What metals are extracted using a blast furnace?

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the

Carbon Brick for Blast Furnace

Ordinary blast furnace carbon brick is used to build medium blast furnace with low smelting strength and 1000~2500m3 volume. The carbonaceous product is a refractory product made of coal tar pitch as a binder by heat-treating anthracite or coke and graphite as

Blast Furnace: Introduction, Definition, Construction,

Moreover, if blast furnace is used with biomass, PCI can be substituted fully by charcoal which will be merely 45% of the carbon input. When blast furnace gases are released they are improved and recovered which also helps in saving energy by 35% MJ/t-HM to 70% MJ/t-HM.

How to Choose Refractory Bricks Used for Different Parts

How to choose refractory brick used for different parts of blast furnace? When choosing refractory brick used for different lining parts of blast furnace, we should follow some principles. The refractory lining of every part should fit the parts thermal current intensity, so that the lining can maintain previous vertebral shape and stability under the impact of strong heat flux.

Effect of Carbon Aggregates on the Properties of Carbon

The effect of carbon aggregates on the carbon refractory properties for a blast furnace was studied with X-ray diffraction (XRD), scanning electron microscopy (SEM), an energy-dispersive X-ray, mercury porosimetry, a resistivity instrument, and a laser thermal conductivity meter. The results showed that the microporous structure of a sample was determined by the amount of β-SiC whiskers. The

RS is a Carbon Bricks manufacturer, If you are in need of carbon bricks price, please click to Contact RS Refractory Company.

Best Blast Furnace Refractory For Sale In Rongsheng

Blast furnace refractory for sale in Rongsheng manufacturer is used to build refractory lining in blast furnace for resisting high temperature and all kinds of chemical and mechanical erosion. In order to prolong the furnace life, it is necessary to choose refractories used in blast furnace reasonably according to the volume and the service properties of blast furnace.

Refractory

A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures.[1] Refractories are polycrystalline, polyphase, inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides or non oxides like carbides

Advanced carbon refractory blocks for hearth wall lining:

The state of the refractory lining in the lower 'liquid' part is still the lifetime-decisive factor of a blast furnace, under normal circumstances. Repair work in the hearth is usually combined with a total blow down and emptying of the furnace. The wear of the lining in this
