Experiment device for testing softening and dropping point of sinter

Abstract

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.

Description

technical field [0001] The invention relates to a novel iron ore detection test device, in particular to a sinter softening drop point test test device. Background technique [0002] In the test experiment of physical and chemical properties of iron-making raw materials, the simulated blast furnace conditions are very important for the actual test of iron ore high-temperature load reduction refractory dripping performance. During the test, the ore sample needs to be heated under load first, and then heated in the reaction furnace. Introduce reducing gas, specifically measure the high-temperature properties such as the initial softening, melting and dripping of iron-containing raw materials, determine the process of dripping, and the melting temperature of slag iron and other related indicators, and observe the slag iron dripping through the camera It has become an important means to detect the high-temperature smelting performance of sinter, pellet and lump ore. However, in...
