(1) The feeding material has good spreadability at the waste heat temperature (800-1200 ℃) of the converter lining.
(2) Feeding material can be solidified quickly after spreading.
(3) The solidified feeding material has good adhesion to the original furnace lining.
(4) The feeding material should have good erosion resistance.
The feeding materials are based on magnesia and dolomite sand, and the process performance is mainly determined by the binder. Commonly used binders are asphalt, resin or a mixture of the two.
