When we purchase a new crucible, how should we use? The following is a brief introduction of crucible, I hope you like it.

Whether it is for heating or heat preservation, all new crucibles must be preheated before they are first used or completely cooled. In order to make the crucible reach the most stable state and the longest service life, the heating cycle must be strictly carried out in accordance with the heating period prescribed by the crucible manufacturer, and the heating temperature shall be prohibited directly. No matter what type of furnace is used, or whether the crucible is used for heat preservation or melting, the preheating cycle of the crucible depends on the material of the crucible and the molten metal.

For induction furnaces, the frequency of the furnace, the size of the coil and the coefficient of resistance of the molten metal must be taken into account during the warm-up cycle.

In any case, the crucible preheating must be carried out at the initial stage, so as not to cause damage to the crucible.

For a crucible for transferring metal solutions, proper preheating is also required.
