Sunrise, a brand under Zhengzhou Tianyang Refractory Materials Co., Ltd., presents high - density dense zirconium blocks designed for high thermal stress molten pool stone plugging. These blocks are a reliable choice for various high - stress applications. They feature an extremely dense crystal structure and a large bulk density, enabling them to withstand high - temperature environments. With excellent mechanical strength at both room and high temperatures, good wear resistance and thermal shock stability, minimal reheating shrinkage and high - temperature creep, they also have high chemical stability and strong resistance to alkaline medium corrosion. The products are made of high - quality materials with strict specification control and are certified by the ISO9001 international quality system. We also offer comprehensive after - sales support, including quality assurance, 24/7 technical support, and delivery tracking.

1. Extremely dense crystal structure and large bulk density. 2. Excellent mechanical strength at room and high temperatures. 3. Good wear resistance and thermal shock stability. 4.

These high - density dense zirconium blocks are mainly used in the glass - contact parts with high thermal stress requirements in alkali - free glass fiber furnaces, such as molten pool inlaid stones. They are also suitable for channel blocks, casing blocks, and key parts in low - alkali borosilicate glass furnaces. They are suitable for glass manufacturing industries and related enterprises around the world that have high requirements for high - temperature and corrosion - resistant materials.
