We introduce the study of \textit{randomly oriented divisor graphs}. For each $ρ\in [0,1]$, the randomly oriented divisor graph $\mathcal{D}_ρ(N)$ is obtained from the divisor graph on $\{1, 2, \ldots, N\}$ by directing each edge according to divisibility and independently reversing the direction of each edge with probability $ρ$. We study the expected size of the largest strongly connected component, $\textbf{E}[\#Φ(\mathcal{D}_ρ(N))]$. Our main result gives a lower bound for this quantity in terms of the distribution of values of the divisor function $τ(n)$. As a consequence, we show that for any fixed $ρ\in (0,1)$, the largest strongly connected component has expected size asymptotic to $N$. To obtain explicit bounds, we prove an effective version of a theorem of Hardy and Ramanujan on the normal order of $\log τ(n)$, which may be of independent interest.
