Metallurgical pellet bentonite
Features
Bentonite for metallurgical pellets is a kind of bentonite, which is also called porphyry or bentonite. Bentonite (Bentonite) is an aqueous clay ore dominated by montmorillonite, with the molecular formula of Nax(H2O)4 (AI2-xMg0.83) Si4O10) (OH)2, because of its special properties. Such as: benting, adhesion, adsorption, catalysis, thixotropic, suspension and cation exchange, so it is widely used in various industrial fields. Foreign countries have been applied in more than 100 departments in 24 fields of industrial and agricultural production, with more than 300 products, so people call it "universal soil".
In the metallurgical industry, bentonite is also widely used, because of its high stability and adhesion at high temperature, it has become an irreplaceable cheap raw material, greatly improving the quality of the metallurgical industry.
The main characteristics of Yiheng metallurgical pellet bentonite:
(1) Significantly improve the strength of green balls and expand the roasting area.
(2) The material layer is well breathable.
(3) Good desulfurization effect.
(4) The addition amount is low to improve the grade of pellets.
(5) Reduce costs and significantly improve the economic benefits of steel enterprises.
Heng Diamond Pellet Bentonite has been cooperated with dozens of large group companies such as China National Petroleum Pipeline Engineering Co., Ltd., China National Offshore Oil Corporation Limited, CNOOC Development and Logistics Co., Ltd., Tianjin District, Liaohe Oilfield Technology Co., Ltd., CNOOC Energy Development Co., Ltd. and so on.
Classification and main characteristics
The application of pellet bentonite in the metallurgical industry is very common, but the unit consumption varies greatly. Of course, this has a certain relationship with the taste of refined iron powder in each steel mill; What's more, the quality of pellet soil varies greatly. Here is a summary of the three common metallurgical pellets bentonite on the market.
The first type: ordinary calcium clay: This bentonite clay is basically through a very simple production process. After the raw ore is mined, after drying or drying, it is directly milled with Raymond. Basically no additives are added. Steel mills using this pellet bentonite are mainly concentrated in Hebei Province, and the unit consumption is high.
The second type: sodium pellet bentonite: many people call sodium ductile bentonite. It is sodified by the raw ore, then dried or dried, and then milled with a Raymond machine.Compared with the first type of pellet bentonite, there is an additional sodium process. This kind of soil is used more in Shandong, Jiangsu, Fujian and other provinces.
The third type: composite pellet bentonite, which is based on the second sodium-based bentonite by adding a certain amount of cellulose or sodium carboxymethyl cellulose to improve the viscosity. This bentonite clay has a high cost, but the unit consumption during use is very small, and the finished pellets made are of high taste. At present, smelting enterprises in Shanxi Province prefer this kind of pellet bentonite.
Because the use habits of steel mills in different regions are different, the types of metallurgical pellet bentonite selected are also different. Metallurgical pellet manufacturers should pay attention to the selection of bentonite manufacturers that can produce high-quality products when choosing bentonite suppliers, which can benefit the quality of the pellets and reduce production costs.
