Description
Technical field
The utility model is related to a kind of protection device, more particularly to a kind of argon protective device of ingot steel casting.
Background technology
Steel is significant to national development and people's lives, and steel and iron industry occupies critical role in national economy,
Indicate the degree of an industrialization of the country development.This patent is used for the production process of steel products wherein ingot casting, it is therefore an objective to carry
The internal soundness of high steel ingot.
Ingot casting is after the completion of molten steel is smelted in converter, it is necessary to which casting the ingot or base of definite shape can just be processed.
The technical process referred to as ingot casting of steel ingot is cast with mold.
As industrial products are upgraded, the rolling shapes for different requirements are more and more, require also more next to steel ingot therewith
It is stricter, and control the guarantor that the most important production link of ingot quality is exactly molten steel among the process of cast steel ingot to molten steel
Shield.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of argon protective device of ingot steel casting, rotating mechanism with
Collector nozzle of ladle is fixedly connected, and by controlling the gap between ladle elevating control protection board and gas shield set, uses inertia
Gas, prevents extraneous air from entering in molten steel, causes secondary oxidation to molten steel, protected in casting process.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of argon gas protection dress of ingot steel casting
Put, protection board upper surface is connected with inside argon envelope Quick Connect Kit, argon envelope Quick Connect Kit and is provided with distributing ring, and argon envelope is quick
Attachment means lower surface, which is fixedly connected with below protection board, protection board, is provided with feed trumpet, and gas is provided between protection board and feed trumpet
Funnel brick is provided with body protective case, feed trumpet cavity.
Described argon envelope Quick Connect Kit is made up of rotating mechanism and cavity structure, and rotating mechanism and cavity structure are fixed
Distributing ring is provided with connection, cavity structure cavity.
A described funnel brick part is located at feed trumpet inside cavity, and a part is located at gas shield and covers internal.
Described argon envelope Quick Connect Kit, gas shield set, funnel brick and feed trumpet is symmetrical structure, and axial line is equal
Overlapped with the axial line of collector nozzle of ladle.
What the utility model was brought has the beneficial effect that：Argon envelope Quick Connect Kit is connected to collector nozzle of ladle excircle,
Realize the reliable cut-off of air between device and ladle.
Steel stream naked section is presented malleation atmosphere, realizes that air curtain effectively protects molten steel under ar gas acting.
Brief description of the drawings

Axial line of the line with collector nozzle of ladle 1 is overlapped.
Rotating mechanism 8 is fixedly connected with the excircle of collector nozzle of ladle 1, the inside of gas shield set 4 is full of argon gas, argon gas
Malleation atmosphere is presented in gas shield set 4, realizes that annular air curtain is protected to molten steel, by controlling steel ladle lifting mechanism to adjust
The size of gas overflowing mouthfuls 10 between whole protection board 6 and gas shield set 4, if so that control gas overflowing number partially
Greatly, gas can be entered in molten steel, bad to steel ingot internal soundness, less than normal not have protective effect, also to poor quality.
Above-described is only preferred embodiment of the present utility model.It should be pointed out that for the ordinary skill people of this area
For member, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, also should be regarded as belonging to this
The protection domain of utility model.
