Saint-Gobain's dry vibration, ramming and castable cements are used extensively with outstanding success in non-ferrous foundries. High-quality refractory materials are designed to deliver extremely efficient performance over the life of your campaign.
These materials have been engineered for cost-effective use in channel and coreless furnaces and inductors, as well as spouts, ladles, launders and tundishes. Saint-Gobain insulating castables also are available for covers.
Norton Dry Vibrated Cements (DVCs) provide quick turnaround and low relining costs due to shorter installation and firing times. They can be vibrated in successive layers with a Bosch vibrator or in a single run, thanks to form/internal vibrators. Interrupted installation has no detrimental effect and excess inventories can be stored for a long time. The DVC acts as a barrier against the penetration of metal fins and makes it easier to remove the crucible at the end of the campaign.
In addition to more than 100 years of experience in the development and production of refractory materials, Saint-Gobain understands the needs of our customers. We make our recommendation based on each foundry’s operation.
Saint-Gobain also manufactures a large range of castables, ramming and patching cements for use in almost all areas of iron and steel making furnaces, including, but not limited -- crucible, coil, topping, spout, inductor -- and we provide repair materials.
We understand you want maximum heats. That’s why Saint-Gobain materials offer the campaign longevity you require. Unlike our competitors, we only work with high-quality, pure raw materials that are engineered to achieve maximum performance. High density, low porosity and high purity result in low reactivity to protect coils in even the harshest conditions.
Furnace OEMs, along with other worldwide customers, are especially appreciating our consistent quality and material performance.
Especially with foundry in non-ferrous applications, the impact of refractories on the operations and product quality is crucial.
That’s why Saint-Gobain is providing specially-designed refractory products for each metal to get maximum performance, taking into account specific refractory-metal interaction (like wetting of refractory by aluminium).
The available product range is as wide as the operating temperature range and metal choice so that customers will find products based on aluminina, silica, magnesia or silicon carbide for hot face lining for production of aluminum, copper, zinc, brass or coating pot applications or others.
Furnace OEMs and a long list of worldwide acting customers are especially appreciating our constant product quality and material performance.
Saint-Gobain also supplies Norflow® Seflow castables for ferrous and non-ferrous applications providing superior installation comfort and speed by keeping exceptional hot temperature properties.
Channel furnaces can have various shapes and geometries (rectangular or cylindrical upper case, single or double loop inductor). Their sizes can also vary significantly. Every operation is different. That’s why Saint-Gobain engineers make recommendations based on each foundry’s specific furnace operation.
Channel furnaces always comprise three main areas — inductor, throats and upper case — submitted to various stresses. Saint-Gobain will select and supply high-grade refractory materials to resist slag line corrosion and inductor clogging to provide the most efficient and durable furnace operation.
For the lining of the upper case, Saint-Gobain also provides a large range of DVCs and castables as required by your operating conditions and specifications.
Coreless induction furnaces are one of the most used furnace types in steel and alloy production known for its flexibility and handling advantages.
The wide range of feedstock, product and operating conditions and its combination makes it necessary to provide a refractory material choice suitable to fit best with customer request. That’s why Saint-Gobain is providing products specially developed for each of the different factors impacting product quality, e.g. furnace size, melting temperature, feedback quality and type as well as daily operation planning.
Moreover, each zone of a coreless induction furnace requires refractories that are specially developed to show maximum performance in its area, and Saint-Gobain is able to supply such high-grade refractories for coil lining, main lining, topping and spout area. Castables, DVC, ramming mixes or patching products are available.
The use of the complete Saint-Gobain product range in the coreless induction furnace will also help to improve energy balance in production and consequently reduce overall cost.
