Recently, officials and workers of the Jangsan Mine succeeded in producing high-quality chamotte refractory bricks with a large tunnel kiln.
The new production process of high-quality chamotte refractory bricks is run with locally available technology, facilities and raw materials 100 percent.
High-grade clay produced at the mine is reportedly used for the production of these bricks.
The technical group of the mine laid the foundations for the production of high-quality chamotte refractory bricks by properly solving the difficult technical problems including the boost of technical performance of the gas generator and establishment of a magnetic cobbing process that does not use electric power. They thus opened up prospects for increasing the production of these bricks.
Case studies of its introduction into several units including the Hwanghae Iron and Steel Complex show that the repair cycle of kilns has lengthened markedly.
