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.

Quality Guarantee

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.
