foregoing is only preferred embodiment of the present utility model; the utility model is not limited in the above-mentioned specific embodiment; the variation that those of ordinary skills make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
