Chrome enriched magnesite based ramming mass for making ladles of foundry.Plain water to be used as binder before pre-heating.

Method to use: After mixing 3-4% of plain water, 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.

Magnesite based ramming mass for making the top & spout of induction furnace, with special bonds to form a strong chemical bond with Sodium Silicate.

Method to use: Material is to be mixed homogeneous with 4-5% diluted Sodium Silicate & water. Then after it is properly applied on the top and spout.

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.

We are main supplier of this product.

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.

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.

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.

It is quartz based ramming mix widely used in low cost melting of Mild steel, Alloy steels, Ni-hard, Ni-Resistant Chrome Irons, Ductile and Malleable Irons.The same is available in PREMIX variant where homogeneous mixing of boric acid as a binder is done.

This castables posses our brand name DI ALCAST - A and are manufactured using a high purity high alumina cement produced and marketed by us.The number in the brand name denotes the percentage of alumina content in these castables.
