Buy a New IF Induction Furnace and Know These When Using It


A medium-frequency induction furnace is one of the main mechanical equipment for metal induction thermal processing, which has the characteristics of a stable melting process and high efficiency. But if an induction furnace is in the process of use, there will be some safety risks.

Judian IF induction furnace

Concerning the use of induction furnaces, there are many things to pay attention to in smelting operations. Judian editor summed up some knowledge in this respect, and today to share it with you.

Pig Iron: For the medium-frequency induction furnace with the advantage of fast smelting, it is agreed that it is better to add pig iron in the early stage of smelting. This is because the shape of pig iron is relatively uniform, and it is easy to obtain high induced current, which is conducive to improving the smelting speed.

Carburizing Agent: for medium-frequency electric furnaces, it is best to gradually add carburizing agents when the metal charge is added. If added too early, the carburizer will adhere to the bottom of the furnace near; If added too late, it will not only lead to the delay of the adjustment of molten composition in the furnace but also may cause the error of excessive heating.

Ferrosilicon: the higher the Si content in liquid iron, the slower the carburizing speed when adding a carburizing agent. Therefore, adding ferrosilicon later for the medium-frequency induction furnace with weak stirring force is better. The addition time is too early, the metal charge has not yet melted, which will also play the opposite role of promoting oxidation.

Metal Charge: induction furnace smelting, although not frit, if from the start of the power is filled with charge, will make the equipment load large and hinder frequency transformation. In addition, parallel frequency conversion intermediate frequency induction furnace in the state of high load when the frequency change disorder, for this reason, the metal charge or successively added for good.

Precautions for heating up: When the electric furnace is heating up, to avoid the change of the properties of liquid iron during this period, the furnace cover should be closed as far as possible to prevent the heat dissipation of the liquid iron surface and achieve rapid heating up.

From a safety point of view, do not add the charge in the later stage of melting, because in the already heated large amount of molten iron, add the pig iron with rust and moisture, when it is immersed in the depth of molten iron, it will explode, causing molten iron splashing.

When the intermediate frequency induction furnace operators are working, they must wear protective equipment, such as gloves and protective clothing, to ensure their safety. It's also the most important part of any job.

Managers should be guided and trained in their daily work. Strengthen the staff the medium frequency induction furnace equipment safety production knowledge, and develop good habits, used to deal with some common emergencies.

This is our sharing of the smelting operation of the induction furnace today. I hope it can be helpful to you.
