Analysis on the influence of steel consumption in China's construction machinery industry

at present, the overall quality level of steel used in China's construction machinery is not high, and only about 30% of the physical quality of products has reached the international advanced level. The direct consequence of this phenomenon is that compared with similar foreign products, China's construction machinery products still have a large gap in durability and reliability

China has now become the largest construction machinery market in the world. As the most important raw material of construction machinery, steel not only determines the price of products, but also determines the performance and reliability of products. According to Luo Baihui, chief researcher of Jinmo machinery, the self-sufficiency rate of most varieties of steel for construction machinery in China has reached 100%, and the production of key steel materials such as high-strength building steel plates, high-strength threaded steel bars for earthquake resistant buildings, alloy materials for spacecraft, high-performance pipeline steel has made great progress. At the same time, the steel market for construction machinery in China has not been fully developed, and some high-end steel needs to be imported. On the whole, at present, China's engineering machinery, automobile, parts, metal products and other industries will reduce 18 jobs. The overall quality level of mechanical steel is not high, and only about 30% of the physical quality of products has reached the international advanced level. The direct consequence of this phenomenon is that compared with similar foreign products, China's construction machinery products still have a large gap in durability and reliability

Luo Baihui said that as an industry with more steel consumption, construction machinery consumes more than 1.2 million tons of steel annually, including about 600000 tons of medium and thick plates; Pipes (including seamless steel pipes and thick pipes) are about 120000 tons, accounting for about 10%; The annual consumption of bars is 150000 tons, accounting for 13%; Hot rolled sheet and cold rolled sheet are 250000 tons, accounting for about 21%; Other steels account for about 7%

although construction machinery digests a lot of steel production capacity every year, due to the technical constraints of the domestic steel industry, the steel market for construction machinery has not been fully developed, and some high-end aluminum powders are widely used, in large demand, and many varieties of steel need to be imported. For example, 60~100 kg construction machinery plates, although China has achieved mass production, high-strength construction machinery plates still have the problems of low qualification rate and low surface quality. Wear resistant plates can also basically meet the needs of construction machinery, but high-end products still rely on imports. Although high-quality bars are fully capable of supplying the domestic market, they cannot be widely used because of their stability and steel varieties

Luo Baihui said that at present, the overall level of quality is not high, the stability is insufficient, the downstream industry has not yet been able to use steel efficiently and scientifically, and has not yet formed a service system for the downstream industry to provide complete material solutions, which has become the biggest problem restricting China's construction machinery steel market. After nearly a decade of development, although this problem has eased, it still can not meet the needs of China's construction machinery for high-quality steel

the quantity and price of steel for construction machinery rose at the same time.

Li Xinchuang, Executive Deputy Secretary General of China Iron and Steel Industry Association, said that according to the overall development trend of the machinery industry in 2013, considering the role of agricultural machinery, electrical appliances, petrochemical general machinery and other industries in stimulating consumption, it is expected that the steel consumption of the machinery industry will maintain a low-speed growth trend in 2013, and the annual steel consumption is expected to reach 131 million tons, an increase of 4.8% year-on-year

the construction machinery industry is one of the sub industries with the largest steel consumption in the machinery industry. Last year, 15.2 million tons of steel were consumed, accounting for 12.2% of the steel consumption in the machinery industry and 2.3% of the total steel consumption. The steel used in the construction machinery industry has the characteristics of many varieties and a wide range of specifications. The consumption varieties are mainly medium and heavy plates, high-quality bars and sections

the construction machinery industry has the largest consumption of medium and heavy plates, accounting for 63.1%; The second is bar, accounting for 20.0%; Profile accounts for 8.1%; Other steel products account for 8.8%. Construction machinery board 60~100kg grade construction machinery board has achieved mass production in China; Large iron and steel enterprises such as Baosteel and Angang have developed 100kg high-strength construction machinery plates; However, high-strength construction machinery board still has the problems of low qualification rate and low quality, which is a hard injury restricting the price

according to the statistics of the changes in the sales profit margin of iron and steel enterprises from 2001 to 2012, a high profit level was maintained before 2007, and 2004 was the most certain wear of parts in recent years or the high wear value of individual parts was 8.0%; Since 2008, the profitability of China's iron and steel enterprises has decreased significantly, the sales profit margin has fallen sharply, and the iron and steel industry has fallen into business difficulties

in 2012, China's steel price has been at a low level in recent years, and it is expected that this year's steel price level will be higher than that of last year. However, because deep-seated problems such as overcapacity and homogeneous competition cannot be solved in a short time, steel prices are difficult to rise significantly compared with last year. From the perspective of the whole year, China's steel prices are generally expected to show a trend of low before high and fluctuating upward

strengthen cooperation for a win-win situation

the leading products of the construction machinery industry include a full range of products such as concrete machinery, road building machinery, excavation machinery, piling machinery, hoisting machinery and wind power equipment. Many products in this industry need a large number of high-quality steel as raw materials
