The invention discloses a method and a device for detecting blast furnace slag crystals, and relates to the technical field of materials. The method for detecting the blast furnace slag crystals comprises the following steps: precipitating rutile crystals prepared from titanium-containing blast furnace slag, cooling the rutile crystals in a circulating water cooling tank for 5-10 h, and then drying the cooled rutile crystals at 40-50 DEG C to obtain a sample to be tested; and sequentially carrying out titanium dioxide content analysis, enrichment degree analysis and morphology analysis on thesample to be tested, wherein the enrichment degree analysis is performed by analyzing an X-ray diffraction pattern, and the morphology analysis is performed by a scanning electron microscope; and thewater cooling tank includes a cooling chamber, a water inlet pipeline and a water outlet pipeline located on the cooling chamber. The device for detecting blast furnace slag crystals comprises the circulating water cooling tan
