Coke metallurgy, a comprehensive introduction to coke

What is metallurgical coke and its chemical elements and weight density

Metallurgical coke is a type of fuel used in metallurgical industries to process metals. Metallurgical coke is used as an energy source and also as a carbon material. In various metallurgical processes, minerals such as iron ore, bauxite (aluminum ore) and others are converted into coke, which is then used as a fuel for thermal processes.

There are several types of coke, but coal coke and petroleum coke are the two most common types. Coal coke is made from pure coal and petroleum coke is made from heavy crude oil.

The chemical elements in coke mainly include carbon and mineral elements such as silicon, aluminum, manganese and iron. These elements are naturally present in minerals such as coal and oil.

The weight density of metallurgical coke depends on the type of coke and the content of its chemical elements. In general, the weight density of metallurgical coke is between 1.5 and 2.2 grams per cubic centimeter.

Properties and characteristics of metallurgical coke

Metallurgical coke has characteristics and properties that make it a useful fuel in metallurgical industries. Some properties and characteristics of metallurgical coke are:

1. Heat resistance: Coke has high heat resistance and can be used as fuel continuously at high temperatures. This feature makes metallurgical coke very suitable for industrial processes with high temperatures such as steel, aluminum and other metal processing.

2. Chemical resistance: coke has high chemical resistance against oxidation and water. This makes metallurgical coke work well in metallurgical processes that involve the presence of oxygen or moisture.

3. Volume stability: Coke has good volume stability, which means that it shows little shrinkage or swelling at high temperatures and in thermal processes. This feature is important because unwanted volume changes can be problematic in processes that require precision and temperature control.

4. High carbon content: Coke has a high carbon content, which is used as the main source of carbon for metallurgical processes. Carbon in coke can play an important role in metal alloying and refining processes. In alloying processes, the carbon in coke interacts with other metals and causes the desired alloys to form. Also, the carbon present in coke can be used as a tracer in metal refining processes, so that by determining the amount of carbon present in coke, the level of contamination of the purified metal can be detected.

In addition, due to the high carbon content of coke, this substance is used as a suitable fuel for thermal processes in metallurgical industries. By burning coke, heat and energy are provided for industrial processes.

Therefore, the properties and characteristics of metallurgical coke, including thermal resistance, chemical resistance, volumetric stability and high carbon content, have made it a suitable fuel material and an important factor in metallurgical processes.

Application and consumption of metallurgical coke

Metallurgical coke is used as a real and useful fuel in metallurgical industries. Some applications and places of use of metallurgical coke are:

1. Steel production: metallurgical coke is used as the main source of carbon in steel production processes. In electric arc furnaces and electric arc furnaces, metallurgical coke is used with ferrous metals to produce steel and metal alloys.

2. Aluminum production: In the aluminum production industry, metallurgical coke is used as a carbon source in the process of making aluminum from bauxite (aluminum rock). Metallurgical coke plays an essential role in the bauxite electrolysis process to produce aluminum and refine it.

3. Production of other metals: Metallurgical coke is used in metallurgical processes such as production of iron and nickel metals, steel casting, iron ore processes and other metal processing.

4. Alloy industry: Metallurgical coke is used in the production of various alloys, such as aluminum, steel and copper alloys, as a carbon source and tracer.

The place of consumption of metallurgical coke is actually related to metallurgical industries and depends on the needs and processes of each industry. Companies in steel, aluminum, copper and other metallurgical industries are usually used as the main consumers of coke in their needs of thermal fuel and carbon source for thermal processes. Depending on the type and size of the industry, this coke may be purchased ready-made from coke manufacturing companies or, in some cases, industrial companies may produce coke themselves.

Among the places where coke is used, we can mention steel plants, aluminum plants, copper plants, ferrous metal manufacturing plants and other metallurgical industries.

Metallurgical coke production process

Coke production is mainly done in metallurgical industries in the following ways:

1. Petroleum processing: One of the methods of producing coke is petroleum processing. In this method, with the process of oil oxidation and heating of crude oil in coking ovens, the carbon in the oil turns into coke. This coke production method is often used in refineries and oil processing plants.

2. Melting processing: In the melting processing method, raw materials such as coal or oil, which contain carbon, are heated in melting furnaces. In this process, the carbon in the raw materials is converted into coke using high heat.

3. Coking in special furnaces: Another way to produce coke is to use special furnaces such as coking furnaces. In this method, metallurgical coke is produced by placing alternating layers of coal and other carbon-containing materials in the furnace and applying high heat.

4. Extraction from natural solid parts: In some areas, coke can be extracted from natural solid parts such as coal. In this method, coke is produced by distillation and special processing of coal at high temperatures.

How to produce coke depends on the type and origin of raw materials, production process and intended use. Also, improving production technologies and methods can improve efficiency and reduce pollutants in coke production. For example, in the aluminum industry, more advanced methods are used, such as the aluminase process, which can produce coke with good quality and carbon content.

In general, the production of coke is done through thermal and chemical processes, which are done in order to convert materials containing carbon into metallurgical coke suitable for use in metallurgical industries.

According to the explanations given, it can be concluded that metallurgical coke is an important fuel in metallurgical industries, which is used to provide energy and carbon source in thermal processes.

Properties and characteristics of coke include high heat resistance, combustibility with air movement, adjustable carbon content and high fuel strength.

This material is used in the production of steel, aluminum, other metals and in the alloying industry.

Coke production methods include petroleum processing, smelting processing, coking in special furnaces and extraction from natural solid parts. By improving production technologies and methods, the efficiency and quality of metallurgical coke production can be increased.

Examining the applications and places of consumption shows that metallurgical industries, including steel, aluminum and copper, use it as the main consumers of metallurgical coke in their needs for thermal fuel and carbon source. Finally, further research is recommended in the field of improving production methods, reducing pollutants and optimizing the use of coke in metallurgical industries.
