A kind of continuous casting two cold section steel billet infrared temperature measurement apparatusTechnical field
The utility model relates to smelting to be measured, particularly a kind of continuous casting two cold section steel billet infrared temperature measurement apparatus.
Background technology
Now, metallurgy industry extensively adopts continuous casting process, and its gordian technique keeps the highest pulling rate not rupturing, under the prerequisite of not bleed-out.The molten steel of tundish is shaping by crystallizer, and forms shell at outside surface, more progressively internally cools from shell through mist cold house, according to the shape of crystallizer mould, and round base, square billet or slab required for finally being formed.The temperature of all processes controls to be extremely important, and cooling is not enough, and temperature is too high, easily fracture and bleed-out accident occurs; It is excessive to cool, and temperature is excessively cold, then cause the reduction of pulling rate.Steel billet slow running, therefore the billet temperature measuring under steel billet motion state is very important, because on-the-spot fog is large, telemeasurement is infeasible, in-plant non-contact temperature measuring, again because conticaster breaks down sometimes, the time of workman's upkeep operation is very short, and in-plant temperature measuring equipment must be light and handy and can quick-detachment and installation.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous casting two cold section steel billet infrared temperature measurement apparatus technical scheme, and this device adopts infrared thermometer to be arranged on one in the structure of fast assembling-disassembling, can realize secondary cooling zone steel billet infrared measurement of temperature.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of continuous casting two cold section steel billet infrared temperature measurement apparatus, comprise a fast assembling-disassembling support, support is provided with infrared temperature probe, described fast assembling-disassembling support has one for inserting the inverted U groove of roll support body, a sidewall of inverted U-channel is provided with support clamping screw, an infrared temperature probe installing plate is connected with a sidewall of described U-lag perpendicular to inverted U-channel, described infrared temperature probe comprises sighting tube and infrared sensor, infrared sensor is arranged in sighting tube, the signal wire sheath that infrared sensor signal wire purges with band air is connected to temperature signal transmitter, described sighting tube is fixing on a mounting board.
Scheme is further: described signal wire sheath is metal enclosed sheath, airtight sheath is provided with cooling-air input interface, a cooling-air source is connected with signal wire sheath cooling-air input interface by pipeline, described infrared temperature probe sighting tube endoporus is communicated with airtight sheath, described infrared sensor is arranged in a hole of sighting tube front end-plate, described sighting tube front end-plate is also provided with venthole, and venthole is for purging clean tested billet surface.
Scheme is further: described installing plate is connected with sighting tube by bearing pin, be vertically fixed on installing plate centered by a corresponding bearing pin position of adjustable plate, on adjustable plate, corresponding bearing pin upper-lower position is respectively arranged with adjustment bolt, adjustment bolt withstands on sighting tube sidewall, rotates the setting angle that adjustment bolt can adjust sighting tube and installing plate.
Scheme is further: described sighting tube side-wall shaft is respectively arranged with long rabbet to both sides, and bearing pin snaps in long rabbet from sighting tube both sides, can be adjusted the position of probe front end distance steel billet by long rabbet up and down.
The technical program compared with prior art has following beneficial effect: structure is simple, the inverted U-shaped suspension member of support can carry out dismounting rapidly on roll erecting frame, and simultaneously adjustable plate and sighting tube side-wall shaft arrange the best measurement position that can regulate probe fast to both sides long rabbet; Be particularly suitable for the demand of continuous casting two cold section slab temperature measurement.
Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.

Embodiment
A kind of continuous casting two cold section steel billet infrared temperature measurement apparatus, as shown in Figure 1, described device is installed on continuous casting two cold section bloom production line 1, production line has billet roll 1-1; Described device comprises a fast assembling-disassembling support 2, support is provided with infrared temperature probe 3.
Described fast assembling-disassembling support has one for inserting the inverted U groove 2-1 suspension member of roll support body 1-2, a sidewall 2-1-1 of inverted U-channel is provided with support clamping screw 4, clamping screw can arrange multiple as required, an infrared temperature probe installing plate 5 is connected with a sidewall of described U-lag perpendicular to U-lag, described infrared temperature probe comprises sighting tube 3-1 and infrared sensor, and sighting tube is made up of high-quality 316 stainless steel.Infrared sensor is arranged in sighting tube, infrared sensor signal wire is drawn from sighting tube rear end by a fiber optic cables joint, the sheath 6 that signal wire purges with signal tape air is connected to temperature signal transmitter 7, transmitter has emissivity and peak value keeps and time constant regulatory function, electric signal is converted to the linear convergent rate of 4-20mA, display measurement temperature.Described sighting tube fixed installation on a mounting board; Said structure utilizes on-the-spot roll support body to achieve Fast Installation in dismounting, has adapted to the time of workman's upkeep operation very short work requirements.
In the operation of reality, owing to needing the angle of quick adjustment probe and steel billet, in the hope of the thermometric effect of the best, therefore, described installing plate is connected with sighting tube by bearing pin 8, and an adjustable plate 9 is vertically fixed on installing plate centered by corresponding bearing pin position, on adjustable plate, corresponding bearing pin upper-lower position is respectively arranged with adjustment bolt 10, adjustment bolt withstands on sighting tube sidewall, rotates the setting angle that adjustment bolt can adjust sighting tube and installing plate
In embodiment: described sighting tube side-wall shaft is respectively arranged with long rabbet 3-2 to both sides, bearing pin snaps in long rabbet from sighting tube both sides, can be adjusted the distance and position of probe front end distance steel billet up and down by long rabbet, it is a blind slot mouth that described notch and sighting tube endoporus do not communicate.
The adjust structure of above-mentioned setting can realize adjusting the thermometric at the upper surface of steel billet 11, side surface or rib place fast.
In embodiment: in order to ensure the works fine condition of signal wire, described signal wire sheath is metal enclosed sheath, described signal wire sheath is provided with cooling-air input interface 6-1, input interface is the gas-tpe fitting of fast demountable, and a cooling-air source 12 is connected with signal wire sheath cooling-air input interface by pipeline 13.In order to secondary cooling zone billet surface temperature can be measured accurately, described infrared temperature probe sighting tube endoporus is communicated with airtight sheath simultaneously, as shown in Figure 2, described infrared sensor is arranged in a hole 3-4 of sighting tube upper head plate 3-3, described sighting tube front end-plate is also provided with venthole 3-5, and venthole is for purging clean tested billet surface.
