Refractory gunning machine and refractory pan mixer for sale
Gaode Equipment is a professional refractory equipment manufacturer and supplier from China. We can provide you with electric, pneumatic and diesel-powered refractory shotcrete machines of various displacements and refractory mixers with mixing capacities of 100kg, 200kg, 250kg, 300kg, 500kg, 750kg, 800kg and 1000kg. They are widely used in the construction and preparation of high-temperature industrial refractory materials.
While refractory gunning machines and refractory pan mixers differ in their functions, they work closely together in the field of refractory materials, serving the construction, maintenance, and repair of industrial equipment requiring high-temperature operation.
Their common applications are primarily concentrated in the following key industrial sectors:
1. Iron and Steel Industry:
Blast Furnaces: This is the primary application. The mixer mixes the gunning mix used to repair the furnace lining, while the gunning machine sprays the mixed wet or dry mix at high speed onto eroded or damaged areas of the blast furnace lining for hot or cold repairs.
Converter Furnaces and Electric Arc Furnaces (BOFs and EAFs): During lining maintenance, the mixer prepares the gunning mix, while the gunning machine repairs vulnerable areas such as the furnace mouth, trunnions, and slag line, extending the life of the lining.
Ladles: The lining of the ladles used to transport molten steel also requires regular maintenance. Gunning technology allows for rapid repairs to the working layer, while the mixer prepares the necessary gunning mix.
Torpedo Ladles/Pots: Used to transport molten iron, their linings are susceptible to wear and tear from high temperatures and the erosion of molten iron. Gunning is a common maintenance method, with agitators and gunning machines working in tandem during this process.
2. Non-ferrous Metal Smelting:
Smelting furnaces for copper, lead, and zinc also involve high-temperature melts, which can corrode the linings. Gunning is used to repair the linings of reverberatory furnaces, flash furnaces, and converters, with agitators and gunning machines being key equipment for this process.
3. Glass Industry:
Glass Melting Furnaces: Glass melting furnaces operate at high temperatures for extended periods, and their linings are subject to corrosion from molten glass and volatiles. Gunning allows for in-process hot repairs of critical areas, such as hot spots and the liquid level, minimizing downtime. Agitators are used to prepare specialized gunning mixes suitable for glass furnaces.
4. Cement Industry:
Rotary Kilns: Refractory bricks in areas such as the firing zone and transition zone of a rotary cement kiln are subject to wear due to high temperatures and material erosion. Gunning machines can repair these areas, while mixers are responsible for mixing the refractory material for the gunning process.
Refractory gunning machines and refractory pan mixers are commonly used in all high-temperature industrial equipment requiring the use of monolithic refractory materials (particularly gunning mix) for lining, maintenance, and repair. They typically work together as a system:
The refractory castable pan mixer uniformly mixes refractory aggregate, powder, binder, and water (or liquid binder) to produce a high-quality, lump-free gunning slurry.
The refractory gunning machine sprays the mixture produced by the mixer onto the target working surface at high speed using compressed air or a pumping system, forming a dense, firmly adhered refractory layer.
Therefore, they jointly serve the construction and maintenance of thermal equipment such as blast furnaces, converters, electric furnaces, ladles, melting furnaces, rotary kilns, etc. in the steel, non-ferrous metals, glass, cement and other industries. Their core purpose is to extend equipment life, improve production efficiency, reduce maintenance costs and ensure production safety.
