Currently, many units of world steel output is only the level of the 1990s, the efficiency is low in production, the variety is limited, advances in technology and technological innovation is of course not compete with the international pace. With the steel industry is facing the modernization of equipment, in addition to coping with the demands of energy conservation, quality control problems in China's steel industry. Another technique in the series, their R & D and technology imports weakened the capacity is not sufficient laboratory research and development products for too long, etc., the capacity expansion of steel.
A wide range of applications, steel
Steel can be classified according to the use of structural steel, bearing steel tool steel, die steel, spring steel, cold heading are steel, special alloys. Steel construction for all types of machinery transmission parts, screws, parts and machinery for the manufacture of ball bearings and steel structure with a fixed die steel used to manufacture different types of tools cutting, cutting tools, measuring tools and molds. Steel for quality and performance requirements are very strict, so that the products are widely used in aerospace, nuclear, military products and other special areas.
Automobiles, machinery is an important steel industry downstream, which represented about 35% of the accounts of automotive equipment for about 24%, the steel industry, the two most important needs of the market. The automotive industry is the largest steel steel applications accounted for over 60%. The engineering industry is represented by the traditional manufacturing industry, a major national industry base, steel consumption is important, but in the past is an important factor in promoting the development of special steel. Currently, many large reaches of China to world-class engineering whole plant, but the key to support the restrictions common parts will result regardless of the constituent materials of the service development of the steel industry from building .
