What is ferrochrome?
Ferrochromium is made using metallurgical grade chrome ore and can be divided into three categories, depending on the level of carbon in the alloy.
The three types of ferrochrome alloys are:
High-carbon (HC) ferrochrome (carbon content between 4% and 9%)
Low- and medium-carbon (LC & MC) ferrochrome (carbon content less than 0.5% for LC and between 0.5% and 4% for MC)
Ferrochrome-silico-chrome (FeSiCr)
Ferrochrome applications:
Production of steel, especially stainless steel with chromium content of 10 to 20%, is the largest consumer of high-carbon ferrochrome. Over 80% of the worldâ??s ferrochrome is used in the production of stainless steel.
The vast majority of ferrochrome produced is� charge chrome, which has a lower chrome content ratio. Used most commonly in stainless steel.
Low carbon� and� medium carbon� ferrochrome is used in the manufacture of special steels. Low carbon ferrochrome can be used to produce superalloys.
INTRODUCTION:
Zircon sand, also known as zircon, is a mineral composed mainly of zirconium silicate (ZrSiO4). Pure zircon sand is a colorless transparent crystal.
FORM OF ZIRCON
ZIRCON SAND
ZIRCON POWDER
APPLICATION:
To be used in Ceramics. Opacity, whiteness, wear resistance and moisture resistance make it a key component of ceramic tiles, sanitary ware and tableware.
To be used in refractory industry to protect the interior of high-temperature furnaces
To be used in foundries and precision casting processes for the casting of metals and alloys into various products due to the thermal stability, high melting point and abrasion resistance provided by zircon.
Another important application is the production of a broad range of zirconia chemicals, which in turn, have a diverse range of end uses including ceramics, refractory, catalysts, coating electronics and biomedical related products.
Some zircon is used as an x-ray filter and as a polishing agent in the production of silicon wafers for the manufacture of semiconductor components such as integrated circuits (computer chips).

1. Ferro Manganese is an alloy of Iron and manganese, with manganese between 65.0%~90.0%, as deoxidizer and alloying element additive. Divided into furnace ferromanganese and blast furnace ferromanganese.
2. Main categories: high carbon ferromanganese (carbon 7%), medium carbon ferromanganese
(carbon 1.0~1.5%), low carbon ferromanganese (0.5% carbon), metal manganese, Spiegel, Silicon-manganese alloy.
3. International general standard for carbon ferromanganese containing mananese with 75 ~ 80%. To adapt to the conditions of low grade raw ore, China provides manganese lower grades (furnace ferromanganese manganese containing more than 65%, blast furnace ferromanganese manganese containing more than 50%).
Ceramic Foundry Sand with the high quality bauxite as the raw material, blowing into the ball after remelting smelting, is a new type of steel casting foundry sand.Itâ??s characteristic as high temperature resistant,small amount of thermal expansion, easy collapse, good renewable performance,good casting properties, received the recognition from the cast made experts domestic and overseas. Widely used in all kinds of casting method,sand casting, special casting( casting, solid type, evaporative pattern casting, ladle flow guiding sand and so on ).Also used for shot peening, low expansion of high-temperature coated sand producing. 200mesh-270mesh used for evanescent mode coating producing.
