High Carbon Ferrochrome, Ferrosilicon Chrome, and Low Carbon Ferrochrome Ferrochrome Smelting in Zimbabwe ZIMASCO and Zimbabwe Alloys represent more than 90% of Zimbabwe's FeCr smelting capacity [490K tonnes of FeCr product - approximately 6% of 2008 world production], Chromium is used principally as an alloying element in cast irons and ...
products namely High Carbon Ferrochrome (HCFeCr), Ferrosilicon Chrome (FeSiCr) and Low Carbon Ferrochrome (LCFeCr). Ferrochrome smelting is a labour and energy intensive process. The principal application for chromium is as an alloying element in cast irons and steels. It is a strong carbide-forming
The paper suggests suitable refractories for the production of ferro-alloys like ferro-chrome, ferro manganese, ferrosilicon and also low carbon ferro chrome products. Introduction Ferro-alloys are compounds of iron with other metallic or non-metallic elements. They are used as additives for introduction of special properties into steel.
(Ferro-Sim), was used to evaluate the effect of different chrome ores on the electricity consumption used to produce high carbon ferrochrome (HCFeCr) in submerged are furnace (SAF), which uses electric energy and is fed with raw materials of chrome ores, fluxes, reductant and electrode paste.
Ferrochrome is often classified by the amount of carbon and chrome it contains. The vast majority of FeCr produced is charge chrome from Southern Africa. With high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.
The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers and broken down to minus 15mm material. It then moves through a jigging plant where the chrome and slag are separated by means of gravity. The slag .
(Ferro Manganese, Ferro Molybdenum, Ferro Niobium, Ferro Boron, Ferro Titanium, Ferro Tungsten, Ferro Silicon, Ferro Nickel, Ferro Chrome) An alloy is a mixture or solid solution composed of metals. Similarly, Ferroalloys are the mixture of Iron with high proportion of other elements like manganese, aluminium or silicon.
Ferrochrome can be of two types based on the amount of carbon it has; low carbon Ferrochrome and high carbon Ferrochrome. Most of the Ferrochrome in the world market comes now from places like South Africa, Kazakhstan, India and Turkey. In these counties, the substance is produced in specialized Ferrochrome plants.

the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt. High-carbon and charge chrome alloys are generally produced in the conventional smelting process
Utilization of ferrochrome wastes such as ferrochrome ash and ferrochrome slag in concrete manufacturing ... The utilization potential of ferro- chrome slag .
the slag has to be higher than the metal smelting point, because metal is heated up by using slag liquid phase. The optimum smelting point has been practically noted between 1680-1720 °C. The composition of ferro-chrome slag in the phase diagram is shown in Figure 3. The proportion of quartzite in the charge mix controls the right slag ...

Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 °C and its main components are SiO 2, Al 2 O 3 and MgO. Additionally it consists of chrome, ferrous/ferric oxides and CaO.
Due to its high carbon, low residuals and minimal slag content beach iron provides significant value to steelworks and grey iron foundries. Beach iron pieces vary in size but generally have a maximum thickness of 400 mm, a maximum width of 750 mm and a maximum length of 1200 mm or 750 mm (depending on the amount of processing requested).
