Brown corundum smelting furnace energy saving report

Chen Hong, the general manager of Zhengzhou Guangzhi Complete Machinery Equipment Co., Ltd. In today's world, in the process of industrialization, energy conservation and emission reduction is not only the trend of national policies, but also the need to reduce costs and promote a low-carbon economy. It is about energy and environmental protection, and will always be valued and pursued by human beings.
Any enterprise, any product, no matter what high, large, fine, and pointed products, how high the scientific and technological content is, or ordinary ordinary low-grade products of the pots and pans commonly used by the people, the production enterprises will be carefully designed and reasonable under the premise of ensuring the quality. Produce, reduce costs, and strive to maximize economic benefits.
Here, I mainly talk about some of the understanding and experience accumulated in the production of brown fused alumina smelting furnace. As a manufacturer of this product for many years, through continuous learning, research and development, exploration, improvement, and practice, we gradually deepen our understanding from the initial general understanding, step by step, to achieve such an ideal level.
The brown fused alumina smelting furnace consumes a large amount of electricity during the production process and is a veritable electric tiger. How to reduce power consumption, this is our main direction. In this regard, we have continued to practice and proceed from the following three aspects:
First, shorten the conductive distance As we all know, the lower the voltage, the longer the wire, the greater the resistance, the higher the consumption, the higher the wire loss of the wire. After continuous exploration, we have improved the length of the wire. The conventional furnace has a wall of 0.8 m, a middle copper tube of 5.8 m, a soft copper strip of 3.2 m and a total length of 9.6 m. After the improved handle, the wire was shaped to 5.5 meters and shortened by 4.1 meters.
Second, reduce the conductive contacts According to the data: 5000KVA transformers consume 10 degrees of electricity per hour, each transformer is calculated according to 12 joints, the power consumption is 120 degrees per hour, we start from reducing the joints, first, change the conventional joints From the transformer, take the wall copper plate, then connect the conductive copper tube, then connect the soft copper strip, and finally connect the handle, at least 4 interfaces. After we improved, we only used 2 joints to jump directly from the transformer to the handle, reducing 24 joints, thus reducing the power consumption of the joint.
Third, cooling and power saving Conductive resistance is proportional to the temperature, according to the theory, the resistance difference is 0.004 for each high degree of one degree, the copper discharge temperature is 120~180 °C, the water temperature is 50 degrees, and the difference is 70 degrees.
In this way: reduce the joint, according to the 5000KVA transformer, 12 joints consume 120 degrees, 20 hours per day, 120 × 20 hours = 2400 degrees. Shorten the conductive distance: According to the calculation of 4 meters, each cable saves 100 degrees / hour, according to 20 hours per day, can save 2000 degrees per day. Cooling of the catheter: The temperature of the catheter is 70 degrees × 004 = 0.28, which is equal to 2680 degrees according to 9600mm2.
These three items reduce the joint by 2400 degrees + shorten the conductive distance by 2000 degrees + cool down 2680 degrees = 7080 degrees, calculated by 5000 degrees per day, which is 150,000 degrees per month.
In the past, the country imposed a price hike on our smelting industry, which was 0.3 yuan per kWh. Now it is adjusted to 0.7 yuan. It is more than enough. The pressure of the enterprise can be imagined. According to the smelting furnace produced by our company, the daily power saving is 5000 °C× 0.7 yuan = 3,500 yuan.
In short, energy conservation is related to the development and life of enterprises. Through continuous reform and innovation, increasing the competitiveness and vitality of enterprises and creating good economic and social benefits are the pursuit of enterprises.
