Spectrum sampling mould of novel iron casting product

Abstract

The invention discloses a spectrum sampling mould of a novel iron casting product, which comprises an upper die and a lower die which are matched to use; the upper die comprises a first upper half die and a second upper half die which are matched to use; the first upper half die is connected with a first handle, and the second upper half die is connected with a second handle; the center where the first upper half die and the second upper half die are connected mutually is provided with an upper hole groove and a bottom groove which are connected to each other; bottom parts of the first upper half die and the second upper half die are provided with exhaust channels connected to the bottom die; one end of each of the first upper half die and the second upper half die is provided with a bolt hole and a bolt pin which are connected to each other. In the mould, the upper die and the lower die are cooperated to use; after filling molten iron, workers can easily open the upper die and take out samples; pure copper of the lower die can make the sample whitening more completely; the tested face of the sample is very good in quality, and the detection bias is greatly reduced.

Description

technical field [0001] The invention relates to a novel spectral sampling mold for cast iron products, which belongs to the field of casting. Background technique [0002] In the production process of casting, especially the production of iron castings, the percentage of chemical composition must be detected before the molten iron is poured, so as to guide the iron and steel smelting process and the final mechanical properties of the product. At present, most enterprises in the industry use direct-reading spectrometers to detect the composition before the furnace. This method has fast detection speed, many analysis elements, and high analysis accuracy, which can effectively control the chemical composition of products. The analysis of cast iron samples by direct-reading spectrometer requires that the analysis surface must be completely whitened, and rapid cooling is a necessary condition for realizing the full whitening of molten iron samples. The currently used cast iron...

AI Technical Summary

Problems solved by technology

This mold has the following disadvantages: 1. The weight of the upper mold plate is relatively large, it is troublesome to assemble and unload, and requires a large working intensity

2. The extremely cold block in the groove of the lower mold has poor heat conduction effect, and the complete whitening effect is poor

3. With the increase of the pouring times, the molten iron continuously heats and erodes the extremely cold block, resulting in defects such as pits and cracks on the surface of the extremely cold block, which seriously affects the whitening effect

Due to the use of grooves, the extremely cold block is placed in the groove and lower than the plane of the bottom plate after chip processing, so that the sample cannot be poured, and there is no reusability, resulting in a large cost waste
