5, Manufacturing Process of Refractories

01. Crushing
In this stage massive raw materials which have been stored, are ground and classified into proper sizes, making them easier to shape.

02. Mixing
The prescribed size of ground raw material is weighed and mixed into a designated amount of water and forming agent.

03. Shaping
The mixture is then poured into a mold to form shapes, and the pressure is high.

04. Drying
In this stage water is removed from the shaped bricks. This helps preventing the bricks from deforming or cracking which may result due to the rapid evaporation

05. Firing
This is the most crucial process in refractory manufacturing. The modeled bricks are fired at high temperature to complete their thermochemical reaction so that they do not deform.

06. Inspection
The bricks' physical and chemical properties are inspected very carefully by rigid quality management procedures.

07. Packing shipment
We guarantee efficient delivery every time.
