Characteristics of sintered calcium aluminate: 1) Uniform chemical composition, low melting point and fast melting speed can shorten the refining time; 2) No fluorine, no erosion of furnace lining and ladle; 3) Compact structure, no water absorption, easy storage and transportation; 4) Due to the stable phase and fast slag formation, it can reduce the dust pollution to the iron and steel plant and comprehensively stabilize the refining process; 5) It does not contain impurities such as hydrogen, nitrogen and carbon, which is conducive to improving the quality of steel. Sintered calcium aluminate (premelted aluminum calcium slag) is mainly used in LF furnace, open hearth furnace and converter ladle refining to remove impurities such as sulfur and oxygen in molten steel and reduce the content of harmful elements and impurities in steel. It is suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.

Calcium aluminate advantages: 1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time; 2) It has no fluoride and doesnt erode furnace lining and ladle, and it is compact, non-absorbent,and easy to storage as well; 3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel; 4) Improving the protective effect and reducing erosion to ladle lining.

Silica fume, also known as condensed silica fume or microsilica, is a spherical sub-micron amorphous silicon dioxide used in many applications. Silica fume is a co-product of silicon or ferrosilicon production, consisting of ultrafine (sub-micron), amorphous, non-porous, perfectly spherical silicon dioxide (SiO2) particles, with purity levels of 85 to 99 %. The main effect of these ultra-fine particles is to greatly improve particle packing and produce a highly pozzolanic reaction in concrete and other cementitious bond systems where the silicon dioxide reacts with calcium hydroxide, heightening performance levels and the strength and durability of these materials. Additionally, silica fume, because of its amorphous (non-crystalline) structure and its specific area, provides other useful features to various applications, including improved sintering capabilities and enhanced high temperature performance of refractory castables, resulting in reactions between microsilica and other components of the refractory mix. To summarize, silica fume has two key features which alone or in combination are the basis for its high performance: The nano-sized spherical non-porous particles create an efficient "filler effect" Primary particles have an average diameter of about 0.15 �¼m (150 nanometers) Microsilica is a highly reactive form of silica producing a "chemical effect" Thanks to its amorphous nature and high specific surface area.
