Refining and Purifying Agent Outside the Furnace

Characteristic:

This product can aggregate micro inclusions and bubbles, increase their volume and bob up quickly.

It is used to remove oxides, inclusions, and gases from molten metal, increase fluidity and improve surface smoothness of castings.

Instructions：

Put purifying agent into empty molten iron ladle, then fill it with molten metal, sprinkle with deslagging agent, cover with insulation for 2-5 minutes. The dosage is about 1‰.

Pay attention, do not remove the slag while pouring, use slag blocking cotton to block the pouring slot.

Packaging and storage

Packed in sealed iron drums, 33.5kg/drum.

Riser Filling Agent

Characteristic:

This product spontaneously ignites and generates heat when exposed to high temperatures. After combustion, it forms a tight insulation film to prevent internal heat dissipation. It can delay the solidification time of the riser surface by 10-20 minutes.

It is used for sufficient shrinkage, solving porosity and shrinkage completely, the oxides, inclusions, and gases in the mold cavity have enough time to emerge from the metal surface to solve the slag blowhole problem.

Instructions：

Add riser filling agent immediately when the metal liquid in the riser rises to the flat , and it must be added again after re-pouring.

The dosage depends on the material, thickness and size of the casting, usually 2~3 cm or 5~10 cm, if extra large piece, added the whole package.

Pay attention, do not pierce the insulation film after adding the reinforcing agent to prevent internal heat dissipation and solidify prematurely.
