Production method is cooled down safely using the refractory material of electric-arc furnace of above-mentioned safe cooling system is carried out according to the following steps：
Water in tank 2 is direct cooling water, and the water in cooling tower is indirect cooling water；
First step is to start second circulation pump 19 and first circulation pump 10, and second circulation pump 19 makes direct cooling water in storage
Circulate between pond 2, the water leg 24 of electric arc furnaces 1, the inner tube 4 of heat exchange box 3, first circulation pump 10 makes indirect cooling water exist
Circulate between cooling tower and heat exchange box 3；What directly cooling water was walked in heat exchange box 3 is tube side, and indirect cooling water is in heat exchange
Walked in case 3 is shell side.
Directly cooling water is heated when by water leg 24, then in the inner tube 4 by heat exchange box 3 by inner tube 4 outside
The indirect cooling water in portion is cooled down；Indirect cooling water is heated when by heat exchange box 3, is then cooled in cooling tower；
In the middle of the operation of first step, the first valve 27, the second valve 28, the 3rd valve 33 and diffusion valve 30 are in
Closed mode, staff is by observing the water level in the determination water supply tank 22 of the first transparent pipe 29, the such as water level in water supply tank 22
Less than the 2/3 of 22 height of water supply tank, then open diffusion valve 30 and the 3rd valve 33, make elevated tank 21 by the 8th pipeline 32 to
In water supply tank 22, moisturizing is filled it up with until water supply tank 22, turns off diffusion valve 30 and the 3rd valve 33；If in elevated tank 21
Water level less than 21 height of elevated tank 2/3, then open small pump 23, to 21 moisturizing of elevated tank until 21 quilt of elevated tank
Fill it up with, turn off small pump 23；The water level in elevated tank 21 is determined by observing the second transparent pipe 34；By above operation really
Protect in the middle of the running of first step, water supply tank 22 and elevated tank 21 are in the sufficient state of the water yield；
It is that second circulation pump 19 and first circulation pump 10 stop in running, when power failure phenomenon occur in first step
Only, second step is now carried out；
Second step is staff's observation thermometer 31, first pressure table 37 and second pressure table 38 after power failure；When
When thermometer 31 shows the temperature of water leg 24 higher than 75 degree, in water leg 24, existing part water is vaporized；Threeth is now opened
Valve 33, the water vapour in water leg 24 are passed through water supply tank 22 by the 6th pipeline 25, make between water supply tank 22 and water leg 24
It is in identical pressure；Staff by first pressure table 37 and second pressure table 38 confirm water supply tank 22 and water leg 24 it
Between open the second valve 28 after the identical pressure, the water in water supply tank 22 flows into water leg 24, and water in the water supply tank 22
In the presence of pressure, the heated water in water leg 24 flows to heat exchange box 3 by the first pipeline 6, finally flows into tank 2；
If first not opening the 3rd valve 33 and directly opening the second valve 28, the water in water leg 24 may be caused because of pressure
Power is raised（The water contacted with electric arc furnaces 1 can be vaporized because not flowing, and cause pressure rise）And flow backwards to water supply tank 22, so
The water in water supply tank 22 will be caused to flow downwardly into water leg 24, the water in water leg 24 dryouies, steam pressure is low
In the hydraulic pressure of water supply tank 22, so as to cause safety problem and steam contamination problem in the process.
In the middle of the carrying out of second step, staff persistently carries out following two operations：
1. thermometer 31 is observed, after thermometer 31 shows the water temperature of water leg 24 less than 50 degree, the second valve 28 is closed；
Water temperature in water leg 24 is gone up to after more than 75 degree, reopens the second valve 28；This operation is prevented from water supply tank 22
Interior water is too fast to flow into water leg 24, so that the heat energy not fully absorbed in electric arc furnaces 1 is just spilt out by the first pipeline 6.
The meaning of this operation makes full use of the ability that water in water supply tank 22 absorbs heat energy when being to have a power failure.
2. the liquid level that is observed in water supply tank 22 by the first transparent pipe 29, when in water supply tank 22, liquid level is high less than water supply tank 22
Degree 1/3 when, open the 3rd valve 33 and diffusion valve 30, make the water in elevated tank 21 inject water supply tank by the 8th pipeline 32
22, water supply tank 22 fills the water in 22 elevated tank 21 of water or water supply tank when using up, and closes the 3rd valve 33 and diffusion valve 30.
In first step, while second circulation pump 19 and first circulation pump 10 is started, start blower fan 18 so as to accelerating
The radiating of indirect cooling water.
During normal work（Do not have a power failure）, the carrying out practically situation of first step is：Start first circulation pump 10 and second to follow
Water in tank 2 is sent in the water leg 24 of electric arc furnaces 1, for cooling down electric arc furnaces 1 by ring pump 19, second circulation pump 19；From
The coolant-temperature gage flowed out in water leg 24 is higher, and such as directly discharge will produce substantial amounts of steam, pollutes working environment, makes plant area's wall
It is damaged because long-term moist.In the utility model, the water flowed out from water leg 24 sends into heat exchange box 3, by heat exchange box 3
During pipe 4, there is heat exchange with the cooling water outside pipe.The setting of heat exchange disc 5 can greatly improve heat exchange efficiency, and because change
The presence of hot hole 12 and not excessively affect cooling water flowing.After heat exchange, the temperature of the water flowed out from 1 water leg of electric arc furnaces 24
Degree is greatly reduced, finally by the bottom that the second pipeline 7 injects tank 2.If the second pipeline 7 is not passed through tank 2
Bottom, but opening is in 2 ullage of tank, then a small amount of steam still can be flowed out from the second pipeline 7, environment is caused few
Amount steam contamination；Second pipeline 7 is not passed through the bottom of tank 2, then steam can be avoided completely to permeate into showing in air
As.Second circulation pump 19 makes this part water circulate in 1 water leg 24 of electric arc furnaces, between heat exchange box 3 and tank 2, continues
Ground cooling electric arc furnaces 1.
First circulation pump 10 will cool down tower bottom water send into heat exchange box 3, this flow direction of part water in heat exchange box 3 with interior
In pipe 4, water flows to contrast, forms countercurrent flow, and the efficiency for cooling down water in inner tube 4 is higher.This part water is through the 3rd pipeline
88 flow out, and flow to the top of cooling tower, flow to ground floor seal cup 17 in the presence of hydraulic pressure, and step by step to underflow stream.Overflowing
During stream, blower fan 18 is dried, and accelerates the heat exchange of water and air.Behind 13 bottom of cooler bin of water overflow to cooling tower, quilt
First circulation pump 10 is extracted out again, carries out next round recuperated cycle.
Above example is only in order to illustrative and not limiting the technical solution of the utility model, although reference above-described embodiment pair
The utility model has been described in detail, it will be understood by those within the art that：Still the utility model can be entered
Row modification or equivalent, without deviating from any modification or partial replacement of spirit and scope of the present utility model, which all should
Cover in the middle of right of the present utility model.
