The developing direction of art.With regard to current production specifications, the control of impurity content has reached higher level (in steel in steel
Total impurities:S+P+N+H+T O≤100 × 10-6), and with the further reduction of impurity content in molten steel, pressed from both sides in steel
The harmful effect effect that debris are produced to steel products is just more obvious, therefore, the different quality according to product requires to control
Just it is particularly important with the proterties for improving steel inclusion.
The most typical, inclusions class technology that is being most widely used is the Calcium treatment of Al deoxidization steel.Calcium treatment can
It is transformed into the composite oxides of low melting point so that Al2O3 in steel to be mingled with, is conducive to its polymerization to grow up from molten steel and excludes, not only
Can anti-waterstop port freeze, and the quantity that oxide in steel is mingled with can be reduced；Meanwhile, it is trapped in field trash its shape in steel
Shape is almost circular and is irregularly distributed in steel, can mitigate the harm to Steel Properties.But the problem that Calcium treatment is present
It is：Although the quantity that oxide is mingled with steel can be greatly reduced, the field trash that left behind often size than larger, by
It is unlikely to deform in CaO Al2O3 field trashes, micro-crack, cavity can be formed along deformation direction around field trash in the operation of rolling,
Cause a series of deterioration of performances of steel.Particularly those have the steel grade of rigors for fatigue behaviour, aborning then not
Allow to use Calcium treatment.For the pure product made from steel of higher quality requirement, new inclusion modification means are found, to mitigate and disappear
Except the harm caused by aluminium deoxidation steel inclusion, a problem in the urgent need to address in steel products production is had become.
Magnesium not only has fabulous affinity with oxygen and sulphur at a temperature of steel-making, but also with extremely strong to field trash shape
The control ability of state and size.For Al deoxidization steel, magnesium treatment, can be by steel while the dissolved oxygen in further reducing steel
In Al2O3 be mingled with and be changed into dystectic MgO Al2O3, because it exists in molten steel with solid-state, the mistake grown up without being polymerized
Journey, therefore, the size that its oxide is mingled with can be very tiny, and Dispersed precipitate is in steel.Research shows MgO present in steel
Al2O3 is mingled with size can be controlled within 5 μm, and the mechanical property to steel has no adverse effect substantially.Equally, magnesium is added to exist in steel
While further reducing sulfur content, sulfide exists in the form of tiny MgS or MgS-MnS in making steel, mitigates because of MnS folders
The miscellaneous influence that Steel Properties are brought.
Although the advantage to molten steel using magnesium treatment is protruded very much, due to magnesium elements own characteristic（Low melting point, 650
℃；Low boiling, 1080 DEG C；Vapour pressure high, 2.0Mpa is more than during 1600 DEG C of temperature of steel-making）, without effective magnesium addition side
Before method, in steelmaking process, magnesium treatment is carried out to molten steel and also there is very big difficulty.
