Crucible steel Wikipedia
Crucible steel is steel made by melting pig iron , iron, and sometimes steel, often along with sand, glass, ashes, and other fluxes, in a crucible InScrap magnesium removed from the aircraft is stripped of paints and coatings, cleaned and then melted inside a steel crucible at 675–700 °C As magnesium melts, there is the riskCrucible Steel an overview | ScienceDirect Topics

Cementation (metallurgy) Wikipedia
Cementation (metallurgy) Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface The process is often used to refine leach solutions Cementation of copper is a common example Copper ions in solution, often from an ore leaching process, are precipitated out ofThis process has been used, for example, in small oil drums and 500litre containers for ILW, and has been extended to ISO shipping containers for LLW The technology is being used in the immobilization of many toxic and hazardous wastes that arise outside the nuclear industry and has the potential to be used in many more casesTreatment and Conditioning of Nuclear Waste

General Steel Making The Cementation Process
The cementation process of making steel is also called the converting process This process consists in impregnating bars of wrought iron or soft steel with carbon, at a temperature below its melting point, and was used (chiefly in England) for the production of high carbon bars to be employed in the manufacture of crucible steel or shear steel2022年1月31日· LD Process LD Process is a Linzdonawitz process which is developed in Austria in 1949 In this method, a basic oxygen converter is used to make highquality steel in a relatively short time This method uses molten pig iron and steel scrap and oxygen is passed through a watercooled lance for the oxidation of carbon and otherManufacturing Process of Steel: 6 Methods of Making Steel
