Raw Material Calciner (Ceramics)
げんりょうかしょうこう
Industry & Occupation
Classification
Summary
Raw material calciners handle the compounding of raw materials for porcelain, tiles, etc., and the firing process using kilns, maintaining product quality as a manufacturing role.
Description
Raw material calciners accurately weigh and mix raw materials such as clay and glaze, and crush and knead them using grinders or mills. They receive the mixture from forming workers and load it into the kiln according to the firing schedule. They set the temperature profile and monitor and record temperatures using control devices during firing. After firing, they inspect product appearance and dimensions, sorting out defective items. They also handle kiln cleaning, inspection, daily maintenance, and thoroughly manage safety and quality.
Future Outlook
Japan's domestic ceramics industry faces fierce competition from overseas products, with employment remaining flat or declining. The introduction of automation and labor-saving technologies will change skill requirements, but demand for specialized technicians is expected to be maintained at a certain level.
