Production process of silica brick, quartz fire brick

1)Raw material to factory→checkout→burdening→stirring→mixing→taking out the raw material,
2)Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment.
2.Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.Inspection and Control of incoming raw materials: according to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of weight .
3.Quality audit by quality management: inspection of product standardization of quality of each product by process control and experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of silica brick, quartz fire brick again in factory.
