A good blast furnace burden consists, for the major part, of sinter and/or pellets (Figure 3.1, next page). Sinter burdens are prevalent in Europe and Asia, while pellet burdens are used more commonly in North America and Scandinavia. Many companies use sinter as well as pellets, a lthough the ratios vary widely.
This page is about the IndustrialCraft 2 Blast Furnace. For other uses, see Blast Furnace. The Blast Furnace is a machine added by IndustrialCraft 2. It is used to create Steel and Slag. To run, it must be given a source of heat, such as being placed adjacently to an Electric Heater. The initial heat draw is large, but the Furnace will require a small …
High silica (SiO2) content in the limestone used for sintering purpose is preferred since SiO2 counter the effect of alumina (Al2O3) in the blast furnace. The second major use of limestone is in steelmaking. It is being used for maintaining slag basicity (CaO/SiO2) of around 3. In steelmaking, limestone is used in calcined form.
Lead and Zinc Sintering | IntechOpen. 06-02-2013· 1.2. Why sintering. Lead and zin metals are produced in blast furnace. In a blast furnace, ore, coke and flux are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions …
Sintering happens in the metal manufacturing process. Sintering reduces waste and provides an efficient raw material for the blast furnace. Carbon is required for the blast furnace, and it is supplied in the form of coke. To make carbon, coking coal is heated in an oven, which drives off volatile by-products and leaves carbon.
In this work, real sinter and coke from the production site were used in experiments to investigate the reaction behavior of blast furnace raw materials in reducing atmosphere. To meet the requirements of the experimental equipment, the particle size of coke and sinter was less than 200 mesh.
Iron Ore is the most important raw material needed to produce steel. However, it cannot be used directly in the blast furnace. That is why sinter is created that helps convert iron into steel. Rashmi Metaliks has its own Sinter Plant set up at 2007 to have complete control over the quality of materials used in the steel production process.
Technology has been developed for the production of fluxed local sinter and pellets with residual carbon for blast-furnace use. The new products have better metallurgical characteristics than existing materials.
Sinter is the primary feed material for making iron and steel in a blast furnace, and is made by mixing iron ore concentrate with several additives (such as …

Blast furnace technology is a mature production system with literally a thousand-year history and fossil coke has unique desirable mechanical properties which makes it difficult to replace with less emitting alternatives. 22 Another commonly stated reason why steel is seen as difficult to decarbonize is the socio-economic inertia that …
The purpose of sinter are to be used converting iron into steel. Sinter plants, in combination with blast furnaces, are also used in non-ferrous smelting. About 70% of the world's primary lead production is still produced using the sinter plant–blast furnace combination,and this combination was formerly often used in copper smelting (at the ...
The entire quantity of coke breeze generally is consumed in sinter plant during the sintering of ore fines. Earlier there was practically no use of nut coke in an integrated steel plant and it was sold to other users. Prof. V. I. Loginov suggested in 1960s to charge the nut coke into the BF mixed with sinter.
