Examples herein generally relate to sinter blend compositions for use in a sintering process that do not contain coke breeze (0.0% coke breeze), or contain only very small amounts of coke breeze. In particular, these sinter blend compositions are capable of repurposing mixture of iron-making reverts, having high total and metallic iron levels that re-oxidize so as to become a replacement fuel source for the coke breeze typically used in sinter blend compositions for use in a sintering process, while still managing to produce a sinter with sufficient ISO tumble strengths.

Computer modelling methods and foundry methods for copper-nickel coolant pipes cast-in-copper coolers are combined. First, Computational Fluid Dynamics and/or Finite Element Analysis steps verify geometric computer aided design models and materials choices, point-by-point heat distribution, and heat flows. And second, casting steps to commit an acceptable last thickness iteration of a thermal buffer part in simulation to casting it in a foundry. In the foundry, casting conditions are empirically developed to yield all but slight, unclustered bonding imperfections at a concentric diffusion interface of the pipes and surrounding solidified casting that improve the thermal conductivity of furnace-block coolers that incorporate coolant pipes. The combined methods verify in simulation that operational thermal stresses at the pipe-casting interface stay in-bounds of material stress limits, and that the peak temperatures on the hot face do not rise above 450 C.
