Refractory gunning machine for furnaces for melting Cu
Application cases of refractory gunning machine for furnaces for melting Cu: Copper smelting plant: used for lining repair of reverberatory furnace, tilting furnace, anode furnace and other equipment. Recycled copper smelting: In the process of scrap copper recovery smelting, the gunning machine can quickly repair the furnace lining and adapt to frequent furnace switching.
Refractory gunning machines are equipment used to repair the lining of industrial furnaces, especially smelting furnaces. These machines are particularly important when it comes to copper (Cu) smelting, because during the copper smelting process, the furnace lining will be affected by high temperatures and chemical erosion, resulting in loss or damage. In order to extend the service life of the furnace and maintain its efficient operation, regular repairs with refractory materials are necessary.
Technical advantages of refractory gunning machine for furnaces for melting Cu:
Efficiency: Gunning machines can achieve large-area and fast spraying, significantly shortening the shutdown and maintenance time.
Uniformity: By precisely controlling the spraying pressure and flow rate, the refractory material is evenly distributed and the repair quality is improved.
Flexibility: It is suitable for smelting equipment of different shapes and sizes to meet diverse needs.
The following are its specific application scenarios:
1. Repair and maintenance of furnace lining
Lining of copper smelting furnace: During the copper smelting process, the furnace lining is subjected to high temperature and chemical erosion for a long time, which is prone to cracks, peeling or wear. Refractory gunning machines can quickly spray refractory materials (such as high-alumina, corundum or silicon carbide gunning materials) onto damaged parts to form a dense protective layer and extend the life of the furnace lining.
Furnace roof and furnace door: The furnace roof and furnace door are the main areas where high-temperature gas and melt splash. Gunning machines can efficiently repair the refractory layer in these parts to prevent fire leakage and heat loss.
2. Melting process protection
Emergency repair: During the smelting process, if local refractory materials are damaged due to improper operation or equipment failure, the gunning machine can immediately repair them on site to avoid shutdown losses.
Thin layer gunning: By adjusting the particle size and spraying pressure of the gunning material, thin layers (such as 10-30mm) can be quickly gunned to reduce the impact on the smelting process.
3. Reinforcement of special parts
Edge of the molten pool: The edge of the molten pool of the copper smelting furnace is easily eroded by the melt. The gunning machine can strengthen the refractory layer in this area to prevent melt leakage.
Copper outlet and flow channel: Copper outlet and flow channel are the key channels for the flow of high-temperature copper liquid. The gunning machine can repair the refractory materials in these parts to ensure the smooth flow of copper liquid and reduce the risk of blockage.
4. Energy saving and environmental protection
Reducing heat loss: By repairing the refractory layer of the furnace lining and furnace roof, heat loss can be reduced, smelting efficiency can be improved, and energy consumption can be reduced.
Reducing dust emissions: The refractory gunning machine adopts wet spraying or semi-dry spraying process, which can effectively reduce dust flying and improve the working environment.
5. New lining construction assistance
Rapid prototyping: When building a new copper smelting furnace, the gunning machine can be used to assist the lining construction, quickly form the initial refractory layer, and shorten the construction period.
Complex part processing: For special-shaped structures in the furnace lining or parts that are difficult to construct manually, the gunning machine can achieve uniform and dense spraying.
6. Applicable refractory materials
High-aluminum gunning material: Suitable for lining repair of general copper smelting furnaces.
Corundum gunning material: suitable for high temperature and highly corrosive environments, such as copper refining furnaces.
Silicon carbide gunning material: suitable for high wear areas, such as copper outlets and chutes.
