Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Electroslag remelting (ESR), also known as electro-flux remelting, is a process of remelting and refining steel and other alloys for mission-critical applications in aircraft, thermal power stations, nuclear power plants, military technology, etc.. Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. How to use slag in a sentence. … The layer on top of your weld left after you have welded. Basic slag definition: a furnace slag produced in steel-making, containing large amounts of calcium phosphate :... | Meaning, pronunciation, translations and examples Slag needs to be removed so that you can; 1. 2) - a woman whom sleeps around, looks cheap &/or has questionable character. Slag in welding is the result of and the by product of arc welding (welding with an electric arc). 1) - to spit. Slag is a by-product of the steel-making process, produced as impurities are separated from molten steel in mill furnaces. The electroslag remelting (ESR) process is used to remelt and refine steels and various super-alloys, resulting in high-quality ingots. Slag is a coating. Welding Slag is formed by metal oxides and other chemical compounds. Slag meaning a female prostitute seems to have first developed much later - around the 1950s - and its more general application to loose girls or women is later still, 1960s probably at soonest. Concrete made with recycled steel slag is 17 percent stronger than traditional concrete. 3) - the waste product of the steel making process. CHEMICAL PROPERTIES: At the end of the process, the main components of the slag are iron oxide, calcium oxide, and silicon dioxide. So the notion that slag came directly from the iron and steel industry to the loose woman meaning … Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide. Iron and steel slags are coproducts of iron and steel manufacturing. STEEL SLAG DEFINITION AND DESCRIPTION OF SLAG: Steelmaking slags are the by-products of the processing of iron and scrap with lime into the desired type and grade of steel in furnaces such as the basic oxygen [BOF] and electric arc [EAF] furnaces. Slag is not a random product, but rather a consequence of the Linz-Donawitz process, which uses steel as well as LD slag. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the Slag definition is - the dross or scoria of a metal.
