    1 ton melting furnace maintenance and repair method

    Melting furnace maintenance : 1 ton parallel intermediate frequency electric furnace usually maintenance and overhaul

    The 1 ton parallel melting furnace is inspected once a month to remove dust and dirt from the machine, and check whether the thyristor module and the bolts on the main circuit energizing circuit are loose and damaged. If it is loose, it should be repaired before use. Keep the cabinet clean and bright.

    1,    If the 1 ton parallel melting furnace is not used for the time being, the drying measures should be strengthened to enhance the ventilation to prevent the parallel melting furnace from being damaged by the tide .

    As well as the deterioration of various electronic components, the water in the system should be excluded in the winter to prevent freezing and damage to the pipeline.

    3. Since the overload capability of the semiconductor power switching device has been set, overload operation is not allowed.

    4. During the working process of the parallel melting furnace , it is not allowed to have any contact between the output circuit (inductor coil) and the machine.

    A line (short circuit) occurs, otherwise it will cause damage to the parallel melting furnace .

    5, the machine needs to adjust the parameters in a timely manner, so the user does not need to adjust any electrical appliances during maintenance.

    If the components are damaged and replaced correctly, they can be put into operation immediately

    6. The user unit should be equipped with special operation and maintenance personnel, and other personnel should not move. In case of human occurrence

    The fault or fault has expanded.

    7, the user unit should be equipped with maintenance instruments, such as multimeter, 20MHz dual trace oscilloscope.

    8. This parallel fault easily determine the melting furnace, and the SCR module easily damaged, available multimeter SCR

    CE bipolar resistance value of the module, generally as long as the CE poles short-circuiting thyristor modules can be considered normal. If the thyristor module CE is short-circuited, the information about the indicator lights of each control board can be checked and

    Output the signal to find out which board the fault is on, replace the new board, and repeat the operation of each part of the ¡°Debug¡± section.

    9. In summer, because the inlet water temperature is too low (compared with room temperature), condensation is likely to occur in the power cabinet. At this time, it is necessary to stop immediately, and try to increase the inlet water temperature until the condensation is removed.

    10. Keep the ventilation inside the machine so that the components on each control board dissipate well.

    11. In the power cabinet of 1 ton parallel melting furnace , if the surface of the circuit is covered with conductive dust, the oil should be wiped clean with acetone or alcohol in time to ensure trouble-free operation of the parallel melting furnace .
