Since sand core uses the technique of dip-coating material, sand core adsorption moisture is more, especially at the gap of assembly of sand core More difficult drying, it is therefore necessary to which forced air heat convection reasonably controls the air quantity of the air velocity of hot wind, makes hot wind shape in stove At turbulent condition, the coefficient of heat transfer of the penetration power of hot wind is further improved, supply air system should be furnished with hot wind guiding device in stove, So that hot wind is equably blown to sand core surface, make sand core thermally equivalent, avoids sand core surface because accumulation of energy is excessive or non-uniform temperature Coating surface crackle, uneven color or scaling loss resin film are generated, even metaboly occurs to cause sand core strength to reduce. The hot wind of the drying oven is directly blown to sand core surface through wind pushing box by circulating fan, is returned through air-intaking box after exchanging heat with sand core, And wind pushing box is imported after being reheated by combustor again, complete a cycle.
Meter dried furnace is equipped with 4 heating zones, and each heating zone individually controls, and is convenient for the setting and adjustment of stoving process.Each The hot air circulation mode of heating zone is dried for top, two side bottom air return structures, it is ensured that the abundant drying of mould surface.
Meter dried furnace divides preheating section and heating, soaking zone.In preheating section because the most of moisture of sand core surface coating is in this phase Between evaporate, sand core surface coating film goes to pot because moisture evaporation is too fast in order to prevent, and hot blast temperature needs control lower, Hot wind humid control obtain it is relatively high, be conducive in this way save the energy.It is relatively fewer in heating and thermal insulation section moisture steaming amount, to make sand The moisture of wicking surface is successfully migrated to appearance, and the hot blast temperature of this section is relatively high, and drying time is longer, and hot wind humidity is controllable System is in reduced levels, it is ensured that sand core drying dries saturating.
