Zimbabwe traditionally produces three ferrochrome products; 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],

The present invention relates to a process for producing low-carbon ferrochromium, Introducing scrap iron or ferrochrome into an electric furnace to produce a molten metal; Mixing molten chrome ore powder with a reducing agent powder containing no carbon to produce molten ferrochrome melted by a thermite reaction; And removing the slag produced by the thermite reaction.

A reduction of off grade Low Carbon Ferrochrome in terms of carbon can be reduced to less than 2. 0% contribution of the overall which translates to increased revenue from the product. 1. INTRODUCTION Low Carbon Ferrochrome (LCFeCr) is a specialized material whose production and quality must meet the stringent controls. Carbon quality is the ...

Low carbon ferrochrome is a primary alloying element in the production of stainless steel. The Mixing Method (Perrin and Duplex) processes are most commonly used for the production thereof. However, during the cocktailing step, process temperatures are extremely high, resulting in rapid deterioration of the ladle refractories and fuming of the ...

A ferrochrome manufacturing process is mostly conducted by the carbothermic reduction of chromite in an electric submerged arc furnace (SAF). In modern industries, one of the main ... LOW CARBON FERROCHROME 2. PROPERTIES OF FERROCHROME 3. USES AND APPLICATION 4. B.I.S SPECIFICATIONS

The invention provides a method for producing low-carbon ferrochromium by a microwave silicothermic process. The method comprises the following steps: uniformly mixing ferrochromium ore fines, silicochromium alloy powder and calcium oxide powder; then carrying out microwave heat treatment; and then, separating slag from metals, wherein the metals obtained are block low-carbon ferrochromium …

Medium, low and micro-carbon ferrochrome alloy are generally made of silicon-chromium alloy, chromite and lime. Desiliconization is refined with a 1500-6000 kV electric furnace. It is operated with a high alkalinity slag (CaO/SiO2 is 1.6 to 1.8). Low-carbon, micro-carbon ferro chrominum is also produced on a large scale by the heat exchange method.

Low Carbon Ferrochrome Production (LC FeCr) LC FeCr (Low Carbon Ferrochrome) is a ferro-alloy used to regulate the ratio of Chromium in steel production without Carbon and other unwanted ingredients. Due to high quality it is a reliable and economical alternative instead of metallic Chromium in Superalloy production.

The invention relates to ferrous metallurgy and can be used in Ferroalloy industry, specifically in the production of low carbon ferrochrome. Various methods for the production of low-carbon (refined) of ferrochrome in electric furnaces or spacegreat, allowing to obtain a low content of carbon in it, but they are inefficient and typically require the use of high quality materials.

Also, by preparing a ferrochrome alloy with less than 2 percent carbon by the vacuum reduction and simple melting process for feed to the AOD, the overall chromium utilization in the production of low-carbon stainless steels is increased from the current levels of 85 to 90 percent to greater than 98 percent.

Low carbon ferro chrome production process. There are two production methods for LC ferrochrome. 1. High carbon ferrochrome refining method. Refining high-carbon ferrochrome with chrome ore. To obtain low-carbon ferrochrome. 2. Electrothermal …

To obtain low-carbon ferrochrome. 2. Electrothermal method. Under the condition of making alkaline slag in the circuit, the silicon in the silicon-chromium ...

The importance of low carbon ferrothrome as such will continue to stay for few more years in our country although the total demand will be diminishing from 1983 onwards drastically. The low carbon ferrochrome is being produced in the world by various processes, namely :- 1) Perrin Process. 2) Duplex Process. 3) Simplex Process. 4) Triplex Process.

The use of low carbon ferrochrome and ferrosilicochrome for chromium addition was common practice until the 1960s, the vacuum argon decarburization (VOD) process being commercialized in 1964 and the AOD process in 1968. In 1972, the Creusot-Loire Uddeholm (CLU) refining process was developed.

The furnace method was evaluated as a potential improvement on the mixing method for the production of low carbon ferrochrome. The furnace method can provide significant savings in the operating cost, primarily due to a saving of 29%–47% in the energy consumption.
