Aluminum is formed at about 900°C, but once formed has a melting point of only 660°C. In some smelters this spare heat is used to melt recycled metal, which is then blended with the new metal. Recycled metal requires only 5 per cent of the energy required to make new metal.
Stainless Steel Grades (The Ultimate Guide) The following contents can give you a thorough understanding of the stainless steel grades, convenient for you to select proper stainless steel. Currently, the commonly used stainless steel is 304 stainless steel and 316 stainless steel. On the price basis, 304 stainless steel is much cheaper than 316 ...
Aluminum futures traded near $2,600 a tonne, the highest since June 2011 on higher demand and tight supply as China suppresses smelting to reduce pollution and meet green targets. Aluminum producers in Yunnan province were told to reduce power consumption and smelter Yunnan Shenho is set to miss its 2021 output target due to the power cuts.
sulphide ores and 70% oxide ores. Despite the relative abundance of oxide ores, 55% of nickel and nickel alloys produced today are derived from sulphide ores. However, with the production of nickel and its alloys from low-grade oxide ores becoming increasingly

The desulphurization behavior of stainless steel by using lime-alumina based slag has been studied on a laboratory scale.The sulphur capacity of the slag was calculated with the aid of FactSage software.Consequently,the equilibrated sulphur distribution was then calculated.The effect of the experimental conditions,such as slag chemistry,temperature and oxygen level of the molten steel on …
31-05-2012· Capability of a slag to remove sulfur from steel is characterized by the distribution coefficient of sulfur: L S = (S)/[S] Where: (S) - concentration of sulfur in slag; [S] - concentration of sulfur in steel; As appears from the above equations desulfurization is effective in deoxidized (low (O)) basic (high (CaO)) slags.
Thus, desulfurization (sulfur removal from liquid steel) is needed as a key process that is mainly achieved in ladles during secondary steelmaking. In Steel Desulfurization, several factors simultaneously effect the extent of sulfur removal from the molten steel: capacity/potential of the slag for sulfur removal; steel …
Nickel aluminium bronze has a cost approximately equivalent to that of basic grades of stainless steel. One disadvantage of this material is that it is more anodic than most materials, so that if a nickel aluminium bronze valve is coupled to a stainless steel pipe, then corrosion of the valve in seawater could be fairly rapid.
The Steel & Metal Manufacturing sector smelts and/or refines ferrous and nonferrous metals from ore, pig or scrap, using electrometallurgical and other process metallurgical techniques. Establishments in this sector also manufacture metal alloys and superalloys by introducing other chemical elements to pure metals. intermediate, and waste materials.

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
30-07-2016· Normally, lime (CaO), alumina (Al2O3) and slag deoxidizer are used to modify the ladle slag. For steel desulphurization it is important to reduce the mass content of FeO and MnO to a low level. The desulphurization process uses the following different steps. Slag adjustment with respect to (i) slag deoxidation, and (ii) lime saturation
Aluminum vs Steel Cost. Cost and price are always an essential factor to consider when making any product. The price of steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum (see galvanized vs stainless for more info on steel).
