Method for manufacturing a metal scrap compression material

Abstract

The present invention relates to a method for manufacturing a metal scrap compression material. According to the method for manufacturing the metal scrap compression material, a through-hole is not punched after compressing the metal scrap compression material, but rather a through-hole is formed during the process of manufacturing the metal scrap compression material. Thus, even though the through-hole is formed in the metal scrap compression material which is compressed and formed so as to be highly dense, friction and stress applied to a core may be minimized to minimize the damage of the core and a failure occurrence rate.

Description

Technical field [0001] The invention belongs to the field of scrap metal briquetting manufacturing, and relates to a method for manufacturing scrap metal briquettes which compresses and processes collected scrap metal in various shapes so that the shape conforms to size specifications and can be directly put into a furnace for use. Background technique [0002] As we all know, through the waste generated in various production activities, the used (eliminated) waste molds in production activities, the steel bars generated from the dismantling of old buildings, and the scrapped automobiles, waste gas cans and metal cans generated in the consumption process. Metals are classified, collected, and re-smelted to manufacture various steels, which can save the resources and energy used in the steel-making process, and ultimately achieve the purpose of protecting the environment. For this reason, scrap metals of various shapes and materials need to be firstly classified, and then sor...

Problems solved by technology

On the contrary (the method of citing the invention) there are also many problems. This type of scrap metal briquette is to compress a large amount of scrap metal and increase its density, and their heat capacity is very high, which will consume a lot of energy. Long-term high-temperature smelting, high energy consumption in the smelting process has become one of the main reasons for increasing the manufacturing cost of steel products, and the increase in carbon dioxide emissions following high energy consumption has also become the main reason for environmental degradation

At the same time, although the previous scrap metal briquettes were made by briquetting the classified non-ferrous metal scrap and scrap iron separately, some unconscious processors added relatively heavy cement, etc. to the scrap metal. Manufacture of bad metal compacts, resulting in the pollution of the melting furnace for melting such bad waste metal compacts. It takes huge costs to eliminate the resulting pollution, and problems that affect production plans also occur from time to time. Difficulties encountered in the reuse of metal briquettes, which is also the current actual situation
