The carbon detecting device comprises a carbon detecting probe, a carbon detecting gun connected with the carbon detecting probe, an indicator connected with the carbon detecting gun, a crystallization thermometer connected to the indicator, and a signal processor connected with the indicator, wherein, the carbon detecting gun, the indicator and the signal processor are all connected with each other by adopting conducting wires. The carbon detecting device has the characteristics of being able to solve the problem of detecting the content of molten steel carbon in the blowing process of the converter with the load of 90t or below, so that the hit rate of end-point carbon can be greatly improved, the quality of molten steel is obviously improved, and the alloy yielding rate is also increased.
Description
Technical field
The utility model relates to surveying instrument, specifically belongs to the carbon testing device that is used for 90 tons and following converter.
Background technology
At present, the middle-size and small-size converter below the domestic 90t can not be installed sublance because the space is limited, can only measure liquid steel temperature in the converting process, and the carbon content in the molten steel can't detect, and terminal point catch carbon, temperature adjustment are leaned on manual work by rule of thumb fully.Cause often occurring the inaccurate phenomenon of end point carbon control, have a strong impact on steel quality, promptly the end point carbon height causes the molten steel carbon component offscale easily; The oxygen level height causes that oxide inclusion increases in the molten steel in the low molten steel of end point carbon, and the yield of alloy reduces simultaneously.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, and the detection of bessemerizing carbon content of molten steel in the process below a kind of 90t of solution problem is provided, and for the terminal point catch carbon provides reference frame, improves the hit rate of end point carbon.
Realize the technical measures of above-mentioned purpose:
Be used for the carbon testing device of 90 tons and following converter, it is characterized in that: the signal processor that it comprises the carbon determination probe, pops one's head in the carbon determination rifle that is connected, the telltale that is connected with the carbon determination rifle, the Tc table that is connected in telltale, is connected with telltale with carbon determination; All adopt lead to connect between carbon determination rifle, indicator signal and the signal processor.
It is characterized in that: described telltale is made up of the retaining plate of green three PL of reddish yellow and fixing three PL.
It is characterized in that: signal processor also is connected with computingmachine steel-making mathematical model through lead.
The characteristics of the utility model are to solve the detection problem of bessemerizing carbon content of molten steel in the process below the 90t, and the end point carbon hit rate is significantly improved, and steel quality has clear improvement, and yield of alloy also is improved.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: 1-carbon determination probe, 2-carbon determination rifle, 3-lead, 4-telltale, 5-PL, 6-retaining plate, 7-signal processor, 8-Tc table, 9-computingmachine steel-making mathematical model.
Embodiment
Do below in conjunction with accompanying drawing and to further describe:
The carbon testing device that is used for 90 tons and following converter: carbon determination probe 1, carbon determination rifle 2 and carbon determination 1 suit of popping one's head in is connected, and lead 3 passes carbon determination rifle 2 and carbon determination and pops one's head in and 1 be connected; To be connected with signal processor 7 through lead 3 by red, yellow, green three PL 5 and with telltale 4 that retaining plate 6 is formed; Tc table 8 is installed on telltale 4, and Tc table 8 also is connected with lead 3; Signal processor 7 also is connected with computingmachine steel-making mathematical model 9 through lead 3.
Operating principle
On carbon determination rifle 2, plug carbon determination probe 1 before measuring, signal is connected, and the green indicating lamp 5 on the telltale 4 is bright; In when falling the stove once, carbon determination probe 1 is inserted in the molten steel, treat PL 5 yellowings; Explain and measure to finish that then carbon determination probe 1 is mentioned and leave molten steel, PL 5 becomes redness; At this moment, Tc table 8 temperature displayed value is the molten steel Tc, shows and measures successfully; Through lead 3 Tc table 8 temperature displayed value is transferred to signal processor 7, then demonstrates the carbon content in the molten steel after handling through signal processor 7; Operator are transferred to computingmachine steel-making mathematical model 9 with these data through lead 3 again and carry out related work according to the carbon content situation.After will be take off with carbon determination probe 1, more renew carbon determination probe 1 and prepare for next stove measurement.
Claims (3)
