Embodiment Construction

[0025] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. figure 1 is a schematic cross-sectional view of the dual-sampling compound probe of the present invention. figure 2 a is a perspective view of the present invention assembled from a shell block and a ceramic head. figure 2 b is above figure 2 The cross-sectional view of a.

[0026] like figure 1 As shown, the compound probe 10 of the present invention is equipped with a shell block 14 having a sampler 12 for sample collection and a sensor 13 at one end of the long-axis multiple protection tube 11 . The sensor 13 is electrically connected to the connector through the sensor hole 17, and the connector 15 is connected to the host computer to exchange required signals. The temperature measurement, oxygen determination and other measurement information related to the molten metal collected by the sensor 13 are transmitted to the host computer.

Abstract

The present invention relates to a multifunctional combination probe, which is mounted on a holder of a temperature determination lance during a refining step in a steel mill and is then immersed in molten metal, thereby performing sensing functions such as temperature determination and oxygen determination or the like for the molten metal and sample extracting functions. The present invention, a combination probe for a dual sampler, comprises: a shell block that has sampling cases for sample extraction and a sensor, and is mounted at the end of one side of a long axial multi-protection pipe; and a connector that is electrically connected with said sensor, wherein said shell block has sensor holes which are disposed to allow the two sampling cases and the sensor to be inserted thereinto. According to the present invention, the combination probe obtains information on temperature determination and oxygen determination for the molten metal by a one-time measurement with the probe and extracts two samples at a time, thereby protecting against analytical problems which may occur, and contributing to an increase in refining efficiency and cost reduction, and can further be applied to various grades of steel.

Description

technical field [0001] The invention relates to a multifunctional composite probe, which is installed on the bracket of a temperature measuring gun in the refining process of a steel plant and then immersed in the molten liquid, so as to exert sensing functions such as temperature measurement and oxygen determination for molten metal And sample collection function. Background technique [0002] In general, in the refining process of a steel plant, the sample collection method for measuring the temperature and analyzing the composition of molten metal can be performed separately by using a dipping sampler after temperature measurement with a consumable thermocouple. However, in most cases, the following method is used: the composite probe is immersed once in the molten metal, thereby performing temperature measurement and sample collection operations at the same time. [0003] like Figure 6 As shown, in a common composite probe, the temperature sensor 1 and the sampler 2 ar...
