Industrial Ferrochrome Manufacture
Raw Material Requirements For Making High Carbon Ferrochrome
The gas and non-metallic inclusion content in the molten iron not only affects the strength of high-carbon ferrochrome and the density of castings, but is also related to the formation of defects such as pores and cracks in castings.
Nitrited Low Carbon Ferro Chrome
With the continuous development of society, more requirements have been put forward for the production of ferrochrome. The production technology of ferrochrome manufacturers also needs to be continuously improved to produce high-quality ferroalloy products. In this regard, high-carbon ferrochrome manufacturers need to improve their control over the pouring temperature of molten iron. Under normal circumstances, the exit temperature of molten iron is at least 500C higher than the pouring temperature. However, according to different needs and products produced, high-carbon ferrochrome manufacturers need to have more accurate control of temperature.

However, it is important to know that the rate of chromium reduction in the ferrochromium smelting method is low because the silica chromium ore contains 30-35% Cr2O3 and 10-20% Si02. At smelting temperatures, silicon oxide forms a sticky film on the surface of the chromium ore blocks, which prevents the interaction of the chromium oxide with the carbon reducing agent and gaseous carbon monoxide. The silica flux enhances the silica oxide effect of the chromium ore by hindering the contact of the ore chromium spinel with the carbon reducing agent and gaseous CO. Due to the passivation reaction of chromium reduction from chromium spinel, it is not reduced in the upper layers of the furnace bath. Solid ore particles are supplied to the bottom layer in considerable quantities and are entrained by the liquid slag flowing out of the furnace.

Detailed Description Of Ferrochrome
Ferrochrome is a kind of ferroalloy which mainly composed by Iron and Chrome,It's one of the basic alloying constituent for steel industry.It can markedly improve the steel's oxidation resistance and corrosion resistance .Add the ferro chrome when steel making can produce various special steels with high intensity,resistance to corrosion,wear-resisting,high temperature resistance and oxidation resistance like stainless steel,acid-resisting steel,heat resistant steel,ball bearing steel,spring,steel and tool steel and etc.Ferrochrome contains 55%-75% chrome according to different carbon content can be divided into High-carbon (4%-10%C), Middle- Carbon (0.5%-4%C), Low-Carbon (0.15-0.5%C).Micro-Carbon (<0.15%C).High carbon ferrochrome can also be called carbon ferrochrome, middle carbon, low carbon and micro carbon can also be called refined ferrochrome.
