How To Choose A Ceramic Mug?

In comparison to plastic cups, ceramic cups emit fewer harmful gases and substances. Experts suggest that prolonged use of plastic cups might elevate the risk of cancer.

Ceramic cups are inherently safe and non-toxic, eliminating the risk of ingesting harmful metals that could occur with extended use of metal cups.

The design of ceramic cups ensures that hot metal does not come into direct contact with the carbon brick, thus minimizing the penetration and erosion caused by hot metal and alkaline substances on the carbon brick structure. Advanced ceramic materials, such as mullite and brown corundum, exhibit low thermal conductivity, superior erosion resistance, and corrosion resistance, which contribute to mitigating the embrittlement layer of large carbon bricks.

By elevating the temperature of molten iron and decreasing heat loss, ceramic cups utilize a low thermal conductivity material as an intermediate layer, effectively reducing heat dissipation through the furnace bottom and walls, ensuring that the molten iron remains at a high temperature, and creating favorable energy-saving conditions for subsequent converter operations.

The thermal insulation properties of ceramic cups streamline the rewinding process, minimize heat loss during blast furnace downtime, and facilitate the swift resumption of production.

Ceramic cups also prevent hot metal leakage, as the solidification line of hot metal is near the inner surface of the furnace lining, and the slight positive residual expansion of the refractory material narrows brick joints, restricting the penetration of hot metal and substantially reducing the risk of furnace burn-through.
