Difference Between Cupola and Electric Furnace
Hello everyone, I am the youngest girl in the factory.
Everyone knows that cupola hot metal
is better than electric furnace,
but what is the reason?
Because the cupola smelting process is
when the molten iron droplets fall on the surface of the coke,
it causes the unevenness of the microscopic carbon
increase of the molten iron.
Therefore, the degree of crystal supercooling is small,
the crystal grains are refined,
and the white mouth is not easy to produce.
The electric furnace smelting molten iron is carried out
under...
The temperature suitable for casting discount
Hello everyone, I am the youngest girl in the factory.
Is the higher the casting molten iron temperature, the better?
The selection of molten iron temperature should consider
the wall thickness,
size and grade of the casting.
Generally, the larger the wall thickness,
the lower the pouring temperature and the overheating temperature;
With the higher the grade, the lower the carbon equivalent and
the higher the temperature of the molten iron.
Sometimes, despite the higher pouring temperature of
high-grade castings,
However, the flow capacity of molten...
Get the right spheroidizing temperature
Hello everyone, I am the youngest girl in the factory.
What is the appropriate spheroidizing temperature?
The proper spheroidizing temperature should ensure
the full effect of the spheroidizing agent,
the oxides with lighter specific gravity than iron,
inclusions and gases can fully rise to the scum,
and the suitable processing temperature is 1400°C both
internationally and domestically,
and the loss of the spheroidizing agent is too high.
Too large or too low is not conducive to
oxide slag inclusion and gas floating.
The temperature...

Reasons for damage to intermediate frequency furnace lining
Hello everyone, I am the youngest girl in the factory.
It's time for the popular science class again.
Today we are going to talk about the reasons and solutions
for the damage of the lining of the intermediate frequency furnace.
The main influencing factors that damage the furnace lining are: chemical corrosion of slag,
spalling of refractory material structure
and thermal corrosion.
1) The lining material should have the characteristics of
high thermal strength, low air permeability and low porosity.
2) The initial failure of the lining is due...

How to prevent the recession of spheroidization, the key to see 4 points
Hello everyone, I am the youngest girl in the factory.
It's time for the popular science class again today!
Today we will talk about some measures to prevent
spheroidization and recession:
1. The time from incubation to pouring must be short,
the longer the time, the more serious the incubation decline;
2. The molten iron should maintain a proper amount of
spheroidizing element content
3. Reduce the sulfur content of the original molten iron and
prevent the molten iron from oxidizing
4. After the molten iron is spheroidized and slag removed,
the surface...

What is a good nodulizer?
You see, I have two samples of spheroidizing agent on my hand,
and they all look the same.
Let me do a testing experiment for everyone.
This is the indicator required by the customer on our contract
This is produced by our family,
and all ingredients are well controlled according to
customer requirements.
This is the spheroidizing agent that the customer originally used,
but the spheroidizing grade cannot be reached after using it,
so I replaced it with our...
In the smelting process, how to choose ferrosilicon?
Hello everyone, I am the youngest girl in the factory.
In the smelting process, how to choose ferrosilicon?
This is the test result of two different compositions of ferrosilicon.
As you can see, the content of silicon in the
75 ferrosilicon below is high, but there are few impurities.
The above 72 ferrosilicon contains less silicon
and contains many impurities,
which is difficult to control during smelting.
Pay attention to me, the youngest girl in the factory,
there will be nodulizer testing tomorrow~

Pay attention to me, the youngest girl in the factory, I will take everyone to test the raw materials in the next...
Four Cheats for Cast Iron Melting in Intermediate Frequency Furnace!
Hello everyone, I am the youngest girl in the factory.
Some netizens left a message asking how to improve the strength of cast iron smelted in an intermediate frequency furnace. It is often said that the composition determines the organization, and the organization determines the performance. This sentence is basically correct, but it is not comprehensive.
In addition to the composition factor, the cast iron smelting should focus on the following four aspects:
1. The chemical composition of the molten iron should be accurate...
Who are our customers?
Today we are back to the factory again to see what the masters are doing?
Now the masters have just installed the car and are ready to ship it. They are about to be shipped to the hands of various customers. Many netizens are curious about which customers we serve.
We are involved in products such as spheroidizing agents, inoculants, vermicularizing agents, covering agents, steel-making deoxidizers and alloy core wires for cast iron. Most of the customers served by our factory are factories in machinery manufacturing related industries at home and...
The role of metal calcium in the smelting process
Today, let’s talk about metallic calcium metal, in the smelting process, has the function of purifying molten iron and slagging.
The metal calcium used in our factory is a single calcium element, and the model is above 999. Some people use calcium silicate, which has many impurities and complex composition. If there are too many ingredients in raw materials, it will be difficult to control. Eventually, the spheroidizing agent will be unstable.
follow me! I am the youngest girl in the factory. I still want to know what little...
