Riser Heat Generating Agent
Product Description:
Exothermic Anti-piping Compound is used in foundries after pouring, to maintain the molten metal temperature in the upper part to stay nearly the same as the lower layer, and prevent piping defect in the casting.
Due to teh temperature of molten metals, Exothermic Anti-piping Compound will burn and provide reservoir od liquid metal for solidification (liquid contraction) during cooling process. After burning, an insulating layer will form to decrease heat loss. Cavities resulted from shrinkage will become more curve-like (U-shaped), instead of funnel-like(v-shaped).
Features:
1.High calorific value, outstanding performance on temperature insulation. It can keep high temperature of liquid steel in riser area to ensure continuous replenishment of hot steel, which ensure compact texture without shrinkage and osteoporosis to increase the finishing rate of castings.
2.When using this product, the riser would contraction with U-shape on the top, which can save 30%-50% hot steel on the riser to maximum increase the finishing rate.

Use Method:
After pouring, apply the compound on the surface of molten metals through sprue and riser/feeder head. The compound will react with molten metals and start burning to supply heat.
Application:
Grey Iron/ Nodular (Ductile) Iron, Stainless Steel/ Alloy Steel.
Note:
Store the compounds in a dry, cool and shady area and away from any sources of heat, flame or anything that may produce sparks.
