Abstract

Structure of the utility model is the utility model comprises a crucible body 1 with an inner cavity 2. A truncated cone 3 is positioned in the middle of the outer bottom of the crucible body 1, and a small round pit 4 is arranged in the middle of the truncated cone 3; the internal diameter and the external diameter of the upper end of the crucible body 1 are respectively 24mm and 19mm; the depth and the bottom diameter of the inner cavity 2 are respectively 19mm and 16mm, and the height of crucible body 1 is 24mm; the utility model provides the users with 24 types of products which can fill the market vacancy. The product has low thermal loss due to the structure. Because of the light weight and constant volume, the heat can be concentrated on standard samples while using, thereby raising the melting temperature and speeding up the melting rate of the standard samples efficiently.

Description

Metallurgical analysis low-carbon and low-sulphur crucible

Technical field

The utility model relates to a kind of crucible that is used for metallurgical analysis.

Background technology

Along with the development and the continuous advancement in technology of society, the metallurgical analysis of prior art, haves much room for improvement and innovates because specification is of less types and technical feature is limited can not satisfy actual needs with crucible.

Technology contents

The purpose of this utility model is, designs a kind of metallurgical analysis low-carbon and low-sulphur crucible, it to have that self heat waste is little, volume is little light with weight and relative volume greatly, can effectively improve characteristics such as standard specimen melt temperature, on product specification, filled up blank.

The technical solution of the utility model is, described metallurgical analysis has the crucible body of band inner chamber with the low-carbon and low-sulphur crucible, there is round platform at the outer bottom middle part of described crucible body, its design feature is, there is a small circular pit at described round platform middle part, the internal diameter and the external diameter of described crucible body upper port are respectively 24mm, 19mm, and the degree of depth of inner chamber and base diameter are respectively 19mm and 16mm, and the height of crucible body is 24mm.

Below make and further specifying.

Referring to Fig. 2, the utility model has the crucible body 1 of band inner chamber 2, there is round platform 3 at this crucible body 1 outer bottom middle part, its technical characterstic is, there is a small circular pit 4 at described round platform 3 middle parts, internal diameter of crucible body 1 upper port (being the upper port diameter of its inner chamber) and external diameter are respectively 24mm, 19mm, and the degree of depth of inner chamber 2 and base diameter are respectively 19mm and 16mm, and the height of crucible body 1 (not containing round platform 3 height) is 24mm.The utility model product can adopt the starting material of prior art and manufacture craft to produce in batches.The tolerance of above-mentioned size (being Fig. 2 institute dimensioning) remains on ± and 0.3mm is advisable.

As known from the above, the utility model is a kind of metallurgical analysis low-carbon and low-sulphur crucible, and its advantage has: because described structure, it is thick to have reduced the crucible body wall than traditional product; And provide " 24 type " (specification) crucible that is suitable for actual needs, filled up the market vacancy; Make thus that the crucible volume reduces, weight saving and the constancy of volume, its heat waste is corresponding to be reduced; In use, during the higher-order of oscillation heating heat is concentrated on the standard specimen, effectively improve melt temperature (effectively making the standard specimen fusion).

Description of drawings

Fig. 1 is the vertical view of the utility model product;

Fig. 2 is the positive sectional structure chart of the utility model product.

In the accompanying drawings, 1-crucible body, 2-inner chamber, 3-round platform, 4-small circular pit.

Embodiment

Referring to Fig. 1 and Fig. 2, actual size size of the present utility model is made with reference to dimensioning shown in Figure 2, and tolerance is at ± 0.3mm, and all the other making can be identical with the prior art content.

Claims

1, a kind of metallurgical analysis low-carbon and low-sulphur crucible, the crucible body 1 that band inner chamber 2 is arranged, there is round platform 3 at described crucible body 1 outer bottom middle part, it is characterized in that, there is a small circular pit 4 at described round platform 3 middle parts, the internal diameter and the external diameter of crucible body 1 upper port are respectively 24mm, 19mm, and the degree of depth of inner chamber 2 and base diameter are respectively 19mm and 16mm, and the height of crucible body 1 is 24mm.
