Method for detecting maximum thickness of bituminous coal gelatinous layer and application

The invention discloses a bituminous coal gelatinous layer maximum thickness detection method and application, and relates to the technical field of iron and steel smelting. Comprising the steps that a coal sample is heated, the upper layer height and the lower layer height of the coal sample are detected through a probe in the temperature rising process, and the difference between the upper layer height and the lower layer height is the maximum thickness detection value of the bituminous coal gelatinous layer. And correction is carried out by adopting a calculation formula according to the maximum thickness detection value of the bituminous coal gelatinous layer, the maximum thickness of the bituminous coal gelatinous layer is associated with the particle size of the coal, the actual maximum thickness of the bituminous coal gelatinous layer is obtained through correction by finding the relationship between the maximum thickness of the bituminous coal gelatinous layer and the particle size of the coal, and th
