Description

Treatment method of incineration and recycling of metal materials

The present invention relates to a processing method for incineration and recycling of metal materials; in particular, it refers to a method for further cracking or shrinking recycled objects in metal waste recycling operations, so as to reduce the transportation volume and shorten the follow-up operation time, and improve the quality and quality of recycled products. Reuse of value and other functions of technology.

Recycling metal (or stainless steel) scraps from waste incineration plants, and using the high-temperature molten metal (or stainless steel) reclaimed materials of steel mills to form metal liquids to make metal (or stainless steel) recycled products, achieving recycling, environmental protection, and economy The topic of benefit, the department has learned knowledge and skills. For example, Taiwan No. 82107709 "Methods and devices for continuous preheating of charge materials", the application of steelmaking raw materials mixed with waste incineration fly ash and other substances, and No. 90111315 "Recycling of waste incineration fly ash with electric arc furnaces through reduction and oxidation procedures" Typical examples are provided in the patent case of the "Steelmaking Method Used".

Traditional processing operations related to metal materials or waste recycling. Basically, metal recyclates recovered from combustion residues from waste incineration sites have been burned at extremely high temperatures, so many impurities, chemical residues, dirty substances or other attachments will be embedded or attached to the surface or between the material interlayers. , These attachments not only cause the burden of transportation, but also cause the difficulty of remelting the material during the regeneration operation, which greatly increases the operating cost and reduces the value of reuse; therefore, the attachments must be removed before recycling. To separate these attachments, the traditional processing operations include shearing operations, cutting (or crushing, rolling) the stainless steel recyclate into multiple smaller-volume primary bodies. In addition, the primary body is placed in an acidic agent, so that the acidic agent etches the primary body, and part of the lift-off attachments are dissociated and the cleaning operation is performed, so that the primary body forms a flattened body with a smaller volume. In practice, the completed experience is delivered to the steel plant, and is placed in the furnace at the same time as the new metal raw materials in an appropriate proportion, melted into a metal liquid at high temperature, and then made into metal recycling products.

The above-mentioned issues related to the implementation and operational application of this kind of metal waste recycling and treatment operations are that in order to dissociate the attachments from the metal recyclate (or the primary body) as much as possible, the acidic agent must be used to etch the primary body for a long time. Obviously Increase the time and cost of processing operations.

As those who are familiar with this technique know, acidic agents can only dissociate the attachments on the surface; therefore, there are still many attachments on the surface of the finished body. When the finished body is delivered to the steel plant, it is passed through the furnace. In the process of melting into liquid metal at high temperature, more ash and attachments will seriously hinder the melting operation of the recovered body, and after melting, these attachments will continue to be suspended on the molten metal or melted into the molten metal Situation. In order to improve or reduce the metal liquid impurities and avoid affecting the quality of recycled metal products, multiple slag removal operations must be carried out in the overall operation; not only the operation is troublesome and time-consuming, but also the time and cost of the processing operations are increased. Not what we expected.

In particular, the metal recycling material or the structural type in order to remove the attachments on the outer surface is a complete body structure in a loose (or larger surface area) state; therefore, the volume of transportation is greatly increased, making the The cost of transporting finished products to steel mills has increased significantly, thus significantly reducing the market value of recycled metal for reuse.

Typically, these reference materials show design skills related to metal (or stainless steel) waste or material recycling operations or treatment methods. If the metal material recycling method is redesigned to make its operation or process different from those of the accustomed, and considering the provision of further impurity or attachment dissociation technology special processing means, so that it can be combined with the recycling method, which will change the entire metal The operation mode of material recycling processing is different from the old method; in essence, it will significantly improve the processing time of the known techniques and the quality of metal recycled products.
