What’s repairing technology of ladle gunning mix

Ladle gunning mix is a refractory material that is used to line the inner surface of steel ladles used for molten steel transfer in steelmaking plants. Over time, the ladle gunning mix can become damaged or worn out, and repair is necessary to maintain the integrity of the refractory material lining and ensure safe and efficient steel production. Here are the steps involved in repairing the technology of ladle gunning mix:

Inspection: The first step is to inspect the ladle lining to determine the extent of the damage or wear. This is typically done by visual inspection, but other methods such as ultrasonic testing may be used for more accurate results.

Preparation: Once the extent of the damage is determined, the area to be repaired must be prepared. This typically involves removing any loose or damaged material from the surface of the lining, and cleaning the area to ensure good adhesion of the new ladle gunning mix.

Mixing: The next step is to mix the gunning mix according to the manufacturer’s instructions. This typically involves adding water to the dry mix and mixing until a smooth and consistent mixture is obtained.

Application: Once the mix is ready, it can be applied to the prepared surface using a gunning machine. The mix is typically sprayed onto the surface under high pressure, and then tamped or compacted to ensure good adhesion.

Curing: After the ladle gunning mix is applied, it must be allowed to cure for a specified amount of time. This typically involves drying at ambient temperature or using a heat source to accelerate the curing process.

Inspection and Testing: Once the ladle gunning mix has cured, the repaired area must be inspected and tested to ensure it meets the required specifications for strength and durability. This typically involves visual inspection, as well as various testing methods such as ultrasonic testing or abrasion testing.

Overall, repairing the technology of ladle gunning mix involves careful inspection, preparation, mixing, application, curing, and testing to ensure a high-quality repair that meets the required specifications for safe and efficient steel production.
