LMM YOTAI established in 2007. Our production technology comes from Japanese Yotai. As an experienced and international player in the refractories industry. We have succeeded in expanding both the breadth of its product range and the depth of its services. From raw material selection, refractory portofio & optimization, installation & services & recycle of used refractories on site to further reduce client’s Opex in refractory consumption per ton steel output, meanwhile improve product quality of client.


  • Good high temperature resistance
  • Strong anti-slag penetration resistance
  • Resistance to thermal shock
  • High Corrosion resistance to slag
  • Non-Wettability to molten slag
  • Increases lifespan of the ladle.
  • Low thermal expansion

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

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.
