Problems solved by technology

[0004] However, what is measured by using the quenched glass state is only the spectrum of a certain non-steady state. Even the same amorphous sample will show structural differences due to different cooling rates, so the structure of the quenched glass state cannot be transmitted correctly.

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with specific embodiments.

[0033] The method for rapidly melting slag materials to form a liquid film with uniform temperature is characterized in that it comprises the following steps:

[0034] 1) Mix the powder of slag material with alcohol evenly to form a paste-like slag as a sample;

[0035] 2) Heat the sample through a closed heating device. The heating device is a heater composed of a thermocouple. The head of the thermocouple is folded into a W shape. Take the sample and place it in the W head area of ​​the thermocouple, and close the heating device;

[0036] 3) Fix the two ends of the thermocouple on the two terminals of the electrode seat respectively, and then connect the two terminals to the temperature control system through cables;

[0037] 4) Start the temperature control system to heat up the thermocouple, so that the sample absorbs heat energy, and finally forms a molten l...

Abstract

The invention provides a method and device for rapidly melting slag-like materials to form a uniform temperature liquid film. The method adopts a platinum-rhodium thermocouple for temperature measurement and simultaneously serves as a heating element to heat and melt a sample whose effective component is slag-like material to form a uniform temperature, The liquid film with an area of ​​about 0.5×1mm2 makes it possible to continuously detect the microstructure information of metallurgical slag materials such as high-temperature molten blast furnace slag, steelmaking refining slag, and mold slag on-line. Simultaneously, the present invention also provides a device for rapid melting to form a liquid slag film with uniform temperature. The position of the thermocouple can be adjusted by a micrometer so that the slag sample liquid film is in the center of the spherical cavity. Under the combined effect of reflection and the heat insulation of the shell interlayer, the temperature of the molten liquid film at the center of the spherical cavity is made uniform, and the detection rays are introduced from the incident window and projected from the exit window, so that the detection of the molten liquid film can be realized. scan probe.

Description

technical field [0001] The invention relates to the technical field of melting and detection of metallurgical slag materials, especially the technical field of melting and detection of blast furnace slag, steelmaking and refining slag, mold slag and other slag materials, and specifically relates to the rapid formation of slag materials into a molten state with uniform temperature Liquid film method and apparatus. Background technique [0002] In the pyrometallurgical process, molten slag such as blast furnace slag, steelmaking refining slag, mold slag and other slag materials play an important role, mainly by controlling the chemical composition, temperature and The physical and chemical properties of the slag are realized, and the chemical composition and microstructure of the slag directly affect the physical and chemical properties of the high-temperature slag. Research on the basis of the microscopic bonding structure between the various substances that make up the slag...
