for hot metal desulphurisation externally. Ladle based hot metal desulphurization is done with the help of reagents like magnesium, carbide based compounds and lime. Different types of External Desulphurization techniques are used nowadays and are frequently adopted by the steel makers. Some of the important techniques are mono-injection, co-

A Review of Modelling Hot Metal Desulphurisation - Visuri ...

Hot metal desulphurisation serves as the main unit process for removing sulphur in blast‐furnace based steelmaking. This study reviews the available body of literature on modelling hot metal desulphurisation to provide an in‐depth analysis of the approaches employed and results obtained.

Steel and hot metal desulphurisation - m-tec powder

The hot metal desulphurisation (HMD) is conducted typically in a ladle or a torpedo car. In the lance injection process, the desulphurisation reagent is injected pneumatically through an immersed lance [1–2] as show in Fig.1. The objective of this work was to develop a mathematical model, which can

Jul 30, 2016· Process of desulphurization. Primarily, there are two options available for the removal of sulphur from the liquid steel. These are (i) by means of metal-slag reaction, where the top slag is mixed intensively with the liquid steel, and (ii) by injection of metallic calcium (Ca) into liquid steel, where a precipitation of sulphides occurs.

Optimization of Desulphurization Process using Lance ...

hot metal desulphurisation (HMD) process. Typically, during the slag skimming, more than half of the removed material is iron rather than slag. This means that, depending on the process scale, 500–3000 kg of iron is removed per heat. On an annual basis, millions of euros worth of iron is skimmed

For the hot metal desulfurization in the transfer and the torpedo ladles AlzChem offers highly effective products. Our various CaD mixtures are based on finely ground and homogenized Calcium Carbide. Depending upon customers' demand, different agents are added such as volatiles or slag modifiers to reduce iron losses. Magnesium is injected together with CaD and/or Lime in

Hot Metal Pretreatment can Lower Impurity Content

Hot metal pretreatment is a process which is performed after the tapping of a blast furnace (BF) and before decarburisation in a basic oxygen furnace (BOF). In most cases, this process lowers the impurity content of hot metal. Hot metal desulphurisation, de-siliconisation, and de-phosphorisation are processes that are included in this category.
