Spiral enterprise production license threshold will be further improved

It is reported that since 1987, the production license for the construction of reinforced bars has passed five renewal permits. According to the new version of the "Implementation Rules for Construction Reinforcing Steel Products Production Licenses," a new round of replacement (issuance) certificates will be launched soon.

On June 14th, the “Plan for the Implementation of the Manufacturing Permit for Construction Steel and Prestressed Concrete Products for Steel Products” was held in Nanjing. Steel and Steel Information learned that more than 400 spiral production enterprises from all over the country have brought together Nanjing. , This meeting is expected to 800 participants, but the final statistics show that the national spiral enterprise has come to more than 1,000 people.

The organizer of the event, the National Construction Steel Quality Supervision and Inspection Center, is responsible for the staffing table of the No. 6 Reception Group. They are mainly responsible for the conference reception of the representatives of the steel factories in Guangdong and other places. “Most of the steel mills have come, only a few are signing on behalf of companies, and more than dozens of companies have been added (without booking) than expected.” The hot scenes of the participants indirectly reflected the importance the steel mills attached to this meeting.

This seemingly ordinary meeting means that a new reshuffle will soon begin. At the same time, the quality of construction steel that has been plagued by the industry for a long time will be rectified from the source of production. A spiral production license is also being brewed behind it. Battle for the war.

The National Industrial Product Licensing Office stated: “One of the basic spirits of changing certificates is to raise the level of industrial development, eliminate backward production capacity and equipment, and improve product quality.”

A representative from a steel production company in Wu'an, Hebei, said: "I came before this conference to push off all the meetings. This is directly related to whether or not we can produce in the future. This is a matter of life and death for an enterprise."

The relevant report was learned from the National Construction Steel Quality Supervision and Inspection Center that the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) had issued a production license for 25 steel companies that had not been replaced at the time of the April 30, 2010, State Administration of Inspection and Quarantine [2010] notice. Logout. If these enterprises reapply, they will apply according to the newly declared companies.

In this regard, relevant persons also stated that “in the process of issuing certificates, a large number of small companies have not been certified because they do not meet the basic conditions.” All previous certifications have played a positive role in promoting industrial restructuring of the industry. "Most companies that have already obtained evidence have carried out technological transformation of the original technology and equipment."

Recent phenomena such as the protection of houses and high-speed rail projects, such as "bars" and "slimming bars," have pushed spiral production quality problems to the top of the curve. In the eradication of such issues, the production license system has played an important role for many years.

Li Yuanping, spokesperson of the General Administration of Quality Supervision, Inspection and Quarantine, publicly stated that nine ministries and commissions, including the General Administration of Quality Supervision, Inspection and Quarantine, have jointly issued and issued documents. This year's special rectification will focus on solving a number of outstanding issues involving personal and property safety, and issues such as “thinning steel bars” will be severely cracked.

Zhu Jianguo, director of the National Construction Steel Quality Supervision and Inspection Center, pointed out that in recent years, the State Construction Steel Quality Supervision and Inspection Center has collected statistical data on the industry and said, “The main reason for product failure is the weight of the negative deviation.”

Regarding the reason why construction steel products failed to appear on the market, Zhu Jianguo explained to this reporter: “On the one hand, when the market is in a fierce competition, companies in order to reduce production costs, improve efficiency, or obtain a living space, management The weight deviation internal control index is set to the lower limit value to organize production. Individual companies even use super-negative bias to produce; on the other hand, some steel companies also meet the requirements of middlemen and deliberately produce such negative deviations or even exceed them when pursuing profit maximization. Negative deviation product."

In addition, certain loopholes in market supervision also provide a "soil" for the appearance of negative deviation products.

When the steel products enter the construction site, the sampling inspection of the steel bars is mainly to measure the mechanical and process properties of the steel bars, and there is no requirement for the weight deviation items, which is one of the reasons why negative deviation products can exist.

In response to this problem, the national standard "Code for Acceptance of Construction Quality of Concrete Structures" GB50204-2002 has been revised, and the weight deviation project will be regarded as a mandatory inspection item for site acceptance, and will be implemented on August 1 this year. Moreover, this item also serves as a verification item for the certificate. "We can control the quality of the rebar from the source and eliminate the negative deviation of the rebar beyond the national standard into the construction site."

As the controlling shareholder of Wenzhou Yanggang Rolling Mill, Ye Huichang, chairman of Wenzhou Metal Investment Co., Ltd., told the reporter: “The state will guard against ultra-bias tolerances and production licenses. No company has dared to take this risk. It is directly related to the question of whether the enterprise can survive. This avoids the proliferation of production of super-negative tolerance from the source."

"At the current stage of development, corporate self-discipline alone cannot solve the problem completely." The production license system must be used for administrative intervention. “However, this production license is actually an inspection and inspection of construction steel standards and the implementation of inspections.”

It is understood that hot-rolled ribbed steel bars have been implementing national mandatory standards. Starting from July 1 this year, the industry will formally implement the new "concrete structural design specifications" and other new standards for construction steel. In 2010, the total output of hot-rolled ribbed steel bars in China reached 130 million tons, accounting for about 20% of China's annual steel output. Mainly concentrated in Jiangsu, Hebei and other places.

To this end, the implementation details of the production license for reinforced steel products have also been updated and adjusted in a timely manner, reflecting the technical content of the new standard. For example, the strength grade of the steel bar, chemical composition, new welding carbon equivalent requirements, weight deviation index, tip shear integrity.

In addition, the country’s industrial policy also imposes higher requirements on the industry. At present, the steel bars produced by Chinese enterprises are basically HRB335 and HRB400. However, HRB335 and HPB235 will be listed as phase-out products in the "Guidance Catalogue for Industrial Structure Adjustment (2011 Edition)" that has just been released this year. It will also speed up the promotion of 400 MPa or more steel reinforcement.

The recertification of production licenses will greatly promote the implementation of new standards for construction steel and national industrial policies. “The production technology of the steel plant has risen to a certain height. It is time to raise the standard.” Zhu Jianguo revealed that the next step will be to tighten the upper and lower tolerance ratios of the hot-rolled ribbed steel bar production and increase the overall quality control again.

Zhu Jianguo revealed at the meeting that the number of hot rolled ribbed steel bars nationwide has dropped from nearly 1,000 in 1999 to the current 345, and the number of steel-making enterprises in particular has dropped to 161. This number will be further reduced in the future. In this regard, steel and steel information collation of relevant data learned that, with the elimination of backwardness, mergers and reorganization, standardization of iron and steel production and management work, the production license will be issued more and more requirements, the threshold will be further improved.

Wang Jun from the AQSIQ exemplifies the case at the meeting. In terms of output scale, when the certification was issued in 1993, only the annual output of hot rolled steel was required to be at least 3,000 tons and steel bars were at least 500 tons. In this certification, the company was required to Annual output of 100,000 tons of steel (300,000 tons in 2002), and small steel products with 100,000 tons of small profiles (250,000 tons in 2002) and hot-rolled ribbed steel bars of 20,000 tons or less may not be certified.
