Description
Technical field
The present invention relates to metallurgical technology fields, specifically, in particular to a kind of steel pin, steel slag particle steel automatic hot apparatus at
Type system and forming method.
Background technique
In the related technology, it is molten iron and steel scrap or pig iron that common converter, which makes steel main furnace charge, and steel scrap or pig iron are added
Amount is about the 20% of converter capacity.The raw materials such as particle steel, the steel pin that steel slag is selected cannot be directly added into converter, and the master of converter is added
Wanting drawback is：The particle volume of steel pin is smaller, lighter in weight, relatively expands, directly enters converter tapping quantity and do not increase, in production process
One final dusting of middle steel-making can be lost a part of tap；Material is more inside steel pin, and directly entering furnace can tap to subsequent
The structure that steel is influenced in journey, influence finished product quality (directly enter furnace as cupric is exceeded in steel pin material ratio can be made to increase, steel rolling
The oxidation of peeling and increase steel in the process.Such as the exceeded hardness containing manganese increases, because manganese content has no idea to roll in rolling process.Such as
Containing ironing, exceeded material is excessively crisp, and rolling process will cause the fracture of steel).
The general steel mill of particle steel does not enter converter directly, because particle steel particles are smaller and impurity component more (iron can only out
85% or so) it cannot sufficiently be dissolved after entering converter, and directly enter converter and be easy to produce explosive splash to be easy to cause security risk.
Above-mentioned raw materials are directly added into converter and generate biggish flame and splash, and waste is big, increases consumption, and exist simultaneously personnel and equipment
Security risk.
Steel pin raw material carries out cold moudling under room temperature.Steel pin cold pressing is blocking can directly to enter converter, but with cold pressing block because of steel
Pin magazine ingredient is more, can only at most add 15% or so of supplying furnace steel scrap weight.
Particle steel has no idea to be cold-pressed, and because not having merging point, in addition particle steel density is about 4 tons every cubic metre, does not do
Method compacting.The another general steel mill of particle steel is unwilling directly to enter converter, because particle steel particles are smaller and more (the iron out of impurity component
Can only 85% or so) enter converter after cannot sufficiently dissolve, and directly enter converter and be easy to produce explosive splash to be easy to cause safety
Hidden danger.It is general that sintering is added, and add people's sintering that can generate secondary pollution and repeat ironmaking and increase production cost before steel.
