Hello everyone, I am the youngest girl in the factory. You see, these spheroidizing agents, inoculants, vermicularizing agents, covering agents, etc. for cast iron are all our products. This inoculation block is supplied to China Nonferrous Metals Jiangsu Branch. We have been cooperating since 2006, and almost every year we get five to six thousand tons of spheroidizing agent and inoculant from us. Pay attention to me, the youngest girl in the factory, I will take everyone to test the raw materials in the next issue

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 and...

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...

Today, let’s talk about metallic calcium. 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 knowledge, leave...

Do you still remember the rare earth raw materials from the previous auction? In the process of casting iron, the spheroidizing agent containing rare earth elements can remove impurities such as S and P in the casting, change the performance of the casting, and effectively improve the hardness or elongation of the casting. The rare earth in our factory uses lanthanum and cerium metal rare earth, which is refined from rare earth ore with less impurities. Some manufacturers use one-step rare earth silicon, or use cerium-rich slag auxiliary products to refine, such rare earth...

Today, let’s talk about scrap steel In fact, the quality of scrap steel is also the result of directly affecting the nodulizer. Let’s take a look.  The steel scraps in our factory are all A3 steel.  It can be seen to the naked eye that they do not contain rust and other impurities.  Such scrap steel has a single composition and melts well.  Because the spheroidizing agent is very taboo impurities, such as chromium, manganese, titanium, nickel, etc., these are de-spheroidizing elements. It can be said that our masters emphasized the single...

Today, let’s talk about the raw materials of spheroidizing agent The ferrosilicon used in our factory is all ferrosilicon above 75.  Ferrosilicon is often used in cast iron smelting to increase silicon after the furnace and partly incubate. It is one of the indispensable raw materials for steelmaking and cast iron. The ferrosilicon in our factory is strictly controlled at the source, and it is purchased directly from regular manufacturers in the ferrosilicon production area. For some bad ferrosilicon, they are all 70 or 65 ferrosilicon...

I am the youngest girl in the factory, Many netizens left messages on how to distinguish between good and bad nodulizers. How to prove that your spheroidizing agent is a good product. So, this week I will do some knowledge popularization. There are various elements in the spheroidizing agent.  The amount and distribution of these elements after interaction has a very important impact on the performance of the spheroidizing agent. According to our master's many years of experience, the raw materials of a good spheroidizing agent are very important.  Our...

I am the youngest girl in the factory. Today, I will take everyone to distinguish what is a good nodulizer. Some spheroidizing agents have low content of rare earth and magnesium, and castings produced with them will fail to reach the spheroidization grade, resulting in a series of defects such as a reduction in the elongation and high temperature resistance of the castings. Our cast iron spheroidizing agent has stable composition control, low MgO content, stable response, high Mg absorption rate, and safer use. Follow me, the youngest girl in...

I am the youngest girl in the factory. Today, I will show you our product analysis laboratory. This is our spectrometer specially used for product analysis. This is an instrument originally imported from the United States.  It can molecularly detect the various elements required in the product with very high precision. Each batch of our products can only be sent out after passing the test of this instrument, so we can guarantee the quality of the products and provide customers with high-quality products. Follow me, the youngest girl in the factory What else do...

Hello everyone, I am the youngest girl in the factory. This is our crushing and screening workshop, which is mainly used to crush products according to customer requirements. Look, these spheroidizing agents are packed in big bags, then they are hoisted up, put in the screening and crushing workshop,  and then crushed by the machine, screened with a sieve, and then the particle size is the customer's desired particle size. Follow me, the youngest girl in the factory, the next video, there are benefits!

I am the youngest girl in the factory.  In the previous issue, we mentioned our raw material scrap steel. Some netizens were curious that scrap steel could also become our raw material. Then our master really turned waste into treasure.  Today I will popularize our professional knowledge.  Go and see with me. This is our raw material scrap steel, when selecting scrap steel, the type of scrap steel must be determined according to the material and grade of the casting. In the production of scrap steel, it is important to match the scrap with the production castings. The...

I am the youngest girl in the factory. The last issue talked about covering agents. Many netizens leave messages, do you have any other products? Of course there is. Today I will show you another King Fried product in our factory——Strontium Silicon Inoculant Silicon strontium inoculant is especially important for the production of high-grade iron castings. It has the effect of delaying the diffusion of carbon and silicon and strengthening the inoculation of silicon. Therefore, it has a strong ability to resist inoculation decline and...

I am the youngest girl in the factory. In this issue, we will talk about the special covering agent for spheroidization. The covering agent we produce can greatly stabilize the spheroidization process and increase the recovery rate of Mg due to its pure composition, reasonable and moderate specific gravity, and strict particle size range. Spheroidizing agent plays an important role in cast iron, and the special covering agent for spheroidizing treatment is also an indispensable element. Because the covering agent facilitates the floating of gas...

I am the youngest girl in the factory. Today, let’s take a look at another King Fried product-nodulizer. This is the spheroidizing agent produced by the masters. Although some spheroidizing agents look no different from ours on the surface, the raw materials used are not up to standard, so they are unstable in use, and the spheroidization level is not up to the standard. The spheroidizing agent we produce has very strict requirements for the purchase of raw materials. Castings made with our spheroidizing agent have less impurities,...
