Advices of using the element1). In order to keep furnace temperature and the charges uniform of each element, before installation resistance distribution must be carried.2). As the element is very brittle ,be careful while install and maintain to avoid any damage.3). when start to operate the furnace ,raise voltage slowly and gradually,never give full load at one time.When you inquiry, pls tell us the following data:a). Outer diameter (OD)b). Length of Hot zone (HZ)c). Length of Overall (OL)d).
