Cleaning of Crystallization Wheel

Since the working temperature of the crystallization wheel is 50-60 ° C., after long-term use, a thick layer of scale will accumulate on the inner wall, which will not only affect the heat exchange and cause the ingot quality to be unstable, but also cause the crystallization wheel to deform due to uneven heat conduction. Therefore, the crystallization wheel should be cleaned regularly with dilute acid solution to ensure that the crystallization wheel has good thermal conductivity, and more importantly, measures should be taken to clean the water source. Sodium ion exchangers are generally used to reduce the Ca ion content in the water, thereby reducing the scale of the crystallization wheel. In recent years, many manufacturers have installed a Canadian-made Dick scale remover on the cooling water inlet pipe. The device is compact, weighs less than 3kg, is easy to install and use, and has good results.
