High-carbon ferro-chrome powder processing technology and production line for processing high-carbon ferro-chrome powder

Abstract

The invention relates to a high-carbon ferro-chrome powder processing technology and a production line for high-carbon ferro-chrome powder processing, and relates to the field of metal powder processing technology. The high-carbon ferro-chrome powder processing technology comprises the following steps: preliminary crushing treatment on metal raw materials: crushing the high-carbon ferro-chrome raw materials into particles through a crusher; crushing treatment of the metal raw materials: crushing the granular high-carbon ferrochrome raw materials into powder through a pulverizer; screening of the metal raw materials: screening the powdery high-carbon ferrochrome raw materials through a screening machine, and thus obtaining high-carbon ferrochrome powder of which the fineness meets the requirement; mixing of the metal raw materials: fulling mixing the high-carbon ferrochrome powder through a mixing machine, and thus obtaining finished high-carbon ferrochrome powder that is uniform in thickness, the high-carbon ferrochrome powder comprising 55%-65% of Cr, 1%-3% of Si, 7%-9% of C, 0.01%-0.04% of P, 0.01%-0.05% of S and the balance of Fe. The high-carbon ferrochrome powder has the effect of improving the using effect of the metal powder in a welding process.

Description

technical field [0001] The application relates to the field of metal powder processing technology, in particular to a high-carbon ferrochrome powder processing technology and a production line for high-carbon ferrochrome powder processing. Background technique [0002] Welding material refers to the general term for the materials consumed during welding, such as welding rod, welding wire, metal powder, flux, gas, etc. High carbon ferrochrome powder is one of the important materials required by the welding industry. [0003] The inventor believes that in the related art, the metal raw material is directly converted into a powder form by crushing and grinding. Since the metal raw material in the powder form has inconsistent thickness after crushing and grinding, it will affect the metal powder in the welding process. Effect. Contents of the invention [0004] In order to achieve the purpose of improving the use effect of metal powder in the welding process, the application ...
