The electrode paste consumption of the calcium carbide industry accounts for about 70% -80% of the total output of electrode paste. The calcium carbide market continues to improve and is also a development opportunity for the electrode paste industry.

electrode paste is a conductive material for electric furnace equipment such as iron alloy furnace and calcium carbide furnace. It can withstand high temperatures and has a small thermal expansion coefficient. With a relatively small resistivity, it can reduce the loss of electrical energy. With a smaller porosity, the electrode in the heated state can be oxidized slowly. With higher mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads.

Benefiting from the renewal of the calcium carbide industry in China, the calcium carbide industry has ushered in a great development, and it has also made a rapid development in China's electrode paste market after 2015. But since 2016, the industry has started to enter the downward channel.

Relevant data shows that the electrode paste industry consumes about 70% -80% of the total output of electrode paste, and the calcium carbide market continues to improve, which is also the development opportunity of the electrode paste industry. Due to the integration of coal enterprises and the improvement of mining efficiency, the yield of raw lump coal for the production of blue charcoal has continued to decline, and the price has risen, which will continue to increase the raw material costs of calcium carbide enterprises. In addition, for the sake of energy saving, emission reduction and environmental protection, the cleaning and rectification efforts of lime kilns are constantly increasing, resulting in a tight supply of raw white lime for the production of calcium carbide and rising prices, which will also increase the production costs of calcium carbide enterprises. In this context, electrode paste is also facing pressure to increase prices.


In the face of a sluggish industry environment, relevant companies should seek a way out. First of all, the index of electrode paste should be changed. The purpose of electrode paste is to make conductive material, and the index of conductive material should be focused on specific resistance. Secondly, changes should be made in raw materials. The raw materials used in the production of electrode paste are basically ordinary calcined anthracite, metallurgical coke powder, and medium-temperature coal pitch; it should be updated to use electric calcined anthracite, calcined petroleum coke, and modified coal pitch. In addition, the current overall equipment of the electrode paste industry is not enough. It must be fully supported from crushing, screening, grinding, batching, mixing, kneading and molding.

The calcium carbide industry is developing towards large capacity and large-scale, and the electrode paste industry must also adapt to the market and develop toward large-scale. Relevant enterprises should comply with the development requirements of the times, promote the improvement of electrode paste quality, and get out of the downturn as soon as possible.
