Method for rapidly measuring steel slag residue water content

Abstract

The invention discloses a method for rapidly measuring the steel slag residue water content. To-be-measured steel slag is placed in a material collecting disc, and the material collecting disc is placed on a platform scale in a drying oven; the drying temperature is set, and the mass mi displayed by the platform scale is read at intervals along with the drying process; when the reading of the platform scale does not change any longer, the mass m0 of the completely dried steel slag and the material collecting disc is obtained; the steel slag is poured out, and the net mass m of the material collecting disc is weighed; a relation curve graph of the steel slag residue water content and the time is drawn at the set drying temperature; and the to-be-measure steel slag is subjected to drying treatment at the set temperature in the construction process, the drying time is determined according to the relation curve graph, and the steel slag with the target residue water content is obtained. The residue water content variation curve of the steel slag can be rapidly obtained at the set construction drying temperature, and the steel slag with the accurate water content can be obtained by controlling the drying time.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a method for quickly measuring the residual moisture content of steel slag. Background technique [0002] With the continuous deepening of reform and opening up and the improvement of the country's overall economic strength, the level of urbanization has been significantly improved. The development of the national economy has a huge demand for steel. At the same time, steel slag is the main solid waste in the ironmaking industry. Its output is also very large. According to the data, the comprehensive utilization rate of steel slag is not high because the total amount is too large. This directly leads to an increase in the accumulation of steel slag year by year. However, from an overall analysis, there is still a lot of room for improvement in my country's steel slag treatment and processing technology, and the comprehensive utilization rate of steel slag is still belo...

AI Technical Summary

Problems solved by technology

Moreover, steel slag also pollutes the surrounding soil and rivers to a certain extent, thus affecting people's work and life. Therefore, the problem of effective treatment and utilization of steel slag is imminent

Moreover, due to the differences in raw materials used by iron and steel enterprises in various places, as well as differences in processing equipment and treatment methods, this leads to certain differences in the chemical composition and physical properties of steel slag produced by various enterprises. The attention and utilization are also different, and finally formed a relatively unified and effective treatment equipment and technology for all steel slag
