Inject the slurry


In-furnace repair mortar is an unshaped refractory material used for lining repairs in thermal equipment such as blast furnaces. It is applied by injecting the slurry into cracks or damaged areas using a mud pump, effectively filling, sealing, and restoring the affected zones. This material is characterized by its excellent fluidity, allowing it to penetrate even tiny fissures, while also exhibiting strong adhesion to substrates like refractory bricks and castables. Additionally, it boasts superior resistance to high temperatures and corrosion. Commonly employed for repairing equipment such as blast furnaces, hot-blast stoves, and rotary kilns, this mortar helps extend equipment lifespan and significantly reduces downtime for furnace maintenance and inspections.
