Lime Calcination Plant Lining
Lime Calcination Plant Lining
The steel melt is transported in and refined by steel ladles, which are made of
refractories and steel-making materials. Refractory Lining prevents heat loss from the steel shell by
shielding it from the steel melt. A well-lined steel ladle improves steel quality and production by
providing effective temperature control of the steel melt.
Using finite element (FE) methods, substantial research has been done on the thermomechanical behaviour
of steel ladle linings with respect to pertinent process parameters, material characteristics, and
lining configurations. Learn more about Refractory Eractors services provided by us through our website

Lime Calcination Plant for Use in Steel Plant
Lime is a multipurpose substance. Lime is utilised in environmental, metallurgical, building, and chemical/industrial applications, among others. The most common application of lime is in steel manufacture, where it is used as a flux to remove impurities (silica, phosphorus, and sulphur) during steel refining. Lime is most commonly employed in environmental applications, where it is utilised to clean flue gases, wastewater, solid waste, and drinking water.
Lime is a white crystalline solid with a melting temperature of 2572 degrees Celsius. It is a basic oxide utilised in different smelting procedures to react with acidic oxides (such as silica). It produces milk of lime with water, which neutralises acidic wastewater. Other names include quick lime, lime flux, unslaked lime, and fluxing lime. Lime Calcination Plant Lining refers to lime that contains some MgO (typically 2% to 4%). Lime absorbs moisture from the air because it is a hygroscopic substance. It loses its reactivity and becomes hydrated when it absorbs moisture.
Lime is calcium oxide (CaO) created by heating limestone (CaCO3) to temperatures of 900 degrees Celsius or higher (usually 1100 deg C).
CaCO3(s) + heat = CaO(s) +CO2(g)
This response can be reversed. Calcium carbonate is formed when calcium oxide combines with carbon dioxide. The flushing of carbon dioxide from the mixture as it is released drives the reaction to the right.
Hydrated lime [Ca(OH)2] is formed by the reaction of lime with water (slaking).
CaO + H2O = Ca(OH)2 + heat
Slaked lime is another name for hydrated lime. It appears as a dry white powder. Hydrated lime is a kind of alkali that is used to neutralise acidic solutions.
Normally, lime is hydrated first and subsequently transformed into calcium carbonate by the action of CO2. The lime cycle refers to the process of calcination and conversion back to calcium carbonate. Read on and learn more about Lime Calcination Plant Process.
The production of basic sinter, desulphurisation, slag formation to remove impurities in basic oxygen furnaces (BOF) and electric arc furnaces (EAF), secondary steel production, neutralisation of waste acid liquors, and water treatment are just a few uses for lime and dolomitic Lime Calcination Plant Lining Process in the steel plant. The treatment of stack (flue) gases is an emerging use for lime. These gases' sulphur oxides are absorbed and neutralised by lime.
To aid in the material's binding, increase the sinter machine's productivity, and produce stronger sinter, finely Lime Calcination Plant Lining is typically added to the sinter mix in sinter plants.
The most widespread usage of high calcium and dolomitic lime is as a flux in BOF and EAF steel refining. Phosphorus, sulphur, silica, and to a lesser extent, manganese may all be removed with lime. Lime is also utilised extensively in the production of steel products and the secondary refining of steel.
Lime Calcination Plant Process is used in secondary steel-making processes like ladle furnaces and vacuum degassing, among others, to carry out critical tasks like fine-tuning steel chemistry, lowering the oxygen content, reducing the inclusions trapped by the slag, adjusting steel temperature, removing additional impurities, and preventing impurities from slags from reabsorbing. Lime can also be combined with other substances, such as fluorspar or alumina, to create a synthetic slag used as a flux to remove extra phosphorus and sulphur after the initial steel-making process. Lime Calcination Plant Lining Process is used in the AOD (argon oxygen decarburisation) process to produce stainless steel.
In downstream industries and iron and steel factories, hydrated lime has a variety of other uses. It is frequently used in pig casting machines where the moulds are given a lime whitewash coating to avoid sticking. The waste pickle liquid, which contains sulphuric acid and precipitates iron salts, is neutralised by hydrated lime. Steel goods are frequently given a Lime Calcination Plant Process after pickling to remove any remaining pickling acid sticking to the steel.
Lime Calcination Plant Lining is frequently used to neutralise the acid in coke by-product factories and to give steel items short-term corrosion protection in the form of a whitewash coating. It is a lubricant in wire drawing units where steel rods or wires are dragged through dies.
- The input and outflow portions of the kiln have been built differently based on the characteristics of limestone and its calcination requirements
- Uniform heating of the limestone, a slow rate of calcination, and too much calcination are appropriate for the high-activity lime used in steel production
- Its precise construction can effectively increase preheating effect, and its pre-heater has little pressure loss
- Effective Waste Heat Reuse: The two sides of the dependable rotary kiln are sealed by integrated scales, reducing air leakage to < 10%.
