Making chips is a complex process requiring hundreds of precisely controlled steps that result in patterned layers of various materials built one on top of another. A photolithographic "printing" process is used to form a chip's multilayered transistors and interconnects (electrical circuits) on a wafer.

The main division is between "coking" coal and "energy or steaming" coal. Coking coals, used to make coke for use in blast furnaces, have particular properties which allow it to form a good coke when put through a coking process which involves heating in an atmosphere deficient in oxygen.

COKE PRODUCTION FOR BLAST FURNACE IRONMAKING

The third series of coking tests was carried out using blends B20, B30 and B40 (semi-soft coal content respectively: 20, 30 and 40%) with 30% flotation concentrates content and optimal share of the briquettes. Two coking tests were performed for each of the blends: the first test included

How is Steel Produced? | World Coal Association

Coking coals within the rank range 1.15 – 1.4% reflectance are considered prime coking coals if the ash content is < 9.5% and sulphur approximates 0.6%. Coal such as this is the most expensive and coke manufacturers try and reduce costs by using coals classed as soft coking (make a weaker coke) and semi-soft coking (are weakly coking) coals.

Coking Coal Processing Content Of Magnetite

A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.. Delayed coking is one of the unit processes used in many oil refineries.The adjacent photograph depicts a ...

Analysis: Australian thermal coal producers eye coal ...

Thirdly, when producing semi-soft coking coal from a wash plant, some coal volume is lost in the process -- up to 10% -- and this can impact profit margins, a source said. Australian coal producers incur a cost of about $3/mt from washing thermal coal which has the effect of reducing its ash content from 14% to around 9% or less, he added.

What is Coking Coal

cokemaking process can be broken down into two categories: a) By-product Cokemaking and b) Non-Recovery/Heat Recovery Cokemaking. A brief description of each coking process is presented here. The majority of coke produced in the United States comes from wet-charge, by-product coke oven batteries (Figure 1).

This is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used, as well as the coke plant operating conditions. Coke quality is largely influenced by coal rank, composition, mineral content and the ability to soften when heated, become plastic, and resolidify into a coherent mass.
