Avoid Costly Refractory Repairs with Proper Maintenance
Oct 12 2018 · As the old saying goes "An ounce of prevention is worth a pound of cure." This is certainly true when it comes to your refractories. Manufacturers around the world rely on refractories to safeguard their multi-million dollar industrial-grade boilers incinerators and furnaces from thermal damage and corrosion brought on by operating temperatures that can reach 3000°F (1650°C).
