Abstract

The invention relates to a method for detecting the water yield of a steel hot briquetting block. Samples are taken from a car equipped with the steel hot briquetting block, and a steel hot briquetting block is taken from a car as a sample block and the quantity of the obtained sample block is measured. When the specified value is reached, it is compiled into a group of sample blocks, and the four points of each sample block are drilled for iron filings, and a group of iron filings are gathered into the crucible, and the iron filings are melted by a high-frequency induction furnace during the melting process. Constantly adjust the current to reduce the spatter of iron filings during the melting process. After heating until the slag and iron are separated, the induction furnace is closed. After the temperature reaches a certain level, the crucible is taken out for cooling. After cooling, the crucible is broken open, and the sample block is taken out and removed Surface impurities, calculate the water yield of the sample. The present invention avoids the phenomenon of large error due to material non-uniformity through group sample preparation, and increases the calculation accuracy of the water yield of the steel hot briquetting block.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a method for detecting the water yield of a hot briquetting block of steel. Background technique [0002] The hot-pressed block is produced by the direct reduction technology of fine ore. The iron ore is improved to 67.5-68% after beneficiation. The reducing gas is natural gas. The reformed natural gas is processed into H2 and CO. The ore and the reducing gas flow in the opposite direction. After four-stage reduction, sponge iron is obtained, and then hot-pressed molding is performed to obtain the final product----hot-briqueted iron. , which contains 92%-93% of total iron, 1-1.1% of carbon, 0.01% of harmful elements, and the content of powder is less than 2%. Hot briquetted iron has the common characteristics of ordinary sponge iron: high purity, low content of harmful impurities, which is conducive to the production of high-quality steel, uniform quality, high strength, lo...
