Abstract

The invention discloses a rapid detection method for the components of a lead alloy, and relates to the technical field of alloy production. The detection method specifically comprises the following steps that S1, a proper amount of lead alloy melt is taken and sequentially added into N molds, and water bath cooling is conducted from the outer sides of the molds for 1-1.5 min after pouring is completed; S2, the lead alloy blocks are taken out of the molds, and a rapid cooling agent is sprayed to the outer sides of the lead alloy blocks for 20-30 s; and S3, one lead alloy block is selected and clamped to a plane grinding machine through a clamp, one plane is ground firstly, and during grinding, the flatness of the ground plane is detected through a flatness detector. According to the method, the components of the lead alloy can be rapidly and efficiently detected in the production process, the detection accuracy is high, meanwhile, unnecessary detection can be effectively avoided, and the reliability of detection data is improved.

Description

technical field [0001] The invention belongs to the technical field of alloy production, in particular to a rapid detection method for lead alloy components. Background technique [0002] Lead alloy is mainly to add various other elements to lead in industrial production to improve the performance of lead. The finished product can be used to meet various needs in industry and life. In the production process of lead alloy In the process, the staff need to analyze the composition of the lead alloy finished product in order to ensure that the overall composition of the lead alloy can meet the qualified standards. Chemical agents are added to the powder for chemical analysis in order to obtain the content of various components. However, this analysis method of lead alloy components has the following deficiencies in actual use: [0003] 1. The overall operation of the method for analyzing the composition of lead alloys by means of chemical analysis is complex and cannot be appli...
