Description

Technical Field

[0001] This utility model belongs to the field of glass phase content detection technology of refractory materials, and specifically relates to an auxiliary detection device for glass phase content of refractory materials. Background Technology

[0002] Refractory materials are a class of inorganic non-metallic materials capable of withstanding high temperatures (typically exceeding 1000°C) and maintaining physical and chemical stability under their working conditions. They are widely used in the lining of high-temperature equipment in industries such as metallurgy, building materials, chemicals, and power. Based on chemical composition, refractory materials can be classified into siliceous, aluminosilicate, magnesia, and carbon composite types; according to manufacturing processes, they can be classified into shaped and unshaped materials. Their performance indicators include refractoriness, thermal shock resistance, corrosion resistance, and mechanical strength.

[0003] The glassy phase is an amorphous substance formed by the cooling of molten metal at high temperatures in refractory materials, typically composed of low-melting-point oxides (such as SiO2, Na2O, K2O, etc.). An appropriate amount of glassy phase (5%-15%) can fill intergranular gaps, promote sintering, and increase the material's density. However, excessively high glassy phase content can lead to negative consequences such as decreased high-temperature strength, deteriorated thermal shock resistance, increased susceptibility to chemical attack, and reduced volume stability in refractory materials.

[0004] The common process for detecting the glass phase content of refractory materials involves sample preparation, acid treatment, filtration, washing, drying, weighing, and then calculating the content. Each step requires the participation of staff, resulting in a low degree of automation and hindering the improvement of production efficiency. Utility Model Content

The component 23 is installed in the through hole. The stirring component 23 includes a stirring shaft 231. The bottom of the stirring shaft 231 is provided with stirring blades 232.

When the weight reaches a constant value, the control terminal controls hot air valve 61 and heating plate 12 to stop heating.
