Abstract
The invention discloses an apparatus and a method of preparing a micro coked sample for coke microstructure determination. The apparatus comprises a support member, a compacting member and a cylinder member; the support member has a door-shaped structure by a support pedestal, a support and a crossbeam which are in fixed connection; the middle part of the pedestal is provided with a circular base for disposing a cylinder; the compacting member consists of a compacting heavy block, a smashing heavy hammer, a separation sheet, a hammerhead and a striking pin; and the cylinder member consists of a cylinder wall, a base and a press cover, and the center of the press cover is provided with a volatile-matter diffusing hole. The apparatus and the method can help to prepare a micro coke sample with proper size, the micro coke sample is subjected to molding by putting in a rubber mold, and the obtained molded sample is subjected to polishing and then is directly put under a microscope for observation. The usage amount of a coal powder is less, the sample preparation time is short, damage to the coke texture in a crushing process of a conventional method is avoided, and the coke microstructure can be continuously determined under the microscope, and thus the coke microstructure determination process is convenient and accurate.
Description
technical field [0001] The invention relates to a microcoking sample preparation device and method for measuring coke microstructure, belonging to the research field of coke microstructure properties in coke chemistry. Background technique [0002] Coke plays the role of reduction, heat source and supporting skeleton in blast furnace ironmaking. With the development of blast furnaces to large volumes, the requirements for coke cold strength and hot performance are getting higher and higher. The microstructure of coke is one of the important factors affecting the cold strength and hot performance of coke. The traditional sample preparation method for the determination of coke microstructure is to prepare large pieces of coke, then crush, sieve coke powder particles of 0.2mm-1.0mm, and use resin to cure and shape them into a size of 2.5cm×2.5cm×2.0cm The samples were polished and observed under a microscope. A large amount of coal powder is required for each sample preparati...
