Background
In the metallurgical industry, a furnace is a device (industrial furnace) that heats a material or workpiece (typically a metal) to a rolling-to-forging temperature.
The heating furnace is applied to various industrial fields such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmacy and the like. The heating furnace includes a continuous heating furnace, a chamber heating furnace and the like. The heating furnace for heat treatment of metals is also called a heat treatment furnace. A furnace that heats or homogenizes the temperature inside a steel ingot before initial rolling is called a soaking furnace. In a broad sense, the heating furnace also includes a soaking furnace and a heat treatment furnace.
In forging and rolling production, the billet is typically heated in an oxidizing atmosphere of a complete combustion flame. The metal is directly heated by adopting incomplete combustion reducing flame (namely self-protection atmosphere), so that the aim of no oxidation or little oxidation can be fulfilled. This heating method is called open flame or open flame type non-oxidizing heating, and is successfully applied to rotary hearth furnaces and chamber furnaces.
