Hot rolled ribbed bar qualified only Liucheng

7, the product sample pass rate of 60.1%. Sampling results show that, first, better product quality, medium and large enterprises, small businesses a lower sampling rate of qualified products. The large, medium and small business product sample pass rates were 92. , 85.2% and 46.50 / 0. Second,[link widoczny dla zalogowanych], product quality spot checks at construction sites, many problems, product sample pass rate of only 37.5%. Third, without the production license of the company's products sample pass rate of 51.60 / 0 'than has been sampling the company's products production license together Jf ~ 77. Reflected in the main quality checks are: (1) Weight bias is epidemic. Weight bias is an important hot-rolled ribbed steel quality indicators, if the weight of negative bias greater cross-sectional area will reduce the steel, the corresponding mechanical properties will be seriously affected. The 97 kinds of samples of special checks the weight deviation project failed, accounting for 54.9% of the total number of random samples. Mainly due to dealers and trading steel construction units, generally paid by the delivery of steel root number,[link widoczny dla zalogowanych], one-sided pursuit of profit for some companies, the negative deviation of the standard production of products, and these enterprises due to technological level, process control lax and other factors, led to weight deviation lower than the standard product. (2) the mechanical process performance problems are more prominent. In this special spot checks,[link widoczny dla zalogowanych], there are 45 samples failed the mechanical process performance projects, accounting for 68% of the total number of random samples. First, the project mainly because of low weight deviation 26.2 percent. I failed, resulting in reinforcement of the cross-sectional area is too small, causing the mechanical process performance is mainly the second part of the manufacturers of raw materials quality control is lax, the use of raw materials not up to standard requirements. (5) Chemical exceeded. National standards for hot rolled ribbed steel bars made the chemical composition of strict regulations, excessive chemical composition is large, reinforced the mechanical process performance will be seriously affected. (4) non-standard grade is a grade signs to guide the construction unit in accordance with the specifications of the construction design requirements to select the appropriate type steel sign. In this special spot checks, there are 55 grades of the samples is not clear or non-standard signs, accounting for 15.1% of the total number of random samples. Mainly due to the management of enterprises lack of understanding of national standards. Production -0, business name specification model key failed projects LT.
