An outlet of the stainless steel water tank is connected with an inlet of a water supply pump through a stainless steel pipeline. An outlet of the water supply pump is connected with an inlet of a self-washing filter through a stainless steel pipeline. An outlet of the self-washing filter is connected with an electric furnace secondary cooling water nozzle through a stainless steel pipeline. According to the water supply system of the electric furnace secondary cooling water, industrial clear water with stable water quality is used as a water source, the bag type filter and the self-washing filter are used for carrying out secondary filtering on the industrial clear water, the stainless steel tank and the stainless steel pipelines which cannot generate rust are used, accordingly, the water quality of the electric furnace secondary cooling water is greatly improved, the blocking rate of the electric furnace secondary cooling water nozzle is lowered to 1/10 of the original blocking rate, meanwhile, the atomization effect of the electric furnace secondary cooling water nozzle is improved, and therefore the requirement for electric furnace continuous casting billet secondary cooling is met.
Description
Technical field
The present invention relates to Treatment of Industrial Water technical field, be specifically related to the water system of electric furnace secondary cooling water.
Background technology
Electric furnace secondary cooling water cools by carrying out second time to electric furnace continuous casting steel billet after the nozzle atomization of electric furnace secondary cooling water.When the water degradation of electric furnace secondary cooling water, the atomizing effect of electric furnace secondary cooling water nozzle also can be deteriorated, even can cause electric furnace secondary cooling water spray nozzle clogging, thus the second time cooling effect of electric furnace continuous casting steel billet also can be adversely affected, and then affect the quality of electric furnace continuous casting steel billet.
The water system of original electric furnace secondary cooling water is: the turbid ring water cooling pond of continuous casting is connected with the entrance of supply-water pump by pipeline, and water supply delivery side of pump is connected with the entrance of filter, and the outlet of filter is connected with electric furnace secondary cooling water nozzle.The water source that the water system of original electric furnace secondary cooling water is is electric furnace secondary cooling water with the continuous casting turbid circulating water in the turbid ring water cooling pond of continuous casting; it is very unstable that the water quality of continuous casting turbid circulating water is understood the frequent startup-shutdown because of electric furnace continuous casting equipment and be become; thus the instability that the water quality of electric furnace secondary cooling water also can become, will have a negative impact to the second time cooling of electric furnace continuous casting steel billet like this.
Summary of the invention
Technical problem to be solved by this invention is: will provide a kind of water system that water quality can be made to become excellent and stable electric furnace secondary cooling water.
In order to solve the problem, the technical solution adopted in the present invention is: the water system of electric furnace secondary cooling water, be characterized in: industrial fresh water pipeline is connected with the entrance of bag filter, the outlet of bag filter is connected with the water inlet of stainless steel water tank by stainless steel pipes, the delivery port of stainless steel water tank is connected with the entrance of supply-water pump by stainless steel pipes, water supply delivery side of pump is connected with the entrance of self-cleaning filter by stainless steel pipes, and the outlet of self-cleaning filter is connected with electric furnace secondary cooling water nozzle by stainless steel pipes.
Further, the water system of aforesaid electric furnace secondary cooling water, wherein: in bag filter, filter bag aperture is 45 ~ 55um.
Further, the water system of aforesaid electric furnace secondary cooling water, wherein: the filtering accuracy of self-cleaning filter is 45 ~ 55um.
Further, the water system of aforesaid electric furnace secondary cooling water, wherein: the water inlet of stainless steel water tank and delivery port are all positioned at the top of stainless steel water tank.
Further, the water system of aforesaid electric furnace secondary cooling water, wherein: supply-water pump is multistage supply-water pump, lift is 130 ~ 150m, and be preferably 142m, flow is 18 ~ 22m
3/ h, is preferably 20m
3/ h.
Advantage of the present invention is: the water system of this electric furnace secondary cooling water can make the water quality of electric furnace secondary cooling water become excellent and stable, thus the atomizing effect of electric furnace secondary cooling water nozzle is improved, and then improves the second time cooling effect of electric furnace continuous casting steel billet.
Accompanying drawing explanation
Fig. 1 is the water system of electric furnace secondary cooling water of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail.
The water system of electric furnace secondary cooling water, as shown in Figure 1, industrial fresh water pipeline 1 is connected with the entrance of bag filter 2, and bag filter 2 can filter out the iron rust particle produced because of corrosive pipeline in industrial clear water; The outlet of bag filter 2 is connected with the water inlet 3 of stainless steel water tank 4 by stainless steel pipes, the delivery port 5 of stainless steel water tank 4 is connected by the entrance of stainless steel pipes with supply-water pump 6, arranging stainless steel water tank 4 one aspect is in order to retaining, thus meet the water supply requirement of supply-water pump 6, to make industrial clear water precipitated impurities in stainless steel water tank 4 on the other hand, thus purify water, when the impurity of precipitation is many in stainless steel water tank 4, blowdown cleaning can be carried out to stainless steel water tank 4 by hand; The outlet of supply-water pump 6 is connected by the entrance of stainless steel pipes with self-cleaning filter 8, and self-cleaning filter 8 can utilize filter screen wherein directly to tackle impurity in water, thus can reduce turbidity, purifies water; The outlet of self-cleaning filter 8 is connected with electric furnace secondary cooling water nozzle 10 by stainless steel pipes.In the present embodiment, employ stainless steel water tank 4 and stainless steel pipes, arranging like this is produce iron rust particle after preventing water tank and pipeline to be corroded.
In the present embodiment, in bag filter 2, filter bag aperture is 45 ~ 55um, and the filtering accuracy of self-cleaning filter 8 is 45 ~ 55um.The water inlet 3 of stainless steel water tank 4 and delivery port 5 are all positioned at the top of stainless steel water tank 4, and arranging like this is to make stainless steel water tank 4 precipitate more impurity, extend water tank clearance time.In addition, supply-water pump is multistage supply-water pump, and lift is 130 ~ 150m, and be preferably 142m, flow is 18 ~ 22m
3/ h, is preferably 20m
3/ h.Such setting is the atomizing effect in order to ensure electric furnace secondary cooling water nozzle, if water supply pump lift and flow do not reach above-mentioned requirements, the atomizing effect of electric furnace secondary cooling water nozzle can be caused to be deteriorated.
Beneficial effect of the present invention is: the water system of this electric furnace secondary cooling water be with water-quality ratio more industrial clear water for water source, and employ bag filter and self-cleaning filter has carried out secondary filter to industrial clear water, and employ the stainless steel water tank and stainless steel pipes that can not produce iron rust, thus substantially increase the water quality of electric furnace secondary cooling water, the plugging rate of electric furnace secondary cooling water nozzle is made to be reduced to original 1/10, improve electric furnace secondary cooling water nozzle simultaneously and obtain atomizing effect, thus meet the requirement of electric furnace continuous casting steel billet second time cooling, improve the quality of electric furnace continuous casting steel billet.
