Problems solved by technology
[0002] Stainless steel slag contains rare heavy metals such as nickel and chromium. If it is not handled properly, it will cause serious environmental pollution. At present, it is generally treated by a simple treatment method of open hot pouring. , the remaining tailings are transferred to the steel slag yard for storage. This conventional treatment method has a low metal recovery rate and has a bad impact on the production environment, which seriously restricts the efficient and intensive production of stainless steel manufacturers.

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand more clearly.
[0027] The processing method of the present invention adopts the wet processing method, avoids the generation of dry ash, and has reached the purpose of environmental protection processing casting slag, and described method comprises the following steps:
[0028] The slag tank filled with casting slag is hoisted to the supporting base inside the four retaining walls, and the dust removal cover is moved to cover the four retaining walls so that the slag tank is in a closed environment;
[0029] Turn on the electric water supply valve and adjust the spray volume, and the spray nozzle in the dust removal hood will spray water for the first time to cool the slag tank containing the casting residue;
[0030] Pour the casting slag in the slag tank cooled by the first water spray into the three retaining ...

The invention discloses a stainless steel casting slag treatment method and device. Due to the fact that a wet-process treatment mode is adopted in the treatment method, generation of dry ash is avoided, and the purpose of treating casting slag in an environment-friendly mode is achieved. The treatment device comprises slag pots loading the casting slag, a slag pot car transporting the slag pots, rails on which the slag pot car walks, a crane for lifting the slag pots, a cooling unit, a dust exhaust hood, a hot splashing field unit, a loading machine, a magnetic disk for attracting steel blocks and a dust removal unit. According to the treatment method, the stainless steel casting slag is treated by adopting the wet-process treatment mode and the treatment device, water spraying cooling is always conducted in an almost closed environment, therefore, generation of the dry ash is avoided, and a contribution is made for protecting the environment.
Description
technical field [0001] The invention belongs to the field of utilization of metallurgical solid waste resources, in particular to a method and device for treating stainless steel casting residue. Background technique [0002] Stainless steel slag contains rare heavy metals such as nickel and chromium. If it is not handled properly, it will cause serious environmental pollution. At present, it is generally treated by a simple treatment method of open hot pouring. , and the remaining tailings are transferred to the steel slag yard for storage. This conventional treatment method has a low metal recovery rate, which has a bad impact on the production environment and seriously restricts the efficient and intensive production of stainless steel manufacturers. Contents of the invention [0003] In order to solve the above-mentioned practical problems, the present invention provides a method and device for treating stainless steel casting slag, so as to realize efficient and envir...
