Abstract

The invention discloses a quantitative sampling device and sampling method of the blast furnace slag. The quantitative sampling device comprises a quantitative container and a cooling device. The quantitative container is disposed in the middle of a base. The cooling device has a cavity structure with the hollow inside; and cooling liquid is arranged inside the cooling device. Molten blast furnaceslag is installed in the quantitative container; and the cooling device is arranged at the upper part of the quantitative container, so that the molten blast furnace slag in the quantitative container is cooled to be at a room temperature. According to the invention, the sampling device having a simple structure is operated conveniently. The used quantitative container has the certain capacity torealize quantitative sample. Besides, with the cooling device as a unique independent component, the flexibility of the cooling operation of the blast furnace slag is improved, so that the blast furnace slag is cooled rapidly to obtain a blast furnace slag sample with the uniform crystal composition.

Description

technical field [0001] The invention relates to the technical field of blast furnace slag sampling, in particular to a blast furnace slag quantitative sampling device and a sampling method. Background technique [0002] In the field of metallurgical technology, in order to detect the chemical composition of blast furnace slag, it is necessary to collect blast furnace slag samples from the slag ditch of the blast furnace. [0003] At present, blast furnace slag sampling in the iron and steel industry generally uses a steel ladle to scoop it from the blast furnace slag ditch, and knocks it out after natural cooling in the steel ladle. Due to the large amount of sampling, the crystallization speed of different components of the high-temperature molten blast furnace slag is quite different during the natural cooling process. Partial crystallization leads to uneven composition of the sampled block, which affects the composition detection and analysis results. [0004] The Chines...
