Magnesium carbon brick recommended model selection

Magnesia carbon bricks for EAF

  • Application site: MgO-C bricks for EAF side wall

  • Select Model:LY-S-NSA-11OXMA

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 quantity of carbon, introduced below.

Feature of S-LY

  • 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.

Technical data of side wall refractories:

our customers worldwide


The MgO-C bricks which used in EAF has a good performance in 75 furnaces, we are so satificated with the using performance of the bricks from LMM YOTAI
Ukrainian customers
We improved the bricks formula and specification accoridng to our experience, the final using performance doubled compared with their previous specification.
Egypt A customers
In the ladle we have been using high alumina bricks with a performance of 50 heats. After the improved design of LMM YOTAI engineers, we use magnesia carbon bricks instead of high alumina bricks, and the performance reaches 60 furnaces and is still running.
