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.

Stating roller room number is when preliminary roller room is number i.e. which roller room where pushing up bottom roller room, and the roller number of chambers amount is the cooling section furnace
The quantity of roller room, the belt steel temperature setting value are according to the corresponding soaking zone obtained of belt steel temperature in strip information, slow cooling
Section, the belt steel temperature setting value of rapid cooling section.The tube temperature temperature reference value, each roller room situation i.e. roller number of chambers that last basis obtains
Amount, number etc., in conjunction with the electric radiant tube clipping information, the desired temperature of the previous processing section of the processing section is calculated separately respectively
The electric radiant tube desired temperature of roller room.Wherein, the electric radiant tube desired temperature of slow cooling section, the band according to strip in slow cooling section
Steel temperature sets corresponding tube temperature temperature reference value, according to the Position Number where the bottom roller room of top, before the slow cooling section
One processing section is soaking zone, thus is set in conjunction with soaking zone belt steel temperature by calculated result, for non-easy wooden dipper material
Strip is limited to 0 thereon, then the equal setting value of its temperature is 0, that is, does not have to be heated using electric radiant tube.The electric radiation of rapid cooling section
Pipe desired temperature, the belt steel temperature according to strip in rapid cooling section set corresponding tube temperature temperature reference value, according to top bottom roller room
The Position Number at place is set in conjunction with the belt steel temperature of its previous processing section slow cooling section according to formula calculated result, equally
For non-easy wooden dipper material, be 0 DEG C.For example, the tube temperature temperature reference value calculated result of slow cooling section is 920 DEG C, slow cooling
Totally 2 each roller rooms, soaking zone set temperature are that 780 DEG C of slow cooling section set temperatures are 600 DEG C to section, second each roller room electric radiation of slow cooling section
Pipe desired temperature Ts-tube-2=min (2* (760-600)/2+920,820)=min (1080,820)=820 DEG C.Pass through
It takes dynamic to adjust the mode of electric radiant tube desired temperature, guarantees furnace roller temperature, not because the variation of roller shape causes strip in furnace
Interior wooden dipper song, sideslip, so that it is fixed for solving electric radiant tube desired temperature in the prior art, it is a kind of under production model
Temperature is not able to satisfy the technical issues of production needs, while having reached and having guaranteed not because the variation of roller shape causes strip in furnace
Wooden dipper is bent, in the case where sideslip, and dynamic carries out temperature setting, avoids and is consistent high temperature and works, causes waste of energy
