Processing technology of hard alloy material

Abstract

The invention discloses a processing technology of a hard alloy material. The processing technology comprises the following step that S1, a mixture is prepared, specifically, all required component raw materials and a small amount of additive are weighed, the raw materials comprise WC and TiC, the additive is a Co adhesive, the raw materials and the additive are loaded into a rolling ball mill, the mixture is refined and uniformly distributed in a hexane grinding medium by utilizing the impact and grinding effects of an alloy ball grinding body in the ball mill, then a certain amount of liquid paraffin is added, after discharging, spray drying is carried out through a spraying mechanism, vibration sieving is carried out through a vibration mechanism, and a wax mixture with certain components and granularity requirements is prepared. According to the processing technology, through the cooperative work between the spraying mechanisms, the materials inside a processing box are sprayed from the inside and the outside through a first mist outlet guide pipe on a mist outlet pipe and a second mist outlet guide pipe in a transmission pipe, so that all positions of the materials can be subjected to the spraying effect, and the materials can be sprayed more thoroughly.

Description

technical field [0001] The invention relates to the technical field of hard alloy processing, in particular to a processing technology for hard alloy materials. Background technique [0002] Cemented carbide is a kind of hard material composed of refractory metal hard compound and bonding metal. It is produced by powder metallurgy method and has high wear resistance and certain toughness. Due to its excellent performance, cemented carbide It is widely used in cutting processing, wear-resistant parts, mining, geological drilling, oil exploration, mechanical accessories and other fields. [0003] The processing of cemented carbide is divided into mixture preparation, pressing, and sintering. In the process of mixture preparation, it is necessary to carry out spray drying and vibration screening on the unloaded materials. On the one hand, the spray drying effect of the existing technology is not good. Well, generally, spray drying from one angle makes the other parts of the mi...
