The equipment is composed of heating furnace, loading mechanism, automatic injection mechanism and control system, with compact structure, novel shape and convenient sample loading operation. The heating furnace has good heat preservation performance, energy saving and high efficiency. The loading part adopts the parallel bar type vertical loading mechanism with patent technology, which is a kind of non gap loading mechanism. It adopts frequency conversion speed regulation, and can completely carry out constant rate loading according to different loading rates. The injection mechanism is accurate and easy to operate. It has the characteristics of wide test range, high precision, less misoperation, high efficiency, stable and reliable operation. The six samples can be operated automatically within 15 minutes, which is 15 minutes shorter than that of frame type bending compression samples, which can meet the loading rate requirements of the standard in the whole range. (slide type and mechanical switch type are easy to miss sample position, resulting in inaccurate sample position)

The equipment is used to measure the high temperature bending strength of refractories. The equipment is manufactured in strict accordance with the requirements of international standards iso5013, iso5014 and national standard GB / t3002 "test method for flexural strength at high temperature". It is composed of heating furnace, loading mechanism, automatic injection mechanism and control system. IPC industrial computer is used for automatic control, which has friendly interface, high precision of temperature control and loading, dynamic real-time display of temperature time and pressure time curves, and the original data can be converted into excel storage format, and the test report can be read and printed at any time. The bending strength of the material can be tested in nitrogen, argon, air and carbon.
