How to Extend the Service Life of Medium-Frequency Induction Furnace Equipment—Kangda Induction Furnace Equipment
Jul 03,2020
The technological development and promotion of medium-frequency induction furnaces are meeting the growing demand in the field of metal thermal processing.
During operation, the medium-frequency furnace utilizes the principle of electromagnetic induction, making it more energy-efficient and environmentally friendly compared to traditional coal-fired furnaces.
During the later stages of operation, the medium-frequency furnace requires proper basic maintenance and management to prevent issues such as failure to start up normally, unusual noises, and thyristor burnout.
(1) Inspect and clean the radiator to maintain efficient cooling performance; if necessary, perform acid cleaning.
(2) Check whether the water-cooling system has any blockages or leaks, and verify that the water pressure relay is sensitive. The temperature difference of the incoming water should generally not exceed 35℃.
(3) Check the insulation condition of the induction coil and whether there are any leaks.
(4) Check whether the wires and switches are damaged.
(5) Inspect and clean the sink, check the drain valve, and remove some wastewater to prevent scaling.
(6) Clean oil stains and dust from various electrical components and other equipment; use a fan or air pump to remove dust.
(7) Check that all wiring screws are tightened to ensure good contact.
(8) Check whether the thyristors, busbars of electrical circuits, transformers, and various circuit segments exhibit any signs of overheating.
Medium-frequency induction furnaces are widely used in everyday life, and this widespread use is closely linked to their effective maintenance practices.
First, conduct thorough inspections before startup—especially for the furnace lining. Check whether it is intact and inspect for cracks, furnace openings, erosion, and furnace nozzles to ensure smooth operation during startup.
Second, before adding the pig iron, the amount of scrap steel to be added should be determined based on the impact of the pig iron on the furnace bottom. After the iron has melted, carbon-increasing agents, scrap steel, and returned material can be added.
Third, when placing the charge materials into the furnace, avoid any impact of the charge materials against the furnace lining. Additionally, to address the occurrence of charge bridging and crust formation, you can reduce the power output for treatment.
We recommend that everyone use the medium-frequency induction furnace appropriately and strictly follow the operating guidelines to avoid causing unnecessary damage to the furnace.
