Steel - Ladle metallurgy Britannica
Steel - Steel - Ladle metallurgy: The carrying out of metallurgical reactions in the ladle is a common practice in practically all steelmaking shops because it is cost-efficient to operate the primary furnace as a high-speed melter and to adjust the final chemical composition and temperature of the steel after tapping. Also certain metallurgical reactions for reasons of equipment design and
Characterization of Tool Wear in High-Speed Milling of
In this experimental study the cutting performance of ball-end mills in high-speed dry-hard milling of powder metallurgical steels was investigated. The cutting performance of the milling tools was mainly evaluated in terms of cutting length tool wear and cutting forces. Two different types of hardened steels were machined the cold working steel HS 4-2-4 PM K490 Microclean/66 HRC and the

Metallurgical process - DRDGOLD
In essence the new technology was successful in liberating more gold and increasing recoveries but it masked the metallurgical instability and inefficiencies downstream in the existing part of the circuit. Thus the gains in one area were being lost elsewhere and the same amount of gold was being produced at a higher cost.

Currently many mines have no option but to ship arsenic-bearing concentrates to smelters often on the other side of the world and incur the associated penalties.
Metallurgy - Wikipedia
Quenching is the process of cooling a high-carbon steel very quickly after heating thus "freezing" the steel& 39;s molecules in the very hard martensite form which makes the metal harder. There is a balance between hardness and toughness in any steel; the harder the steel the less tough or impact-resistant it is and the more impact-resistant it

What You Should Know About Metallurgical Coal
Metallurgical coal differs from thermal coal used for energy and heating by its carbon content and its caking ability. Caking refers to the coal& 39;s ability to be converted into coke a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker.
