Abstract
The utility model relates to a small-sized infrared temperature measurement device, which comprises an infrared temperature measuring instrument probe. The small-sized infrared temperature measurement device is characterized in that the infrared temperature measuring instrument probe is installed in a left-turned U-shaped water cooler (25), a water-cooled casing is formed by a clean gas purge device (22), the left-turned U-shaped water cooler (25) arranged inside the two sides and a cooled water guide plate (24); and a rear cover (27) and the water-cooled casing form a sealing body through a buckle (26). Cooled water enters the water cooler (25) through a cooled water inlet (1), and flows out through a cooled water outlet (2) after passing the inner water cooling path. For the reason that the cooled water passes the particular loop, the cooling efficiency is high, the use quantity of the cooled water is small, so that the temperature measuring instrument can achieve accurate temperature measurement in a steel hot rolling production line and/or float glass production line under severe high temperature condition, meanwhile, the purposes of water saving and energy saving are achieved.
Description
Technical field
The utility model relates generally to small-sized infrared temperature measurement apparatus, is specifically related to a kind of small-sized infrared temperature measurement apparatus that iron and steel hot rolling line and/or floatation glass production line are used for accurately measuring steel band (or steel plate, excellent wire rod) surface and/or float glass surface true temperature.
Technical background
In the rolling mill practice in the steel production run, temperature of steel strips is a key process parameter, and it is directly connected to normally carrying out and product quality of production.For this reason roughing, the finish rolling of production line, treat warm area, laminar flow cooling, and coiling process the infrared radiation temperature point all is set, operating steel band is carried out contactless temperature-measuring, for temperature control system provides determination data.At the rolling on-the-spot thermometric of scorching hot steel band, must take safeguard measure to temperature instrumentation: the instrument probe unit must the installing cooling device, is cooled with circulating water protection and surveys components and parts, prevents that the infrared thermometer components and parts are overheated and causes temperature measurement error; Purge camera lens and light path with pressurized air, eliminate the contamination and the interference of steam, dust, reduce systematic measurement error.
The about 1200 ℃ slab that comes out from heating furnace by roughing mill rolling after, temperature is reduced to 900～1100 ℃ (invar kinds and different).After the roughing, the temperature that records is the data group of motion steel band length direction, can obtain steel band sampling spot temperature, the highest and minimum temperature, the highest and minimum temperature of head after data processing.The roughing temperature is except that setting for finish-rolling process, it shows the Temperature Distribution and the temperature difference of steel band intuitively at furnace operation chamber registering instrument temperature displayed curve, operating personnel adjust the burning process parameter in view of the above, as: fuel quantity, air-fuel ratio and the length of flame etc., the heating quality (tapping temperature and the temperature difference reach technical standard) of assurance slab.Finish rolling is gone into, outlet temperature signal need flow to computing machine, the thickness of combined belt steel, set and the control frame between be used to cool off the injection flow rate of the water jet of steel band, accommodation zone steel rolling acceleration makes the steel band finishing temperature reach desired value.Finishing temperature (steel band finish rolling outlet temperature) is different according to the difference of steel grade and thickness, and target setting value scope is about 800～900 ℃.The target temperature that batches of steel band is about 600～700 ℃ according to the difference of steel grade and thickness.The temperature of steel strips that comes out from mm finishing mill unit is approximately higher than about 200 ℃ of coiling temperature, need cool off on runout table, adopts laminar cooling system efficiently for this reason.Before coiling machine, measure temperature through cooled steel band with infrared thermometer.Steel band is reached batch target temperature.The method of control is PREDICTIVE CONTROL, compensation control and FEEDBACK CONTROL.PREDICTIVE CONTROL: finishing mill export goal temperature (predicted value), belt steel thickness and mill speed by computer settings, calculate injection flow rate, when band steel no show laminar flow cooling zone, promptly connect the part sparge pipe.Compensation control: after the band steel exported out from finish rolling, computing machine was connected a part of sparge pipe again according to the finish rolling outlet temperature that records.FEEDBACK CONTROL: the coiling temperature that computing machine records before according to coiling machine is adjusted injection flow rate with the difference of batching target temperature, to eliminate this difference.
In sum, in the rolling mill practice that steel are produced, roughing, finish rolling, treat warm area, laminar flow cooling, and coiling process the infrared radiation temperature point all need be set, to guarantee realizing control automatically in the production run.According to the metallography principle, rolling, cooling, link such as curl too high or too low for temperaturely can produce problems such as stress, crystallization, carbonide, iron scale.So that influence following process and steel performance.
