Abstract

The pellet preparation method according to the embodiment of the invention comprises the following steps: recovering dust generated in a ferronickel preparation process for later use; a process for preparing a binder using first slag, which is slag generated in a ferronickel preparation process, and a by-product generated in a process other than the ferronickel preparation process; and mixing the dust and a binder, and granulating to prepare pellets. Therefore, according to the preparation method of the pellets in the embodiment of the invention, the binder with the cost lower than that of the prior art can be prepared. In addition, when the binder according to the embodiment is used for preparing pellets serving as raw materials for preparing ferronickel, the pellets with the strength similar to that of pellets prepared by using existing binders or the strength of the pellets is improved can be prepared.

Description

technical field [0001] The invention relates to a method for preparing pellets and a binder, and pellets prepared by using the same. In more detail, the present invention relates to a method for preparing pellets and a binder which can reduce the cost for preparing pellets, and pellets prepared using the same. Background technique [0002] The molten steel used to make stainless steel is generally produced through a refining process in which a nickel and chromium-containing molten iron is prepared by melting solid ferronickel, ferrochromium, and scrap iron, and carbon is removed from the prepared molten iron. [0003] The process of preparing ferronickel includes: the process of drying nickel-containing ore (hereinafter referred to as nickel ore), the process of roasting and pre-reduction of the dried nickel ore, and charging the roasted and pre-reduced nickel ore into an electric furnace. The process of melting and reduction, the desulfurization process of removing sulfur ...
