fluxes for metallurgy - 911 Metallurgiststone, dolomite, and silica are widespread throughout the world, although there are examples where an adequate flux source was not available and this affected the process selection. Line and Dolomite. Line and dolomite fluxes used for ironmaking and steel- making in the United States originate primarily from.dolomite for steel making,Line and dolomite flux and their use in iron and steel plant .May 8, 2013 . Both line and dolomite are extensively used in an iron and steel plant in various processes and their use is explained below. Specification of line and dolomite for iron making is less rigid. But for steel making line should have very low silica (SiO2) and alumina (Al2O3) since these.

Dolomite - British Geological Survey

The principal uses of dolomite are those that utilise the mineral in the calcined form. (dolomitic lime). The most important of these is as a steelmaking slag flux, where the dolomitic lime replaces some of the quicklime (CaO) used in slag production. In addition to increasing slag fluidity, the presence of magnesia also helps to.

recycling of burned dolomite powder in steelmaking - Springer Link

Burned dolomite powder of particle size less than 5 mm is a significant MgO and CaO resource and is obtained directly as a solid waste in the steel industry. The recycling and use of this waste material is the only option to save non-renewable resources and to conserve scarce landfill space. This paper discusses.

Study on the dissolution of lime and dolomite in . - DiVA portal

`FeO´ come into the slag by oxidation, and CaO in the slag is due to the addition of different fluxes. In industry, lime and doloma are very important slag additives in primary steel making process. The dissolution of lime (or line) and doloma (or dolomite) into different slag systems has been the topic of many researchers.

Iron and Steel - The National Lime Association

In basic oxygen steelmaking, molten iron from a blast furnace is charged into a refractory-lined steelmaking furnace, and then oxygen is injected into molten iron at high speeds, resulting in oxidation of carbon and impurities. Lime is used in several steps in this process. Many steel plants desulfurize the hot metal externally.

Dissolution of Magnesite and Dolomite in Simulated EAF Slags

3. Introduction. Fluxes such as lime (CaO), magnesite (MgO) and dolomite (CaO•MgO) are used in EAF steelmaking. The slag is designed to: • Remove sulfur and phosphorus. • Reduce refractory wear and gunning. • Provide a forming slag for long arc operation. Refining for sulfur and phosphorus is favored by high basicity.

Dolomite - Wikipedia

Where calcite line is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic line are added to soils and soilless potting mixes as a pH buffer.

Tata Sponge Iron Ltd : Raw Materials

Hence, it is essential to examine the chemical and physical characteristics of raw materials, both individually and in combination. The basic raw materials for the production of sponge iron are iron ore, non-coking coal and dolomite. Several tests are conducted in the company laboratory to ascertain their suitability in a rotary.

Recycling practices of crushed MgO-C bricks and dolomite sinter .

Reduction of production cost on electric arc furnace (EAF) technology is strongly dependent on the efficiency of electrical energy introduced into the metal bath. Beyond EAF technology, the slag foaming process is currently applied to some other equipment for steel production aiming to save energy, productivity.
