Difference Between Cupola and Electric Furnace
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
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
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
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
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 nodularizer?
Hello everyone, I am the youngest girl in the factory. 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?
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~

Four Cheats for Cast Iron Melting in Intermediate Frequency Furnace!
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...

The role of metal calcium in the smelting process
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...
