Abstract
The invention provides a method for preparing magnetic stainless steel scrap core composite steel, comprising the following steps: S1, preprocessing stainless steel tubes; S2, preprocessing recycled waste stainless steel scrap; S3, spraying magnetic powder on the surface of stainless steel scrap; S4, Prepare the prepared raw material into a qualified billet to be rolled; S5, heat the billet, and then conduct rolling under the assistance of pulse current; S6, post-process the rolled composite plate, and finally prepare qualified magnetic stainless steel shavings Core composite steel. The invention uniformly sprays the magnetic particle material inside the stainless steel shavings, and applies a pulse current during the rolling process, and utilizes the multi-energy field joint excitation to effectively realize the preparation of the composite plate under small reduction and low temperature, and obtains a plate with good shape and high temperature. Corrosion-resistant, high-strength, good magnetic stainless steel shavings core composite steel.
Description
technical field [0001] The invention relates to a method for preparing steel, in particular to a method for preparing magnetic stainless steel scrap core composite steel. Background technique [0002] Metal shavings are by-products that cannot be ignored in the machining process, and have a significant impact on the production of an enterprise. As one of the most important metal filings, a large amount of scrap iron filings are produced every year. These scraps occupy a lot of space and are difficult to transport and store. Moreover, the surface of the scrap iron contains a lot of oil, which pollutes the environment and poses a great safety hazard. Hidden danger. The traditional recycling method is to clean off the oil stain on the surface of iron filings first, and then use them in furnace melting, briquetting, powder metallurgy, or production of chemical raw materials and chemical reagents. A common recycling method is to use machined carbon steel shavings and stainless ...
