Leader in Iranian hydraulic cylinder since 1971

Iron & Steel Industry Cylinders
The iron and steel industry utilizes hydraulic jacks in nearly all of its processes. In recent years, these systems have evolved into electro-hydraulic systems through the integration of linear scale applications and PLCs. Blast furnaces, steel plants, continuous casting facilities, hot strip rolling mills, wire rod and rebar production plants, and cold rolling mills have all become fully hydraulic. Raman Shams has been working on a project basis for many years and also offers a variety of products in different sizes and configurations in this sector. Additionally, the company provides maintenance and repair services to domestic factories. Moreover, Raman Shams collaborates with international companies involved in setting up such facilities, contributing to both the design and production of related products.

AGC (Automatic Gauge Control) - Roll force cylinders Rolling mill cylinders operate in harsh steel plant environments for sheet and rebar production. Smooth, efficient performance alongside reliability and extended lifespan are critical for these cylinders. Metallurgical Equipment Cylinders Metallurgical equipment serves as essential production tools in metallurgical plants, where the proper functioning of hydraulic cylinders is critical for normal operations. Hydraulic cylinders are heavily utilized and prone to wear, meaning high-quality cylinders indirectly extend the service life of metallurgical machinery. With over 20 years of expertise, we specialize in manufacturing metallurgical equipment cylinders and can customize hydraulic cylinders to meet your specific operational requirements. Furnace cylinders Steel plant furnaces require hydraulic cylinders for tilting operations, moving, and closing doors and flaps. These cylinders are often exposed to high temperatures. It is essential for furnace tilting cylinders to operate with precise, slip-free linear motion. Ladle turret Cylinders Ladle turret cylinders used for molten steel handling demand extreme reliability and safety. These cylinders must also withstand high ambient temperatures. Raman Shams' ladle turret cylinders have proven their reliability over decades, with custom-engineered designs available in diverse sizes and configurations. Mandrel expansion Cylinders Mandrel expansion cylinders rotate and thus require a flange-mounted rotary hydraulic distributor at the cylinder base to supply oil. Both the chuck and rotary distributor must deliver reliable performance across variable rotation speeds, while clamping pressure in the cylinder must remain consistent throughout the steel sheet twisting process. Work roll change Cylinders Roll changing cylinders are used to extract worn roll assemblies from the mill housing and install new roll sets. Roll changes depend on factors like roll wear levels, the number of slabs produced, or changes to the steel grade being rolled. While the cylinder is not directly involved in the milling process, its continuous availability and reliability are critical to ensure the shortest roll change time.
