 Refractory of acidic lining of CF4AL channel electric inductio furnace |
|
 Description and main technical information for Refractory of acidic lining of CF4AL channel electric inductio furnace: |
| |
 |
| |
The product is widely applicable for the lining of channel electric induction furnace for smelting ferrous and non-ferrous metal. |
| |
 |
|
|
|
In order to satisfy the wide demand in domestic markets for high-quality refractory materials, we increase the use lifetime of lining of electric induction furnace, economizing the energy source, and reducing the cost of casting. The product is based on quartz sand and added a small quantity of anchoring agent and mineralizing agent, then mixed with various particle-sized grading. At present, the response about the product use from customers is very well, and the product stands the leading rank in domestic markets as well.
