Tool for quickly producing spectral white cast sample

Abstract

The invention discloses a tool for quickly producing a spectral white cast sample. The tool comprises a base, two compound dies and a locating pin, wherein the two compound dies are movably connectedthrough the locating pin which is vertically arranged; the two compound dies are horizontally supported on the horizontal supporting surface of the base; through grooves are respectively formed in twoopposite sides of a compound die position of the two compound dies; first inverted conical half grooves are formed in the upper parts of the through grooves, and second inverted conical half groovesare formed in the middle parts of the through grooves; an angle between a generatrix and a center line of the first inverted conical half grooves is greater than an angle between a generatrix and a center line of the second inverted conical half grooves; cylindrical half grooves are formed in the lower parts of the through grooves; when the two compound dies are in a clamping state, the two through grooves are spliced to form a circumferentially closed forming cavity of the spectral white cast sample. The tool disclosed by the invention is beneficial for fast pouring and die pulling, a samplecannot be easily oxidized during a pouring process, and the sample with higher white level can be formed.

Description

technical field [0001] The invention relates to the technical field of detection of chemical components of molten iron, in particular to a tool for rapidly preparing spectral white samples. Background technique [0002] A spectroscopic sample is a sample block used for spectroscopic detection of chemical composition. The detection part of the spectral sample must be as large as possible. In the process of spectral sample preparation, there are often shrinkage cavities, impurities and cracks on the surface, and the degree of whitening of the detection surface is not high, which affects the detection accuracy of chemical components. At present, the sample preparation tooling for preparing spectral white samples has a slow sample preparation speed, and it is impossible to obtain samples with flat, clean surfaces and a high degree of whitening. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present inven...
