The invention relates to an experiment device for testing a softening and dropping point of a sinter. The device is composed of a large current transformer, a furnace body fixing column, a tray, a furnace body adjusting frame, a rotary column, a pressurized gas cylinder, a displacement sensor, a furnace top sealing furnace cover, a pressurized graphite compression strut, an anti-radiation graphite cover, a molybdenum disilicide heater, a graphite crucible, a high pure graphite sleeve, a sealed alundum tube, a pinhole camera, an air inlet channel fixing sleeve, a dropping crucible weighing device, a dropping crucible device, a furnace body chassis, furnace body castors, a heating furnace body, a cantilever beam, a sample temperature thermocouple, a alumina hollow ball member, a furnace temperature control thermocouple, a rotary column circular sleeve, a pressurized gas cylinder pipeline and a pressure transmitter. The large current transformer is adopted to supply power for the molybdenum disilicide heater; the pinhole camera is used to observe a dropping process of high temperature liquid slag iron; the dropping crucible weighing device is arranged; the crucible is assembled and disassembled in a manner of laterally opening the door; and the position of the heating furnace body is adjusted by the furnace body adjusting frame, so that the device is flexible, accurate and convenient for operations.
