Riser Heating Supplement

The role of riser heating supplements 1. Delay the solidification time of the riser so that the casting is fully replenished. 2. The setting of the riser is reduced, the cost of the casting is reduced, and the process yield is increased by about 8%. 3. Delay the solidification time for 15-20 minutes, so that the oxides, carbides, gases, etc. in the cavity have enough floating time.

Product Description

- Product Name: Riser Heating Supplement
The role of riser heating supplements 1. Delay the solidification time of the riser so that the casting is fully replenished. 2. The setting of the riser is reduced, the cost of the casting is reduced, and the process yield is increased by about 8%. 3. Delay the solidification time for 15-20 minutes, so that the oxides, carbides, gases, etc. in the cavity have enough floating time.

Application: carbon steel, alloy steel, stainless steel

Main ingredients: carbon, aluminum, silica, aluminum oxide, sodium ferric oxide

Principle of riser insulation supplement

1. The traditional feeder feeding is heated by adding aluminum. The melting point of aluminum is 660°C. It is not much to increase the temperature of molten steel above 1500°C by completely heating 660°C of aluminum.

2. Ishikawa brand riser heat preservation and replenishment agent does not rely on aluminum heating to keep warm and replenish, but relies on completely blocking the heat of molten steel at 1500°C from overflowing, prolonging the solidification time, and achieving replenishment and eliminating shrinkage porosity and shrinkage defects.

Main functions of riser heating supplement

A, solve the shrinkage, shrinkage defects.

1、Riser heating supplementIn case of high temperature, the volume increases, thickening, the formation of a protective film, to prevent the internal heat out, to extend the solidification time

2, Can make the solidification time of the riser is much later than the solidification time of the casting, play the role of feeding, to solve the problem of shrinkage, shrinkage

B. Solve slag and pore defects

As the solidification time of the riser (pouring cup) is prolonged, the slag, gas and oxide in the cavity have enough time to float up to the riser (gate), thus solving the problem of slag and porosity.

C, Improve the process yield.

1, Due to the extension of the feeding time, the gating system can be reduced than the original

2. The setting of riser can be reduced by 30%-50%, and the process yield can be increased by about 8%.

None

Relevant knowledge

Ishikawa brand riser fever tonic

As we all know, casting in the solidification process will produce shrinkage and shrinkage defects, which is also a very headache for the casting industry. The traditional treatment method is to add the corresponding riser to make up the casting solidification process. However, due to the many factors affecting the production of castings, it is impossible to rely on the feeding of the riser to achieve the desired effect, resulting in a high scrap rate of castings. In order to improve the effect of feeding, now more is the riser covering agent, covering agent has played a certain role in heat preservation, but the riser after cooling its surface shape is still flat, and did not play the role of heating and feeding. Ishikawa brand riser feeding agent effectively solves the problem of casting feeding.
