B50A310 Silicon Steel

 

For silicon steel, silicon is a good deoxidizer for steel, which combines with oxygen to transform oxygen into stable SiO2 that is not reduced for carbon, avoiding the lattice distortion of iron due to oxygen atom doping. Silicon becomes solid solution in alpha iron to increase the resistivity, while helping to separate out the harmful impurities carbon. Therefore, the addition of silicon to iron containing impurities in general can increase the magnetic permeability, reduce the coercivity and iron loss. However, the increase in silicon content will make the material hard and brittle, thermal conductivity and toughness decline, the heat dissipation and mechanical processing is not conducive, so the general silicon steel sheet silicon content does not exceed 4.5%.

Electrical steel sheet tension
In the actual production process, the first time due to the thicker strip coil, allowing the use of large front tension, while the rear tension by the pickling tension constraints can not be too large, so as not to cause interlayer slip injury. After the next few passes after the tension is greater than the front tension, before and after the tension difference control in 30 kN below, than the tension < 60% σ S. Rolling process as far as possible to use large tension to ensure the stability of the rolling process, in order to obtain a good plate shape, roll shape, and reduce the unit rolling pressure. In actual production, after the tension is greater than the front tension is not easy to pull off, and the rolling force is reduced significantly, but after the tension is too large easy to slip phenomenon. The last sub tension is set to match the continuous annealing line uncoiling tension to ensure the smooth uncoiling of the continuous annealing line.
