In foundries, refractory gunning machines are key equipment used to spray refractory materials onto the inner wall of high-temperature equipment to form a protective layer. Its specific application scenarios include:
1. Repair and maintenance of furnace linings
Blast furnaces, electric furnaces, induction furnaces, etc.: In high-temperature environments, furnace linings are susceptible to erosion and peeling. Gunning machines can quickly and evenly spray refractory materials, repair damaged parts, extend the life of furnace linings, and reduce downtime for maintenance.
Converters and refining furnaces: Used to repair easily worn areas such as furnace mouths and furnace bottoms to ensure the sealing and safety of the furnace body.
2. Protection of the pouring system
Ladles and tundishes: Gunning machines can repair the lining of the pouring system to prevent metal liquid leakage and improve pouring quality.
Flow troughs and nozzles: During the casting process, flow troughs and nozzles are susceptible to erosion by metal liquid. Gunning machines can quickly repair them and reduce metal liquid pollution.
3. Melting equipment maintenance
Melting furnace, insulation furnace: The gunning machine can be used for regular maintenance of the furnace lining to prevent the furnace lining from cracking and falling off, and ensure the stability and safety of the smelting process.
Heat treatment furnace: During the heat treatment process, the furnace lining is easily affected by thermal shock. The gunning machine can repair it in time to extend the service life of the furnace body.
4. Special process requirements
Centrifugal casting: During the centrifugal casting process, the inner wall of the mold needs to have high wear resistance and high temperature resistance. The gunning machine can spray special refractory materials to meet the process requirements.
Vacuum casting: Under vacuum environment, the furnace lining needs to have good sealing performance. The gunning machine can ensure the sealing performance of the furnace lining after repair.
5. Environmental protection and energy saving
Waste gas treatment equipment: The gunning machine can be used to repair the refractory layer in the waste gas treatment equipment, prevent waste gas leakage, and reduce environmental pollution.
Energy-saving transformation: Repair the furnace lining with a gunning machine to reduce heat loss and improve energy efficiency.
6. New lining construction
New furnace body: When building a new furnace body, the gunning machine can be used to spray refractory materials quickly and evenly to form the initial lining and improve construction efficiency.

Technical advantages of refractory gunning machine for foundry factory:
High efficiency: The gunning machine can achieve continuous and large-area spraying, significantly shortening the maintenance time.
Uniformity: By precisely controlling the spraying pressure and flow rate, the refractory materials are evenly distributed and the lining quality is improved.
Flexibility: Suitable for equipment of different shapes and sizes to meet diverse needs.

Other application cases of refractory gunning machine:
Steel foundry: used for refractory layer repair of blast furnaces, converters, and pouring systems.
Non-ferrous metal foundry: used for lining maintenance of metal smelting equipment such as aluminum and copper.
Refractory material manufacturers: used to test and verify the performance of new refractory materials.
