Powerful raw materials
I am the youngest girl in the factory.
The raw materials for this issue are a bit powerful.
This is the metal calcium storage area.
We don’t use calcium silicate because there are many impurities and complex components.
The metal calcium in our household is a single calcium element, and the calcium content is more than 99.9%.
This is our raw material silicon barium, the barium content is 30%.
Follow me, the youngest girl in the factory.

Our raw materials
I
am the youngest girl in the factory.
This
issue will continue to show you the raw materials.
Let's
talk about magnesium ingots first.
We
all use magnesium ingots with a magnesium content of 99.9%, all
purchased from Fugu, Wenxi and other places.
This
is our rare earth storage area, all
of which are lanthanum and cerium metal rare earths, which
are refined by metal smelting and have less impurities.
Follow
me, the youngest girl in the factory.
The
raw materials in the next period will be better.
The casting raw materials you want to see
I am the
youngest girl in the factory.
In the last
issue, I talked about what the
products produced by the factory.
In this
issue, I will show you what the raw materials of these
high-quality nodulizer inoculants.
This is the
ferrosilicon storage area we use.
All we use
are 75A ferrosilicon, purchased directly from Ordos,
Qinghai Huadian
This is our
scrap storage area, we use A3 steel, free of rust
and other impurities.
Because
spheroidizing agents are very taboo impurities, such as Cr,
Mn, Ti, Ni, these are de-spheroidizing elements,...
Master craftsmanship-silicon barium inoculants
I
am the youngest girl in the factory. Why
do you say I am the youngest?
Because
our factory is full of masters, they
have very rich experience.
When
customers encounter problems, they
will consult them.
In
fact, there are many masters in the factory.
They
don't understand publicity or marketing.
They
just focus on technology and product research.
Technology
can indeed replace manpower now, but
the experience of the older generation cannot be replaced by any technology.

shining! Guess what compound inoculant is this?
Advantages of silicon strontium inoculant: cast iron is an iron-carbon alloy with a carbon content of more than 2.1%, gray cast iron is a kind of cast iron, the graphite in gray cast iron is lamellar, and the fracture is dark gray. The main components of gray cast iron are iron, carbon, silicon, manganese, sulfur, and phosphorus. Gray cast iron has low cost and good casting performance and use performance. Therefore, gray cast iron is an important and commonly used structural material in modern machine manufacturing and is the most widely used. The output of cast iron accounts for more...
Which domestic cast iron do you use?
The percentage of cast iron market output by classification, have you reached the standard?
Cast iron is divided into gray cast iron, nodular cast iron, malleable cast iron and vermicular graphite cast iron. Among them, gray cast iron is the most widely used, with an application rate of 80%, spheroidal graphite cast iron accounting for 15%-18%, and the remaining malleable cast iron and vermicular graphite cast iron.
How is nodular cast iron formed, and what is the future prospect of nodular cast iron?
Nodular cast iron is a high-strength cast
iron material developed in the 1950s. Its comprehensive properties are close to
steel. Based on its excellent properties, it has been successfully used to cast
some wear-resistant parts with high strength and good toughness. Nodular cast iron has rapidly developed into
a cast iron material second only to gray cast iron and widely used. The
so-called "substituting iron for steel" mainly refers to ductile
iron. Nodular cast iron is obtained by spheroidization and inoculation
treatment to obtain nodular graphite, which effectively improves...
Hydrometallurgy is the most widely used metallurgical technology
Zhang Qian, a
famous hydrometallurgical smelter in the Northern Song Dynasty of my country,
was the first person in hydrometallurgy in the world. He once saw the record in
the book that bile vitriol water can soak iron into copper, so he experimented.
Bile water leaching of copper, that is, the use of copper sulfate solution to
immerse iron to cause a chemical reaction to precipitate copper. The method can
be called a major invention in the history of Chinese metallurgy and chemistry.
Modern hydrometallurgy is a science and technology that uses leaching agent to
dissolve valuable...
Metallurgy is the most dynamic manufacturing technology in new materials science
This issue reveals
the hardware manufacturing process recognized as a green process: powder
metallurgy.
Powder metallurgy
is a process of manufacturing various types of products by forming and
sintering metal powder or its mixture as raw materials. At present, powder
metallurgy is widely used in mechanical processing, drilling, electrical
appliances, mechanical automobiles and other fields. The powder metallurgy
process is also one of the most widely used processes in the industrial field.
The development of
China's science and technology has made our...
How much do you know about the history of domestic metallurgy development?
Do you know the history of metallurgical
development in ancient and modern China and abroad?
The earliest known iron tool in China is
the Shang Dynasty iron blade unearthed in Hebei. It was later confirmed that it
was forged from meteorite with higher nickel content. In addition, there are
the meteorite iron blades of Pinggu, Beijing, and the bronze iron blades of the
late Shang Dynasty in Henan. These indicate that the early use of natural iron
by primitive peoples was universal.
There are rich iron deposits in many areas
of our country. Especially...

Production process of silicon barium inoculants
What is silicon barium inoculant?
The silicon-barium inoculant is a large metallurgical material prepared from silicon powder and barium powder in proportion to high-temperature furnace steelmaking according to needs. It is an additive in the casting process, which can promote graphitization and reduce the tendency of white mouth. , Improve the morphology and distribution of graphite, increase the number of eutectic groups, refine the performance of the matrix structure, and have a good effect in a short time (about 5×8 minutes).
Silicon barium (long-acting inoculant) content:...
Silicon strontium inoculant 0.2-0.7
1. Performance
Strong inking inoculant, its inking ability is significantly better than 75 ferrosilicon. Compared with carbon-silicon calcium inoculant, inking ability is similar, but it has a low melting point, good solubility, low calcium content, and less slag. Allows a lower incubation temperature. Compared with ferrosilicon and barium ferrosilicon, its outstanding feature is that it does not significantly increase the number of eutectic clusters while reducing the white mouth, so it can reduce the tendency of shrinkage and improve the compactness of castings....
