V. Successful Cases, Witnessing Strength
Solet's customer cases are spread all over the country, including many successful electric furnace improvement projects. Through professional inspection and diagnosis, the electric furnace improved by the company for a certain company not only solved the problems of heating element damage and high energy consumption, but also achieved an energy-saving effect of about 20%, significantly improving the quality of calcined products.
Customer Case:
Improvement of old electric furnace, achieving good energy-saving effect
A company purchased a high-temperature electric furnace with an effective volume of 4m³ for calcining alumina products, and its calcining temperature is 1650℃. The main problems of the electric furnace during use are: 1) The heating elements are severely damaged, and the heating elements are almost broken in each furnace. 2) Excessive energy consumption leads to high sintering costs. 3) The furnace lining is severely damaged, and almost every furnace needs maintenance. 4) The temperature difference is too large, resulting in large fluctuations in the quality of calcined products. The existence of these problems makes this electric furnace almost unable to be put into normal use, requiring our company to carry out improvement.
Our company conducted a detailed inspection and diagnosis of the electric furnace. The main reasons for the failure of the electric furnace to work normally are: 1) Insufficient design power leads to overloaded operation of the heating elements. The consequences of overloaded operation are not only that the heating elements are easily damaged, but also that the surface temperature of the heating elements is too high, which easily causes the furnace lining temperature to be too high and damaged, and also easily makes the temperature of the products close to the heating elements too high, leading to inconsistent sintering degree of the products and quality fluctuations. 2) The heat storage capacity of the furnace lining is too large and the thermal insulation performance is too poor, resulting in excessive heat loss and increased energy consumption. 3) There is a problem in the circuit design of the control system, resulting in excessive reactive power consumption. Excessive reactive power consumption not only greatly increases power consumption, but also has a certain impact on transformers or power grids, and is often punished by power management departments.
In response to the above diagnosis results, our company refitted the electric furnace. The measures taken are as follows: 1) Increased the number of heating elements to increase the service power, ensuring that the heating elements do not operate overloaded. 2) Adopted the composite furnace lining structure designed and produced by our company. It can not only reduce the heat storage capacity of the furnace lining by about 20~30%, but also reduce the actual service power of the electric furnace by about 20%. 3) Adopted the intelligent control system designed and manufactured by our company. This control system can ensure that the operating voltage of the electric furnace is always maintained at 220V or 380V, eliminating the impact of reactive power consumption.
The improved electric furnace has been in use for more than half a year. The use results are: 1) The electric furnace has strong operational reliability, and no phenomena such as heating element damage or furnace lining damage have occurred, meeting the requirements of normal production. 2) The furnace temperature difference is small, which greatly improves the quality of calcined products. 3) The energy-saving effect is very obvious. Originally, the power consumption for calcining one furnace of products was about 5700~5800 kWh, and now the power consumption is usually 4500~4600 kWh, saving energy by about 20%. It can be seen that the improvement of this electric furnace is a very successful example.
With the improvement of environmental protection requirements and the continuous rise of natural gas prices, the demand for large industrial electric furnaces has increased sharply. However, as a key equipment for high-temperature products, the use requirements of industrial electric furnaces are mainly as follows: 1) Temperature requirements: ability to reach the service temperature, temperature control accuracy, furnace temperature difference, etc. 2) Operation requirements: simple operation and high intelligence. 3) Reliability requirements: ensure that various components of the electric furnace such as heating elements, furnace lining and control system do not frequently fail under normal use conditions. 4) Energy consumption requirements: take various measures to reduce energy consumption. Only by realizing the low energy consumption of electric furnaces can the replacement of gas-fired kilns by industrial electric furnaces be successful.
The tunnel-type 1750℃ high-temperature electric furnace developed by our company has been put into use, with remarkable energy-saving effect
The tunnel-type 1750℃ high-temperature electric furnace designed and built by our company has been put into use in Gongyi City. The length of the tunnel-type electric furnace is 38m, and the effective size of the furnace section is: width 500mm, height 600mm. The designed total power is 450KW, and the actual service total power is 300~320KW. It is mainly used for sintering alumina hollow sphere products, and the actual service temperature is between 1680~1730℃.
