Both blast furnace coke and foundry coke are made by baking a blend of selected coking coals in certain high temperature without contact with air until almost all of the volatile matter is driven off. The resulting product, coke, consists principally of carbon, as listed in above table. By-products are crude coal tar, light oils, and ammonia, etc.
Generally speaking, chemistry, size, and strength have been considered the most important properties for use in the blast furnace. Other important factors are coke reactivity and csr (coke strength after reactivity), which deal with the amount and size of pores and walls, porosity, and density. Carbon textures and microstructure are two main factors that affect the reactivity, stability, and the coke strength after reaction.
Met / foundry coke uses:
Widely used as a fuel by foundries in cupolas for melting iron scrap and pig iron.
·in sugar mills employing the carbonizing process.
·for making chemicals/calcium carbide.
·used in the pharmaceutical industries.
·coke breeze is used for steam generation in boiler houses.
·used in steel making for carbon adjustment.
Semi-coke can replace coke (metallurgical coke) and is widely used in chemical industry, smelting, gas production and other industries. It is superior to coke in the production of high energy-consuming products such as silicon metal, ferroalloy, ferrosilicon, silico manganese, fertilizer and calcium carbide.

Semi coke is made from high grade Jurassic coal as a new type of carbon material. Semi coke produced in China, and main production city in Shaanxi China. Semi coke can instead of metallurgical coke to be used in producing ferroalloys products. Semi-coke is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus. It is wildly applied to chemical industry, metallurgic industry, and gas- making industry to produce Ferroalloys, ferrosilicon, Ferronickel ,Ferrochrome, FeMn & SiMn, as well as Calcium carbide and, fertilizer, etc.

Semi coke is made from high grade Jurassic coal and as a new type of carbon material. It can be instead of some metallurgical coke when produce ferroalloys products.
Using semi coke during steel making, blended the semi coke with met coke, which reduced their cost 20% to 30% than using met coke only.
Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer
(1). Semi Coke could improve the quality of the ferro alloy significantly (especially low aluminum alloy Al2O3�¢?�¤0.1%).
(2). Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%)
(3). Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but its far cheaper than charcoal and pet-coke
(4). Its very simple to replace coke, pet-coke and charcoal with semi coke. Its no need to upgrade your equipment and the operation is easy and process is simple.
Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron.
It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.
Semi coke can be 100% used in the production of ferrosilicon and ferronickel, reducing production power consumption and increasing single furnace output.

Foundry coke is widely used in iron making because of its special physical and chemical characteristics. It's the main cupola molten iron fuel, foundry coke plays an important role in melting furnace charge and overheat the molten iron, support stock column, maintain good
air permeability. Therefore, foundry coke with large size,low reactivity, low porosity, sufficient impact resistance and crushing strength, low ash and sulfur content, it is popular in the international markets.
