Reheating furnace for steel rolling mill line is a device (an industrial furnace) that heats a material or a workpiece (generally a metal) to rolling forging temperature in the metallurgical industry.

Structure and composition

According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and heating section along the length direction.

The lower temperature of the feed end is the preheating section, and its function is to utilize the heat of the furnace gas to improve the thermal efficiency of the furnace.

The heating section is the main heating section, and the furnace gas temperature is high to facilitate rapid heating.

The soaking section is located at the discharge end, and the difference between the temperature of the furnace gas and the temperature of the metal material is very small, so as to ensure that the temperature of the section of the burden billet is uniform.
