Molten iron sample production by vibration smashing method

Abstract

The invention relates to a method for preparing iron water sample by adopting vibration pulverizing method, which adopts vibrating mill. The method comprises the following steps: 1) confirming the iron water sample stations respectively before desulphurization and after desulphurization, and determining the equipment parameters accordingly, where the vibration time is 5-40 seconds, the sieving particle size is 120-200 mu, and the tungsten steel or tungsten carbide millstone is used; 2) preparing sampling according to the determined equipment parameters; 3) screening the sample according to the particle size required in the infrared instrument analysis, and putting into sample box. By adopting vibration mill to grind sample, the method provided by the present invention greatly reduces worker labor intensity, and increases working efficiency.

Description

technical field [0001] The invention relates to a method for preparing molten iron samples, in particular to a method for preparing molten iron samples by vibrating pulverization. Background technique [0002] With the rapid development of steelmaking technology, the requirements for laboratory results are getting higher and higher. Infrared method has been used to measure carbon and sulfur in molten iron. In terms of sample preparation of molten iron, manual crushing of molten iron samples has been used for carbon and sulfur analysis. Although the precision of the current chemical instruments can fully meet the production needs, the manual sample preparation method is primitive, rough, and slow, which greatly affects the accuracy of the analysis, and it is difficult to meet the production requirements of short-process and fast steelmaking. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and proposes a time-saving and labor-sav...
