Preheat for 3 hours at a constant temperature at 200 degrees;> Preheat at a constant temperature of 700 degrees for 2 hours;> Preheat at a constant temperature of 900 degrees for 1 hour;> Shut down the furnace to cool the crucible to no redness;> Then the temperature is raised to the normal aluminum melting/feeding temperature and the feeding is added in a vertical direction of 90 degrees.Notes of operating crucibles> The crucible should be stocked in the dry situation;> Carry the crucible lightly;> Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500ºC;> The crucible should be put under the furnace month flat;> When put the metal into the crucible, you should take the crucible capacity as your reference. If the crucible is too full, it will be damaged by expansion;> The clamps shape need as that of crucible. Avoid the concentrate stressed destroy of the crucible;> Clean the crucible regularly and lightly;> The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace;> Turn the crucible once in one week and this way can keep the service life;> The flame should not touch the crucible directly;> 24 hours constant use will make crucibles have longer service life;The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup solidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.> We suggest that about 2 months for crucible melting aluminum alloy (every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation ishelpful to prolong the service life of crucible./p1. The crucible must be stored in a dry environment, preferably on a wooden pallet, and kept well ventilated;2. The crucible can be stacked when placed upside down; 3. The crucible must not be exposed to a humid environment, otherwise the glaze layer of the crucible after absorbing moisture will easily peel off during the crucible preheating, which will cause the graphite to be oxidized, and the thermal conductivity of the crucible will gradually decrease, which will reduce the service life of the whole crucible.Used in these industriesp>
