Problems solved by technology

However, for the convenience of research, the above research process usually regards titanium-containing slag as a Newtonian fluid. In fact, because of the existence of TiC, TiN and its solid solution Ti(C,N), the titanium-containing slag behaves as a non-Newtonian fluid. Unfortunately, Due to the limitation of high temperature and other conditions, there are very few reports on the non-Newtonian properties of titanium-containing slag

Abstract

A device and method for observing the rod-climbing phenomenon of titanium-containing slag belongs to the field of non-Newtonian properties of titanium-containing slag. The device includes an X-ray generating device, an X-ray image intensifier, a video camera, a high temperature resistance furnace, a rheometer, a data acquisition system, a lead protection room and a crucible. The method is as follows: mix materials to make slag samples; configure the instrument and heat up to the specified temperature; turn on the X-ray switch, adjust the exposure voltage until the picture is clear, and observe the change of the slag liquid level in the crucible at different shear rates; Changes of the slag liquid level in the crucible under different shear rates. The device of the present invention adopts X-rays to transmit in the lateral direction, and monitors the change of the slag liquid level in real time; allows the X-rays to pass through the high-temperature resistance furnace and the crucible with low loss, and at the same time ensures the sealing and heat preservation of the high-temperature resistance furnace; the lead protection room adopted can effectively prevent X-ray radiation, protect the staff. The method of the invention verifies whether the titanium-containing slag has the rod-climbing phenomenon by observing the change of the liquid level of the slag.

Description

technical field [0001] The invention belongs to the field of non-Newtonian properties of titanium-containing slag, in particular to a device and method for observing the phenomenon of titanium-containing slag climbing rods. Background technique [0002] When the blast furnace smelts vanadium-titanium magnetite, the TiO2 in the slag is reduced to TiC (3140±90°C), TiN (2950±50°C) and its solid solution Ti(C, N), which brings a series of technical problems to the blast furnace production , such as slag thickening, large iron loss, foamy slag, etc. In recent years, scholars have done a series of research on the physical and chemical properties of titanium-containing slag, such as the easy thickening of titanium-containing slag, foamy slag, etc., and have achieved a series of research results. However, for the convenience of research, the above research process usually regards titanium-containing slag as a Newtonian fluid. In fact, because of the existence of TiC, TiN and its so...
