The equipment is used to measure the exudation temperature of glass phase in casting refractories. The equipment is manufactured in accordance with the requirements of national standard JC / T 805 test method for glass phase exudation temperature in refractories for glass furnace. IPC industrial computer is used for automatic control, with high temperature control precision (expert fuzzy control algorithm is applied), and test results are recorded automatically. The temperature time curve can be drawn to show the sample image and the exudation temperature of the glass phase in the sample.
