Rolling furnaces are working at temperatures between 1200˚C and 1300˚C. The billet is used to roll the sheet. Such furnaces are generally push-type furnaces. When the refractor selections are made, the choice is made considering the resistance to temperature, the resistance to friction, the resistance to gas corrosion. Because of the energy costs in the current technologies are considered as a primary concern, insulation design is made according to the working temperature of the furnaces. Oxygen and internal pressure control must be done during the operation of the furnace. It is a very serious consequence of the uncontrolled oxygen ingestion of the metals in the hot environment. Due to the high production capacity of the daily production capacities of the producer companies, it causes serious damages. furnace and refractory life affect the direct costs of the firms. The correct project, correct refractor selection, correct isolation design and refractory assembly will enable companies to make a profitable production.

Hot-dip galvanizing furnaces operating at a temperature of 450 ˚C are processes in which zinc is melted in a special pot and dipped into metals. The surrounding of pot is heated homogeneously to warm the pot. The zinc in the hot pot is ready for use by melting. Liquid or gaseous fuels are used. The insulation is designed so that it will resist the energized heat and will not escape the heat energy. The refractory qualities that we will use when doing the heat treatment are as above.

Aluminum smelting furnaces are operating at 650 ° C. They are furnaces which should not be called by the heat of the medium. Burner temperatures are 1200 ° C. Furnaces are located in mining region. The aluminum chemical has high chemical and physical effects on the refractory. It is important to select the smelting refractories when making the selection. insulation details are important in terms of loss. Due to the fact that there are moving ovens, the refractory installation details are a matter of concern.
