Description
Technical field
The present invention relates to EAF smelting stove technical field of auxiliary equipment, particularly relate to a kind of EAF smelting furnace bottom electronic flat
Car and means of defence thereof.
Background technology
At present, in most domestic steel-casting foundry EAF smelting process, in order to reach dephosphorization effect, there is stream slag in the heat of oxidation
Operation.For ensureing to smelt benefit, the general EAF blow-on frequency is high, and high-temperature steel slag accumulates over a long period, and needs rationally to process.It is usually taken
Way be EAF furnace bottom install an electric flat carriage, electric flat carriage is placed above a slag pan, need flow slag time by stream slag
Mouthful by high-temperature steel slag stream on furnace bottom slag pan.After slag pan fills with, electric flat carriage is outputed, and is reapposed over electronic flat after slag pan overturning
Che Shang, opens into furnace bottom standby.
The slag temperature flowed out from EAF stove, at 850～950 DEG C, uses above-mentioned Slagoff method, because EAF stove has with slag pan
Difference in height, during deslagging, high-temperature steel slag easily spills and falls on electric flat carriage；Or because producing continuously, slag pan is
Full and not free overturning, EAF stove continues stream slag, causes high-temperature steel slag to flow out slag pan and is layered on electric flat carriage.Electric flat carriage
Agent structure is made up of exotic material, and heat-resisting ability is strong, but stands slag impact for a long time and the most easily cause surface damage, enters
And jeopardize internal core structure.The more important thing is and be provided with motor bottom furnace bottom electric flat carriage, heat-resisting ability is poor, spill or
The high-temperature steel slag flowed out toasts motor for a long time, easily causes motor to damage, causes plant downtime.
Additionally, after spilling or spill into the high-temperature steel slag cooling on electric flat carriage, it usually needs 2～3 people utilize 2～3 little
Shi Jinhang clears up.In scale removal process, flatcar cannot use, and takies the resource such as overhead traveling crane, fork truck, and impact produces.
Summary of the invention
In view of this, it is necessary to a kind of simple in construction, the EAF smelting furnace bottom electric flat carriage of saving manpower are provided.
There is a need to provide the means of defence of a kind of EAF smelting furnace bottom electric flat carriage.
A kind of EAF smelts and uses furnace bottom electric flat carriage, including protection slag bucket, slag pan, electric flat carriage base plate, road wheel, described
Slag pan is arranged on protection slag bucket, and protection slag bucket is arranged on electric flat carriage base plate, and the lower end of electric flat carriage base plate arranges walking
Wheel, has spacing between outer wall and the inwall of protection slag bucket of slag pan；Arrange on protection slag bucket and hang handle, so that the boom hoisting in the external world
Protection slag bucket is sling.
Preferably, described protection slag bucket includes the slag bucket base plate of rectangle, four blocks of slag bucket side plates, and slag bucket base plate is arranged on electronic
On flatcar base plate and can separate with electric flat carriage base plate, four that are welded on slag bucket base plate that four blocks of slag bucket side plates are corresponding respectively
Bian Shang, so that the casing that protection slag bucket forms an open upper end, lower end seals, the upper end of side plate is provided with flanging.
Preferably, the sidewall of protection slag bucket arranges six and hangs handle, wherein, a sidewall of protection slag bucket arranges three
Hang and three hang in the same horizontal line, the sidewall of this protection slag bucket just to sidewall on be arranged in correspondence with three and hang handle.
Preferably, hang for umbrella described in, in order to extraneous boom hoisting is sling protection slag bucket.
The means of defence of a kind of EAF smelting furnace bottom electric flat carriage, comprises the following steps:
Furnace bottom electric flat carriage is outputed furnace bottom to slag pan handling station, the protection slag bucket mouth handling upward made is placed on electricity
Dynamic flatcar base plate central authorities, then the handling upward of slag pan mouth is placed on the centre of slag bucket base plate, by EAF smelting furnace bottom electric flat carriage
Open into Sheng slag station, stand-by；
EAF starts to smelt, and fusing later stage and the heat of oxidation start to flow slag, to high-temperature steel slag watering cooling during stream slag, treats slag
After high-temperature steel slag stream in dish is full, stops stream slag, and sprinkle water to slag pan, make high-temperature steel slag cool down rapidly；The most alternately to anti-
Protect slag bucket watering, it is to avoid high-temperature steel slag burns protection slag bucket；
After in slag pan, high-temperature steel slag is kermesinus, EAF smelting furnace bottom electric flat carriage is outputed to Rigger from containing slag station
Position, slag bucket is placed on EAF smelting furnace bottom electric flat carriage motionless, and slag pan is hung out to slag field by extraneous boom hoisting, and to
Slag field overturning high-temperature steel slag, then hangs the centre position being back to slag bucket base plate by slag pan, by EAF smelting with furnace bottom electric flat carriage from
Slag pan handling station drives into containing slag station, stand-by.
Beneficial effect: above-mentioned EAF smelting furnace bottom electric flat carriage and means of defence thereof compared with prior art, spill or overflow
The stream slag gone out will fall in protection slag bucket, thus avoid overheated stream slag to make the motor of electric flat carriage base plate and electric flat carriage
Become damage.Protection slag bucket can separate with electric flat carriage base plate simultaneously, and therefore the slag in protection slag bucket can be by the external world
Boom hoisting is transported to slag field topples over, and effectively reduces personnel's working time in the presence of a harsh environment, reduces and provides fork truck
Taking of source, improves person works's efficiency.
