Refractory brick Process:
Raw material to factory→ checkout→ burdening→stirring→mixing→taking out the raw material→transfer
→enter into mould→press machine extrusion→going out the mould→stoving→going into the furnace→firing
→stopping burn→cooling→open the furnace door→going out the furnace→checkout→packing→qualified product
→putting in storage→sale
