Description
Technical field
It the utility model is related to continuous casting field, and in particular to a kind of submersed nozzle roasting for the cast of vanadium ferrotianium
Device.
Background technology
When pouring into a mould molten steel, in order to improve efficiency, often by the way of conticaster cast, so can continuously pour
Note multiple steel billets.During continuous cast, in order to avoid air and steel contacts, prevent molten steel from producing secondary oxidation in cast, need
Submersed nozzle to be used as sprue gate, so before pour steel, it is necessary to baking preheating is carried out to submersed nozzle, with
Submersed nozzle is prevented because preheating bad or long-time low-temperature prewarming, and causes intensity decreases, or serious oxidation occurs
Phenomenon, or even submersed nozzle is burst in use.
Most of steel mill's protective casting submersed nozzles use resistance wire using point baking box mode, electric oven at present, electricity
Resistive heating power is standby to 800 DEG C or so by submersed nozzle roasting, and existing baking preheating is unreasonable there is being heated,
Toast the problems such as uneven, and submersed nozzle is frequently removed and placed into baking, be easily destroyed the mouth of a river, meanwhile, drying
During roasting, because resistance wire is for a long time using that can blow, submersed nozzle is caused to toast, and resistance wire blows rear baking box
Interior temperature is higher, it is impossible to changes resistance wire in time, could be repaired after the temperature inside the box is cooled to room temperature, allows and toast immersion water
Mouth delay, not only influences production efficiency, potential safety hazard also be present.
Utility model content
In view of this, the application provides a kind of immersed nozzle heating device for the cast of vanadium ferrotianium, and the device uses
Coal gas of converter burning is used as thermal source, and without increasing other energy mediums, and submersed nozzle is heated evenly, and is more cleaned resistance to
With, it is safe and practical, improve production efficiency.
To solve above technical problem, technical scheme provided by the utility model is a kind of immersion for the cast of vanadium ferrotianium
Formula mouth of a river apparatus for baking, including upper cover body and baking box, it is characterised in that the upper cover body is provided with jack, the baking
Roasting bottom half is provided with jack, and roasting nozzle is provided with the jack of the baking box bottom.
Preferably, the roasting nozzle bottom is provided with air blower.
Preferably, it is provided with igniter on the roasting nozzle.
Preferably, the upper cover body and the baking box inwall are provided with high-temperaure coating.
Preferably, it is iron sheet layer outside the upper cover body and the baking box.
Preferably, the upper cover body is provided with one or more jacks.
It is preferred that volume, the submersed nozzle is arranged on the socket of the upper cover body, is immersed in the baking box.
Compared with prior art, its detailed description is as follows by the application：It is used for what vanadium ferrotianium was poured into a mould this application provides a kind of
Immersed nozzle heating device, the device mainly include upper cover body and baking box, and upper cover body and baking box are set respectively
There is jack, the wherein jack of upper cover body can be one or more, and submersed nozzle is arranged in the jack of upper cover body, leaching
Enter into baking box, roasting nozzle is installed on the jack of baking box bottom, igniter is provided with roasting nozzle, from baking
Coal gas of converter is passed through in grilling mouth, then coal gas of converter is lighted with igniter and the mouth of a river in baking box can be dried
Roasting, roasting nozzle bottom is additionally provided with air blower, air blower air is blown into roasting nozzle carry out it is combustion-supporting.Upper cover body and baking
The inwall of casing is provided with high-temperaure coating, and because the mouth of a river requires heat to 800 DEG C, high-temperaure coating can be to upper cover body and baking
Baking box body plays a protective role, and increases the service life of apparatus for baking, and the outside of upper cover body and baking box is iron sheet layer.
What immersed nozzle heating device provided by the utility model utilized is the self-produced coal gas of converter of steel plant, it is not necessary to
Increase other energy mediums, the energy is effectively utilized, economized on resources, submersed nozzle is inserted into the socket of upper cover body
In, in roasting nozzle point coal gas, and air is passed through by air blower and carries out combustion-supporting, the coal gas of converter of burning is carried out to the mouth of a river
Heating, device cleaning is durable, safe to use, and can continuously toast, and improves such as production efficiency, has saved and be produced into
This.
Brief description of the drawings
Fig. 1 is the schematic diagram of immersed nozzle heating device of the present utility model
