Abstract The production method of baking-free type Al2O3-SiC-C ramming mass for iron tap channel of iron-smelting blast furnace adopts a new type composite combination system, including thermosetting phenolic resin organic anchoring agent and ceramic anchoring agent, can make it do not produce aqueous vapour in the course of usage, and can give quick agglutinating property to ramming mass so as to ensure that after the iron tap channel is constructed with ramming mass, it has no need of baking, and can be directly used for tapping, and can produce higher high-temp. strength after use, so that it raises the service life of iron tape channel, reduces refractory consumption and production cost, reduces labour strength and improves working environment.
