CMT furnace sliding rail tube furnace according to the setting requirements to achieve automatic left and right movement, movement speed can be manually adjusted, also can change the temperature field at any time and rapid cooling. After the furnace warms up to the set temperature on one side, it moves directly to the sample placement area on the other side, so as to realize rapid warming with the speed up to 140℃/min. After the completion of sintering, the furnace moves away from the sample placement area, so as to realize rapid cooling of the sample. The cooling rate of 300℃~1200℃ can reach 200℃ ~ 50℃/min.
