Group Profile
Building the "Great Wall of China" in the refractory materials industry
Company Founded in
Production Workshop
Jinzhou Changcheng Technology Group Co., Ltd. has four subsidiaries: Jinzhou Great Wall Refractory Materials Co., Ltd., Kunming Great Wall Refractory Materials Co., Ltd., Jinzhou Great Wall Metallurgy Technology Co., Ltd., and Yunnan Changcheng Technology Co., Ltd. It is a comprehensive high-tech enterprise with independent intellectual property rights. The main products are SA spinel refractory materials.
The company's products have been widely and successfully applied in the non-ferrous metallurgy, ferrous metallurgy, building materials, petrochemical, power, hazardous waste and solid waste treatment industries at home and abroad, and have been exported in batches to countries and regions such as South Africa, Peru, Congo (Kinshasa), Thailand, India, Iran, Indonesia, and Malaysia.
SA Great Wall series spinel refractory materials, according to the different damage mechanisms of refractory materials in different parts of metallurgical equipment, and the differences in the type and composition of the melt, through adjusting the composition of the refractory materials and various physicochemical indicators, etc., produce a unique series of products with chemical corrosion resistance, high-temperature fluid erosion resistance, and strong thermal shock resistance, which has several times the service life compared to other conventional refractory materials.
Our SA spinel products have been used in various kilns for more than 20 years. Based on a deep understanding of the production process characteristics and smelting mechanisms of various kilns, a complete SA technical system has been formed, which can provide users with a comprehensive solution based on refractory materials, greatly improving product performance and the degree of matching with working conditions, highlighting the personalization and functionality of SA Great Wall series products, and making the service life of metallurgical equipment reach the world's advanced level. In 2023, the company was awarded the title of Manufacturing Champion Enterprise by the organizing committee of the 8th China Manufacturing Strong Country Forum.
Application examples: Top-blown equipment from manufacturers such as Tongling, Anhui and Daye, Hubei, has been used continuously for 4 years without water jacket protection, breaking previous records.
