LOI is a company in the Tenova Group that makes reheat furnaces for the steel industry. Their full name is Tenova LOI Italimpianti, and they are the leading global supplier of reheating and heat treatment plants for the steel, aluminium and automobile industries.

When iron is produced in a melt shop, it may initially be in the form of rough castings called ingots. Iron in this form is not directly useful for most applications because of carbon-related brittleness. To produce usable steel, the iron is taken to a finishing mill. The finishing mill re-heats the iron and rolls or shapes it into steel coils, bars, or other shapes. A special atmosphere is frequently used in a reheat furnace to impart specific properties to the steel.

Tenova LOI Italimpianti makes these types of furnaces. With more than 4,000 furnace installations, LOI Italimpianti is the name behind some of the largest, most technologically advanced, and most efficient reheating furnace plants in the world.
