Side wall refractories for EAF : LY-S-NSA-110XMA
Especially S-NSA has developed as especially for side wall hot spots in bricks for electric arc furnace. In order to meet variety of needs, YOTAI supplies plenty of variations by replacing grade of raw materials or carbon content, introduced below.
Feature of LY-S-NSA
- Base of carbon content is set as 20% to take advantage of carbon characteristics.
- Varieties of brands are developed by corporate with different grades of raw materials and carbon contents.
- High durability is carried out for hot spots by adopting high purity materials and dense construction.
- Bricks used for except hot spots are took into account of balance and durability and cost by replacing grade of materials.
- Low carbon type supports for oxidization damage by oxidization slag.
