Medium- and High-Frequency Induction Furnace Coil Insulation Scheme
Oct 01,2020
Induction coil Arcing and sparking in medium-frequency and high-frequency melting furnaces are common phenomena that seriously affect equipment safety and production efficiency. At best, they lead to a decline in equipment productivity; at worst, they can cause equipment damage, result in production accidents, and endanger people’s lives and property. This issue must be given the highest priority!
A wealth of evidence proves that, Coil The direct cause of the fire was the breakdown of the insulation layer on the coil surface, which resulted from a short circuit under high-voltage and high-current conditions. Therefore, ensuring long-term effective insulation of the coil surface is the only way to address this issue.
One of the primary causes of insulation layer damage is the prolonged operation of equipment in high-temperature environments. However, the higher the temperature, the faster the insulation layer ages, leading to a rapid loss of insulating performance in low-temperature-resistant coatings within a short period. Excessive temperatures—such as those caused by scaling inside coils, interruption of cooling water supply, or excessive thinning of the furnace lining after prolonged service—can result in temperatures exceeding the insulation layer’s maximum tolerance limit, thereby causing irreversible damage to the insulation.
In addition to temperature resistance, the insulation performance, adhesion, strength, toughness, and ease of application of insulating varnishes are also important factors to consider.
