Products we offer

Metal-bonded plates series

Tabular corundum, metal aluminum powder, silicon carbide, etc. are used as the main raw materials, and appropriate amount of boron carbide powder and other additives are added to improve the anti-oxidation performance. According to user needs, use silicon modified resin or phenolic resin as binder with high solid content, high carbon residue and good oxidation resistance. After molding, according to the requirements of use, the non-burning, nitriding and low-temperature firing processes are respectively adopted.
It has the advantages of high bulk density, low porosity, high thermal strength, strong thermal shock resistance and corrosion resistance, and good oxidation resistance. Due to the characteristics of short production cycle, energy saving and environmental protection, the scope of application is wider.

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
Read More
We improved the bricks formula and specification accoridng to our experience, the final using performance doubled compared with their previous specification.

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.
