Role of Slag in Converter Steelmaking IspatGuru

Aug 01, 2015 If the slag to steel mass ratio at the end of a converter blow varies within 0.08 to 0.1, the slag to steel volume ratio rises from almost zero in the beginning of the blow to 0.20/0.25 towards the end of the blow. In general, slag is considered to dampen metal ejections (spitting) and dust formation from the converter during the blow.

Steel Converter Slag as a Raw Material for Precipitation

Aug 01, 2008 In this work we study the possibility of utilizing steel converter slag, a byproduct of steel manufacturing, for production of pure calcium carbonate. The dissolution of calcium from steel converter slag by using acetic acid as a solvent and the precipitation of pure calcium carbonate from the resulting solution were experimentally investigated. It was found that, while strong solutions of

Steel converter slag as an oxygen carrier in a 12 MWth CFB

Sep 01, 2019 Steel converter slag, LD-slag, LD-stone or Basic Oxygen Furnace (BOF) slag is a by-product from the basic oxygen steel production process, also called Linz–Donawitz process. In this process, iron is converted to steel by the addition of fluxes, alloying additives and scraps under oxidative environment ( Roudier et al., 2013 ).

LIQUID-SOLID SEPARATION

Liquid-solid separation involves the separation of two phases, solid and liquid, from a suspension. It is used in many processes for the: 1. recovery of valuable solid component (the liquid being discarded); 2. liquid recovery (the solids being discarded); 3. recovery of both solid and liquid; or 4. recovery of neither phase (e.g., when a liquid is being cleaned prior to discharge, as in the

Solids Separation Air Management Practices Assessment Tool

Solid-liquid separation is the partial removal of organic and inorganic solids from animal manures. Solids separation creates two manure streams, a solids rich fraction that can be composted or anaerobically digested, and a liquid rich fraction that is easier to pump and handle. Solids separation reduces the amount of organic material remaining

Industrial Liquid Solid Separator & Solid Liquid Filtration

Mechanical solid liquid separation is an effective method to remove contamination and separate solid materials from liquid slurries. The solid-liquid filtration process involves a type of filter media, usually a metallic or synthetic mesh screen, by which suspended solids are removed from the liquid.

Liquid Solid Separation Equipment Liquid Solid

In Liquid Solid Separation, or Liquid-Solid Extraction, a solvent (hydrophilic or hydrophobic, acidic, neutral or basic) is added to a solid forming a slurry. Insoluble material can be separated by gravity or vacuum filtration, and soluble material is "extracted" into the solvent. A sequence of solvents, of varying polarity or pH, can be used

SOLID LIQUID SEPARATIONS IN PILOT- AND COMMERCIAL-

The first step in tackling the solid–liquid separation needs for a process is to define the requirements of the separation. Aside from the general scale of the proposed operation, the product phases must be defined; if both the solids and liquids are to be collected, the choice of available technologies may be somewhat limited.
