Abstract
The utility model provides a kind of roughing runner head water cooling mouth, including steel plate groove body, castable, water inlet pipe and outlet pipe；The spill groove body for the cavity type structure that the steel plate groove body is welded using steel plate, spill groove body steel plate surrounding welded seal, cavity inside is welded with baffle, it is welded with water inlet pipe and outlet pipe respectively in the upper end of spill groove body two sides, it is welded with anchor studs on cavity inner wall, has poured high temperature resistant castable in the inner surface of spill groove body.The utility model can guarantee cooling water circulating cooling, improve cooling effect, and the high temperature resistant castable above water cooling mouth using that can re-start casting after a certain period of time, to extend the service life of water cooling mouth.
Description
Technical field
The utility model belongs to roughing runner head water cooling mouth before ironmaking equipment field more particularly to a kind of State of Blast Furnace.
Background technique
The position of roughing runner head water cooling mouth receives tower contact position in roughing runner front end and flushing cinder before State of Blast Furnace, water cooling mouth
Front end be exactly flushing cinder receive tower, the main function of water cooling mouth be make high-temperature liquid state slag by water cooling mouth flow into receive tower and regardless of
Stream, another effect of water cooling mouth is that the reception tower Punched box below water cooling mouth is protected not to be damaged.U-typed is mainly used at present
Cast iron water-cooling mouth structure form.Cooling water pipe is inlayed inside cast iron water-cooling mouth, there is a water inlet and discharge outlet, when use in water cooling mouth
Water is pressed to carry out circulating cooling to extend the service life of water cooling mouth in portion.
Blast fumance is ever-changing, such as encounters tapping molten iron flow velocity fast, the splash of iron mouth, furnace temperature variation can all lead to slag iron point
Occur from bad situation, cause slag band iron and cause cast iron water-cooling sharp-tongued bad, allow during normal tapping slag band 1~
3% molten iron, and with the naked eye can't see when a small amount of molten iron of slag band during tapping.Cast iron type water cooling mouth is although interior
Portion's water flowing, but due to design, material, structure etc., cast iron type ditch head water cooling mouth has been unable to satisfy the daily life of large blast furnace
It produces and needs.On the other hand, cast iron type ditch head water cooling mouth can not be repaired once breakage occurs.Water cooling mouth occurs during tapping
It will lead to slag when damaged and " blow out " phenomenon, threat is all brought to stokehold post personnel and equipment, so ditch head water cooling mouth is damaged
When leading to slag tapping " blowing out ", stokehold must block up big gun in time and stop tapping, seriously affect the normal production of blast furnace.
Summary of the invention
The utility model is intended to provide a kind of easy to maintenance, low roughing runner head water cooling mouth of breakage rate.
The utility model takes following technical solution:
A kind of roughing runner head water cooling mouth, including steel plate groove body, castable, water inlet pipe and outlet pipe；The steel plate groove body is adopted
With the spill groove body for the cavity type structure that steel plate is welded, spill groove body steel plate surrounding welded seal, cavity inside is welded with gear
Plate is welded with water inlet pipe and outlet pipe in the upper end of spill groove body two sides respectively, anchor studs is welded on cavity inner wall, in spill groove body
Inner surface poured high temperature resistant castable
The high temperature resistant castable pours with a thickness of 90~120mm.
The upper surface of the steel plate groove body is welded with hanging ring.
The utility model has the following beneficial effects:
The utility model water cooling mouth uses cavity type structure, and inside is welded with baffle, it is ensured that cooling water circulating cooling mentions
High cooling effect.The inner surface of spill groove body pours high temperature resistant castable, and effective protection water cooling mouth is not burnt out by slag iron, improves water
Cold mouth service life；Castable above water cooling mouth uses can be poured again after a certain period of time, and spill groove body is once damaged,
Also it may be repaired, reduce waste of material.
Detailed description of the invention
Fig. 1 is roughing runner head water cooling mouth main view；
Fig. 2 is roughing runner head water cooling mouth side view.
In figure: steel plate groove body 1, high temperature resistant castable 2, water inlet pipe 3, outlet pipe 4, anchor studs 5, baffle 6, hanging ring 7.
Specific embodiment
By attached drawing as it can be seen that the utility model roughing runner head water cooling mouth, including steel plate groove body 1, high temperature resistant castable 2, water inlet
Pipe 3 and outlet pipe 4.Steel plate groove body 1 is the spill groove body of cavity type structure, is to be welded using 15mm thick steel plate, baltimore groove
The equal welded seal of steel plate surrounding of body, cavity inside are welded with baffle 6, are welded with water inlet pipe 3 respectively in the upper end of spill groove body two sides
With outlet pipe 4, anchor studs 5 are welded on cavity inner wall, have poured high temperature resistant castable 2, high temperature resistant in the inner surface of spill groove body
Castable 2 pours with a thickness of 100mm.To be also welded with hanging ring 7 in the upper surface of steel plate groove body 1 convenient for handling.Water cooling mouth uses
High temperature resistant castable 2 can be poured again after a period of time, to extend the service life of water cooling mouth.
