$Blast Furnace Refractories - Resco Products$

Blast Furnace

Blast furnaces are like regular furnaces lined with refractory to withstand the high temperatures and the abrasive materials being processed. The refractory lining's properties are enhanced through cooling to protect the refractory lining from excess heat.

Blast furnaces reduce iron ore through a process combining coke and limestone. This is a hot blast process whereby hot preheated gases from the blast furnace stoves are injected into the bottom area. Processing through a series of tuyeres connected to a bustle pipe. The combination of temperature and carbon monoxide reacts with the iron ore reducing iron oxide into liquid iron.

The iron settles to the bottom of the blast furnace and is removed from the furnace via a taphole. The limestone provides the basis for slag that is formed to trap the impurities generated. This process and this material are removed from a tap hole as well located above the iron tap hole. Due to the extremely reducing nature of this process, refractory products must be very stable in all-respects chemically and structurally.

Refractories for Blast Furnaces

Resco's line of blast furnace refractory products have the chemical purity and mineralogy and are fired to temperature to ensure to achieve the needed properties. Typical brands are Krial 50-A, Krial 60, Krial 60-A+, and Krial 65-A for their alkali, creep, and thermal shock resistances.

Dry Mortar

Metaldam

METALDAM® is a finely ground, 50% alumina, heat-setting mortar, highly refractory to 3100ºF and recommended for use where brick and mortar come into contact with molten metal or slags. Since it is more refractory than most firebrick, it not only resists erosion, but also helps to retard brick scouring. It holds brick firmly in place, yet will release them readily during tear out of the wall or lining for repair or replacement.
