Calcined anthracite (injectable):

Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.

Anti-wear anthracite

As many steel companies tended to use crude anthracite instead of calcined anthracite, after consumption, they realized that the amount of crude anthracite wear for equipment is higher than oil coke and metallurgy.

Now, due to technical knowledge and research in this aspect, Petrosaman Company has started to produce anti-wear anthracite coal.

This product no longer damages industrial devices and equipment due to its anti-wear properties, and it is also not necessary to spend a lot of money to maintain, repair or replace abrasive surfaces.

This can be a vision for the relevant industries so that by consuming this product, they no longer have to worry about the degradability of the equipment and avoid spending a lot of money.

Coal and Concentrate (PCI)

Thermal coal is one of the types of coal and a sub-branch of bituminous coal, which according to its properties and characteristics, it can be used in certain cases.

Thermal coal is divided into two categories, low calorific value coal (LOW CTE) and high calorific value coal (HIGH CTE). The reason for this difference is related to the stages of coal transformation in the earth.

This coal has a lower coking property than coking coal, so it has a more reasonable price.

Basically, the sulfur content of hot coals is less than that of coking coals. It is worth mentioning that sulfur absorbs heat in the form of sulfate when it burns and combines up to 2% of its weight with oxygen and 4% of its weight with water.

Graphite electrode

According to international standards, graphite electrodes must be made from calcined petroleum coke (CPC). Needle coke production technology, as the main raw material of CPC, is available exclusively to countries such as China, USA, Japan and Germany. This has made the manufacture of graphite electrodes as the main consumable material in electric arc melting furnaces, the monopoly of developed countries.

To produce graphite electrodes, needle coke powder is first molded and compressed with a vibrator. The formed electrode is then baked in an oven. After baking, a layer of bitumen is added to it. Finally, this product is again at a temperature of 3000 degrees Celsius and turns into graphite.

After the production process, turning operations are performed on the electrodes. These electrodes are mostly produced in a cylindrical shape and after production must be cut in standard diameters. It is necessary to install a pin as a socket on the electrode head.
