ホーム 会社 ミネラル&冶金 その他の鉱物&冶金 Henan Yuzi Industrial Co., Ltd

Henan Yuzi  Industrial Co., Ltd. mainly produces all kinds of abrasive materials, special refractory materials and metallurgical accessories.
For about *0 years development in  China , our factory has built  4 sets of the shaft kilns, producing high quality bauxite blocks for its own. and passes the ISO***1:***0 International Quality System Certification, and our products are exported to many countries and regions such as the United States, Russia, Japan and South Korea.
 
Our products:
1, Brown fused alumina

otherwise known as brown fused aluminum oxide (Al2O3), through an electric arc furnace process. Our brown fused aluminum oxide is made into many shapes and grit sizes ranging from macrogrits to microgrits and powders. Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity.
 it is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.
 YuZi€™s  brown fused alumina grains and powders are available in standard grit and powder sizes and they can also be made to individual specifications.
 
 2,White fused alumina

 
It is also called white fused aluminum oxide .
Fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.
YuZi€™s white fused alumina grains and powders are available in standard grit and powder sizes and they can also be made to individual specifications.
 
3, Mullite

Mullite is a good, low cost refractory ceramic with a nominal composition of 3Al2O3€2SiO2. The raw materials for mullite are easily obtainable and are reasonably priced. It has excellent high temperature properties with improved thermal shock and thermal stress resistance owing to the low thermal expansion, good strength and interlocking grain structure.
 
Key Mullite Properties:
1)Good thermal shock and stress resistance                                                                   
2)Low thermal conductivity                                                          
3)Good strength
4)Wear resistant
5)Usable to high temperatures
 
The Application of Mullite:
1)Gunning materials
2)Minerals for abrasion
3)Mouldable and Ramming Refractory Mixes
4)Recycled refractory minerals
5)Refractory castables
6)Refractory mineral blends
7)Refractory mortars
8)Refractory raw materials
9)Toll processing
YuZi€™s  mollite is  available in various particle sizes.
 
 
4,Magnesium Aluminum, Spinel

Magnesium aluminate spinel is a highly refractory material, with a melting point of ***5„ƒ. Table 1 shows a comparison of the density, thermal expansion coefficient and thermal conductivity of the end-members (MgO, Al2O3) compared to the spinel phase. The differences between these phases in thermal expansion are responsible, in part, for the superior thermal shock resistance of spinel. The decrease in density, respectively increase in specific volume as spinel forms from the end-members needs to be considered for technical applications, e.g. in castables, where spinel is formed in-situ from MgO and Al2O3 components. These effects and their influence on performance will be discussed in more detail in a later section.
Spinel additions remarkably increase the performance of alumina refractories and contribute to more cost effective lining concepts. Typical spinel applications are steel ladle linings, impact pads, purging cones and well blocks, nozzles, wears and dams, lances, and slide gates.
 
 
 
 
 
5,Kaolin

We supply high quality Kaolin ,processed in an ISO ***0:***1 certified plant that is well equipped with most sophisticated laboratory for stringent quality control. Kaolin is available in various sizes and grades to match the several requirements of the clients. Perfect for different industrial applications.
                                      
Major features of kaolin:
1)relatively high plasticity which enables good workability in raw state
2)easy deflocculation by available deflocculants (addition of 0.1% Na2CO3)
3)high content of Al2O3 and low content of alkalis provides high stability in fire
 
The Application of Kaolin:
1)Refractories
2)Ceramics
3)porcelain tableware and decorative articles
4)Paint
5)Paper
6)fillers and binders
 
6, Calcium aluminate (Premelted calcium aluminates residue)

It is mainly used for separating the impurity elements such as sulfur and oxygen in ladle refining of LF furnace, open hearth furnace and the converter furnace, and it can reduce the content of harmful elements and impurities, which is applicable for general carbon steel, high carbon steel, high and low alloy steel. Its applications have already been mature in some foreign countries, such as South Korea, Japan, the United States and the developed European countries.
Over the years, our Company has been engaged in the research and development of Calcium aluminate. In recent years, based on technical support of Luoyang Institute of Refractories, referring to various formulations of different manufacturers at home and abroad, and adopting a variety of comments and suggestions of the users, our factory has made impressive performances in the whole production process from smelting, manufacturing to using of the fused calcium aluminate.
 
 Calcium aluminate of our company takes the advantages of uniform chemical compositions, low melting point, high melting speed, and short smelting time. And it has no fluoride and doesn€™t erode furnace lining and ladle, and it is compact, non-absorbent, and easy to storage as well. As Calcium aluminate has stable phase and fast dust-reducing speed, we can reduce the pollution of steel mill and make the refining technique mature. Without other impurities such as hydrogen, nitrogen, carbon, it can help to improve the quality of steel. Tested by the users, the stability of our Calcium aluminate products is long-tested, and it avoids many instable phenomena brought by the middle and lower end products such as sintering materials, and cupola furnace products.
 
In addition, we can organize mass production according to the different chemical composition requirements of the customers and keep confidential for them.
Usage of the calcium aluminate:
1)If deoxidation is the main process, you shall add it to the capsule bottom directly before tapping. The amount of adding depends on the carbon content in the molten steel, and is generally allocated with steel of **6kg/***0kg. One quarter before tapping, you shall add ferromanganese, ferrosilicon and aluminum with the general amount. After tapping, you shall add manganese, ferrosilicon with general amount to the carbon steel, without adding any other alloys and aluminum feed line, and the steel ladle only needs to be refined by Argon blowing process. If you use the product to deoxidize, the increasing carbon agent (SiC) can be reduced by ****0% in volume.
2) If desulfurization is the main process, you shall add it to the capsule bottom with one-third of usage, but it must be at the capsule bottom of the steel pounding. With the outflow of molten steel, you shall add two-thirds of it. And the steel usage of **8kg/***0kg is depended on the original sulfur content in steel and the using results.
