Special guest wonderful report sharing

Topic: China's manufacturing 2025 and intelligent manufacturing policy analysis

Speaker: Yang Ye North China University of Technology

At present, the global manufacturing industry is facing great pressure of transformation. On the one hand, there have been great changes on the demand side: the personalized demand of consumers has increased, and the delivery time is shorter; the improvement of energy and environmental protection requirements has led to lower energy consumption and more efficient use of resources. On the other hand, the deep integration of the new generation of information technology and the manufacturing industry is profoundly affecting the development and transformation of the manufacturing industry: such as the development of cloud computing, big data, artificial intelligence, and industrial Internet of Things. In the face of such challenges, developed countries and international giants have stepped up their layout to reshape new competitive advantages in manufacturing. And China put forward the 2025 of China's manufacturing, the revitalization of the manufacturing industry as a national strategy to promote. National and local governments have issued a series of policies. Encourage enterprises to implement intelligent manufacturing for transformation and upgrading. The Ministry of Industry and Information Technology defined the five-year development plan for intelligent manufacturing in the 13th five-year Plan issued and implemented in 2016; Academician Zhou Ji of the Chinese Academy of Engineering put forward the discussion of "moving towards a new generation of intelligent manufacturing". At present, the industrial Internet, big data and artificial intelligence have achieved group breakthroughs and integrated applications. Informatization characterized by a new generation of artificial intelligence technology has created a new stage of digitalization, networking and intelligent manufacturing. In such an environment, manufacturing enterprises should actively carry out intelligent transformation, seize the opportunity, adjust measures to enterprise conditions, and realize all-round modernization transformation and upgrading.

Topic: Discussion and exchange of the concept of "environmental protection" in metalworking fluids

Speaker: Liu Gang Shanghai Hongze Chemical Co., Ltd.

Pure oil vs water based. Which environmental protection?

Oily and oil-free. Which environmental protection?

Vegetable oil vs mineral oil. Which environmental protection?

Which raw materials are more environmentally friendly?

Do environmental regulations in Europe, America and Japan represent an advanced direction?

Topic: Study on the lubricating properties of castor oil and its application in metal processing

Speaker: Qian Shanhua Jiangnan University

With the continuous development of the performance of modern machinery and equipment and the increasingly stringent environmental requirements, higher requirements are put forward for lube base oils and additives. Biodegradable and environmentally friendly lubricants have become the trend to replace traditional mineral oil-based lubricants due to their low pollution and high wear resistance. As a traditional environment-friendly lubricating oil, vegetable oil has the advantages of low cost, abundant source and renewable. Castor oil, which belongs to the non-food bio-energy category, not only has the general characteristics of vegetable oil, but also has better polarity, lubricity and antioxidant properties than other vegetable oils because of the hydroxyl group on the 12th carbon atom of ricinoleic acid.

Topic: Application of chemical mechanical polishing technology in ultra-precision manufacturing of industrial parts

Speaker: Jiang Liang Southwest Jiaotong University

Chemical mechanical polishing technology is widely used in the manufacture of ultra-large-scale integrated circuits. Through the synergy of chemical reaction and mechanical force, it can achieve sub-nano-scale surface roughness and nano-scale surface accuracy on silicon wafers and other planes, as well as surface defects close to zero and damage layer thickness close to zero. To this end, the chemical mechanical polishing technology is extended to the ultra-precision manufacturing of industrial parts to achieve its ultra-precision surface processing. Taking the bearing steel material parts as the research object, first, the macro-influence law and mechanism of each polishing liquid component on the polishing performance of bearing steel are systematically studied, and then the micro-material removal mechanism of bearing steel under the mechanical and chemical coupling effect is studied by atomic force microscope. The related research can provide a useful reference for the ultra-precision manufacturing of industrial parts.

Topic: Control and management of metalworking fluids

Speaker: Zhou Dafeng Suzhou Hault Chemical Co., Ltd.

Many companies often attach importance to the development and improvement of the formulation of metal working fluid, but ignore the control and management of metal working fluid on site. The field control and management of cutting fluid seems simple, but it plays an important role in the service life and processing efficiency of metal working fluid.

1. Control of bacteria

2. PH value control

3. Control of concentration

4. Management of liquid distribution

5. Use of system cleaning agent

Topic: Formulation Design of Rolling Oil and Selection of Additives

Topic: Research on treatment and reuse technology of metal working fluid wastewater

Speaker: Li Xiaolei Tsinghua University Tianjin High-end Equipment Research Institute

Metal processing fluid, in the industrial manufacturing to play the role of lubrication, cooling, rust prevention, cleaning, most of the metal processing must rely on good metal processing fluid. However, the metal working fluid has a certain service life, with the use of time to extend its performance will gradually decay until failure, at this time the formation of metal working fluid waste. The composition of the processing liquid waste liquid is complex, the organic matter content is high, and the system is stable, and it has been called the "cancer water" in the industrial wastewater ". This report will focus on relevant metalworking fluid waste treatment technologies and introduce practical examples of metalworking fluid reuse by lubrication companies.
