disposal of slag from blast furnace

Disposing Of The Slag - ChestofBooks

In the early days of the blast-furnace the slag was handled as clinker or ashes, and this method of procedure survived until very recent times in the crane-operated shovel, fork, etc., which I have described in a previous chapter as adjuncts to charcoal furnaces in the seventies and which were used to clean out and "work down" the furnace very much as we find it necessray to do with the ...

What is Blast Furnace Slag? - Definition from

2020-12-14 · Blast furnace slag is a non-metallic residue usually obtained from steel plants or from the reduction of ores in a blast furnace. It is used as a mud cake modifier for the cementing of oil and gas wells.. It has been found that using a slag mix for cementing is beneficial economically and technically as well as better for the environment than Portland cement.

Blast Furnace Slag - an overview | ScienceDirect Topics

Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace. Usually, it is rapidly cooled to a glassy state and ground for use in construction materials (Provis et al., 2015). By the step of water quenching and out of rapid decrease in temperature, most of the ...

Recovery of Titanium from Blast Furnace Slag |

2019-5-26 · Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate 2.7%. Because of the low level of titanium in slag, the best method of extraction is hydrometallurgy. In this study, parameters such as slag particle size, temperature, concentration of acid, solid-to-liquid ratio, and ultrasonic wave time were used to determine the

Slag Cement Questions

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.
