At the meeting, Wang Chunxi, director of the Standards and Inspection Center of the Institute of Instrument and Meter Technology of the Ministry of Machinery Industry, stated that China has become a manufacturing powerhouse, but it is still facing stiff constraints on resource and environment, low product quality, and lack of innovation and core competitiveness. , irrational industrial structure and many other issues. In order to deal with the severe situation of “two squeezes†in China's manufacturing industry, we must seize the strategic heights of technological development, lead the development of smart equipment industry in areas such as intelligent robots and 3D printing manufacturing, and innovate the creative design industry, manufacturing service industry, and smart manufacturing base. Safeguard industries and other modern service industries to seize the commanding heights.
According to reports, the Ministry of Industry and Information Technology established a working group on smart manufacturing standards in February 2015. On December 29, 2015, the Ministry of Industry and Information Technology of the People's Republic of China and the National Standards Committee jointly issued the “Guidelines for the Construction of a National Smart Manufacturing Standard System†(hereinafter referred to as the “Standard Guideâ€). The "Standard Guide" focuses on the manufacturing industry's advantageous areas and takes into account the transformation and upgrading of traditional industries. It follows the principle of "commonality first, emergency first" and is mainly aimed at cross-domain and cross-industry system integration standards.
The "Standard Guide" specifies the general requirements, construction ideas, construction content, and organization and implementation methods for building a smart manufacturing standards system. From the three latitudes of life cycle, system level, and intelligent function, the intelligent manufacturing standard system architecture was established. An intelligent manufacturing standard system framework was proposed. The framework includes five basic commonalities such as basics, safety, management, inspection and evaluation, and reliability, and five key technologies such as smart equipment, smart factories, intelligent services, industrial software and big data, and industrial internet. Standards and application standards in different industries.
The Smart Manufacturing Integrated Standards Working Group brings together forty to fifty outstanding experts from various industries across the country. It is supported by the China Electronics Technology Standardization Institute, the Institute of Instrument and Meter Technology of the Ministry of Machinery Industry, and the China Institute of Information and Communications, and is responsible for the information field and equipment, respectively. Smart Manufacturing Standardization Work in the Field and Industrial Internet Sector. At present, the working group is preparing an "Understanding of the National Smart Manufacturing Standards System Construction Guide," which is expected to be released in June this year.
It is understood that the next step is to focus on the standardization of work: First, reference RAMI4.0 standard mapping, refine the intelligent manufacturing system architecture, positioning the existing standards and the lack of intelligent manufacturing system architecture. The second is to develop a common basic standard for intelligent manufacturing, and to study the basic common technology and application of NQI in the basic commonality and key technical standards of smart manufacturing. The third is to carry out the development of special standards for smart manufacturing basic application projects and application standards for new model projects, and establish pilot demonstrations for smart manufacturing to promote the application of enterprise intelligent manufacturing standards. The fourth is to carry out extensive international cooperation to ensure the cross-regional and cross-domain characteristics of smart manufacturing standards.
Hastelloy Alloy is a nickel - based corrosion - resistant alloy, which is mainly divided into nickel - chromium alloy and nickel - chromium - molybdenum alloy.Hartford alloy has good corrosion resistance and thermal stability, and is widely used in aviation and chemical fields.
Monel Alloy series products have excellent physical properties of high strength, high corrosion resistance and wear resistance.In all kinds of acid and alkali medium, it has the advantage of long service life, so it is widely used in petrochemical industry, nuclear industry, national defense industry and other advanced industries, as an important part and other industries under complex environmental conditions with high strength, high corrosion resistance and high abrasion resistance.
Uniform corrosion of Inconel products can occur in acidic or hot alkaline solutions.Through this mechanism losses can be expected and allowed in the design.Inconel products corrode at a very slow rate when the metal is in a passive state. Generally corrosion resistance is better with a larger chromium content, but other solutes can be harmful.
