RSG, supplies well blocks in a number of different compo-sitions to suit the best operating conditions of the steel ladle. Wellblocks are available in basic and alumina qualities to match the slag basicity. Blocks are either pressed or pre-cast depending on the composition. These shapes can be pre-fired if necessary to ensure optimum performance. These pieces are custom-designed for a specific ladle with attention to total life, free open performance and cost.

RSG, supplies nozzles in a number of different compositi-ons to best suit the operating conditions of the steel ladle. Nozzles are available in alumina qual-ities (with and without carbon additions, zirconia additions, and/or chrome additi-ons) to best resist the slag chemistry. Nozzles are either pressed or pre-cast depending on the composition. These shapes can be pre-fired if necessary to ensure optimum performance. These pieces are custom designed for a specific ladle with attention to total life, free open performance and cost.

RSG, supplies metallic parts and complete assemblies for all of the popular systems on the market. These pieces are CNC machined from high-quality steel castings or steel billets depending on the part. Metallics are machined to exacting tolerances while still offering substantial savings over OEM.

RSG, offers a wide range of slide gate plate refractories for various international systems including Flocon, Interstop (including LS Series), Vesuvius (including LV Series), Saflow and Sanac. 

RSG’s slide gate plate brick are available in a number of different chemistries and bond systems to best match the grades of steel and chemistries of the slag. All of the plate brick are machined to exacting tolerances, in some cases better than OEM specifications. RSG personnel look forward to working with the end user with the goals of lower cost, higher performance and greater reliability.

Depending on the requirements of the customers, these plates are exported in different qualities, namely Alumina Carbon, Alumina Spinnel Carbon, Magnesia Spinnel Carbon and Alumina Zirconia Carbon.

The Company also exports Inserts used for repairing old slide gate plates for re-use. Recently Zirconia insert plates have also been introduced as a new product by the Company.

RSG, supplies nozzles in a number of different composit-ions to best suit the operating conditions of the steel ladle. Nozzles are available in alumina qualities (with and without carbon additions, zirconia additions, and/or chrome additions) to best resist the slag chemistry. Nozzles are either pressed or pre-cast depending on the composition. These shapes can be pre-fired if necessary to ensure optimum performance.

RSG, offers ladle shrouds in both alumina-graphite and fused silica qualities. The alumina-graphite shrouds are isostatically pressed with zirconia wear bands and argon channels as necessary for the particular casting and cleanliness requirements of a shop. All AG shrouds are X-rayed for flaws and imperfections prior to shipment. The fused silica shrouds are designed primarily for cost savings. They are intended to supplement AG shrouds for shorter casting sequences, or as a cheaper alternative to AG for shops that run non-aggressive tundish practices.

Ladle to Tundish Shrouds are used to protect and control the flow of steel from the Ladle to the Tundish. Made of Alumina Carbon quality they can be used for both hot and cold starts. Ladle Shrouds are custom made to meet the specific use of each customer with options to provide for metal can, ceramic paper wrapping, porus insert etc.

RGS’s stopper rods are made from alumina-carbon in isostatic presses with zirconia inserts and/or magnesia tips as necessary for optimum performance. Argon channels are likewise available to suit a particular operation. Stopper rods are all X-rayed before shipment to eliminate flaws and cracks. Stopper rods can be supplied bare or with mounting hardware as required.

Stopper is used to control the flow of steel through the Tundish Nozzle. It is made of Magnesia Carbon or Alumina Carbon quality with special compositions at the tip and slag zone to suit customer requirements. Cross pin or screw fastening or gas purging facilities are provided as and when required.

RSG’s tundish nozzles are primarily zirconia, but cheaper ones can be made in pre-cast spinel shapes or pressed alumina as needed to provide lowest cost at desired performance levels. Pressed zirconia nozzles are available in different purities with and without flutes. Pressed nozzles deliver minimal bore variation and optimal density for long life and the least wear.

Company supplies a very wide range of Tundish Nozzles used for controlling the flow of steel from the Tundish to the Continuous Casting equipment including:

1.Zirconia/ Zircon Nozzles – Offered in 65% to 95% Zirconia for single to multiple casting application with a teeming time of up to 40 hours.

2.Isostatically Pressed Nozzles – made in Alumina Carbon quality for large steel plants

RSG’s SENs are isostatically pressed from alumina-graphite with zirconia inserts and magnesia seats as required. Argon channels are available too. These pieces are 100% X-ray tested for flaws and cracks prior to shipment. These SENs are engineered to provide maximum life at minimal cost.

The Submerged Entry Nozzle (SEN) and Submerged Entry Shroud (SES) protect the steel flow from the Tundish to the mould. Submerged Entry Nozzle is fixed inside the Tundish and also functions as a Tundish Nozzle.Submerged Entry Shroud on the other hand is fitted from the outside on the Tundish Nozzle. The body is made of Alumina Carbon quality while the seat and slag zone are made of different qualities as per customer requirements including Zirconiz-Carbon and Magnesia Carbon quality. The SEN and the SES are protected from the outside with a ceramic paper lining.

We can provide a wide variety of products to suit your needs.
