Embodiment one
Fig. 1 is a kind of flow diagram of electric radiant tube temprature control method in the embodiment of the present invention.As shown in Figure 1, this
Inventive embodiments provide a kind of electric radiant tube temprature control method, are applied to a vertical annealing furnace, which comprises
Step 110: acquisition obtains the current strip information in the vertical annealing furnace.
Specifically, acquiring the strip information processed in the current described vertical annealing furnace, the strip information is band
The indexs such as material, temperature, the model of steel are obtained the specific targets information of strip by system, obtain the temperature and strip of strip
Whether it is non-easy wooden dipper material, is heated in furnace and is cooling due to strip, since strip and furnace roller temperature difference of its contact increase,
It is also easy to produce wooden dipper song and sideslip and determines that the whether easy wooden dipper song of strip targetedly takes corresponding electric radiation to influence strip quality
Tube temperature is adjusted furnace roller temperature, avoids generating wooden dipper song, sideslip, material is important factor in order.
Step 120: according to the current strip information, determining the output limit of the electric radiant tube in the vertical annealing furnace
Width;Wherein, the electric radiant tube is used to be promoted the temperature of corresponding furnace roller.
Further, described according to the current strip information, determine the defeated of the electric radiant tube in the vertical annealing furnace
Clipping out specifically includes: according to the current strip information, judging whether the current strip is non-easy wooden dipper material;When described
When current strip is non-easy wooden dipper material, the output violent change for obtaining the electric radiant tube is the upper limit=0.
Further, described according to the current strip information, judge the current strip whether be non-easy wooden dipper material it
Afterwards, comprising: when the current strip is not non-easy wooden dipper material, obtain the electric radiant tube output violent change be the upper limit=
100%.
Specifically, according to the band steel material in strip information so that it is determined that electric radiant tube clipping information, due to the electricity
Radiant tube carries out the adjustment of furnace roller, the temperature difference is avoided to increase, hot strip touches cold furnace mainly for preventing wooden dipper song, sideslip
Roller two generates positive convexity effect, and is also easy to produce that wooden dipper is bent, sideslip, when it is described with steel material be to be not easy the material of wooden dipper song, then do not need
The adjustment of electric radiant tube is carried out, to set 0 for the electric radiant tube clipping information upper limit, that is, does not need to open electric radiant tube
Temperature adjustment is carried out, the electric radiant tube is without heating, so as to avoid the electric radiation for taking certain temperature regardless of material
Pipe is adjusted roller temperature, and the band steel material for being not likely to produce wooden dipper song still uses electric radiant tube, causes waste of energy.Work as band
When the material of steel is easy wooden dipper song material, set the upper limit as 100%, i.e. the temperature of electric radiant tube can be adjusted at random, maximum
To the maximum temperature value of the electric radiant tube, then specifically set according to the actual temp of its soaking zone, slow cooling section, rapid cooling section
Fixed, proportional relationship, belt steel temperature setting value is presented in the belt steel temperature in electric radiant tube tube temperature setting value and region setting at this time
Higher, electric radiation tube temperature setting value is higher, avoids temperature difference bigger than normal.Strip is obtained by the belt steel temperature in the strip information
In soaking zone, slow cooling section, the corresponding setting value of rapid cooling section, is specifically set by the actual temp of each roll segment, avoid system
One uses a kind of operating temperature, high wooden dipper style of song is nearly expected, the setting of electric radiant tube temperature is improper, and the temperature difference is too big, causes furnace roller roller
Negative convexity is presented in shape, and strip is easy in cold-zone sideslip, for example, for wide cut IF steel, the rapid cooling section strip steel temperature in production
Only 280 DEG C, according to electric radiant tube in the prior art, set temperature is 820 DEG C in the operating condition, and temperature is too high, with the width
The temperature difference of 280 DEG C of section of width IF steel rapid cooling is too big, is easy to cause furnace roller roller shape that negative convexity is presented, and strip is easy in cold-zone sideslip.
Step 130: acquisition obtains belt steel temperature setting value of the strip at currently processed section.
Further, the belt steel temperature setting value, comprising: soaking zone belt steel temperature setting value, slow cooling section belt steel temperature
Setting value and rapid cooling section strip steel desired temperature.
Specifically, be the material according to strip according to the strip information, it is corresponding each in the vertical annealing furnace
The temperature of roller room is different, when obtaining the strip information, can correspond to obtain the strip soaking zone belt steel temperature set
Definite value, slow cooling section belt steel temperature setting value and rapid cooling section strip steel desired temperature, wherein soaking zone is the previous of the slow cooling section
A processing section, the slow cooling section are the previous processing section of the rapid cooling section, i.e., according to treatment process, processing section sequencing is
Soaking zone, slow cooling section, rapid cooling section.Processing section locating for current strip is acquired, corresponding processing section desired temperature is obtained, is illustrated
For, when current strip is in the slow cooling section of the vertical annealing furnace, obtain the slow cooling section desired temperature of the strip.
Step 140: the belt steel temperature setting value according to the strip at currently processed section obtains the strip and locates currently
Manage the tube temperature temperature reference value of the electric radiant tube of section.
Further, the belt steel temperature setting value according to the strip at currently processed section, obtains the strip and exists
