Ordinary hot-rolled steel grades by the HRB and their grades constitute the minimum yield point. H, R, B, respectively, for the hot-rolled (Hotrolled), ribbed (Ribbed), steel (Bars) the first three words of the English alphabet. Hot-rolled ribbed steel bars into HRB335 (old number 20MnSi), HRB400 (old number 20MnSiV, 20MnSiNb, 20Mnti), HRB500 three grades. Its fine grain grades of hot-rolled steel in the hot-rolled ribbed steel acronym plus "fine" in English (Fine) first letter. Such as: HRBF335, HRBF400, HRBF500. Seismic structure with higher requirements applicable grades: grades have been added after the E (for example: HRB400E, HRBF400E). Main Uses: Widely used in civil engineering construction of buildings, bridges, roads and so on. The main origin: rebar production mainly in the home country of the North China and Northeast China, North China, such as Shougang, Tangshan Steel, Xuanhua Steel and Chengde Steel, Xinxing Ductile Iron Pipes, Shanxi Zhongyang Steel, Baoding Puri steel, Northeast regions such as Jianlong, amoxicillin, North Terrace, Fushun Special Steel, etc., these two regions accounted for over 50% of the total production of rebar. The difference between rebar and plain bars: the difference between the rebar and plain bars of the surface with longitudinal ribs and transverse ribs, usually with two longitudinal ribs and channels evenly distributed along the length of the transverse ribs. Is a small steel rebar steel, mainly used for the skeleton of reinforced concrete building components. In use requires a certain degree of mechanical strength, flexural deformation properties and process welding performance. Production of raw steel billets for the carbon structure was calm smelting process [1] From a macro point of view, or domestic steel prices fell sharply this year, China's steel product prices are expected to fall sharply this year, because there has been the problem of overcapacity, And the main raw material iron ore prices also fell. China's economic growth slowed in the country are suppressing demand for steel and iron ore, which dragged down the price of both commodities fell to multi-month lows, and the global iron ore producer's expansion plans at risk. Expected trends in the coming months will not change because of excessive production capacity and industry consolidation is too slow; Meanwhile the problem of excess supply of iron ore has also been increased, indicating that the price will continue to decline. Second, the IMF lowered China's GDP growth is expected. IMF held at 10:00 on May 29 press conference to introduce the relevant circumstances of the 2013 Article IV annual policy consultations with China and to answer a reporter's question, said that China's economy can still maintain the annual growth rate of 7.75%. Statistics Industry Insight Network "Chinese steel industry, special investigations" [2] show that coal tar steel futures fell together again, and the stock market stability, steel futures and stock market differentiation worse. The reason is the steel industry chain itself due to the intensification of conflicts between supply and demand fundamentals. Spot prices into the off-season after spending falling, businesses competing shipping prices, but has failed to inspire the desire to buy downstream. Also accelerate the decline of upstream raw materials, steel market reproduces the vicious circle turns on the downstream decline. Consumer demand will gradually shrink the off-season, while crude steel production to remain high, supply and demand will worsen macroeconomic no good, rebar worrying trend of late. Steel or low alloy steel, hot-rolled steel finished forming, normalized or steel commonly used classification in two ways: First, the geometry of the classification, according to the cross-sectional shape of the ribs and rib spacing different classification or type such as British Standard (BS4449), the rebar into type Ⅰ, Ⅱ type. This classification performance of the main reaction clenched rebar. Second, the performance of the classification (class), such as China's current performance standards, rebar (G B1499.2-2007) wire for the 1499.1-2008), press the intensity level (yield point / tensile strength) will be divided into rebar three grades; Japan Industrial Standard (JI SG3112), press the overall performance will be divided into five types of steel; British Standard (BS4461), and also provides a number of performance tests grade rebar. But can also be classified by use of the rebar, as divided by ordinary reinforced concrete and prestressed concrete reinforced with heat treatment and so on. Hot-rolled delivery. Rebar is a medium-sized building components must be steel, China's annual imports have some bulk. The main producing countries and regions as Japan, Western Europe. Rebar export growth in recent years, the number of major domestic export manufacturers in Beijing, Tianjin, Shanghai, Wuhan, Sichuan, Liaoning and other provinces of the iron and steel enterprises. The main exports to Hong Kong and Macao region and Southeast Asia. Imports of rebar cross rib geometry of the main square of the ordinary or common thread rhombus thread. Domestic rebar cross rib geometry mainly spiral, herringbone, crescent three. Ordering principle of rebar is generally required to meet the engineering design performance requirements clenched on the basis of the performance of mechanical process or mechanical strength index based.
