LMM TOTAI offer a complete product and service portfolio for all steelmaking processes.
From basic and non-basic bricks and mixes, slide gate plates, isostatic products and prefab components to special machinery, mechanisms and repair systems.
The environments of transition zone, burning zone and cooling zone in cement rotary kiln are severe due to high temperature from burning clinker and erosion of K,Na,Cl,S.
The upsize of rotary kiln and usage in waste disposal make the condition of using refractories even harsher.
LMM Yotai group developed MgO-Cr203 series, MgO-Al203 Spinel series and non-chrome series bricks for cement rotary Kin, which have achieved remarkable results.
We occupy top shares in Japan refractory market, and have expanded greatly in China market as well.
Refractory for Transition of Rotary Kile
Cold Crushing Strength
Refractoriness Under Load T2
Thermal Shock Resistance (1100℃-water)
For environmental conservation, non-chrome bricks including MgO-Al2O3, spinel, Hercynite,MgO-Al2O3.-ZrO2 were developed and are widly used in transition zone, cooling zone and sintering zone to replace MgO-Cr2O3 brick
Refractory brick production process
The manufacturing of refractory brick includes six general steps: mining and storage of raw materials, preparing raw materials, forming the brick, drying, firing and cooling, de-hacking, and storing finished products.
The company ownis highly advanced automatic hydraulic press and tunnel kins capable of standing up ot 1850 celcius degrees. We manufacture various high-quality refractory products according to the clients’ needs, and to ensure the stability and account ability of the quality, we track and control the full manufaturing process through a variety of physical and chemical analysis.
Our company inherets the advanced technology, management experience and quality control from YOTAl. We have formed a comprehensive, effective and standarized management system with an excellent management team.
LMMYOTAI group devotes to the manufacture and research of refractory, design and construction of furnaces, while occupies top shares in cement rotary kiln, nonferrous metals, waste disposal and glass furnace in Japan.
