Raw material management in a foundry is very important and effective. It contributes a lot to the total energy consumed in a foundry, especially melting energy. So a cost conscious approach in the usage of raw materials is necessary.
High energy costs have a negative impact on the survival of foundries, which are important for regional economic recovery and the future of skilled industrial workers.
Chromite is a metallic oxide mineral and the principal commercial source of the element chromium. It occurs in igneous, metamorphic and sedimentary rocks. Chromite is resistant to ordinary corrosion and is used as a protective coating for other metals.
Chromium is also an essential raw material for the production of stainless steel, gray cast iron and iron-free high-temperature alloys. It is also used in refractory and metallurgical industries.
Chrome ore is the basic raw material for magnesia chrome or chrome magnesite bricks and compounds used in the refractory sector, as well as premium moulding sand in foundries. The ore is subdivided into strong, friable, pulverized and silicified ores according to the physical state of chromites (strong –
We are aware of two incidents in which vessels carrying chrome ore concentrate liquefied on passage. As a result we recommend that Members only accept cargo when the Cargo Declaration shows satisfactory TML and moisture content percentages and can testing is performed by the Master on load out.
Coke is the solid by-product of coking coal processing. It is used in blast furnaces to make iron and in cupolas at foundries to melt iron, copper, lead, zinc, tin and other metals. It is also used as fuel in petrochemical processes to produce acetone and gasoline. Coke is also used to heat houses and commercial buildings.
The global foundry coke market is expected to witness lucrative growth during the forecast period. The growing construction activities across the globe are expected to boost the demand for steel, which in turn will propel the market growth.

In the foundry industry, sand is mainly used as mold and core sand in the production of cast iron and nonferrous metal castings. The raw sand is mixed with different types of molding sand binder to obtain specific casting properties.
The most common raw sand is natural siliceous sand which has good high temperature performance. When the sand needs better thermal insulation and higher strength, special sand such as zircon sand and chromite sand can be used.
Spent foundry sand is also often used in road construction. It has been shown that when properly used, compacted spent foundry sand provides adequate support for flexible pavement design and can yield significant cost savings. EPA has released a risk assessment and state toolkit for developing beneficial reuse programs for spent foundry sand.
Ferro silicon is produced in blast furnaces or electric arc furnaces by reduction of silica with coke in the presence of iron. Its silicon content is variable and can range from 15% to 90%; the rest of it consists of iron silicides with smaller amounts of calcium and aluminium.
Its major use is as a strong steel deoxidizer. It removes oxygen from the melt, thus preventing formation of inclusion-forming oxides and other impurities in the final product.
It also acts as an effective alloying element and can increase the overall impact resistance of the final steel product. The metal can be delivered in lump form or as pre-formed briquettes. Microtrac analyzers are ideally suited for analyzing this granular material, including its varying particle size distribution.
Silicon carbide is an exceedingly hard, synthetically produced crystalline compound of silicon and carbon. It is a vital material for the abrasive, metallurgical, and refractories industries, where it is used in sandpaper, grinding wheels, cutting tools, and wear-resistant materials. It is also used to make specialized power semiconductor devices for high-voltage applications, such as electric vehicles and 5G infrastructure.
SiC can be made using two different methods: reaction bonding or sintering. Each forming method significantly impacts the microstructure of the final SiC product.
Miller and Company offers a variety of briquettes designed to add silicon and carbon to iron melted in cupola furnaces. These briquettes help reduce foundry coke consumption and can result in significant cost savings. Contact our experienced team to learn more about the many uses for our metallurgical briquettes.
