Blast Furnace - HarbisonWalker International Refractory ...

The blast furnace process has been the primary method for producing iron for many decades. The blast furnace is a refractory-lined circular shaft 100 to 200 feet high, with an internal diameter between 20 and 45 feet. The refractory wall lining typically measures two feet or more in thickness and contains more than 2,500 tons of refractories.

The Basics of Brick and Refractories for Ferrous Foundries ...

Refractory and brick materials are needed to line huge shaft-like blast furnaces in which the molten pig is formed. The auxiliary furnaces or hot blast stoves, which heat the air for the blast furnace, are also lined with refractories. The molten pig iron from the blast furnace is then sent to a brick- or refractory …

Refractories: Properties and Types | Engineering

Refractory Fibres: These are made from high purity alumina and silica grains melted in electric furnace and blasted by high velocity gases into light fibres. Ceramic fibres are available in the form of felts, blocks and blankets. The heat losses through ceramic fibres are low compared to other refractory materials.

Shaft Furnace - an overview | ScienceDirect Topics

Shaft furnace typical of that used by MIDREX and HYL for gas-based production of DRI. Hot reducing gases from reformer may be trimmed by additions of oxygen and/or natural gas. Reducing gas enters shaft furnace around the periphery at the bottom of the reduction zone through a bustle pipe that distributes the gases evenly.

Product Profile: Enhanced Silicon Carbide Refractories ...

Apr 01, 2013· In refractory applications, the oxidation of silicon carbide leads to volume and linear expansion, which, if severe enough, can result in cracking and failure of the refractory products. As is the case with many materials exposed to air, silicon carbide forms a very thin passivation layer of silica on grain surfaces, even at room temperature.
