Dfc-600 type heat insulation covering agent for cast iron riser

Dfc-600 type heat insulation covering agent for cast iron riser

The new products developed jointly by our company and relevant scientific research institutions are suitable for open riser and sand mold common riser of cast steel, nodular iron, gray iron and other castings, and also suitable for heating and heat preservation of metal liquid in medium-sized subcontracting. Dfc-600 series products of heat preservation and heat covering agent for riser are applied to the surface of open riser, which can effectively insulate the heat radiation, heat convection and reduce heat transfer of metal liquid through the surface of riser Guide. The product can obviously improve the shrinkage shape of the riser, make the surface of the riser shrink in the shape of (saucer) or (Pan), effectively prevent the formation of the tapered shrinkage surface and the central shrinkage tube, increase the safe distance of the riser, and can be used in various steel castings and iron castings to heat and keep the temperature, prevent the formation of the casting shrinkage hole, and prevent the temperature drop of the molten metal in the middle subcontracting. The yield of cast iron can be increased by 25-35%, and the most conservative can be increased by 20%.

2、 Product use:

2、 Product use:

It is suitable for the heating and heat preservation of riser such as open riser of cast steel and cast iron and common riser of sand mold. It is also suitable for the heating and heat preservation of liquid metal in the middle subcontracting. Covering the riser, the product immediately burns and heats up, prolongs the setting time of the riser by 4-5 times, keeps the temperature for about 30 hours, and does not affect the quality of the original metal.

3、 Product features:

3、 Product features:

1. The product shrinks in the shape of (saucer) or (Pan) without insulating riser sleeve. That is to say, the shape of riser shrinkage hole is similar to "U"
