Dolomite for use as flux in steel metallurgy should be hard, compact and finegrained so that it can stand the burden of the batch in the blast furnace as well as the basic steel convertor. It should not be crystalline, , it should not have a saccharoidal texture which gives fritting effect in the furnace.
I built a big blast furnace a while ago, based on Landschaftspark DuisburgNord (Germany) and Horno Alto 1 de Altos Hornos de Vizcaya (Spain), and quite a few people asked for instructions to build it. That model has about 13k bricks, far too much for LEGO Ideas, so I decided to make a smaller ...

Sep 30, 2015· As a result of experimental studies, dolomite used instead of cement caused up to mm expansion. The results are in accordance with the values indicated in the standards. As a conclusion, it is possible to use blastfurnace slag in balancing the expansion properties of dolomite.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitzsteelmaking or the oxygen converter process is a method of primary steelmaking in which carbonrich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into lowcarbon steel.
Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than mm (No. 4 sieve) in diameter to dense, sandsize grains passing a …

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". 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.

A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing "scaffolding" and improving the operation of the blast furnace.
Blast Furnace Size. Larger blast furnace, use of better prepared burden, recovery of waste energy, and maximum recovery of slag characterize the iron making technology proposed for VSP. The largest blast furnace in India at that time was of 2000 m 3. Compared to this, elsewhere furnaces up to 5070 m 3 had been built.
