1. The industry has a long way to go for energy saving and emission reduction. Abrasives as a relatively special industry, there are problems in energy-saving emission reduction abrasive smelting. At present, there is overcapacity in the domestic brown corundum situation. The next step in the national policy will be to eliminate the backward production capacity of the corundum industry, shut down some high energy-consuming medium and small corundum production enterprises, eliminate low-power smelting furnaces, and encourage advantageous companies to become stronger. Bigger.
2, excess capacity. The production of corundum is particularly prominent. Overcapacity and homogenization of low-end products will become increasingly unacceptable to the market. Especially after entering July, the situation is even more severe. The south five provinces continue to suffer droughts, especially in Guizhou, and electric power is severe in July. Insufficient, all smelting enterprises stopped production.
3, new product research and development capabilities are weak. At present, China has become a major producer of abrasives, but it is not yet a powerful nation. Abrasive products in China are mainly concentrated in the low-end market, and have low technological content. Compared with the international advanced level, there are still large gaps. The lack of domestic high-end technology products mainly depends on imports. The gap between high-end product performance and foreign product ratio is large, and it can only meet 30% of the demand for several pillar industries of automobiles, aerospace, machine tools, bearings, locomotives, and ships; the majority of product exports maintain the traditional middle and low grade, and the average export price. Only 1/10 of the average price of imported products.
4. The production capacity of abrasive grinding tools has become a scale, but the specific production capacity is relatively decentralized, the scale of the company is small, and the scale efficiency is poor. The scale structure of the company is still not reasonable, the industrial concentration is low, and small enterprises still account for a large proportion. The low competitiveness of enterprises and products has seriously affected the improvement of the economic strength of enterprises, in particular, it is not conducive to environmental protection and technological upgrading.
