On June 12, the National ISP Technology Innovation Symposium and the Founding Conference of China ISP Technology Innovation Alliance were held at the China Aluminum Technology Building in Changsha, Hunan. The purpose of this meeting is to promote the development of ISP pyrometallurgy technology and equipment in China, to further play the advantages of ISP process technology, reduce energy consumption, improve efficiency, comprehensively improve the competitiveness of key ISP technologies, and benchmark the world's leading ISP enterprises to promote The fire zinc smelting technology is sustainable and healthy. The meeting was sponsored by Changsha Nonferrous Metallurgy Design and Research Institute Co., Ltd. (hereinafter referred to as "Changsha Nonferrous Institute"), and Zhongjinling Nanshaoguan Smelter, Shaanxi Dongling Smelter Co., Ltd., and Baiyin Nonferrous Group No. 3 Smelter participated in the meeting.
Tan Ronghe, general manager of Changsha Nonferrous Metals Institute, delivered a welcome speech on behalf of the company. He reviewed the cooperation process between Changsha Nonferrous Metals Institute and various ISP manufacturing enterprises across the country, and looked forward to the development direction of ISP technology innovation. Zhao Xiaoqiang, general manager of Shaanxi Dongling Smelting Co., Ltd., Zeng Pingsheng, deputy director of Zhongjinling Nanshaoguan smelter, and Yu Jianzhong, deputy director of Baiyin Nonferrous Metals Group's third smelter, introduced the production status and economic indicators of ISP pyrometallurgical smelting enterprises And technical bottlenecks. Prof. Zhang Leru, a national nonferrous metal industry design master, interpreted the Ministry of Industry and Information Technology's "Lead and Zinc Industry Standard Conditions" (2020 version), and discussed from the aspects of comprehensive utilization of resources, environmental protection, energy consumption, automatic control and technical development direction. Professor He Xingmin, a national nonferrous metal industry design master, conducted a comparison of indicators between the ISP fire zinc smelting process and the wet zinc smelting process. Zhang Ling, senior engineer of the R&D Center of Changsha Nonferrous Metals Institute, introduced the application of key oxygen-rich pulverized coal injection technology in molten pool smelting.
The meeting unanimously agreed to establish the China ISP Technology Innovation Alliance. The chairman of the alliance will be rotated by Changsha Nonferrous Metals Institute, Shaoguan Smelter, Shaanxi Dongling Smelting Co., Ltd., Baiyin Nonferrous Metals Group No. 3 Smelting Plant, Huludao Zinc Industry Co., Ltd. The China ISP Technology Innovation Alliance will give full play to each unit's own advantages, form a production, learning, research and application technology innovation chain, work together to solve the key and common technical problems of ISP technology development, and accelerate scientific and technological innovation and achievements by building effective cooperation methods. Application, promote common progress of alliance members.
The simplest shape of the reinforcing ring is a rectangular column attached to the surface of the product, but in order to meet some production or structural considerations, the shape and size of the reinforcing ribs need to be changed as shown in the following figure. The position of the bottom of the product must be rounded to eliminate excessive stress concentration. The rounded corner design also gives the runner a gradual shape to fill the cavity with curvature. Problems such as water trapping will also lengthen the production cycle and increase production costs.
