Embodiment

[0062] According to the above steps, Fe 2 o 3 -CaO-SiO 2 The ternary system binder phase is taken as an example, and the benchmark sample Fe 2 o 3 , CaO, SiO 2 The content ratio is 7:2:1, and the influence of the change of each component on the high temperature wettability of the binder phase is studied.

[0063] Table 1 Fe 2 o 3 Fe 2 o 3 -CaO-SiO 2 Variation of Contact Angle of Binder Phase in Ternary System

[0064]

[0065] Control system CaO and SiO 2 The mass ratio is constant, 2:1. It was found that with the system Fe 2 o 3 The content increases from 65wt.% to 85wt.%, and the complete liquid phase formation temperature of the system increases gradually, from 1304°C to 1467°C. According to the experimental requirements, the experimental temperature was selected as shown in Table 1. Fe 2 o 3 When the component content is 65wt.%, 70wt.%, 75wt.%, 80wt.%, 85wt.%, the corresponding contact angle measurements are 34°, 47°, 60°, 66°, 70°, with the Fe 2 o 3 ...

Abstract

The invention discloses an iron mine sintering binding phase high-temperature wettability measuring method. The method comprises the following steps: preparing a substrate; putting a binding phase sample onto the prepared substrate; warming a tube furnace in advance, and after the tube furnace rise to an appointed temperature, manually feeding the sample into the furnace at a constant speed with certain rate; shooting the melting and wetting conditions of the binding phase sample on the substrate in the experimental process, carrying out analysis on images in the experimental process through special software to obtain the contact angle of the binding phase sample on the substrate for representing the high-temperature wettability. The measurement of iron mine sintering binding phase high-temperature wettability can be completed through one horizontal tube furnace with a photographic device, and the method has the advantages of wide range of application, controllability for experimentalconditions, simple and quick operation, no fluctuation for experimental data, arrangement with actual sintering process and the like.

Description

technical field [0001] The invention belongs to the technical field of sintering in blast furnace ironmaking, and in particular relates to a method for measuring the high-temperature wettability of an iron ore sintering binder phase. Background technique [0002] my country's steel production industry is developing rapidly, and its steel production ranks first in the world all year round. Although the country is currently carrying out supply-side structural reforms and the steel industry has cut capacity, due to years of rapid development, my country's total steel production is huge. The output of steel has been stable at more than 800 million tons, and the output of crude steel in 2018 was 928.009 million tons. Iron and steel production is a large energy consumer in industrial production. Although the energy consumption of the sintering process only accounts for about 10% of the energy consumption of the iron and steel production process, in addition to the normal energy con...
