VA8008 HIGH TEMP. ROLLER WITH SUPER THERMAL SHOCK RESITANCE
Maximum service temperature up to 1320°C, adopting the lastest NANO technology and special raw materials in new composition, the VA8008 has the excelent performence to the thermal shock due to its high density, strong rigidity and good toughness! Which make the VA8008 can be replaced at anytime during the production in the firing zone of the kiln . You could witness the amazing of high multiple utilization after using our VA8008!
- With super strong thermal shock resitance;
- Can be repull out and reput inside during production without low down the temperation;
- Annual consumption (=cost) could be reduceed more than 60%.
