Embodiment Construction

[0010] When the present invention is concretely implemented, a kind of waste metal slag recycling process comprises the following steps:

[0011] Step 1. Put the waste metal slag into the pulverizer and crush it into 8mm granular shape, then fill it into the smelting furnace;

[0012] Step 2, adding industrial fuel into the smelting furnace to fully burn the granular waste metal slag in step 1, and the combustion environment standard is 300-500 ° C for 10-12 hours of continuous combustion;

[0013] Step 3: Pour the metal molecules burned in Step 2 out of the smelting furnace and cool naturally to form scrap metal blocks.

[0014] The industrial fuel used in said step 2 includes but not limited to industrial white oil, 3# crude white oil and other industrial fuels.

[0015] The working principle of the present invention: the production process is as follows: the purchased waste metal slag is burned for 10-12 hours by burning industrial fuel at low temperature to extract the me...

Abstract

The invention discloses a recycling technology of waste metal slag. The recycling technology comprises the following steps that firstly, the waste metal slag is put into a pulverizer to be pulverized into particles of 8 mm, and then the particles are put into a smelter; secondly, industrial fuel is added into the smelter, the granular waste metal slag in the first step is fully combusted, and continuous combustion is conducted for 10-12 h at the combustion environment standard of 300-500 DEG C; and thirdly, the metal molecules combusted in the second step are poured out of the smelter and naturally cooled, and waste metal blocks are formed. Compared with the prior art, the recycling technology has the advantages that the process steps are clear and reasonable, the technology indexes of the steps meet the industrial standard, the purchased waste metal slag is subjected to low-temperature combustion for 10-12 hours by combusting industrial fuel, metal molecules in the waste metal slag are extracted, then the waste metal slag is cooled into waste metal, the cost is low, the method is convenient, the applicability is good, and popularization is convenient.

Description

technical field [0001] The invention relates to metal recycling, in particular to a recycling process for waste metal slag. Background technique [0002] Metal recycling refers to the useful substances separated from scrap metals that are physically or mechanically processed into recycled products. It is an industrial chain from recycling, dismantling, and recycling. The metal recycling industry has formed a complete industrial chain and recycling ecosystem. This industrial chain starts from foreign scrap suppliers and passes through traders, importers, agents, ports, dismantling factories (designated enterprises or hardware factories), recycling companies, metal processing factories and other links to realize the effective use of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing metal recovery and reuse process has low actual recovery efficiency and poor molding effect of the finished product du...
