Determination of evenness of mechanical strength for graphite electrodes Ⅱ

Determination of evenness of mechanical strength for graphite electrodes Ⅱ

The constant B=mX-Y ; the constant t0=expB ; After the above deformation, the corresponding data of the 2015 product is converted (see Table 2), get the graphite electrode products here. According to formula (6) into the converted value in Table 2, the product in 2015 corresponds to the Weibull modulus:m=14.3183; B=38.1340; t0=3.6424x1016,So the specific form of the Weibull mod... ...

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... ...
