Telecom manufacturing leader Huawei company in a number of technology research and development field has entered the territory of no one, is the world's most outstanding Made in China label. Dong Mingzhu, CEO of Gree Electric Appliances, has been saying "let the world fall in love with Made in China". Recently, Dong Zong gave a motivational speech, "If you want to scold entrepreneurs, because we did not let Made in China stand up". "Made in China 2025" is a major plan for China's overall national strength and national security. Chinese entrepreneurs shoulder the mission of "manufacturing power".

Has shandong chang hua machinery technology CEO Zhong Xia rui accepted "the manufacturing sector net" in an interview, no national boundaries of science and technology, in terms of papermaking equipment manufacturing industry, the heaviest if study and draw lessons from foreign advanced technology, through independent research and development of Chinese and foreign technical cooperation and internationally competitive technology, so as to get rid of China's paper industry dependence on expensive imported equipment.

The "Er Light machine" that was popular in the 1980s and 1990s

Why is "pomp gone"?

Shandong Changhua Machinery Technology Co., Ltd. has a history of 50 years, formerly known as the second light industrial machinery factory in Shandong Province, and is called "Shandong Second Light Machinery" in the industry. Was very scarce in industrial technology in the 80 s and 90 s, shandong ErQing machine is one of the few domestic papermaking industry "and" technology, paper machine from all over the great river north and south in our country, cultural paper, wrapping paper, toilet paper, specialty paper, all kinds of machine, quantity is more than 1000, in a certain extent promote the development of China's paper industry, provides the technical support for many papermaking enterprises.

Zhong Xiaorui graduated from Shandong University of Technology, majoring in machinery. From 1998 to 1998, he served as technician, workshop director and deputy director of Shandong No. 2 Light Industry Machinery Factory. Director and Party Secretary of the factory in 1999; He has been the chairman and general manager of Shandong Changhua Paper Machinery Co., LTD since 2001.

In 2001, when Zhong Xiaorui served as chairman of the board, it was the year that China joined WTO. At that time, zhong Xiaorui, who was 30 years old at that time, made a grand statement of "building world-class papermaking equipment", trying to beat the competition by increasing technological research and development and importing equipment. When Germany Voith super large paper machine appeared in China plant, its modernization and advanced are amazing! Chinese paper equipment to contend with it is simply "egg against stone". Andriz, Metso, Voith three multinational companies gradually nipped the Chinese market, domestic paper machine orders dropped sharply every year, the grand situation is no longer.

Chinese and foreign technical cooperation, to create first-class

Chinese paper machine, regain glory

Over the years, Zhong xiaorui has led a scientific research team of more than 50 people in the company's technology R&D center to tackle technological problems, from independent innovation, integrated innovation to sino-foreign technical cooperation. We have cooperated with ANDRITZ of Austria, VAAHTO of Finland, ABK of France, KUSTERS of Germany, UMV of Sweden and other companies, and cooperated with Shandong University, Qilu University of Technology, Shaanxi University of Science and Technology and other colleges and universities. We draw lessons from foreign advanced technology and design concept to create first-class Chinese paper machine. Complete sets of paper machine equipment in the system integration, automation, paper technology, energy saving and consumption reduction and components can reflect the excellent cost performance of China's first-class paper machine.

Zhong Xiarui said, our goal is only one, to become a first-class Chinese paper machine, to provide customers with the largest economic value chain, the excellent cost performance of paper machine so that customers reduce investment costs, production costs, quickly improve the level of profit; Let Chang Hua paper machine regain glory.

Industry analysis, in addition to high-grade coated paper, liquid wrapped paper paper, packaging paper, special paper, cultural paper and other paper can consider the application of upgraded Chinese paper equipment. With the opportunity of the in-depth adjustment and optimization of China's paper industry, the potential market of paper equipment is still very big. We hope that Chinese paper enterprises can learn more about the optimized and upgraded Chinese paper equipment. Only by developing together and giving it the market can we make it strong and realize the dream of China's manufacturing power faster.

Scientific research Achievements of Attached Changhua Machinery Company:

1. Boot press technology

The technology passed the science and technology appraisal of Shandong Province in July 2015. The appraisal opinion fully affirmed the innovative achievements of the boot type press equipment: (1) invented a new structure of the boot type press, the formation of four areas between the boot plate and boot sleeve: static pressure area, dynamic pressure area, unloading area, oil level holding area, can form a good lubrication and pressure distribution interval. (2) the invention of a compensable skeleton oil seal and wear-resistant sleeve sealing form, sealing service life is long, sealing effect is good; A sealing part with four-side concave structure is invented to make the sealing between boot cover and rotating mechanism reliable and large pressing force. (3) In order to adapt to the high line pressure alternating stress condition, a new roller forging technology is developed. (4) The overall technology has reached the international advanced level.

2. Inertia shaking box technology

The high frequency vibration of the chest roller optimizes fiber orientation and provides excellent shaping results for all paper machines. The paper quality can be improved obviously, which is conducive to the subsequent processing, coating, impregnation and printing of paper. And can effectively improve the paper uniformity, reduce the paper vertical and horizontal tensile strength ratio. It has obvious improvement on other quality parameters such as burst resistance and scT-CD. And no reaction force, no impact on the foundation.

Shandong Changhua company has developed an inertial shaker that utilizes the self-balance of the eccentric system and the high synchronization of the CNC servo system. The design structure is simple and reliable, no complex hydraulic system, maintenance free. Successfully applied to special paper machine and carton paper machine.
