Description
Technical field
The present invention relates to electric furnace arrangement for producing steel technical field, more particularly to a kind of electric furnace arrangement for producing steel wall lance.
Background technology
Oxygen rifle, is one of major process unit in oxygen converter steelmaking, and its performance characteristic directly influences metallurgical effect
And duration of blast, so as to have influence on the quality of steel and yield.Oxygen rifle is by high pressure, high purity degree oxygen or nitrogen with hypersonic velocity
It is blown into converter above metal bath, and carries water under high pressure cooling protection system.Oxygen needed for converter smelting or nitrogen pass through oxygen
Gas is supplied, and quantity delivered is controlled to be accurate, therefore the gas flow of accurate measurement oxygen rifle is crucial, and converter oxygen gun gas flow is mainly
By installing what pressure gauge was realized on oxygen or nitrogen storage tank escape pipe, but this set can not realize on-line correction and inspection
Survey, can only be corrected under line, influence converter and normally produce, at present it has been proposed that a kind of scheme, its structure generally in oxygen rifle
External mechanical pressure sensors, using this pressure sensor on-line checking and correction converter oxygen gun gas flow, but in reality
Found in the application of border, due to bearing 2500 DEG C of high temperature at oxygen rifle place, the operating temperature requirements of mechanical pressure sensors exist
Less than 100 DEG C, therefore can not normal work.
The content of the invention
The present invention it is above-mentioned in order to overcome the shortcomings of, there is provided a kind of electric furnace arrangement for producing steel wall lance, including from front to back according to
Middle pipe and outer tube are arranged with outside shower nozzle, inner tube and the tail pipe of secondary connection, inner tube and shower nozzle, inner tube, the tube and the outer tube are arranged concentrically,
It is respectively equipped with the first water inlet pipe and the second water inlet pipe in middle pipe and outer tube, inner tube is provided with breather pipe, and the is arranged with outside breather pipe
One cooling tube and the second cooling tube, the first cooling tube connect with middle pipe, and the second cooling tube connects with outer tube, pass through the first water inlet pipe
Cooling water is injected into middle pipe and outer tube with the second water inlet pipe, cooling water also cools while cooling to inner tube to breather pipe,
Gas pressure sensor is provided with breather pipe.
Preferably, the breather pipe is made up of high temperature resistant mica.
Preferably, the gas pressure sensor, which is connected through a screw thread, is fixed in breather pipe.
Preferably, first water inlet pipe and the second water inlet pipe are welded to connect with middle pipe and outer tube respectively.
Preferably, the gas pressure sensor is wireless gas pressure sensor.
The beneficial effects of the invention are as follows：The present invention is simple in construction, reasonable in design, utilizes the cooling water to cool to oxygen rifle inner tube
System, while cool to breather pipe mounted on the inner tube, ensure the gas pressure sensor operating temperature of installation in breather pipe
Requiring in operating temperature range, making gas pressure sensor can be with gas pressure in accurate measurement oxygen rifle, and oxygen is calculated with this
Gas flow in rifle, to reach the purpose of accurate control gas delivery volume.
