PURPOSE:To obtain a sample which reflects faithfully the distribution characteristic of the packed layer of the piled charging raw material layer in a furnace by inserting a hollow cylindrical body which is opened by a sharp pointed end edge through the opening provided in the furnace wall. CONSTITUTION:A hollow cylindrical body 1 which is forcibly penetrated through the opening in the furnace wall, into the packed layer of a piled charging raw material and a measuring means which measures the margin for insertion of the body 1 into the furnace and the length at which the piled charging raw material is introduced into the body 1 are provided. The body 1 which is opened by a sharp pointed end edge is inserted into the furnace and the packed layer of the piled charging raw material in the furnace is introduced into the body 1. The margin for insertion of the body 1 into the furnace as well as the length at which the piled charging raw material is introduced into the body 1 are measured. The position of the drawn sample is thus securely detected and the operation of the blast furnace is effectively controlled. |
