The Differences Between Stable Furnace and Tilting Furnace Brown Fused Alumina

First, the smelting method and machine of stable furnace and tilting furnace.

Second, the chemical content of Sio2 is different. Stable furnace brown fused alumina has 1.5%max Sio2 while tilting furnace brown fused alumina is characteristic with 1.0%max Sio2 content. The Sio2 chemical content is the most direct method to distinguish whether stable furnace or tilting furnace.

Stable furnace brown fused alumina is the intermittent production with the low degree of mechanization, low heat utilization, high power consumption, and every time before smelting the furnace need repairing, but the investment of stable furnace is less, only need simple and easy operated equipment. The stable furnace is widely used in some fused alumina plant. Compared with the stable furnace, the tilting furnace can continuous production. It has a high degree of mechanization, low power consumption, high production efficiency, no need to repair the furnace every time, but a larger investment is currently the most commonly used a corundum smelting method.

And the technical indicators of the two processes are listed below.

In addition to the above differences, the quality of brown fused alumina smelt in the stable and tilting furnace is different. The crystal size of tilting furnace brown fused alumina is smaller and more sharp that stable furnace, while the stable furnace brown fused alumina is harder than tilting furnace.
