Can High-aluminum Refractory Balls Pump Water Into The Sphere?

In principle, high-aluminum refractory balls cannot be watered, because watering will reduce the strength of the refractory balls. Reducing the strength will naturally affect the service life. However, the high-aluminum refractory balls currently shipped from the factory are slightly sprinkled, because the refractory balls just out of the kiln must be packed in ton bags for delivery or storage. However, after the refractory balls are sintered at high temperature since the tunnel kiln for burning refractory balls is shorter than the kiln for burning high-alumina bricks, the refractory balls will be hot when they first come out of the kiln, and the packaging will burn out the outer packaging, so there will be a slight sprinkle of water. This makes it easy to load large bags.

However, it is not allowed if the water pipe directly sprays water onto the high-aluminum refractory sphere. This will reduce the strength of the refractory sphere and may cause cracking and affect the service life. To increase the weight, some unscrupulous salesmen increase the weight of the refractory balls by sprinkling water for profit so that the refractory balls cannot be thrown underground and cause breakage, so special attention should be paid to this medicine.

High-aluminum refractory balls were originally made by hand, with low strength and low productivity. Later, it was changed to a 20-50-ton briquetting machine for pressing. The machine-made refractory balls have high strength and long service life. However water cannot be injected, and water injection also reduces the strength. Later, it was changed to a multi-ball briquetting machine, that is, the press presses out 12 refractory balls at the same time. Not only is the production efficiency high but the density and strength of the refractory balls are better than those of early manual or single balls. Pressure refractory ball strength.

Early high-aluminum refractory balls were fired in inverted smoke kilns or non-cavity kilns. Later, due to environmental reasons, it was changed to tunnel kiln firing. The tunnel kiln has a large output and can be produced continuously, but the fuel cost increases. Fire-resistant balls are prone to high temperatures and are easy to burn during packaging. They can be slightly cooled by drinking without affecting the intensity of use. However, it is not good to draw water, which will seriously affect the quality of the fire-resistant ball.
