Lately, the project of “Intensive Super-large Scale High- performance Passenger Car Radial Tire Production System and Engineering Key Technology” smoothly passed the science and technology achievement appraisal of Chinese Petroleum and Chemical Industry Federation (hereinafter referred to as CPCIF) and the appraisal experts thought that the overall technology reached the international advanced level, in which the design theory and method of prestressed concrete structure of secondary internal force reached international leading level.

This project was jointly developed by Zhongce Rubber Group Co., Ltd., ChemChina Guilin Engineering Co., Ltd., Tongji University and Shanghai Tongij Building Engineering Design Co., Ltd. It took intensive mode of production as the pointcut to integrate various production factors, innovatively adopted intensive super-large scale continuous 3D tire production process combined system, overally considered the design theory and method of prestressed concrete structure of secondary internal force to study and solve the technical problem of super-long concrete structure, design and build super-long bi-directional prestressed concrete structure factory building with the total building area of single factory building as 266,000 m2, change the traditional discontinuous 2D plane production system, realize continuous and automatic 3D production of high-performance passenger car radial tires whole production process and obviously increase the production efficiency, save the resources and improve the production environment. Meanwhile, through improvement of system technologies in various aspects such as desulfurization air supply, intelligent ventilation, comprehensive energy utilization, etc., it effectively reduced the energy consumption and the unit consumption of tire energy reached international advanced level. Various performances of high-performance passenger car radial tires produced by this system reached or exceeded the American DOT standard and EU ECE117 product second phase international green tire standard.

Application of this achievement could effectively improve the tire manufacturing level and product quality, save the land, reduce the investment cost, save the energy and reduce the consumption, lower the production cost and drive advanced manufacturing and automation in tire production field.
