Problems solved by technology
In the initial stage, the physical method was used to test the metal iron content to indirectly reflect the metal recovery rate, but the separation of slag and iron was not complete during the metal iron test, and the sample preparation process was time-consuming and laborious. The sample preparation time for a single sample was about 40 minutes, and the metal iron test method It cannot truly reflect the yield of hot-briquetted iron in the converter smelting process
The test results have little guiding significance for production

Embodiment Construction
[0019] The device for detecting the water yield of iron-containing materials in the present invention is composed of a water cooler 1 , an intermediate frequency furnace 2 , an induction coil 3 , a graphite crucible 4 , and a cooling water pipe 6 .
[0020] As shown in the figure, the water cooler 1 is respectively connected to the water outlet and the water inlet of the intermediate frequency furnace 2 through the water inlet and water outlet of the cooling water pipe 6 to cool the intermediate frequency furnace 2 and the induction coil 3 . The cooling water supply mode is one valve and three channels, and the inner diameter of the cooling water pipe 6 is not less than 10 mm to ensure the cooling effect.
[0021] As shown in the figure, the induction coil 3 is fixed on the intermediate frequency furnace with splints and nuts, the induction coil 3 surrounds the graphite crucible 4, and the sample 9 is placed in the graphite crucible 4. The intermediate frequency furnace 2 feed...

The invention discloses a device and a method for detecting the liquid discharging rate of an iron-containing material, belongs to the technical field of metallurgical raw material inspection equipment and metallurgical raw material inspection methods, and is used for quickly detecting the liquid discharging rate of the iron-containing material. The invention adopts a technical scheme as follows:a water cooler is in cooling connection with an intermediate frequency furnace through a cooling water pipe, the intermediate frequency furnace is connected with an induction coil, the induction coilsurrounds a graphite crucible, and a test sample is placed in the graphite crucible. By virtue of an electromagnetic induction principle, a high-frequency current is applied to the induction coil to generate a strong alternating magnetic field which penetrates through the graphite crucible to melt metal iron in the iron-containing material so as to achieve separation of slag and iron; through calculation of the proportion of the metal iron in the test sample, the liquid discharging rate of the iron-containing material can be obtained, so that an inspection work becomes simple, the inspection cycle can be greatly shortened, the time and the labor are saved, and an inspection result can guide production; therefore, the device and the method are worth of popularization in the industry.
Description
technical field [0001] The invention relates to a detection device and method for the water yield of iron-containing materials, and belongs to the technical field of metallurgical raw material inspection equipment and methods. Background technique [0002] In the steel production process, scrap steel is an important production raw material, including purchased hot-briquetted iron. In the regulations on the quality acceptance of steel scrap purchased by enterprises, it is clearly stipulated that the water yield rate is an acceptance clause, but this inspection item has not met the inspection requirements. In the initial stage, the physical method was used to test the metal iron content to indirectly reflect the metal recovery rate, but the separation of slag and iron was not complete during the metal iron test, and the sample preparation process was time-consuming and laborious. The sample preparation time for a single sample was about 40 minutes, and the metal iron test meth...
