Cokes

Cokes Coke is a synthetic raw material used for producing carbon in combination with binding agents (or binders). There are different kinds of coke, e.g. petroleum coke, pitch coke, metallurgical coke, carbon black, needle coke. For a summary of their characteristic.

This work investigated several methods for improving the wear resistance of the 42CrMo4 tool steel used for coke-crushing hammers. The methods embraced heat treatment for obtaining different combinations of strength and ductility of the bulk steel, and surface-engineering processes comprising TiN thin-film deposition using magnetron-sputtering, nitriding and WC/Ni weld deposit surfaced by gas.

Low Ash Metallurgical Coke CSR62% real

The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10.

Metallurgical properties of brex

 · Brex made from metallurgical slags, iron-ore concentrate, manganese ore, screenings of metallized pellets and ferroalloys, coke fines, and coal were studied to evaluate their mechanical strength and hot strength and determine their behavior during heating in a reducing atmosphere. The metallurgical properties of brex make it possible to successfully use them in steelmaking and various.

Coal and Coke Analysis

 · The student need not, unless he have ample time, proceed with a detailed analysis of coke. A good coke should be low in ash, sulphur, and phosphorus, and high in fixed carbon. It also should be up to a certain physical standard as regards crushing resistance, porosity, specific gravity, etc. (consult Coke: its Manufacture and Recovery of Bye-Products, by John Fulton).

Metallurgical Coke

 · It takes around 12 hours to 15 hours for the centre of the coke oven to solidify. The semi-coke shrinks and fissures at elevated temperatures of 500 deg C to deg C losing methane and hydrogen. The coke is pushed out of the coke oven at around deg C to deg C, when the volatile matter is less than 1 %.

 · Available methods of assessing the characteristics of coke—in particular, its strength—are reviewed. Their relative advantages and disadvantages are considered. A method of direct determination of coke strength is proposed, including a method of assessing the crack resistance in which the porosity and also the shape and size of the sample are taken into account.
