Abstract: The magnetic properties of steel of a structural element of an aluminum reduction cell have been investigated in the temperature range of $300$—$900$ K. The analysis of the temperature dependence of the saturation magnetization $M_S(T)$ showed (i) the applicability of the Bloch's $3/2$ law and a reasonable value of the Bloch's constant for steel and (ii) the quadratic dependence $M_S(T) \mathtt{\sim} (1-T^2)$ in the temperature range of $380$–$700$ K.
Keywords: steel, aluminum reduction cells, saturation magnetization, Bloch's constant.
