Description
Technical field
A kind of converter oxygen gun cooling device is the utility model is related to, particularly relates to a kind of converter oxygen gun cooling water
Water saving fixtures.
Background technology
Pneumatic steelmaking is to be blown by oxygen rifle to raw materials such as the molten iron in stove, steel scrap, ferroalloys, to obtain molten steel
Method for making steel.At present, two oxygen rifles are provided with pneumatic steelmaking equipment, and configure the cooling that cooling water system is used for oxygen rifle.
Oxygen rifle meeting dry slag during bessemerizing, therefore, general to be blown using an oxygen rifle, another oxygen rifle splashes the operating method of slag.
The oxygen rifle of finishing blowing is displaced to maintenance position from blowing, meanwhile, another oxygen rifle is displaced to working position from the maintenance of another side and blows
Nitrogen slag splashing.Gradually cooling voluntarily comes off the slag that such operating method can make to glue in blowing oxygen rifle.
In convertor steelmaking process, if the oxygen rifle for moving on to maintenance position directly closes cooling water, it is waited to move on to blowing position again
When opening cooling water, serious water hammer can be produced, so as to cause oxygen rifle cooling tube to burst, very big shadow is caused to production
Ring.Therefore, the cooling water of two oxygen rifles needs always on.It will necessarily be caused however, the cooling water of two oxygen rifles is always on
The waste of the energy.
Utility model content
Purpose of utility model：The utility model provides a kind of converter oxygen gun cooling water saving device, which can reduce
The cooling water flow of position oxygen rifle is repaired, so as to fulfill the purpose of cooling water is saved.
Technical solution：A kind of converter oxygen gun cooling water saving device, including two oxygen rifles and connect respectively with two oxygen rifles
The two water inlet supervisors connect, two water inlet supervisors are equipped with supervisor's remote control stop valve, are also associated with water inlet supervisor
Water inlet pipe, the both ends of the water inlet pipe are connected to the inlet side and outlet side of supervisor's remote control stop valve, water inlet
One or more branch pipe stop valves are provided with branch pipe.
Wherein, the converter oxygen gun cooling water saving device is additionally provided with PLC control devices, and supervisor's remote control is cut
Disconnected valve is electrically connected with the PLC control devices.So as to fulfill the remote auto control to being responsible for remote control stop valve.
The branch pipe stop valve is branch pipe remote control stop valve or branch pipe hand off valve.Come into operation debugging when, pass through
Branch pipe cut-out valve opening is adjusted, reduces the oxygen gun cooling water flow of maintenance position.
Beneficial effect：A kind of converter oxygen gun cooling water saving device described in the utility model, by water inlet supervisor
Supervisor's remote control stop valve and water inlet pipe are set, and branch pipe stop valve is set on water inlet pipe, so as to fulfill oxygen is worked as
When rifle is in different station, the opening and closing of supervisor's remote control stop valve of the water inlet supervisor of remote control oxygen rifle；Meanwhile oxygen rifle
Cooling water can remain unlatching, by controlling the aperture of branch pipe stop valve or reducing the caliber of water inlet pipe, realize
Water-saving purpose；Water inlet supervisor's remote control stop valve is opened when oxygen rifle moves on to blowing position, water hammer will not be produced, both protected
The safety of equipment has been demonstrate,proved, and has had significant water-saving result, has reduced energy waste.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of converter oxygen gun cooling water saving device, the dioxygen rifle 1 which is suitable for converter current steel-making is grasped
Make mode, which includes two oxygen rifles 1 and the water inlet supervisor 2 of cooling water is provided to two oxygen rifles 1, on water inlet supervisor 2
Flowmeter 7, supervisor's hand off valve 8 and supervisor's remote control stop valve 3 have been set gradually along cooling water circulating direction.At the same time
Water inlet pipe 4 all the way are also set up on water inlet supervisor 2, the water inlet end of water inlet pipe 4 is connected to supervisor's hand off valve 8 and supervisor is remote
It is outlet side and the long-range control of supervisor for being connected to supervisor's hand off valve 8 on water inlet supervisor 2 between process control stop valve 3
On water inlet supervisor 2 between 3 inlet side of stop valve processed；The water outlet of water inlet pipe 4 is connected to supervisor's remote control stop valve 3 and goes out
On the water inlet supervisor 2 of mouth side.Branch pipe remote control stop valve 5 and branch pipe hand off valve 6 are provided with water inlet pipe 4.
Wherein, it is electronic stop valve or pneumatic cut-out to be responsible for remote control stop valve 3 and branch pipe remote control stop valve 5
Valve.Meanwhile to realize the remote auto control of supervisor's remote control stop valve 3 and branch pipe remote control stop valve 5, in converter master
Control room is additionally provided with PLC control devices, which is existing converter control device, such as：Siemens S7-300, sieve
Ke Weier ControlLogix series etc..Remote control stop valve 3 and branch pipe remote control stop valve 5 are responsible for by circuit with turning
The control terminal of the PLC control devices of stove is connected.
Before this converter oxygen gun cooling water saving device comes into operation, first it is debugged, by adjusting branch pipe hand off valve 6
Aperture, by when only water inlet pipe 4 is opened water flow adjust to water inlet supervisor 2 and water inlet pipe 4 open when water flow
1/4, then fix the aperture of branch pipe hand off valve 6.When the converter oxygen gun cooling water saving device works, blowing is in
The supervisor's remote control stop valve 3 and branch pipe remote control stop valve 5 of the oxygen rifle 1 of position are in an open state, and are in maintenance position
Oxygen rifle 1 then close supervisor's remote control stop valve 3, branch pipe remote control stop valve 5 stays open, and at this time, oxygen rifle 1 can be water-saving
3/4, convert to two then water-saving 3/8.Open supervisor's remote control stop valve 3 again when the oxygen rifle 1 for repairing position moves on to blowing position,
Water hammer would not be produced, not only ensure that the safety of equipment, but also has significant water-saving result.
In addition to the embodiments described above, the cold of water inlet pipe 4 can also be flowed through to control by reducing the caliber of water inlet pipe 4
