Influencing factors and reduction measures of electrode paste consumption in mine heating furnace
The consumption of electrode paste in mineral heat furnaces is affected by a variety of factors, including furnace type and furnace condition, raw material quality, operating level, and electrode paste quality.In order to reduce the consumption of electrode paste, a series of targeted measures can be taken.The following is a detailed analysis of these influencing factors and reduction measures：
1. Influencing factors
Furnace type and condition：
The furnace type design directly affects the consumption of electrode paste.
Good furnace conditions, such as stable furnace temperature and suitable atmosphere in the furnace, help reduce the consumption of electrode paste.
Raw material quality：
The impurity content, moisture, particle size distribution, etc. of raw materials will affect the consumption of electrode paste.
Poor-quality raw materials may lead to the need for more electrode paste in the production process to maintain a stable reaction.
Operating level：
The skill level and operating habits of the operator have a significant impact on the consumption of electrode paste.
Skilled operators can control the production process more accurately and reduce unnecessary waste.
Electrode paste quality：
The conductivity, high temperature resistance, compressive strength and other characteristics of the electrode paste directly affect its consumption rate.
High-quality electrode pastes have better performance and can maintain stability for a longer time in the production process.
2. Reduction measures
Optimize the production process：
Improve the production process, improve the energy conversion efficiency, and reduce unnecessary energy loss.
Reasonably adjust the proportion of ingredients to ensure that the quality of raw materials meets the requirements.
Selection of high-quality raw materials and electrode paste：
Choose raw materials with high carbon content, low ash content, low moisture content, and low volatile content.
High-quality electrode paste is selected to ensure that it has good electrical conductivity, high temperature resistance and compressive strength.
Strengthen electrode management：
Strictly control the working length and furnace depth of the electrode to ensure that it is within the range of process requirements.
Stop the furnace regularly to check the use of the electrodes, and replace the severely worn electrodes in time.
Improve the level of operation：
Regularly conduct skill training for operators to improve their operating level and energy-saving awareness.
Establish a sound operating procedures and assessment system to ensure that operators can operate in strict accordance with the procedures.
Improved electrode paste formula：
By improving the formula of the electrode paste, its quality and performance are improved.
Add suitable additives, such as residues of suitable particle size, carbon rods, etc., to improve the compressive strength and bulk density of the electrode paste.
Strengthen equipment maintenance：
Regularly maintain and overhaul the mine heating furnace and its ancillary equipment to ensure that it is in good working condition.
Deal with equipment failures and hidden dangers in a timely manner to prevent the increase in electrode paste consumption caused by equipment problems.
Reducing the consumption of electrode paste in mine heating furnaces needs to start from many aspects, including optimizing production processes, selecting high-quality raw materials and electrode pastes, strengthening electrode management, improving operation levels, improving electrode paste formulas, and strengthening equipment maintenance.The implementation of these measures will help reduce production costs, improve production efficiency and product quality.
