Product introduction:
Converter Gunning Material uses sintered magnesia and other alkaline composite materials as the main raw materials. Reasonable particle grading design makes Converter Gunning Material have good sintering performance and anti-scouring performance. It has small rebound rate and high bonding rate during construction and is easy to operate. Converter Gunning Material is suitable for hot repair of converter slag line, ear shaft and other parts.

Product advantages:
1. Using our Converter Refractories can reduce production costs, effectively repair the furnace lining and extend its service life, Refractories can reduce the need for frequent replacement of the furnace lining, and reduce overall maintenance costs.
2. Our Converter Refractories can save energy and protect the environment, reduce heat loss of the furnace lining, improve energy efficiency, reduce energy consumption, and at the same time Refractories can reduce waste and environmental pollution, meeting environmental protection standards.
3. Our Converter Refractories have strong adhesion, Refractories can achieve uniform coverage, ensure consistent thickness of the repair layer, and quickly repair. Converter Refractories effectively prevent smelting slag from corroding and eroding the furnace lining, and extend the service life of the furnace lining.
Product Categories:
According to the state of the material used for gunning and the spraying method, Converter Refractories can be divided into three types:
1. Wet gunning, which can generally only repair thin layers.
2. Dry gunning (also known as semi-dry gunning), which can repair thicker layers, is the most widely used.
3. Flame gunning can obtain a dense gunning layer with high bonding strength and strong anti-erosion and anti-scouring properties.
According to the state of the sprayed material on the sprayed working surface, Converter Refractories can be divided into:
1. Molten material spraying method, which is divided into flame spraying, plasma spraying, and slag splashing furnace protection method.
2. Cold material spraying method, which is divided into mud spraying, dry spraying, semi-wet spraying (or tidal spraying), mixed spraying, and wet spraying.
The particle size composition and limit particle size of Converter Refractories should be determined according to the structure of the gunning machine, the thickness of the gunning layer, and different gunning methods. Improper particle size selection or unreasonable particle grading has a great impact on the adhesion of the gunning material and the density of the gunning layer.
