On April 22, the group standard review meeting of China Metallurgical Construction Association was held in Beijing, and the standard of refractory materials for rotary hearth furnace edited by the company passed the review. The meeting was presided over by Wu Yuxia, director of the quality department of China Metallurgical Construction Association. Peng Dejiang, chief engineer of the company, Xu Deting, chief expert, and Li Qiang, minister of technology, attended the meeting.
"Refractory for rotary hearth furnace" standardizes the technical requirements of refractory materials for various parts of rotary hearth furnace for metallurgical solid waste treatment, provides guidance for the selection of refractory materials for rotary hearth furnace for metallurgical solid waste treatment, further exerts the significant advantages of rotary hearth furnace in metallurgical solid waste treatment, meets the environmental protection requirements of efficient utilization of resources in iron and steel enterprises, and contributes to the sustainable development of China's industry.
At the meeting, the statements of the three representatives were well received by the review group. Finally, the review committee unanimously agreed that the "refractory materials for rotary hearth furnace" passed the review.
The research and development of refractory materials for rotary hearth furnace for metallurgical solid waste treatment was initiated in 2014. The company's core technical personnel jointly undertook the key task of the project. Through laboratory tests and pilot tests in steel mills, the technical problems of poor corrosion resistance and short service life of castable in high-temperature section of rotary hearth furnace were solved, and the service life of rotary hearth furnace for metallurgical solid waste treatment met the requirements of high-load metallurgical solid waste treatment in steel mills. The weak part of the rotary hearth furnace for metallurgical solid waste treatment is mainly the high temperature section, and the life of the castable determines the length of the life of the rotary hearth furnace. The service environment of the castable in the high temperature section is bad, the atmosphere is complex, the high temperature gas and dust are highly corrosive, and accompanied by local over-temperature phenomenon, solve the problem of resistance damage caused by local overtemperature, and use non-oxide reinforced matrix to improve the corrosion resistance of castable. Metallurgical solid waste treatment rotary hearth furnace relies on the company's technical advantages in the field of industrial furnace, other supporting materials of rotary hearth furnace also have the advanced nature of the industry, the company's rich construction experience in the field of industrial furnace, the construction process of rotary hearth furnace to meet the harsh construction requirements of rotary hearth furnace.
After 7 years of exploration and development, the company has made remarkable achievements in the field of metallurgical solid waste treatment rotary hearth furnace. The company has obtained the general contracting business of the rotary hearth furnace transformation project of Tangshan Yanshan Iron and Steel Co., Ltd., and at the same time, the company and the design institute have cooperated to undertake the refractory supply business of the rotary hearth furnace, such: chongqing Sadie-Shougang Jingtang Zinc-Containing Solid Waste Disposal Project, Chongqing Sadie-Baosteel Iron-Containing Solid Waste Disposal Center Phase II Project, Chongqing Sadie-Xinyu Iron and Steel Co., Ltd. Dust and Mud Comprehensive Treatment Project, Chongqing Sadie-Zhongtian Iron and Steel Solid Waste Disposal Center Project, Baowu Group Environmental Resources-Lianfeng Turn Bottom Furnace.
The company seized the opportunity of rapid development of refractory materials in the field of environmental protection, and set a benchmark for the company with a series of metallurgical solid waste treatment stoves. The company shared the results of years of exploration and formulated them into industry standards, which played a positive role in promoting the technological progress of the industry, helped the development of metallurgical solid waste treatment field, and made a modest contribution to the development of national environmental protection.
