Production process of silica brick for coke kiln
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 again in factory.
