bake free ramming mixes for trough of blast furnace

1,high density 2,good thermal stability 3,low melt loss rate

In order to meet the high yield and high efficiency of modern blast furnace, improving blast furnace trough ramming material for durability, our company in the common blast furnace tapping ditch Ramming expected on the basis of blast furnace trough, developed by AL3O3 - SiC - C for baking ramming material. Period characterized by ramming forming without baking and direct tapping, can save the furnace repair time and channel, slag corrosion resistance, oxidation resistance performance is good, when in use, no shrinkage, no crack, the surface is smooth and not sticky slag iron can immediately, ramming through tapping, widely used in, the small trough of blast furnace site

Construction descriptions:

Before construction of the trough processing clean, removing iron residue and residue, the groove cooling slightly after laying, ditch bottom paving thickness of about 350mm, laying paving thickness should be determined according to the blast furnace, for general 150mm-200mm thickness, material paved with ramming machine repeatedly ramming to dense.
