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.
