Sep 08, 2020 · Blasting hot air into the mixture from the bottom causes it to ignite, producing CO and raising the temperature of the lower part of the blast furnace to about 2000°C. As the CO that is formed initially rises, it reduces Fe 2 O 3 to form CO 2 and elemental iron, which absorbs heat and melts as it falls into the hottest part of the furnace. Basic oxygen process metallurgy BritannicaBasic oxygen process (BOP), a steelmaking method in which pure oxygen is blown into a bath of molten blast-furnace iron and scrap. The oxygen initiates a series of intensively exothermic (heat-releasing) reactions, including the oxidation of such impurities as carbon, silicon, phosphorus, and

Vacuum Ingot Casting Basic Principle:Scatter the steel stream into droplets within a vacuum chamber producing a large surface area for gas removal Pouring from top! Vacuum Ingot Casting (Ladle to Mould) Casting directly into moulds placed in a vacuum vessel Most important stream degassing process today Combination with ladle stream degassing possible Metal Melt & Pour:Life of a Casting Reliance FoundrySome ladles pour over the top lip, or a pour spout, and need to be tilted:these often have gears that allow the foundry worker to carefully control the rate of pouring. Other ladles have their pouring spout at the bottom of the bucket and the pour is controlled by removing and replacing a plug.

Oxygen and lime bottom blowing metallurgy Britannica

Other articles where Oxygen and lime bottom blowing is discussed:basic oxygen process:in North America and the OBM (from the German, Oxygen bodenblasen Maxhuette, or oxygen bottom-blowing furnace) in Europe. In this system, oxygen is injected with lime through nozzles, or tuyeres, located in the bottom of the vessel. The tuyeres consist of two concentric tubes:oxygen and lime are Paper title:State of the Art in the Control of Inclusions Aug 22, 2005 · Bottom pouring is better, especially for intensive deoxidation, high superheat, low-speed casting and casting in a nonoxidizing atmosphere. The typical process from steelmaking to steel refining to bottom-poured ingot casting is given in figure 2 [10, 11]. During Pouring of Metal Article about Pouring of Metal by The In bottom pouring, several molds (from two to 60) can be filled with steel simultaneously. Here, the molds are mounted on a stool having channels lined with refractory brick. The steel from the ladle descends through the fountain into the channels of the stool and then enters the mold from the bottom

In a different procedure, called bottom pouring, as many as six ingot molds stand on a single large and thick bottom plate with several pipelike refractory runners installed on its top surface. These runners connect the molds to a refractory-lined, funnel-shaped
