An industrial furnace is a vital unit in the metallurgy and steel industries, responsible for heating billets to the required temperature for subsequent processes like rolling. The dimensions and capacity of these furnaces are precisely designed and built based on the size of the incoming billets and the desired production tonnage to ensure maximum efficiency.

Fuel and Temperature Control System
Fuel: The main fuels used in these furnaces are natural gas and fuel oil, which provide the necessary thermal energy to heat the product.
Final Temperature: The furnace's operating temperature reaches 1200°C, which is ideal for preparing billets for rolling.
Automation: The furnace system is fully automated and controlled by a PLC (Programmable Logic Controller). This smart system controls the flow rate of gas and air online and in real-time, keeping the internal temperature of the furnace at the desired, constant level and preventing temperature fluctuations.
Structural Materials High-quality refractory materials are used for the construction and insulation of the furnace to ensure its resistance to extremely high temperatures. These materials include:
1-Refractory Bricks: Various types, such as chamotte (aluminosilicate), alumina, insulating, and dry-laid bricks, are used for the inner and outer lining of the furnace.
2-Ceramic Fiber Blanket: A highly efficient thermal insulator used in various sections of the furnace to minimize heat loss.
3-Ceramic Fiber Board: Another type of insulating material that offers high thermal resistance and structural strength.

This combination of refractory materials and an advanced control system makes the furnace a highly efficient and safe unit, playing a key role in steel production processes.
