This refractory mix is high alumina mix where in predominant aggregate component of alumina imparts a strong skeleton aggregate structure of superior uniform heat stability. The refractory mix is characterized by an ability to withstand corrosive-erosive attack of molten metal's and their acids, semi basic and basic slags during repeated exposure thereto, together with excellent volume stability, superior structure heat stability, low apparent porosity, a high contact angle with molten steel and strong abrasion resistance matrix.

The practice of oxy-assisted melting in EAF has been established for a very long time. Similar practice is adopted in induction furnaces also for purging of gases like Argon, Nitrogen. Normally steel tubes are used for purging of desired gases.

Fosterite based ramming mass for making laddles of foundry. Diluted sodium silicate to be used as binder before pre-heating.
Method to use: After mixing 4-5% of diluted sodium silicate, good compact ramming is required to be done, talking special care of the impact area which is the bottom. After completing the ramming process slow pre-heating is requied to be done for 3-5 hours (depending on the capacity of the laddle). There after laddle is to be kept in red hot condition for one hour.

This is a magnesite based ramming mix for medium / high frequency induction furnace, melting various types of ferrous / non-ferrous metals. Processing of the raw material is done with modern machineries to avoid any sort of contamination. Tailor made material is manufactured keeping in view the size of the crucible and type of the metal.

Material is to be used for the patching of worn out parts of the crucible. Cracks in the lining can also be filled with the same.
Method to use: Material is to be mixed with 5-6% 1:1 solution of Foundry Grade Sodium Silicate and water. Homogeneous mixing is required to be done. Area to be patched should be neatly dressed off slag, for better performance.

Material is to be used for giving coating to water cooled copper coil.
Method to use: Homogeneous mixing is required to be done with 6-8% of plain water in order to get material in the form of paste. It is to be applied on coil. Drying can be done by putting 500 / 1000 watt bulbs insite the crucible.

Ferro alloys are used in the process of steel making for addition of alloy content in the steel. We produce briquettes from undersize ferro alloys. Undersize ferro alloys cannot be used in the steel making process, we briquette this under size ferro alloys into uniform shape, size and dense briquettes. Apart from our standard sizes, we can make specific sizes as per customer requirements. The briquettes manufactured by us are sintered briquettes and not chemically bonded, thus we are able to deliver density and strength as much as the prime ferro alloys lumps. The yield of alloy from our product is generally higher as compared to prime ferro alloys lumps as our each briquette is of uniform shape, size and weight.

The practice of oxy-assisted melting in EAF has been established for a very long time. Similar practice is adopted in induction furnaces also for purging of gases like Argon, Nitrogen. Normally steel tubes are used for purging of desired gases. Ceramic coating helps reduce this consumption by a great extent resulting in following advantages:
Longer lancing time without interruption
More effective use of the unburned gases leaving the furnace and safety of the operator.
