Ferrochromium slag is a waste material obtained from the manufacture of ferrochromium (FeCr). FeCr metal is produced in electric-arc furnaces by a physical-chemical process from the oxide of chromium ore with coke as the reducing agent at a temperature of about 1,500°C. Both the molten FeCr metal and the slag flow out into ladles.

Ferrochromium This alloy is used to increase tensile strength and yield strength of steels. With that, chromium increases hardness and wear resistance of carbon steels and confers stainless properties to low-carbon steels (with chromium content in them 12 % min). Ferrochromium is subdivided into 4 groups according to the carbon content:

Slag volume produced during the process is highly dependent on the quality of the charge materials used for the production process. The consumption of electrical energy is influenced by the slag volume. The higher is the volume of the slag higher is the requirement of the electric energy. The furnace feed typically consists of chromite ore (lumpy ore, pellets, and briquettes), reductants ...

Jun 16, 2021In this paper, aiming at the problem of chrome-iron separation in electroplating sludge, the separation of ferrochrome by complexation and precipitation with benzoic acid as complexing agent is achieved. The optimal conditions consisted of a 1: 3 molar ratio of Fe3+: C6H5COOH, a reaction temperature of 30°C, a final pH of 2.5 and a reaction time of 2 min. The separation rate of the iron was ...

Five different samples including different percentages of epoxy resin and ferrochromium slag were produced. X-ray, gamma ray, and neutron particle transmission experiments were performed for epoxy-ferrochromium slag composites. Also, FLUKA Monte Carlo simulations were made to obtain absorbed doses. As a result, radiation shielding performance increases with increasing ferrochromium slag ...
