Hot Patching EAF Gunning Mix
The Hot Patching EAF Gunning Mix is a refractory spray material specially used for electric arc furnaces, suitable for maintenance and repair under high-temperature conditions. Its main function is to repair the refractory lining in key areas of the furnace to extend the service life of the furnace lining and improve production efficiency.
Ladle Gunning Mix
The Ladle Gunning Mix is a high-performance refractory material designed for the steel smelting industry and is widely used in the repair and maintenance of ladle linings in steel plants. It is usually evenly coated on the surface of the ladle lining by spraying to resist high temperature, strong corrosion, and mechanical impact.

Benefits of Using Gunning Mix
Fast Installation
Repairs can be completed quickly, minimizing downtime and production loss.
01
Good Adhesion
The mix bonds tightly to old refractory surfaces, creating a dense, durable repair layer.
02
Flexible Thickness
Layers can be applied as thin touch-ups or thicker build-ups depending on damage severity.
03
Reduced Labor Costs
Spraying is faster and less labor-intensive than bricklaying or casting.
04
Versatile Application
Suitable for hot or cold repairs, depending on the product type.
05
Storage & Handling: The filling material must be well protected against dampness or moisture. Do not use if agglomeration appears.
Shelf Life: 6 Months.
Usage of Gunning Mix
Initial Lining
Gunning mixes are used for the initial lining of EAFs, providing a strong and durable refractory layer that can withstand the intense conditions of the furnace.
Refractory Repairs
During routine maintenance or after a campaign, gunning mixes are applied to repair and refurbish worn or damaged sections of the furnace lining, restoring its performance and extending its lifespan.
Maintenance
Regular application of gunning mixes helps to maintain the integrity of the furnace lining, addressing wear and tear and ensuring continued efficient operation.
Specialized Applications
Gunning mixes can be formulated for specific applications, such as high-carbon steel production or advanced metallurgical processes, providing tailored solutions for diverse EAF requirements.
