Coke's role in steelmaking is to provide the heat needed to melt the ore, whose natural state is iron oxide, the rust you see on iron after it has been exposed to the atmosphere. Coke also 'steals' the oxygen from the iron ore, so that it can become iron. In the coking plant, coal is heated to 1250c in the absence of oxygen, removing impurities and …
Abstract The coal blends are used for both top and stamped charged coke oven batteries in Steel Plants which are consists of more than 5 to 7 individual coal sources depending upon the availability of coking coal. The blast furnace (BF) coke produced from the coke oven batteries are feed into both small and larger BF. The …

Ans. A coke oven plant is a facility where coal carbonization takes place. It consists of a series of ovens where coal is heated in a controlled manner to produce coke. The purpose of a coke oven plant is to convert coal into coke, which is a vital raw material for iron and steel production.
A coke oven is a device used to produce coke, a product that is derived from coal. The mixing and heating of bituminous coal at temperatures ranging from around 1832° to 3632°F (1000° to 2,000°C) within the airless oven yields the coke byproduct. This device is a crucial part of the coke-making process.
In this study, the energy view of an oven of a 70-oven coke battery in an iron and steel plant was evaluated based on operating parameters and recommendations for …

In the 17-day test, the grain size of high-coking pressure coal A was changed from −3 mm 82% to −3 mm 96% step by step. The working rate of the coke oven was 121% dur-
Ten batteries, each holding 60– 90 coke ovens, bake around the clock at the 390-acre plant to make about 4.3 million tons of coke a year. The shuttered Shenango coke works on the Ohio River, by comparison, operated only one 56-oven battery to produce 350,000 tons of coke.

Vertical coke ovens are universal units for the pyrolysis of a diverse range of different feedstocks. Even low-grade feedstocks such as bituminous coal, lean coal, gas coal, flame coal, lignite, anthracite or biomass can be used. However, while low-grade coal is easy to mine, it is difficult to convert into coke.

Some coke plant accidents have been deadly. Online OSHA records show that in 2006, a worker at an AK Steel Corp. plant was crushed between two machines and killed. In May 2001, two workers at a Bethlethem Steel Corp. plant were killed as they were removing a shut-off valve from a coke oven gas line.
The double toothed roll crushers are one of the most economical and practical medium and fine crushers. They are very popular among small coal processing plants. The double toothed roll crusher is suitable for crushing medium-hard coal with high moisture content (more than 25%), such as raw coal, coke, lignite, and activated carbon.
To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
