Calcined Petroleum Coke

Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F). The high temperatures remove excess moisture, extract all remaining hydrocarbons and modify the crystalline structure of the coke, resulting in a denser more electrically conductive product. In a matter of hours, calcined petroleum coke is cooled from 1350 degrees C to less than 200 degrees C, when it can be safely handled and transported to storage silos or placed directly into shipping containers, trucks, railcars, barges or vessels.
Calcined petroleum coke has a sponge-like structure which plays an important role in the making of anodes. The pores allow binding material to penetrate through the coke particles and form a solid carbon block, through which aluminum smelters conduct electricity into their smelting pots. Over time, the anodes are consumed, roughly at the rate of 40 tons of calcined petroleum coke for each 100 tons of aluminum produced. Currently, there is no known commercially viable substitute for calcined petroleum coke in the fabrication and utilization of aluminum smelter anodes

Met Coke

Metallurgical coke is made from low ash, low sulfur bituminous coal, with special coking properties, which is inserted into ovens and heated to 1000F to fuse fixed carbon and inherent ash and drive off most of the volatile matter. The final product is a nearly pure carbon source with sizes ranging from basketballs (foundry coke) to a fine powder (coke breeze).Metallurgical coal is used in the production and purification of metallurgical coke. It is during the heating process that the unstable components are released. The final product is a non-melting, solid, stable carbon. However, the "ash" elements, which were part of the original bituminous coal, remain encapsulated in the resultant met coke. One attribute of met coke is its ability to burn while producing little or no smoke.

Graphite Powder

Graphite , archaically referred to as plumbago, is a crystalline allotrope of carbon, a semimetal, a native element mineral, and a form of coal. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds.

Graphite Stopper Head

These are ideal for steel molding industries and diamond refractories. They are manufactured using quality raw material as per the industry standards. With big or small knobs, these are available in several sizes and quality combinations, which can be used for variable ladle sizes of 1 metric tons to 30 metric tons of liquid steel. It is used for opening and closing of ladle that is at the nozzle of the B. P. Sets (bottom pouring sets). These heads assist in maintaining the flow of the molted steel, further preventing it from over flowing.

Work Flow Mechanism:
Graphite Stopper Head works from inside of the ladle to open and close the passage through the pouring nozzle which extends vertically through the bottom of the ladle and to control the flow of the molten metal.

Carbon Raiser

Carbon Additive/Carbon Raiser is also called “Calcined Anthracite Coal”,or “Gas Calcined Anthracite Coal”. The main raw material is unique high quality anthracite, with characteristic of low ash and low sulfur. Carbon additive has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%. Best quality Anthracite as raw materials through high temperature calcined at over 2000 degrees by the DC electric calciner which results in eliminating the moisture and volatile matter from Anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation, It has good characteristics with low ash, low resistivity, low carbon and high density. It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel. Carbon Additive may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel, for its calorific value may achieve over 9386K/KG. It may substitute burnt carbon massively. Calcined Anthracite is produced when Anthracite is calcined under the temperature of 1240 degrees in vertical shaft furnaces. Calcined Anthracite is mainly used in electric steel ovens, water filtering, rust removal in ship building and production of carbon material.
