Design of AOD Furnace Bottom
There are two types of AOD furnace bottom shape to choose: Dish and flat base.
Flat base furnace bottom is easy to be constructed, and it needs less firebrick types than dish furnace bottom, so the flat base furnace bottom is very widely used in America.
Dish furnace bottom needs more types of firebrick than flat base furnace, and it costs more time to be made than the flat base one, while it has two imporatnt advantages as follows.
1. The dish furnace bottom is designed according to furnace casing size and spherical radius of furnace bottom shell, thus finally improving the quality of ton loading by increasing the furnace bottom volume.
2. The structure of dish furnace bottom will keep the original shape even after most of the bottom firebricks have been worn down.
