It has the advantages of high density, good toughness, heat large,
long heat-holding time, so as to prolong the clotting time of liquid metal,
saving feeding liquid metal, reducing the cutting area, increasing the rate of
qualified products, reducing cost.
The main characters of the fiber composite Insulation Riser head are light, high refractoriness, high temperature line with little shrinkage, high apparent porosity, small heat loss, good heat preservation ,economical and practical. It can eliminate the shrinkage porosity of the inner face of the casting pieces, improve the inner quality of the casting pieces, and also improve the feeding efficient of the riser apparently, reduce the liquid steel of the riser and improve the process recovery efficiency of the casting pieces. Now it is widely used in casting pieces ,such as cast steel, cast iron and non-ferrous metal.
Advantages: Prolong the coagulation time2.55--2.9 multiple than the sand mold riser, the molten steel for feeding reduce 50-70%, the production ratio improved as much as 25--30%, it can reduce the contact area of the riser and the casting piece in the process of the top riser. Compared with the common sand mold riser, it can reduce 60--70% of the cutting and grinding area ,which reduce the fee of clearing and reduce the cost.
The loose shrinkage defect also can be eliminated . You can harvest stable casting pieces in the automatic molding line. It can be used for cooling the riser for its febrile. It can also reduce the pouring system ,which is good for nodular iron casting.
