Explore of carburization behavior of low-carbon steel during smelting process

Explore of carburization behavior of low-carbon steel during smelting process

From the argon bottom blowing flow rate and bottom blowing angle, it can be seen that the bottom blowing flow rate and bottom blowing angle of argon also directly affect the fall of the graphite electrode hole wall, and the he mass of electrode hole wall shedding is > 4 kg. As the ferroalloy and refining package walls are less carbonized, they are not considered in the fault tr... ...
