Refractory Balls

Refractory balls are spherical refractory products with refractory materials as the main component, which have good refractory performance and thermal shock resistance. They are widely used in furnaces in industries such as steel, glass, ceramics, and cement. · Good refractory performance: high refractoriness, suitable for high temperature environments. · Good thermal shock resistance: able to withstand rapid changes in temperature and reduce thermal shock damage. · High strength: has high mechanical strength and can withstand large loads.
