寿县合兴钢结构浅谈建筑用钢占总钢用量的比重

发布时间:2016-8-27 9:55:12 浏览次数:585

近数十年来,前苏联、美国、日本三个国家一直是国际上钢产量居前三位的国家,其钢产量轮番位居国际第一位。因而,这几个国家的修建钢构造建设事业蓬勃开展。而在同一期间,我国在这方面的开展则对比缓慢,水平也相对落后。近几年来,跟着我国改革开放政策的实施和推进,我国的经济建设工作取得了日新月异的开展。在此期间,我国的钢产量一跃变成国际第一位。

1996年,我国钢产量初次打破亿吨大关;1998年我国钢产量已达11434万t,并且每年增产300万t.钢产量的增加为开展我国修建钢构造建设事业创造了极好的机遇。但现在,我国与兴旺国家比较在许多方面还存在着显着的距离,因而,为了推动我国修建钢构造的进一步开展和使用,我们急需了解国外修建钢构造的使用概略。


    我国的修建用钢总量约占悉数钢产量的20%~25%,而工业兴旺的国家则占30%以上。如美国和日本,该项目标均已超越50%.在我国,钢在修建中主要用于修建用钢构造,钢筋混凝土用钢筋,钢绞线,钢丝,门窗等,而其中钢构造用钢只占10%摆布,在我国一亿吨的钢产量中,真实用于钢构造上的也就200~300万吨。


    依据1998年中期美国金属修建行业散布的一些数据,美国金属修建行业的开展和市场的基本情况是:在20世纪50、60、70、80和90年代,以百万美元计的年销售额/以万吨计的年加工量别离为150/30、300/65、1200/110、1500/125和2200/190,如以50年代为例相应的增加倍数别离到达1、2/22、8/37、10/57和15/6.3倍。从中能够看出,美国的修建用金属年;销售额增加很快,估量现在已经超越25亿美元,年加工量也已经到达200万吨以上。

In recent decades, the three countries of the former Soviet Union, the United States, Japan has been the steel output ranked the top three countries, the output of steel turns ranked first in the international. Therefore, these countries, the construction of a steel structure construction enterprise vigorous development. While in the same period, China's development in this area is relatively slow, the level is relatively backward. In recent years, with the implementation of China's reform and opening up policy, China's economic construction has made rapid progress. During this period, China's steel production has become the first international.


In 1996, China's steel production for the first time to break the million tons; in 1998, China's steel output has reached 11434 million tons and annual yield increase of 300 million tons of steel production for the development of China's construction of steel structure building construction has created great opportunities. But now, our country and the developed countries compared in many ways still exist significant distances, so in order to promote our country to build the steel made the further development and use, we need to understand the foreign building steel using sketchy.


The total amount of steel in our country is about 25% to 20% of the total steel production, while the industrial developed countries account for more than 30%. Such as the United States and Japan, the project have exceeded 50%. In our country, steel construction is mainly used for building made of steel, steel bars for concrete reinforcement, steel wire, steel wire, doors and windows, and the steel steel accounted for only 10% the left and right sides, in China 100 million tons of steel production, true for steel manufacture is 200 ~ 300 million tons.


According to the 1998 mid American metal construction industry spread some of the data and the metal building is the basic situation of the development of the industry and the market: in the 20th century 50, 60, 70, in the 1980s and 1990s, in millions of dollars in annual sales / with tons of annual processing capacity of parting 150/30 / 65, 1200/110, 1500/125 and 2200/190, such as during the 1950s, as an example the corresponding increase multiple parting reached 1, 2 / 2. 2, 8. 7, 10 / 5. 7 and 15/6.3 times. Can be seen from the United States, the construction of the metal in the year of the increase in sales of very fast, now has more than 2 billion 500 million U.S. dollars, the annual processing capacity has reached more than 2 million tons.
