The equipment is easy to operate and has high work efficiency. The swinging, feeding, positioning, impact, and release are all controlled by computers, using the principle of thermal balance and cyclic stirring to achieve automatic and uniform cooling and constant temperature of the sample. The temperature adjustment is all electrically controlled, equipped with a dedicated sample feeding device for automatic feeding and automatic end face positioning of the sample, ensuring that the impact time from the sample being taken out of the furnace is not more than 2 seconds, meeting the requirements of the low-temperature Charpy impact test method for metals. It is particularly suitable for laboratories that continuously conduct impact tests and metallurgical, mechanical manufacturing and other industries that conduct a large number of impact tests.
