The crucible should be stocked in the dry situation2. Carry the crucible lightly3. Warm the crucible in the drying machine or near thefurnace. The warming temperature should be up to 500oC.4. The crucible should be put under the furnace month flat.5.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.6.The clamps shape need as that of crucible. Avoid theconcentrate stressed destroy of the crucible. 7. Clean the crucible regularly and lightly.8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.9. Turn the crucible once in one week and this will help lengthen the service life.10. The flame should not touch the crucible directly.11.24 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 soupsolidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.12. 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.Quality ControlQuality policyThe policy aims at satisfying our customer by way of initializing an updated quality management and sticking to the top requirement of "quality first" in an attempt to achieve an elite project finally.Quality objective Provide our customer with products in full line with relevant contract and standard by way of strictly conforming to quality control procedure and intensifying avoiding common quality faults to be sure of an effective operation of the quality assurance and quality control system, achieve a zero quality accident rate and realize good project construction quality.Quality Assurance System and FunctionEstablish quality assurance and effective quality control system before construction in order to ensure the realization of construction quality objective.
