HORIZONTAL VS. VERTICAL FURNACE INSTALLATION | CoolBreeze

Apr 25, 2019 · DOWN-FLOW VERTICAL FURNACE. In a down-flow furnace, the cold air is drawn from the top and expelled as warm air out of the bottom of the unit. A down-flow unit is generally installed in the home's attic, and tends to be less energy efficient. In some homes, a down-flow furnace is the only option due to space constraints.

Carburization | Inspectioneering

Carburization involves the absorption of carbon into steel or alloy during operation in a high temperature environment, typically above 1100F (593C). Carbon from the carborizing environment enters the surface of the steel by diffusion, causing the metal to become embrittled and lose creep resistance and toughness.

Carburizing - Wikipedia

Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.
