It is divided into steel-casting, ironcasting, copper casting, aluminum casting, casting magnesium part, casting zinc part, casting titanium part etc..And it can be by its chemistry per class casting
Ingredient or metallographic structure are further separated into different types.As ironcasting can be divided into gray iron casting, nodular iron casting, vermicular cast iron
Part, mitis metal, alloy iron casting etc.;By the difference of casting mold forming method, casting can be divided into common sand-cast, gold
Genotype casting, die casting, centrifugal casting, continuous pouring piece, investment-casting, ceramic mould casting, electroslag remelting casting, bimetallic casting
Part etc..It is wherein most with the application of common sand-cast, account for about the 80% of whole casting outputs, and the non-ferrous metals such as aluminium, magnesium, zinc are cast
Part is mostly die casting.
Riser refers to avoid casting from the supplement part that defect is attached to casting top or side occur.Function is in casting mold
In, the cavity of riser is the cavity for storing liquid metal, and metal is fed when casting is formed, prevent shrinkage cavity and porosity, be vented and
Collect the effect of slag, and the main function of riser is feeding.The different riser of the design function of riser, form, size and opens up
Position is all different.
Existing frequently-used large-scale open riser, riser diameter is big, big with air contact surfaces, and heat loss is fast, and heat waste is serious,
If individually covering exothermic mixture, after exothermic mixture burns, exothermic mixture is easy to be fused into one layer of hard shell, by molten steel in riser with
Air exclusion is not easy to riser feeding, if independent covering and heat insulating agent, heat preserving agent, which can only play, reduces the work that heat distributes speed
With, it cannot play the role of heating to riser, so as to cause a same casting, need larger riser to carry out feeding, this
Sample is increased by castings production cost, it would be highly desirable to improve.
