Embodiment 1

[0043] A kind of frock for making molten steel sampler of the present embodiment comprises metal cap 1, quartz tube 2, coated sand 3, sample box 4, backing plate 5, outer sheath pipe 6 and inner sheath pipe 7, also includes metal Casing tube 8; wherein: the outer diameter of the inner sheath tube 7 is the same as the inner diameter of the outer sheath tube 6, both of which are made of kraft paper, and the inner sheath tube 7 is set on the lower half of the outer sheath tube 6; the backing plate 5 is circular , is also made of paper, covering the upper end surface of the inner sheath tube 7; the sample box 4 is a flat structure in the shape of a "ping-pong racket", which is formed by buckling two symmetrical halves, and stands upside down vertically on the center of the backing plate 5 The place is made of iron; the quartz tube 2 is seamlessly inserted into the inside of the round handle of the sample box 4 "table tennis racket"; the metal sleeve 8 is made of iron in this embodi...

Embodiment 2

[0056] A kind of frock for making the molten steel sampler of the present embodiment has solved the problem of the embodiment 1 through the efforts of the inventor and a series of tests.

[0057] A kind of frock of making molten steel sampler of the present embodiment, its basic structure is the same as embodiment 1, and the improvement is: as figure 1 As shown, the positioning hole 51 of the sample box 4 is set at the center of the backing plate 5, and the positioning ring A81 of the metal cap 1 and the positioning ring B82 of the sample box 4 are respectively arranged in the metal sleeve 8 along the inner wall; the inner diameter of the positioning ring A81 and the metal The outer diameter of cap 1 is identical, and is fixedly connected together with the top of metal cap 1, and location ring A81 is mesh shape, and the inner diameter of location ring B82 is identical with the outer diameter of " table tennis racket " circular handle of sample box 4, also It is mesh-shaped, an...

Embodiment 3

[0069] A kind of tooling of making molten steel sampler of the present embodiment, its basic structure is the same as embodiment 2, and difference is: the material of metal cap 1 is iron; There are 2 reinforcing ribs 61, left and right symmetrically arranged; The vertical distance from the filling surface to the upper end surface of the outer sheath pipe 6 is 2 / 3 of the height of the entire coated sand 3; the metal casing 8 is made of iron; there is no aluminum wire in the "table tennis racket" circular handle of the sample box 4.

Abstract

The invention belongs to the technical field of tools for manufacturing molten steel samplers and discloses a tool for manufacturing a molten steel sampler and a method for manufacturing the molten steel sampler by adopting the tool. The tool comprises a metal cap, a quartz tube, precoated sand, a sample box, a base plate, an outer protective casing pipe, an inner protective casing pipe and a metal sleeve, wherein the outer diameter of the inner protective casing pipe is equal to the inner diameter of the outer protective casing pipe, and the lower half part of the outer protective casing pipe is sleeved with the inner protective casing pipe; the base plate covers the upper end surface of the inner protective casing pipe; the sample box adopts a flat structure and is formed by buckling two symmetrical half box bodies; the quartz tube is seamlessly inserted into a handle of the sample box; the inner diameter of the metal casing pipe is equal to that of the outer protective casing pipe, and the metal casing pipe is arranged on the upper end surface of the outer protective casing pipe; a gap between a cavity formed by the metal casing pipe, the outer protective casing pipe and the base plate and the sample box is filled with the procoated sand, and a filling surface is lower than the pipe orifice of the metal casing pipe; the open end of the metal cap is inserted into the precoated sand, and the sealed end of the quartz tube covers the top of the quartz tube. By means of the molten steel sampler manufactured by adopting the tool, sampling can be quickly performed, the sample box is easy to take out, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a tool for making a molten steel sampler, in particular to a tool for making a molten steel sampler and a method for making the molten steel sampler. Background technique [0002] Molten steel sampling is to quickly take samples out of liquid steel for rapid spectral analysis, so as to obtain the composition and homogeneity of the molten steel in the furnace, which is used to guide the smelting process. The basic premise of accurately collecting data such as molten steel temperature and composition is that the time from sampling to obtaining analysis results is as short as possible. If the sampling speed is slow, the analysis results of even the most sophisticated instruments are of no reference value. Therefore, the sampling speed is the key, and the development of a simple and fast sampler is the key to the success of the spectral analysis before the steelmaking furnace. In the traditional sampler, the sample box is complet...
