からサンプルを取りだしていた。(Prior art) Oxidizing gases such as air, steam, CO 2 and O 2 are injected into hot metal to oxidize and remove impurities in the pig iron, and the heat generated by the oxidation of the impurities keeps the contents in the furnace constant. In the converter method, which obtains molten steel while keeping it in a molten state, during the blowing process, various characteristics such as the molten steel temperature or molten steel temperature, oxygen content, carbon content, etc. are measured, and molten steel component analysis values are measured using collected samples. Some operating methods are used to estimate the end point component value based on this value, but in this operating method, a sublance is inserted into the opening of the converter, and the molten steel temperature (or molten steel temperature and oxygen amount) is estimated. Various measurement factors such as the carbon content in the steel were measured, and samples for analysis of components (P, Mn, etc.) in the steel were also collected. When collecting samples using this sublance, a probe is attached to the tip of the sublance, which has a molten steel inlet opening on the side, and is configured so that the molten steel enters the mold provided below (on the tip side) and solidifies. The probe was immersed in molten steel of a converter and then recovered, and a sample was taken out from within the probe.

て高精度の開口部とする必要がある。(Problem to be solved by the invention) As mentioned above, according to the conventional probe P, in order to take out the collected sample, the probe P must be broken at the installation position of the sample mold 8 for analyzing the components in steel. However, this probe P
The openings tend to be the molten steel inlets 2 and 3 where stress is easily applied.For this reason, as in the probe P mentioned above, a separate sample for estimating carbon in steel is installed at the rear end of the sample mold 8 for component analysis in steel. Due to the structure in which the mold 6 is installed, if the opening becomes the second part of the molten steel inlet at the rear, the sample mold for analyzing the components in steel installed at the tip (below the probe P) 8, the sample collected within the probe P is folded while being trapped there, and therefore, it takes a long time to extract the sample from the broken probe P piece, which reduces the efficiency of the measurement work. It was coming. Further, when the molten steel sample inlets 2 and 3, which are easily subjected to stress, are bored on the side surface of the paper tube 1 of the probe P, the openings must be made with extremely high precision.

こと等の問題点を抱えている。 For this reason, advanced technology and equipment had to be used for the processing, making the processing work time-consuming.In short, with the conventional probe P mentioned above, it takes a long time to take out the sample.
Since it is necessary to install an opening for the inflow of molten steel on the side surface of the probe P, there are problems such as that the opening must be made with high precision.

可能となる。(Function) According to the sublance probe of the present invention, a sample mold for estimating the carbon content in steel is disposed in communication with the molten steel inlet, which is easily stressed, and the sample mold for estimating the carbon content in steel is attached to the tip of the mold. Since the mold is sealed with molding sand, which becomes brittle when subjected to heat load and mechanical shock, even if the opening becomes the molten steel inlet, the sample mold for steel component analysis can be easily removed. Therefore, the sample in the sample mold for analyzing the steel components can be easily taken out.
従つて、サンプルの取り出しが短時間で簡便に
でき、測定作業の能率も向上する。 Therefore, the sample can be taken out easily and in a short time, and the efficiency of measurement work is also improved.

Therefore, in the case of an operation method in which the end-point component values are estimated based on the molten steel analysis component values during converter blowing, conventional probes may not be able to predict the components in time for the end of the blowing, or the sample collection may be difficult. It was necessary to move the timing forward to meet the end of the blowing process, but in this case the estimation error would have been large, but with the probe of the present invention, this problem has been eliminated.
