Grind-Chem's nozzle filling compound is highly refractory material with uniform grading which does not sinter at high temperatures and thus having excellent flowability. This is used in slide gates of tundish or ladle to ensure free opening of ladle tundish by preventing skulling and jamming of liquid steel at nozzle openings. Benefits Ensures free opening of nozzle. Minimizes oxygen lancing or poking. Acts as a desulphurising agent also. Prevents the ladle from not getting utilized in casting.

Grind-Chem manufactures covering compounds used in ladle and tundish. Our covering compounds are highly insulating powder, which has very good expandability and spreadability, so that it expands and spreads instantly to cover entire molten steel surface in the ladle and tundish. Covering compound can be acidic, basic or neutral in nature depending on the refractory linings used, casting conditions and grades of the steel cast. These covering compounds being highly insulating in nature significantly reduces heat loss due to radiation from the top surface of liquid steel. This results in maintaining consistent temperature in the ladle and tundish and also prevents temperature drop and freezing of metal in longer duration casting. These covering compounds also prevent molten steel to get exposed to atmosphere to prevent oxidation thus producing better quality steel. Benefits Minimizes ladle skulling or Jamming. Minimizes heat loss due to radiation significantly. Prevents direct contact of liquid steel to atmosphere. Increases wait-time of hot metal in the ladle or tundish. Maintains consistent temperature of hot metal in ladle tundish.

Our Ingot Teeming Flux are free flowing powdered flux that is suspended inside the Ingot mould while casting of Ingots. These flux when comes into contact with the hot liquid forms slag which moves towards the surface of the ingots. This slag as it moves upward absorbs the inclusion and impurities from steel, thus producing cleaner and better quality steel .It also provides enough lubrication between Hot Steel and Ingot mould, thus ensuring better ingot surface. The powdered layer at top also provides insulating layer on the top surface of hot liquid, thus preventing atmospheric reaction with hot steel and temperature loss at ingot head.

Grind-Chem's EBT Filler 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.

Our Mould Flux are designed in such a way to have uniform melting temperature range, most desired viscosity, slag thickness and crystallization tendency, optimum melting rate and suitable break and solidification temperatures. These parameters varies according to casting parameters and grades of cast steel and needs to be adjusted suitably so that following benefits are achieved during continuous casting.

There is an old saying in Steel making process - "Take care of Slag, Slag will take care of Steel". Improper composition of Slag is very detrimental for the quality of steel as it can lead to harmful reversion of P, S, and unwanted oxides. Our Synthetic Slag adjusts the Slag composition in such a way that it interacts with steel in a very balanced way thus maintaining proper equilibrium with the Steel. This helps in absorbing inclusions and impurities, and thus producing cleaner and better quality steel. Our Synthetic slag also adjusts the basicity of Slag, lowers the melting temperature of slag and increases its fluidity. This helps the slag to remove sulphur from the steel in form of sulphides, which moves easily towards more fluid slag. Hence it can also acts as desulphurising agent. The increased basicity and fluidity of slag also minimizes the erosion of refractory lining thus increasing the ladle life greatly.
