Description
Technical field
It is specifically a kind of to be centrifuged using all-metal mould mould the present invention relates to a kind of production of fluid-flywheel clutch workpiece
Pouring procedure produces fluid-flywheel clutch workpiece and production method, more particularly to a kind of UTILIZATION OF VESIDUAL HEAT IN using biomass aluminium melting furnace
The fluid-flywheel clutch workpiece and production method of device preheated mold and bearing holder (housing, cover).
Background technology
The production method of the fluid-flywheel clutch workpiece such as aluminum component housing such as turbine, pump impeller, shell generally comprises sand core casting, again
Power is poured into a mould and three kinds of die casting, and wherein the main of sand core casting is disadvantageous in that first, internal model is cast using core, to sand
Modeling requirement is high, high to the technical requirements of moulder；Second, core is fragile, by core positioning and Quick pouring, casts out and
Product easily there is center asymmetry, blade is uneven, and the defects of blade surface and rough inner chamber, fluid-flywheel clutch is existed
Circulation of oil flow resistance during use is big, loss power；Third, the product surface finish of core casting is not high, yield rate is low, makes
The site area taken needed for type is big, and sand is mostly discarded after having cast, not only not environmentally but also uneconomical.Gravity-assist pouring it is main not
The workpiece density that foot part is to produce does not reach requirement, and its qualification rate is merely able to reach 40 ﹪ or so.Also there is part enterprise
Industry uses low-pressure casting process, and low pressure casting is to lean on advanced equipment investment, and press is high with mould input cost, and fluid coupling

The main material of the workpiece of device is aluminium alloy, and the melting mode of existing aluminium alloy is mainly using electric furnace, gas furnace and common Jiao
Charcoal stove, ordinary coke stove do not allow to use from the policy requirements of environmental protection；Although electric furnace, gas furnace are fast and environmentally friendly, can only also do
Smelting furnace is used, and is grown in the centrifugal casting process time of all-metal mould, and aluminium water needs to be incubated, and such cost is high, especially for
For the product of small lot, cost is higher.Meanwhile metal die must make oven in addition and carry out mould heating heating.
Biomass aluminium melting furnace is the professional energy saving and environment friendly smelting furnace using bioenergy, is put english streaming using half gasification, and combustion
Air distribution designs, and using Crucible melting and heat-insulating integral, has coloured gold mainly for low melting points such as fusing or smelting aluminum, zinc, lead, tin, cadmiums
Category and alloy, it is typically supporting with die casting machine, it can also be used to aluminium liquid insulation, degasification, refining.With energy-efficient, low-carbon environment-friendly, life
The characteristics of cost is low, Operation and Maintenance is simple, flexibly safe is produced, is the best product of replacing fuel oil, combustion gas, coke-fired furnace, electric furnace, can
So that enterprise reduces the ﹪ of 30 ﹪~60 energy consumption cost.
