open fire furnace
Beijing JJRS Technology Development Co., Ltd. registered in national high tech park-Beijing Economic and Technological Development Zone, is high-tech enterprise specialized in the complete set of metallurgical equipments, intensive processing of steel strip and metal surface coating engineering project, with the integration of mechanism, optics, electric and hydraulic pressure.
JJRS supplies custom-tailored hot annealing and pickling lines with or without inline equipment, such as rolling mills( so called DRAP or WRAP lines). We have many references in China and abroad, with technological know-how, especially for greenfield producers with effluent - free lines, heat recovery from furnace.
JJRS is professional on turn-key projects, from general planning, designing, to manufacturing, installing, commissioning and servicing. Besides, our business also covers single equipment’s designing, manufacturing and installing, as well as electric transmission, control system and spare parts. All basing on these supporting businesses, we mark out a developing strategy that taking metal strip intensive processing and color coating production lines as main, and the associated industry products as supplement.
JJRS assembles excellent technology research team, high qualified management personnel, perfect management system and powerful engineering design and complete project capability. As an integrated solution provider, we are willing to provide iron and steel enterprises of all over the world with highest quality products and services, from general engineering contracting, integrated production lines, to single equipment, even components and spare parts.
Annealing treatment is one of the important procedures during steel strip cold rolling production procedure. The annealing is purposed to remove the inner rolling stress of steel strips, improve mechanical property and clean the surface of steel strips. Annealing equipments can be categorized into bell type annealing furnace and continuous annealing furnace. Our company usually undertakes continuous annealing furnace projects.
Continuous Annealing Furnace Features
