Rotary kiln is one of the key equipment in mineral hot furnace RKEF process. the rotary kiln operation rate depend on the refractory working layer and refractory materials & installation quality .
Hongda high performance refractory castables include low cement,ultra low cement and anhydrous castables,characteristics with high strength,good volume stability,good thermal shock resistance.
Basic tundish gunning mass is binding with inorganic binders,and no harmful gas released when baking, no environmental pollution,reduce the phosphorus, carbon pollution, and can purify the molten steel,which can meet the requirements of different types of steel smelting,meet the iron and steel industry continuous operation requirements,improve the molten steel output and economic benefit.
Fire clay refractory mortar is normally divided into four types according to physical and chemical indexes. It is mainly the auxiliary product for fire clay brick construction,with the refractoriness of 1580~1750℃, water content of ≤6%. The Fe2O3 content in refractory mortar for blast furnace construction shouldn’t be over 2.5%.
With high melting point of alkaline oxide, magnesium oxide (melting point 2800 ℃) and hard to slag invasion of high melting point carbon materials as raw materials, all kinds of oxide additives.Carbon composite refractory materials with carbon binding agent.
Straight through-hole ventilated bricks are often formed by vibration casting and by means of reserved holes.
The ladle diversion sand is made of quartz sand and high-grade chrome ore sand as main raw materials and certain amount of additives, and the grades can be selected according to the refining condition of the ladle.
Straight through-hole ventilated bricks are often formed by vibration casting and by means of reserved holes.
There are many types and forms of Ladle Porous Plug, which can be roughly divided into: diffused type, through-hole type, and slit type.
Fire clay refractory mortar is normally divided into four types according to physical and chemical indexes. It is mainly the auxiliary product for fire clay brick construction.
High construction efficiency can ensure the integrity, the construction of the uniformity and density.
