Rosewool's Mission
Focus on refractory, insulation and energy-saving, devote to safety, comfortability and sustainability, achieve CSV mission
Rosewool Insulation Refractory Co., Ltd. was founded in 1982 and is located in Zhengzhou, Henan Province, China. It is a comprehensive company that integrates production, sales, and construction. It is a recommended supplier of insulation and thermal insulation materials for China's Ministry of Electric Power, Ministry of Metallurgical Industry, Ministry of Cement Industry, and National Petroleum and Chemical Industry. It is a pilot base of China Academy of Building Materials Science and Tianjin Institute of Chemical Technology.
1982
In 1982, the company was established in Xinmi City, Henan Province. This location is about 30 kilometers from the middle section of Zhengzhou-Linshi Road, enjoying unique geographical advantages. It is rich in mineral resources and has a complex network of transportation links, providing a solid foundation for the company's subsequent development.
1990
1982 - 1990: The technological foundation period. We introduced the production technology of ceramic fibers and developed processes such as the melt spinning method.
1992
The team participated in the domestication project of refractory materials for the second phase of Baosteel's construction, and developed the first generation of 1260℃ standard ceramic fiber blankets.
1995
Achieve mass production of ceramic fiber blankets (with a slag particle rate of less than 18%, meeting the international Class II product standards).
1999
After the state-owned enterprise was restructured, the team established the Gongyi Joint Fireproofing Studio to serve small and medium-sized kiln furnaces.
2002
Developed a pre-compression modular installation process and obtained a utility model patent.
2005
The first all-electric melting furnace production line has been completed, with an annual production capacity of 120 tons.
2008
Established a 1,000-square-meter factory for innovative ceramic fiber products in Gongyi, Henan Province ("The Capital of Refractory Materials in China"), specializing in the production of ceramic fiber blankets.
2009
International layout: Obtained ASTM C892 (American standard) and BS 3958 (British standard) certifications. The first export order was to Vietnam (for industrial furnace lining project).
2011
The company has reached an important development stage and has resolutely invested over ten million yuan to build an automated production line for molding materials with modern standards. The completion of this production line is of great significance, directly driving a leapfrog growth in the company's production scale, from the original annual output of 40,000 tons to a staggering 90,000 tons. The increase in production capacity has greatly enhanced the company's competitiveness in the market and created conditions for meeting the needs of more customers. The Zhengzhou Tianzhong Thermal Insulation Materials Co., Ltd. was established to handle the import and export business of thermal insulation materials, refractory materials, and related technologies.
2012
Collaborated with research institutions such as Luoyang Refractory Materials Research Institute, Beijing University of Science and Technology, and China Building Materials Research Institute, and began to conduct more types of refractory material research.
2014
Technical upgrade and certification breakthrough: Obtained ISO 9001 quality management system certification and independently developed the "low slag ball content formula" (slag ball rate ≤ 10%, superior to the national standard by 15%).
2016
The asbestos-free high-temperature resistant calcium silicate products have passed the inspection of the National Quality Supervision and Inspection Center for Fire-resistant Materials. Their performance exceeds the Japanese industrial standards.
2019
Won the bid for the insulation project of the Saudi PETROLINE oil pipeline.
2020
Established Henan Jinnaite Energy Saving Technology Co., Ltd., to carry out services, development, consultation, communication, transfer, promotion, research and development of new materials, manufacturing of insulation and soundproof materials, and sales of insulation and soundproof materials, etc.
2021
Four 30-cubic-meter reaction tanks, two 1,000-ton hydraulic presses and eight 60-meter tunnel-type drying kilns have been constructed. The annual production capacity of calcium silicate products is 40,000 cubic meters, that of aluminum silicate products is 80,000 cubic meters, and that of nano-insulation products is 80,000 cubic meters. The products are exported to more than 20 countries including the United States, Southeast Asia, Africa, and Europe, covering industries such as power, metallurgy, cement, glass, and ceramics.
2023
The company has applied for a patent for "Dust Removal Equipment for the High-Temperature Resistant Silica Calcium Board Production Line" (Patent Number: 202323626539.1)