The tunnel-type high-temperature electric furnace adopts many advanced energy-saving technologies of our company: 1) Composite furnace lining technology. That is, the furnace lining brick is made into an alumina hollow brick-high temperature refractory fiber composite structure. This structure can not only effectively reduce the heat storage capacity of the furnace lining, but also increase the heat insulation effect of the furnace lining. 2) Heat blocking and fire sealing technology. Fire sealing bricks are built at both ends of each section of the furnace body, making each section of the furnace body form a relatively sealed furnace chamber, which effectively reduces the diffusion of furnace chamber heat to both ends of the electric furnace. 3) Intelligent control system. The electric furnace uses PLC technology to accurately control current and voltage, enabling it to form an accurate match with the power supply system, greatly reducing reactive power consumption. 4) Efficient heat exchange system. A high-efficiency heat exchanger designed and manufactured by our company is installed in the cooling zone of the electric furnace, which introduces the high-temperature gas from the cooling zone into the drying furnace and drying room, realizing zero power consumption of the drying furnace and drying room.
Through the implementation of the above energy-saving technologies, the energy-saving effect of the tunnel-type electric furnace is very significant. In Gongyi area, the actual cost of sintering 1 ton of alumina hollow sphere products using a gas-fired kiln is about 1800 yuan (excluding drying cost and desulfurization and denitrification cost), while the actual sintering cost using this tunnel-type electric furnace is about 1300 yuan. It can be seen that the energy-saving effect of this tunnel-type electric furnace is very significant. This electric heating tunnel kiln fills a gap in China's high-temperature industry, and many of its technical indicators are at an advanced level in China.
Example of Comparison of Energy Consumption and Calcination Cost between Gas-Fired Kiln and High-Temperature Electric Furnace
A listed company uses a gas-fired kiln to calcine steel ladle permeable brick cores. The volume of the gas-fired kiln is 7m³, the actual kiln loading capacity is about 5 tons, the calcination temperature is 1580~1600℃, and the actual calcination time for each kiln is about 140 hours (heating up + heat preservation). Each kiln consumes about 1500m³ of natural gas. The power consumption of the two fans (auxiliary exhaust fan and smoke exhaust fan) is about 3800 kWh. The actual consumption cost for calcining one furnace is about: natural gas 1500m³ × 3.9 yuan/m³ = 5850 yuan; power consumption 3800 kWh × 0.9 yuan/kWh = 3420 yuan. The total is 9650 yuan. The sintering cost per ton of products is about 1930 yuan.
The company ordered a high-temperature electric furnace produced by our company with an effective volume of 4m³, a calcination temperature of 1580~1600℃, and an actual loading capacity of about 5 tons. The designed power of the electric furnace is 300KW, the average service power is about 200KW, the calcination time for each furnace is about 40 hours, and the actual power consumption is about 200KW × 40 hours = 8000 kWh. The electricity fee is about 8000 kWh × 0.9 yuan/kWh = 7200 yuan. The actual sintering cost per ton of products is 1440 yuan.
Compared with gas-fired kilns, high-temperature electric furnaces have the following advantages:
Simple operation and high degree of automation. The electric furnace can automatically heat up, keep warm and cool down according to the sintering requirements of the calcined products.
Large loading capacity. The kiln loading capacity of electric furnaces is usually 1.6~1.8 times that of gas-fired kilns.
Short calcination cycle. Since the heating and cooling of electric furnaces are faster than those of gas-fired kilns, the calcination cycle can usually be shortened by half compared with gas-fired kilns.
Stable calcination quality of products. The electric furnace can completely heat up, keep warm and cool down according to the sintering temperature curve of the products, and each furnace of sintered products can achieve a good sintering degree.
Save labor costs. Usually, only one person is needed on duty during the operation of the electric furnace, and the calcination cycle is short, which can greatly save labor costs.
Save environmental protection costs. The use of electric furnaces does not require desulfurization and denitrification devices. Even if corresponding treatment measures need to be taken for harmful gases generated during the calcination process, the operating cost is much lower than that of desulfurization and denitrification.
