Although the deep processing of steel in Europe is at the leading level in the world, it is still developing new equipment and products. Due to the high cost of labor force in European countries, the equipment manufacturing generally adopts the equipment with advanced technology and high degree of automation.
From the perspective of equipment, more and more attention has been paid to automatic and intelligent equipment to face the reality of expensive labor. However, there are many cheap labor forces in our country, which can be comprehensively utilized in combination with our national conditions, in line with the general law of market development. In particular, the specifications of domestic steel cutting, stirrup and steel mesh are extremely non-standard.
From the aspect of production organization, preciseness and high efficiency are the goal, which requires that the equipment is suitable for the national conditions, the capacity is matched, the production organization is scientific and the logistics is smooth. In BSW company of Germany, the production process is generally controlled by computer, for example, the production of welded wire mesh, from cold rolling of wire rod to straightening, welded wire mesh to cutting, label printing to warehousing, all of which realize computer automatic control. This not only reduces the labor intensity, improves the production efficiency, but also avoids the possibility of human error to the greatest extent.
In terms of the selection and use of raw materials, it emphasizes the best use of materials and scientific norms. In the aspect of steel deep processing, the demand for raw materials is also higher and higher. Due to the increasing variety of downstream deep processing, how to select and use appropriate raw materials scientifically and reasonably is becoming more and more important. For example, in BSW company, the raw materials are mainly divided into two categories: one is to roll the cold-rolled ribbed bars into cold-rolled bars for welded wire mesh; the other is to roll the hot-rolled deformed bars into cold drawn bars for bent hoops or directly sold as finished products. In order to meet the requirements of different types of products, the two kinds of raw materials are divided into different strength grades. As for the raw materials of hot rolling, the technologies of steel refining, high-speed cold rolling without torsion control or bar control rolling and control cooling are very common.
Since the development of steel deep processing industry in Europe, there are more and more varieties and branches, almost involving all sectors of the national economy in the application field; the specialized division of labor is also increasingly meticulous, emphasizing the comprehensive application of materials, chemicals, metal pressure processing, surface treatment, machinery manufacturing, electronics and information technology, which also requires the comprehensive skills of professional technicians and the level of operators. It's very important.
It is an inevitable development direction of the construction industry to improve the factory processing degree of the construction steel bars and realize the commercialization and professional distribution of the steel bars. I believe that with the advantages of deep processing products of steel bars known to people, there will be a broad market space, and China will also introduce more and more detailed and scientific standards and specifications. In the process, there will be many difficulties, and a lot of detailed work needs to be done. The key is to establish a long-term supply relationship with upstream and downstream enterprises of steel bars.
According to China's economic development trend and steel consumption, it is estimated that by 2020, the proportion of steel processing and distribution in China will reach about 10% of the steel consumption, i.e. 16 million tons.
