Medium frequency furnace charge can be divided into a variety of industrial production, according to the different material properties, medium frequency furnace charge can be divided into neutral, acidic and basic charge, the following Anaijie can tell you about the medium frequency furnace charge what kinds? What causes the charge to burst?

There are many kinds of medium frequency charge, which are divided into neutral charge, alkaline charge and acid charge according to the difference of acid and alkali, of which the medium frequency charge of different properties contains different kinds. Let's take a look at these types of intermediate frequency charges.

Intermediate frequency charge is also called intermediate frequency furnace lining charge, intermediate frequency furnace dry vibration charge, intermediate frequency furnace dry beating charge, intermediate frequency furnace ramming charge, etc., acid, neutral, basic beating charge, acid beating charge is high purity quartz, molten quartz as the main raw material, with composite additives as sintering agent;

1, neutral medium frequency charge is alumina, high aluminum material as the main raw materials, with composite additives as the sintering agent;

2, alkaline medium frequency charge is high purity fused alumina, high purity fused magnesia, high purity spinel as the main raw materials, with composite additives as the sintering agent.

Acid, neutral, basic medium frequency charge is widely used in coreless medium frequency furnace and cored induction furnace, as the lining material of medium frequency furnace to melt gray cast iron, ductile cast iron and cast iron alloy, melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, melt aluminum and its alloy, melt copper, brass, white copper and bronze and other copper alloys.

What causes the charge to burst?

The first reason for the explosion:

After the fine powder is introduced into the medium frequency furnace, many small voids are filled, which reduces the air permeability of the medium frequency furnace and causes the explosion.

Intermediate frequency charge burst cause two:

The zeolite-like calcium-aluminum-silicon hydrate or gel formed in the traditional medium frequency charge rarely forms an exhaust channel before 300 degrees due to the decomposition of the hydrate, and after 300 degrees, a large amount of water vapor is released by rapid dehydration leading to explosion.

Medium frequency charge burst easy solution:

1. Adopt reasonable drying and heating system to control the inside of medium frequency charge. Large vapor pressure;

2, in the medium frequency charge to add explosion-proof agent and other anti-explosion substances, in order to increase the permeability of the hardened body, reduce the steam pressure inside the castable.

If we encounter intermediate frequency charge burst in production, we need to pay attention to it, thank you for reading what kinds of intermediate frequency furnace charge and what causes the charge burst are introduced to you by Anetjer.
