The equipment is used to test the resistance of refractories to co disintegration when exposed to co atmosphere under specific environment and temperature. It is mainly developed according to ASTM c288 "test method for determining the disintegration of refractories in carbon monoxide at one atmospheric pressure". The control part is an intelligent controller, which realizes the automatic control of temperature rise, heat preservation, test data acquisition, printing, shutdown, carbon monoxide leakage alarm and accident alarm. The operation is simple and convenient, and the safety facilities are complete.
