Description
Technical field
This utility model is related to steel casting protection device field, specifically refers to one kind and produces special steel using the method that is molded into
Steel ingot steel pouring process reduces the argon protective device of secondary oxidation of steel.
Background technology
It is necessary to cast the ingot of definite shape or base just can be processed after the completion of molten steel is smelted in converter.Use mold
The technical process casting steel ingot is referred to as ingot casting.Steel ingot casting divides downhill casting and two kinds of bottom casting.
, in mould casting process, the space at cup and mouth of a river interval will be completely sudden and violent for molten steel taking bottom casting as a example
It is exposed in the air, greatly increases the secondary oxidation to molten steel for the air, in the steel ingot making gained, produce a large amount of field trashes.In order to overcome
The problems referred to above, argon protective device occurs at present.But existing argon protective device is usually the annular of surface perforate
Airway.By perforate jet on annular airway, reduce the air content of cup and mouth of a river clearance space, thus reducing folder
The content of debris.
Existing argon protective device using effect is poor, still can produce more field trash, the matter of impact gained steel ingot
Amount.Research and analyse discovery through applicant it is believed that main reason is that, existing argon protective device is single respectively by multiple perforates
Solely supplement argon it is impossible to form the argon space of closing, outside air can constantly enter in cup and mouth of a river clearance space, no
Method forms a hardly aeriferous straight argon headroom.
Utility model content
The purpose of this utility model is：Overcome prior art drawbacks described above, provide one kind can reduce steel pouring process molten steel
The argon protective device of secondary oxidation.This utility model, when using, can form one in the clearance space at cup and the mouth of a river
Individual hardly aeriferous straight argon headroom, effectively completely cuts off outside air, significantly reduces molten steel and produced by outside air secondary oxidation
Raw field trash, improves the quality of gained steel ingot.
This utility model is achieved through the following technical solutions：
A kind of argon protective device that can reduce steel pouring process secondary oxidation of steel, including argon ring and aeroscopic plate, described
Argon ring includes cannelure, is placed with the first airway in described cannelure, and described first airway is connected with the first air inlet pipe,
