Heater Protection Tube

Owing to our rich industrial experience and expertise, we are engaged in distributing, exporting and supplying a wide range of Heater Protection Tube in Zibo, Shandong Sheng, China. Temperature control of molten metal is the sky factor for good casting . For optimum pouring temperature of molten metal , heater will be used for keeping temperature steady. Silicon nitride heater production tubes will not only protect the heater without erosion but also make rapid and uniform heating of molten metal during casting.
