Surface tension estimation method for coal inert structure, surface tension estimation method for coal, and coke manufacturing method

摘要

A method for easily estimating the surface tension of coal is provided. It is a method for estimating the surface tension of coal, and shows the relationship between the surface tension of coal and the total amount of inertia from the surface tension of the inertial structure of coal estimated based on the degree of coalification and the surface tension of the molten structure of coal. A relational expression (second relational expression) is calculated, the total amount of inertia of the coal for which the surface tension is estimated is measured, and the surface tension of the coal is calculated using the measured total amount of inertia and the relational expression. ..
