Coke oven, a type of industrial furnace usually built of refractory bricks (including clay bricks, silica bricks, heat insulation bricks, etc.) and refractory clay blocks for carbonizing coal to produce coke. The coke oven is the primary thermal equipment used in coke production. Coke oven consists of carbonization chamber, combustion chamber, regenerator, slope area, foundation, flue, etc. and is connected by flue and smoke window.
Zibo Runjin Refractories Co., ltd. has been exporting refractory clay bricks and silicon bricks for repairing coke ovens to Japan since 2005. The products are primarily used in the carbonization chamber, regenerator, slope area, and flue. Especially the large fire clay checker brick has been continuously supplied to Japan market for nearly 20 years.
The metallurgical and steel production technologies in Japan are at the world-leading level, and their coke-making process technology is also world-class. As a result, stringent technical specifications and appearance quality standards apply to refractory bricks in Japan. Over the past 29 years, our company has consistently adhered to stringent production standards and continuously enhanced product quality. And until now through the adoption of robotic production lines and natural gas fuel, we have significantly improved product quality and achieved customer recognition.
