This reduces blast furnaces’ operational risks and ensures stable production plans; directly improving furnace productivity extending furnace lining service life.
Trough operations typically see refractory linings exposed to constant thermal cycling and oxidizing environments, resulting in standard Al2O3-SiC-SiO2-C castables becoming damaged.
This leads to a notable reduction in the trough campaign life; resulting in the need for emergency repairs, increased refractory unit consumption and unplanned stoppages.
Saint-Gobain Performance Ceramics & Refractories’ unique and innovative castable technology ensures a reliable and risk-free campaign while reducing the number of hours spent on trough repairs.
Why is oxidation resistance important in a trough and runner material?
Castable components as SiC and C are highly susceptible to oxidation. This results in the production of SiO2 and CO/CO2, which can impact material properties, resulting in increased porosity, loss of texture and mechanical resistance.
Oxidation poses a particular risk when this occurs close to backup linings, ultimately leading to increased wear speed and refractory consumption.
