  Installation and operation of elements

  1.In order to keep furnace temperature and the charges uniform of each element,before installation ,resistance distribution must be carried out . The resistance deviation among elements of each set should be 5%.

  2.As the element is very brittle ,be careful while install and maintain to avoid any damage.

  3.When start to operate the furnace, raise voltage slowly and gradually,never give full load at one time, otherwise,the heating element will be damaged by over current impulse.

  4.To use the elements, you should prepare the adjustable transformer or SCR controller, voltage meter, current meter and auto-control temperature meter etc. During the working ,the voltage should be increased to keep the furnace normal temperature because the resistance value will go up gradually caused by the oxidation of element. When the voltage get to the top limit of the transformer and the temperature is still low than the requirement, the furnace should be stoppde, change the way of wire connection and then continue work.

  5.In the course of long team operation, if any individual heating element is damaged owing to certain reasons, which should be changed,you should replace it with proper one whose resistance value corresponds to that of the old one,never use a new heating element random. If the heating element is much damaged or its resistance value increases too much and cannot reach the furnace temperature, it is better to replace all the heating elements with new ones. Test and mark the resistance value of the old elements having been replaced(with voltmeter and ammeter)and distribute them in low temperature area.

  6.Before use the new furnace of the furnace that has not been used for a long time, they must be dried. When drying them,it is better to use old elements or other heat source.

  7.When firing products or materisls, if there is water ejection, the furnace should have holes to eject water vapor or other waste gases in order to protect the elements service life.
