Editor's Note: China is a large country of corundum abrasive production. There are more than 200 Gangwang smelting enterprises and nearly 400 corundum smelting furnaces in the country, with an annual production capacity of more than 3 million tons and an actual annual output of more than 2 million tons. If the smelting corundum is calculated at 2300 kWh per ton, the annual electricity consumption will be about 4.6 billion kWh. The corundum smelting energy-saving control cabinet, after careful comparison test, has a good power-saving effect and is worth promoting. For example, China's corundum smelting all use power-saving control cabinets, calculated according to 120 degrees per ton of corundum power saving, the annual power saving 240 million degrees. Its economic and environmental benefits are considerable. It is suggested that China's corundum smelting enterprises may wish to give it a try.
The power-saving control cabinet for corundum smelting is a brand-new thing. The brand-new product is the energy-saving equipment that is urgently needed for corundum smelting. After a serious scientific comparison test in Zhengzhou Jinhao Abrasive Co., Ltd. for 4 months, the power saving effect is very obvious. It is used to smelt white corundum. The electricity consumption per ton of aluminum oxide powder drops by 144.6 degrees on average, and the average power saving is 7.42%. Schedule I). For the sake of prudence, we have also tested the power consumption of the white corundum block on the 1350KVA shelling furnace and the 2000KVA dumping furnace. The result is 168 degrees and 368 degrees per ton of primary block (see Table 2). Table 3). However, there are still many difficulties in the promotion and use of such energy-saving products. As the smelting enterprises have little understanding of the corundum energy-saving control cabinets, they cannot be accepted very quickly. Although the current corundum products of the corundum smelting enterprises are high, However, everyone does not feel that their power consumption is high, and they do not feel that they have lost about 8% of smelting electricity. Because there is no comparison, they can't find the gap and can't see the loss. Under the premise that enterprises can still make profits, there is no incentive to save energy and reduce consumption. Some enterprises have been smelting for several decades or even decades, knowing that energy conservation and consumption are difficult, and even that they are in the process of smelting. Saving electricity is impossible, so I don't want to invest in this area, because before the energy-saving control cabinet, the company can't see the hope of energy saving, and there is no idea of ​​energy saving.
According to the actual situation encountered in the process of promoting energy-saving control cabinets, Shanghai Hi-Tech Power Installation Co., Ltd. decided to focus on the energy-saving technology effect display of corundum energy-saving control cabinets with the focus on the most concentrated production area of ​​white corundum. The energy-saving effect is displayed to the corundum smelting enterprise, allowing the enterprise to see the high-tech energy-saving products of corundum smelting---the corundum smelting energy-saving control cabinet, seeing its energy-saving effect and bringing direct economic benefits. During the event, the company plans to install all the corundum enterprises in the Xiangyang area free of charge before the end of December 2009, free trial, each company for one week.
We are willing to work together with all the corundum smelting enterprises to implement the relevant policies of national energy conservation and emission reduction, save energy, and benefit future generations, so that our days are bluer, mountains are greener, water is clearer, and our society is more harmonious.
