As the global demand for alloys such as steel increases, so does the market. This is due to a variety of factors such as the growing demand for sustainable industrial practices and energy-efficient processes. In addition, the demand has been fueled by environmental concerns and the drive to improve energy efficiency.
Electrode paste for metal smelting is composed of a combination of powdery materials. There is a mixture of powdery carbonaceous materials, including calcined coal anthracite and coke. A binding substance or binder is also used. It is the coal tar that facilitates the cohesiveness and adhesion between the carbon particles of the electrode paste. This prevents their disintegration when the electrodes are used.
The electrode is put under stress by the different thermal behaviours that the anthracite calcined filler has compared to the coal-tar pitch binder. First time this risk has scientifically been explained using a novel thermomechanical technique which focuses on changes in the electrode's shape.
This study investigated the effect of three different types of anthracite calcined and two coal tar pitchs on the stability of electrode paste during transformation in the submerged-arc furnace. The results revealed that the calcination of the anthracite plays a critical role in the development of stable electrodes. The calcination affects carbon particle sizes and the dimension stability of the paste.
One of the most important factors in determining how stable the electrode will be is the rate with which coal tar pitch shrinks while baking. The researchers found that, as the temperature of calcination increased, so did the size changes. They recommend that future production of electrode pastes use a higher calcination experiment temperature to assure dimensional stability.
Other: This category covers a range of special electrode paste formulations, which differ from those in the classifications for standard and obturation. The innovative formulations meet niche operational requirements while contributing to the overall growth of electrode paste.
Electrode paste has a wide range of applications, including the manufacture ferroalloy. Due to the fact that the paste is able to reduce the oxides in the process of melting. The paste is a key step in the melting process. This results in a higher-quality product that can be applied in industrial and construction applications. Calcium carbide production, metal cleaning and the manufacturing of phosphorus are also other applications. The 'others' category also includes emerging markets, where the unique properties of the electrode paste are being utilized for diverse industrial purposes. Obturation, also called the sealed type or the type with a seal, is preferred by industries that are concerned about contamination.
