After carefully listening to the report of the project team, the experts believed that the smooth launch of the two projects marked the importance of technology in the theoretical research, structural innovation and equipment manufacturing level of oil film bearings, mainly in:
In view of the characteristics of Benxi Steel's high-strength thin slab continuous casting and rolling mill, the traditional design concept was broken in the theory and model of oil film bearing. By optimizing the design, the technical performance indexes and operating parameters of the supporting bearing products were better than similar foreign products, breaking the The monopoly of foreign companies in this field laid the foundation for the comprehensive localization of cold and hot rolling mill equipment.
Too heavy on the oil film bearing of Shougang 3500mm plate mill, the bearing capacity is adopted by the technology of keyless structure, double thrust full symmetry structure, hydraulic quick locking mechanism, improved foot seal and on-line temperature monitoring device. Large, stable operation, good sealing performance, convenient assembly and disassembly, reliable operation and so on.
The participating experts gave high praise. The oil film bearings of the two projects have independent intellectual property rights, and the overall level has reached the international leading level. Experts and representatives of steel mills encouraged and encouraged the promotion of technology and contributed to the improvement of China's heavy machinery and equipment.
The conference was hosted by the Science and Technology Department of Shanxi Province and invited experts and representatives from China Heavy Machinery Industry Association, Shanghai Jiaotong University, Taiyuan University of Science and Technology, Taiyuan University of Technology, Anshan Iron and Steel, Benxi Steel, Shougang, Wuhan Iron and Steel, Tiangang and Taigang. Identification meeting.
Two technical appraisals of TZ brand oil film bearings are highly evaluated
Taiyuan Heavy Machinery Group Co., Ltd. developed the "slab slab continuous casting and rolling mill ZYC1065-75WJ oil film bearing, ZYC1065-75WJJ oil film bearing, ZYC985-75WJ oil film bearing" and the Shougang 3500 plate mill for the high-strength continuous casting and rolling mill of this steel. The "ZYC1500-75WJ oil film bearing" developed by the company recently carried out scientific and technological achievements appraisal in Benxi City, Liaoning Province.
