Description
Technical field
The utility model belongs to the improvement of Blast Furnace Bottom cooling device structure, particularly a kind of to subside in Blast Furnace Bottom corrosion
Forced air cooled tube interplantation bar device.
Background technology
The purpose of Blast Furnace Bottom cooling, in the distribution of cupola well furnace bottom, makes brick fuel try one's best i.e. by 1150 DEG C of thermoisopleths of control
Avoid 800～1100 DEG C of embrittlement point intervals.Its principle is, using the excellent carbon brick of high heat conduction, iron-resistant water permeation performance, to pass through
Rational cooling, enables the hot face of brick fuel to form protective slag crust or iron-clad, and 1150 DEG C of thermoisopleths are arrested in into it
In, make brick fuel be effectively protected, the destruction such as permeate, wash away from molten iron.
Blast Furnace Bottom adopts air-cooled technology, and the intensity of cooling of this kind of cooling technology is relatively low.If furnace bottom carbon brick quality is present asking
Topic, using to the blast furnace middle and later periods, forced air cooled tube subsides can cause furnace bottom forced air cooled tube cooling capacity to decline, and such as monitor not in place, can enter
One step deteriorates, and causes air-cooled blockage, cracking, may finally cause sudden burn-through of furnace hearth accident.
Utility model content
The purpose of this utility model is to provide a kind of forced air cooled tube interplantation bar device subsided in Blast Furnace Bottom corrosion, its knot
Structure rationally, using original serious forced air cooled tube that subsides, by air-cooled water-cooled is changed, and intensity of cooling is big, can reduce Bottom Temperature,
Improve blast furnace service life.
What the purpose of this utility model was realized in：A kind of planting-peg dress in the forced air cooled tube that Blast Furnace Bottom corrosion is subsided
Put, the cooling tube of closed at both ends is eccentrically mounted in forced air cooled tube, and the inner end of cooling tube is located at the place that subsides of forced air cooled tube, cooling
The axle center of pipe is located at the lower section in forced air cooled tube axle center, is supported by locating piece in cooling tube and is installed with water cooling tube, the pipe of water cooling tube
Mouth leaves gap away from cooling tube inner end sealing end, and the conduit by arranging in the forced air cooled tube on water cooling tube top is installed with thermoelectricity
It is even, the valvular inlet tube of dressing is set on forced air cooled tube is lengthened, the valvular outlet of dressing is set on conduit, by entering
Mouth pipe arranges aluminium silicon carbide carbon material into forced air cooled tube, and on the shrouding of cooling tube outer end outlet pipe is arranged.
Principle of the present utility model is that water cooling tube is inserted in forced air cooled tube middle part, and cooling water is entered by forced air cooled tube, at the end of forced air cooled tube
End enters water cooling tube. and size is custom according to actual conditions and cooling water flow.Locating piece holder device, the effect of keeper,
Water cooling tube horizontal centre is installed.Thermocouple, its its front end is inserted in center.
Conduit plays a part of to record aluminium silicon carbide carbon material final vacuum and fixed thermocouple.Aluminium silicon carbide carbon material,
Thermal conductivity factor is sought more than 2.5.Inlet tube is the inlet device for recording aluminium silicon carbide carbon material.Outlet is to record aluminium silicon carbide
The outlet device of carbon material, plays a part of exhaust.Outlet pipe is the effect that cooling water is discharged.
Main contents
1st, the size of L, determining member forced air cooled tube, the length of water cooling tube are measured.Make outside stove.Positioning is welded on water cooling tube
Block, the forced air cooled tube of water cooling tube insertion afterwards, in the top perforate of water cooling tube, insertion conduit connects slit after in place in tapping full weld.
Catheter proximal end is allowed some leeway, nock peace outlet, and front end is welded the pipe screw thread for installing thermocouple.Complete the making of planting-peg.
2nd, inlet tube is welded.
3rd, planting-peg part is inserted inside forced air cooled tube.In place rear enclosed is fixed, firm welding.Thermocouple is inserted so as to most
Front end subsides with forced air cooled tube and locates to contact.
4th, from inlet tube as entrance, outlet records aluminium silicon carbide carbon material as outlet, it is desirable to record full, outlet
Stop after pipe pulp, closure member inlet tube, outlet.
5th, the upper front end in forced air cooled tube welds outlet pipe.Cooling water is entered by the front end stream of water cooling tube.Through its end stream
Enter forced air cooled tube, flow out through outlet pipe from the front end of forced air cooled tube.
The utility model is rational in infrastructure, using original serious forced air cooled tube that subsides, by air-cooled water-cooled is changed, and intensity of cooling is big,
Bottom Temperature is reduced, blast furnace service life is improve.
