Refractory Gunning Machine
New Products From This Supplier
Key Features
1. Hot - state Repair Technology
This machine is specifically designed for converters refractory brick repair at high temperature. It can operate at temperatures up to 1,600°C, eliminating the need to cool down the converters and ladles. This allows for repair of refractory brick in converters during short production breaks, ensuring continuous operation and maximizing productivity.
2. Semi - dry Refractory Gunning System
Equipped with a semi - dry refractory gunning system, the machine combines precision and speed. It can deliver a dense and durable refractory coating, making it perfect for repairing areas prone to erosion, such as the walls of converters, slag lines, and the bottoms of ladles.
3. Flexible Operation and Precise Control
The refractory shooter nozzle on this machine offers adjustable spray angles and material flow rates. This ensures uniform coverage of the repair area and minimizes material waste. Moreover, the remote - controlled operation enhances safety by keeping operators away from high - temperature zones.
4. High - Temperature Resistant Structural Design
The machine is constructed with heat - resistant components that can withstand prolonged exposure to molten metal and slag. Its modular design allows for quick replacement of nozzles and hoses, enabling rapid deployment and reducing maintenance time.
Benefits
1. Improved Production Efficiency
By eliminating the need for cool - down periods, the machine can reduce repair time by over 50%, ensuring continuous production and significantly increasing overall efficiency.
2. Extended Furnace Life
Timely repair of the hot refractory lining reduces the frequency of major periodic overhauls, thereby lowering maintenance costs and extending the service life of converters and ladles.
3. Enhanced Safety
The fully remote - controlled operation minimizes operators' exposure to high - temperature environments, effectively avoiding the risk of burns and other safety hazards.
4. Reduced Material Loss
The semi - dry refractory gunning system improves the adhesion rate of the refractory material, reducing waste and optimizing material usage.
