Including capital steel company, Tianjin steel mills and Tangshan Iron and Steel Company, it is one of the important steel bases in the country. The output of major steel products accounts for about 10% of the national total output. Among them, the output of finished steel accounts for 13% of the total national steel production. The favorable conditions of the Beijing-Tianjin-Tangshan Iron and Steel Base are: 1There are abundant resources around the base. The Jidong Iron Ore Base has large iron ore mines such as Qian'an and Qixian. The reserves are second only to Saddle-Ben; there are large coal fields such as Kailuan and Jingxi. Kailuan Coal Mine has an annual output of more than 20 million tons. It is the largest high-quality coking coal base in China. 2 The base has superior location and developed transportation. The only way to contact inside and outside Shaoguan is railways and highways. There are important seaports such as Tianjin and Qinhuangdao. 3 The base is close to the consumption area and has strong technical strength. Beijing is China's political and cultural center. Tianjin is the largest port city in the north and the economic center of North China. Tangshan is an important industrial city in Hebei Province. The three cities rely on each other and are closely linked. They have become one of the important economic regions in the north of China and a major consumer of the steel industry. From the perspective of the whole base, the selection, smelting and rolling capacity are generally balanced. Shougang is the largest steel conglomerate in Beijing, Tianjin and Tangshan. After nearly ten years of reconstruction and expansion, it has formed a production capacity of 3 million tons. It has changed the production of pig iron in the past, which is greater than the steel output. The steel output is greater than the imbalance of steel. In 1990, it produced 3.57 million tons of iron, 4.35 million tons of steel, and 3.74 million tons of finished steel. Shougang has advanced technology and all economic indicators have maintained domestic advanced levels. The steel mills in Tianjin are mainly steel-making and steel-rolling. The iron-making base is located in the south of Hebei Province, and is more than 500 kilometers away from Tianjin. Every year, it is necessary to transfer nearly one million tons of pig iron from the field for iron and steel making; and transfer a large number of billets for rolling stock, causing unreasonable conditions such as round-trip transportation and energy waste. Tianjin's steel products are diverse, mainly small and medium-sized steel and metal products. Similar to Tianjin, Tangshan Iron and Steel Co., Ltd. established steelmaking bases in Xuanhua, Hebei. During the “Seventh Five-Year Plan†period, Tangshan Steel added 750,000 tons of pig iron production capacity, 1.72 million tons of raw ore processing capacity, 850,000 tons of continuous casting capacity and 350,000 tons of rolled material capacity. The continuous casting production capacity was 50,000 tons at the end of the “6th Five-Year Plan†period. , increased to 900,000 tons, the continuous casting ratio also increased from 4.21% to 43.96%. Metallurgical Machinery Bearings Bearings play an important role in the metallurgical industry, mainly in the following aspects: Metallurgical Machinery Bearings,Equipment Metallurgical Bearings,Bearings For Metallurgical Machinery,Equipment Metallurgical Bearing Hebei Fangqiang bearing manufacturing Co., LTD , https://www.fangqiangbearing.com
1. Equipment operation: The metallurgical industry uses a large number of rotating equipment, such as rolling mills, ovens, cooling equipment, etc., and the normal operation of these equipment is inseparable from the support and guarantee of bearings. Bearings can reduce the friction and wear of equipment, improve the reliability and operation efficiency of equipment.
2. Load bearing: The equipment in the metallurgical industry usually needs to bear heavy loads, and the bearings can bear and distribute these loads to ensure the stable operation of the equipment. For example, in the rolling process, bearings are subjected to high temperatures, high speeds and large loads, which can ensure the normal operation of the rolling mill.
3. Temperature and environmental adaptability: The working environment of the metallurgical industry is usually harsh, such as high temperature, high humidity, corrosive gas, etc., and the bearing needs to have good high temperature resistance, corrosion resistance and other characteristics to adapt to these harsh environments.
4. Energy saving and emission reduction: The optimal design and selection of bearings can reduce energy consumption and emissions, and improve the energy utilization rate of equipment. For example, the use of low-friction bearings and high-efficiency sealing structures can reduce energy consumption and lubricant consumption.
To sum up, bearings in the metallurgical industry not only ensure the normal operation of equipment, but also improve the reliability, stability and energy efficiency of equipment, and play an important supporting role in the development of the metallurgical industry
