Cast iron and steel casting process with intermediate frequency furnace 25 tons/ batch

In the iron and steel manufacturing industry, intermediate frequency furnaces play an important role in melting and mixing alloy and metal products. So, how does the process of casting iron, intermediate frequency furnace 25 tons / batch take place?

First, we need to understand what is a intermediate frequency furnace?

Intermediate frequency furnace is a type of induction furnace, effective for me, ram mechanical parts, melting metal, firing billets for forging and pressing. Intermediate frequency furnaces operate on the principle of using induced current to produce heat that melts metal.

Basic parts of intermediate frequency furnace

Intermediate-frequency furnace has 2 parts, they are  an electric induction furnace and a furnace.

• Electric induction furnace is a system consisting of an electric motor, power frequency generator, induction coil and induction coil capacitor.
• Non-conductive induction furnace, furnace frame and support device tilt the furnace.

When cast iron, steel with intermediate frequency furnace 25 tons / batch needs to know the exact mixing ratio, chemical composition by time I train very quickly, just enough to analyze some of the main components in the product.

1. Advantages of casting iron and steel with intermediate frequency furnace of 25 tons / batch

• Thermal energy transfer helps quickly process molten material without going through intermediate steps. Saving energy, saving electricity, easily heating in neutral, vacuum environment.
• The training time is very short, I can detail the surface to make everything I have any shape. Low material loss rate, product quality is precisely controlled and guaranteed.

The whole system of intermediate frequency furnace has safety protection equipment, easy to use, compact and easy to maintain.

2. Process of casting iron, with intermediate frequency furnace 25 tons / batch

Step 1: Check the middle frequency furnace system

• Check the internal structure of the furnace: make sure the kiln wall is over 10cm thick, the furnace is not corroded and the burning material must be worn evenly.
• Check the safety of the entire system and the normal performance of each part.
• Need to calculate and prepare all kinds of metals and auxiliary materials
• Tools to support the process of tempering by frequency furnace such as sample molds, sample ladders, chemical composition analysis system ....

Step 2: Melting and melting to cast iron and steel with intermediate frequency furnace 25 tons / batch

• Put raw materials into a intermediate frequency furnace, ensuring no excess or excess to below 1.5 tons of material. Allowing the power from a small level of about 40% then raising it to 100% to increase the speed of shortening the melting time.
• Continue to put the material into the second furnace after finishing melting the material for the first time, it is absolutely forbidden to let the molten material clean up because it will affect the wall thickness.
• To ensure clean filtration in the furnace, use an inclined support tool to filter.
• When the material in the furnace has been heated to about 70%, take a sample to analyze and measure the chemical composition of the material, to adjust and supplement according to the required ratio.

Step 3: Casting successfully iron and steel in intermediate frequency furnace 25 tons / batch

In order to end the melting process with 25 ton / batch frequency converter, it is required that the analyzer of chemical components on the product must match the standard.

• When the melting temperature of the material has reached 1680 degrees C, it is poured, the first pouring into an intermediate pouring tank larger than 10 to 20 degrees C.
• Continuous reduction of oxygen in liquid material before casting cast iron and steel

After that, the crane will carry the intermediate pouring tank to the cast iron and steel casting position and pour casting. Finish the process of casting iron and steel with intermediate frequency furnace of 25 tons / batch
