Abstract
The utility model discloses a kind of blast furnace iron storage type trough tap drain structure, including tap drain ontology, the liquid feeding end of tap drain ontology is mutually connected with molten iron outlet, and outlet end is connected with trough；It is connected to the trough of oriented ditch body side extension close to tap drain ontology outlet end, is provided with skimming tool on the tap drain ontology between trough and the trough；Tap drain ontology is in bell-mouth structure of air from middle part to liquid feeding end tapering width.The utility model can effectively avoid the molten iron sprayed from falling formation whirlpool at iron spot in tap drain, facilitate the separation of molten iron and molten iron slag, improve the service life of tap drain；The entire length for effectively shortening tap drain not only saves refractory material, but also reduces the temperature reduction of molten iron；The thickness for increasing front half section two sidewalls, can resist high temperature liquid iron and slag washing away and corroding to main hook；The smooth avoidable molten iron slag surface lumps of molten iron flow, facilitate the separation of molten iron Yu molten iron slag, reduce the labor intensity of worker.
Description
Technical field
The utility model relates to blast furnace ironmaking fields, and the blast furnace of service life can be increased substantially more particularly, to one kind
Iron storage type trough structure.
Background technique
When blast furnace casting, molten iron first has to enter back into trough by one section of wider tap drain after tapping hole outflow；It is main
Ditch is the critical facility before State of Blast Furnace, and function is to realize efficiently separating for liquid slag and iron.Tap drain is due to blast furnace iron to be born
Water and high-temperature slag are washed away, corrode and are permeated, therefore service life is lower；Traditional tap drain front and rear width is consistent, be compared with
Wide channel, it is blast-melted to be sprayed from tapping hole, falling at iron spot position for tap drain front end is fallen in, due to falling tap drain width at iron spot
It is wider, cause falling formation whirlpool at iron spot, can not flow to the back-end in time, increase molten iron and molten iron slag falls iron spot to tap drain
Locate refractory material erosion and wash away, therefore tap drain fall iron spot position wash away and corrode it is the most serious；Existing many Nai Cai factories
Family is the class by improving refractory material, and the service life of tap drain is improved using modes such as various micro mists, import additives,
The construction cost for considerably increasing tap drain so is not greatly improved the service life of such tap drain.
Summary of the invention
The utility model aim is to provide a kind of blast furnace iron storage type trough knot that can increase substantially service life
Structure.
To achieve the above object, the utility model can take following technical proposals：
Blast furnace iron storage type trough tap drain structure described in the utility model, including tap drain ontology, the tap drain ontology
Liquid feeding end is mutually connected with molten iron outlet, and outlet end is connected with trough；It is connected to close to the tap drain ontology outlet end oriented
The trough that ditch body side extends is provided with skimming tool on the tap drain ontology between the trough and the trough；Institute
Tap drain ontology is stated from middle part to liquid feeding end tapering width, is in bell-mouth structure of air.
The liquid feeding end of the tap drain ontology and the width ratio in the middle part of tap drain ontology are 2:3.
The utility model advantage is that structure is simple, easy construction.Tap drain ontology gradually contracts from middle part to liquid feeding end width
It is small, it is in bell-mouth structure of air, can effectively avoids the molten iron for exporting ejection from molten iron from falling formation whirlpool at iron spot in tap drain ontology, make
Molten iron flow it is more smooth, reduce high temperature liquid iron and slag washing away and corroding to tap drain ontology, improve the use of tap drain
Service life；Leading portion easily facilitates the separation of molten iron and molten iron slag in the tap drain ontology of bell-mouth structure of air simultaneously, can effectively shorten tap drain
Entire length, refractory material can either be saved, but reduce molten iron temperature reduce；Third, leading portion is in bell-mouth structure of air
Tap drain ontology also effectively increases the thickness of front half section two sidewalls, can resist high temperature liquid iron and slag washing away and invade to main hook
Erosion；4th, leading portion can accelerate molten iron and molten iron slag to flow to posterior segment in the tap drain ontology of bell-mouth structure of air, avoid molten iron slag
Surface lumps facilitate the separation of molten iron Yu molten iron slag, reduce the labor intensity of worker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model（It overlooks）.
Fig. 2 is the sectional view of tap drain ontology in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, blast furnace iron storage type trough tap drain structure described in the utility model, including tap drain ontology 1, it is main
The liquid feeding end of ditch ontology 1 exports 2 phases with molten iron and is connected, and outlet end is connected with trough 3；Close to 1 outlet end of tap drain ontology
It is connected to the trough 4 of oriented ditch body side extension, the molten iron slag for being discharged in molten iron, between trough 4 and trough 3
Skimming tool 5 is provided on tap drain ontology 1；For the service life for improving tap drain ontology 1, the molten iron for exporting ejection from molten iron is avoided to exist
Tap drain ontology falls formation whirlpool, tapering width of the tap drain ontology 1 from middle part to liquid feeding end at iron spot, makes it in horn mouth knot
Structure.Under normal circumstances, the width ratio at 1 middle part of the liquid feeding end of tap drain ontology 1 and tap drain ontology is 2:3 are advisable, when Specific construction,
Its width ratio can be adjusted according to the actual situation.
The front half section of tap drain ontology 1 is designed to bell-mouth structure of air, can effectively avoid and exist from the molten iron that molten iron outlet 2 sprays
Tap drain ontology 1 falls formation whirlpool at iron spot, so that molten iron is quickly trickled to the posterior segment of tap drain ontology 1, reduces to tap drain ontology 1
Wash away and corrode, substantially increase the service life of tap drain ontology 1.
Be 18200mm with existing length, width for 700mm 1080m3For blast furnace iron outlet groove, when tap drain ontology 1
Liquid feeding end width is changed to 500mm, and middle part width is changed to 750mm（That is the width at 1 middle part of the liquid feeding end of tap drain ontology 1 and tap drain ontology
Degree is than being 2:3）, when length is kept to 17008mm, goes out iron by intrinsic 130,000 tons and rise to 14.6 ten thousand tons（Iron increases out
Add 1.6 ten thousand tons）, service life extended to 90 days by 80 days（Service life increases by 10 days）；Resistance to material dosage is also ad save simultaneously,
Without using more high-grade refractory material, construction cost is reduced.
