Abstract

The utility model relates to the field of refractory, in particular to an unburned refractory brick of a steel converter. The unburned refractory brick of the steel converter for measuring thickness and automatically alarming is characterized by comprising a refractory brick body and conducting metal wires, wherein the conducting metal wires are pre-embedded into the refractory brick body and are parallel to the inner surface of a steel converter casing; and detection end wires are led from the conducting metal wires at one side on the outer side of the steel converter casing. According to the unburned refractory brick, the real-time measurement of actual thickness of a key area for the steel converter can be realized; the unburned refractory brick can provide powerful support and supplement for a laser thickness gauge; particularly when slag is attached to a converter opening and no enough time is used for arranging the measurement, the unburned refractory brick can be used for quick detection; the unburned refractory brick has a simple structure and is convenient to judge and operate; the thickness measurement time of the steel converter can be greatly saved; potential safety hazards due to excessive melting loss of backup lining bricks can be avoided; and the unburned refractory brick provides an economic and suitable monitoring method for medium-sized and small steel plants incapable of purchasing laser thickness gauges.

Description

Thickness measuring is used the steel melting furnace non-burning refractory brick from reporting to the police

Technical field

The utility model relates to fire resisting material field, relates in particular to a kind of steel melting furnace non-burning refractory brick.

Background technology

At present, known refractory materials on stove in the use monitoring of thickness most of by the artificial visually examine, stove that some are crucial such as converter have adopted the thickness measurement with laser system to monitor the safe thickness of furnace lining or by methods such as casing temperature and refractory materials thermal conductivity calculated thickness.These methods all can not intuitively be measured and the reality demonstration in real time to the refractory materials actual (real) thickness.

Steelworks adopts the residual thick of thickness measurement with laser technology for detection converter working lining magnesia carbon brick at present, each general 15 minutes time, situation that frequent generation can't be measured according to plan in the rhythm of production anxiety of needing of measuring.In order to overcome the shortcoming of traditional converter magnesia carbon brick thickness detection mode, the converter magnesia carbon brick is had in use realize the ability of reflection actual thickness automatically, need a kind of custom-designed non-burning refractory brick.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of thickness measuring and uses the steel melting furnace non-burning refractory brick from reporting to the police, the inner pre-buried conductive wire line loop of this refractory brick body, the mode that melting loss or the destruction by the refractory brick body causes the galvanic circle to disconnect realizes the residual thick measurement of brick body.

The utility model is achieved in that a kind of thickness measuring is from warning steel melting furnace non-burning refractory brick, constitute by refractory brick body and conducting metal silk thread two portions, described conducting metal silk thread is embedded in the refractory brick body parallel with steel melting furnace furnace shell internal surface, and the conducting metal silk thread is drawn the detection end line in steel melting furnace furnace shell outer wall one side.

Total many of described conducting metal silk thread is set in parallel in the refractory brick body.

Described refractory brick body is magnesia carbon brick or aluminum-silicon carbide brick.

The utility model thickness measuring is from reporting to the police with the steel melting furnace non-burning refractory brick at the inner pre-buried conductive wire line loop of refractory brick body, melting loss or destruction by the refractory brick body cause the mode of galvanic circle disconnection to realize the residual thick measurement of brick body, realized real-time measurement to steel melting furnace critical area actual (real) thickness, can strong support is provided and replenish laser thickness gauge, especially when the fire door dry slag or when not having enough arrangements of time to measure, utilize the utility model can accomplish rapid detection; The utility model is simple in structure, decision operation is convenient, and can save the time of steel melting furnace thickness measurement greatly,, can stop the potential safety hazard that causes because of backup lining brick transition melting loss for the medium and small steel mill of unable purchase thickness measurement with laser instrument economic and practical monitoring method especially.

Description of drawings

Fig. 1 is that the utility model thickness measuring is from reporting to the police with steel melting furnace non-burning refractory brick structural representation;

Among the figure: 1 refractory brick body, 2 conducting metal silk threads, 3 detect end line.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

As shown in Figure 1, a kind of thickness measuring is used the steel melting furnace non-burning refractory brick from reporting to the police, constitute by refractory brick body 1 and conducting metal silk thread 2 two portions, described refractory brick body 1 is magnesia carbon brick or aluminum-silicon carbide brick, described conducting metal silk thread 2 is embedded in the refractory brick body 1 parallel with steel melting furnace furnace shell internal surface, and conducting metal silk thread 2 is drawn in steel melting furnace furnace shell outer wall one side and detected end line 3.

Described in the present embodiment conducting metal silk thread 2 has many, is set in parallel in the refractory brick body 1.Fusing can't the conducting electric current after refractory brick body 1 melting loss makes conducting metal silk thread 2 exposed, so in use whether conducting is judged by detecting conducting metal silk thread 2, if conducting explanation refractory brick body 1 does not also have melting loss or destruction at this thickness, if not conducting then illustrate that refractory brick body 1 has taken place by melting loss or destruction.Conducting metal silk thread 2 can be embedded in the appointed thickness position reaching the thickness warning function, and the many conducting metal silk threads 2 that are embedded in different thickness can also be realized the function of thickness measuring.

Choose the most serious zone of steel melting furnace melting loss in use, build the utility model thickness measuring by laying bricks or stones and use the steel melting furnace non-burning refractory brick from reporting to the police, when needing to measure backup lining brick thickness in the converter use, respectively the detection end line 3 of different thickness is measured, the pre-buried degree of depth of the conducting metal silk thread 2 of a darkest pre-buried conducting promptly can be considered the true residual thick of this zone of present furnace lining.
