EBT Tap Fill

It is used in electric arc furnace with eccentric bottom tapping for free and easier opening of tap hole.

Product Description

EBT Filling Mass compound is high refractory granular material, which is used in electric arc furnace with eccentric bottom tapping for free and easier opening of tap hole. This does not sinter under steel making temperatures and hence remains highly flow able at high temperatures, thus gets out freely ensuring uniform stream of hot liquid. it also minimizes the impact of lancing or poking on tap hole refractory and hence increases tap hole refractory lining life.

Product Specification

  Tundish Spray mass

Spay mass/ Gunning Mass

Spray mass made by Adithya chemicals are refractory mix consisting of fines and additives which are installed with a Spraying Machine (can also be applied with a Gunning Machine). The working lining of Tundish plays an important role in providing quality and cost-effective steel.

Gunning Masses are also unshaped refractory materials (Products) made after blending graded refractory grains with suitable bonding agents and are installed with a Gunning Machine.

Chemical Properties:

  Olivine/ Dunite

Olivine/ Dunite Flour

The mineral olivine is a magnesium iron silicate with the chemical formula (Mg,Fe)2SiO4. It is a type of nesosilicate or orthosilicate. The primary component of the Earth's upper mantle, it is a common mineral in Earth's subsurface, but weathers quickly on the surface. For this reason, olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation. Olivine also has many other historical uses, such as the gemstone peridot (or chrysolite), as well as industrial applications like metalworking processes.

Olivine in cross-polarized light

The ratio of magnesium to iron varies between the two endmembers of the solid solution series: forsterite (Mg-endmember: Mg2SiO4) and fayalite (Fe-endmember: Fe 2SiO4). Compositions of olivine are commonly expressed as molar percentages of forsterite (Fo) and fayalite (Fa) (e.g., Fo70Fa30). Forsterite's melting temperature is unusually high at atmospheric pressure, almost 1,900 °C (3,450 °F), while fayalite's is much lower – about 1,200 °C (2,190 °F). Melting temperature varies smoothly between the two endmembers, as do other properties. Olivine incorporates only minor amounts of elements other than oxygen (O), silicon (Si), magnesium (Mg) and iron (Fe). Manganese (Mn) and nickel (Ni) commonly are the additional elements present in highest concentrations.

Olivine gives its name to the group of minerals with a related structure (the olivine group) – which includes tephroite (Mn2SiO4), monticellite (CaMgSiO4), larnite (Ca2SiO4) and kirschsteinite (CaFeSiO4) (commonly also spelled kirschteinite).

Olivine sand

Olivine sand is an ideal mineral to use for the production of manganese steel castings as it is chemically less reactive than silica sand. SiO2 reacts with MnO in the steel to form a MnSiO3 slag resulting in serious burn on defects. A further advantage is that olivine sand has a low thermal expansion rate compared to silica sand and its high thermal shock resistance furthermore reduces sand expansion problems.
