As the name suggests, PCI entails the injection of large volumes of pulverized coal into the blast furnace as a supplemental carbon source to facilitate the production of hot iron. It serves as a fuel and a reducing agent in a blast furnace, and for this reason, it is often used as a replacement for metallurgical coke.

Carbon Steel vs Stainless Steel | Metal Casting Blog

The carbon leaves the converter as a gas, carbon monoxide, which can, after cleaning, be collected for re-use as a fuel. During the 'blow', lime is added as a flux to help carry off the other oxidized impurities as a floating layer of slag.The quantities of scrap, hot metal and lime and other fluxes are calculated to ensure the correct steel temperature and composition.

Another strategy is to just plan on replacing the rod (rather than inspecting only). Anode rods aren't very expensive when compared to the labor to access it. If you stay on top of the anode rod you may find you never need to replace that tank. But if you DO need to replace your indirect, I'd highly recommend a stainless steel model. Delete
