3. Overall tamping method: Do not use charcoal bricks, cast the entire furnace with cold soup.

1. Wide seam method, the brick seam is first eroded and consumed by the iron wire, and the iron wire penetrates under the carbon brick, gradually igniting the carbon brick and causing the furnace lining to fail.

2. The so-called seamless method actually does not have real seams. Hot water flows along the brick joints and reaches the bottom of the charcoal brick, gradually causing the entire lining to malfunction and become unusable.

3. The overall compaction method is that carbon bricks do not undergo high-pressure compression and vacuum baking processes, and their performance is much lower than that of pre baked carbon bricks. Therefore, their service life is short, generally not exceeding one year, but this method is inexpensive and has a short construction period. Through years of production practice, the manufacturer of the mineral heat furnace compared the differences between these three methods. Based on the seamless method of the original carbon brick, the carbon brick was reprocessed into a circular groove and concave structure, cleverly utilizing the characteristics of its own carbon material to develop a new method of connecting carbon bricks to each other, connecting multiple layers and between layers. Cut off the gaps between metal infiltration and lateral infiltration, and connect the carbon bricks of the entire furnace lining together.
