Description
Technical field
The present invention relates to temperature measuring equipment and preparation method thereof, specifically belong to cutting and preparation method for the experiment of bell furnace inserted sheet.
Background technology
The experiment of bell furnace inserted sheet mainly is applied to the following aspects, and whether the first has reached designed capacity for the bell furnace engineering provides FAT (Factory Acceptance Test) test in order to the actual capacity of checking stove; It two is to provide Data support for the cover annealing correction of the model; It three is whether check stove existing annealing process has satisfied the requirement of technique, otherwise is also the effective means that existing annealing process is optimized.
In order accurately to measure the temperature changing trend of annealing coil core and limit section in bell furnace, need thermopair is embedded to the specified location of coil of strip, and the effect of transplanting a cutting is exactly to batch at coil of strip the inside that current events are first inserted coil of strip, prop up a certain size gap, can easily thermopair be inserted the measuring point of appointment along the fluting of transplanting a cutting when the coil of strip shove charge.Therefore, whether the cutting design rationally has great impact to the precision of testing.
In addition, in order not affect production, the lab rolls of using in reality is all generally to produce volume, can produce infringement and place the surface quality of transplanting a cutting to coil of strip (the particularly low coil of strip of carbon content) in coil of strip, pars affecta branch cuts off in the operation of back, thereby has reduced the lumber recovery of finished product volume.
Thereby as the cutting of one of several main supplementary unit of bell furnace inserted sheet experiment, the quality of its design and manufacture quality not only can have influence on the accuracy of experiment, also can have influence on the lumber recovery of coil of strip.
Before the present invention, general random being made of inserted sheet experiment cutting used, use and have many deficiencies: as when the length of transplanting a cutting is long, cause to carry out secondary treatment in use, soon its redundance cuts or is crooked, can to the steel roll rim injury, even can produce safety problem when dealing with improperly; The thickness of transplanting a cutting is blocked up or cross when thin, can produce thermopair and place unstable or slotting not in place and accuracy that impact is measured, can't instruct the annealing process of bell furnace; When the thermopair socket depth out of true of transplanting a cutting, can cause equally thermopair to place unstable or slotting not in place and accuracy that impact is measured; Due to unreasonable structure, lay that when transplanting a cutting, traction rope easily comes off, cause transplanting a cutting after landing and can not be well to put into coil of strip along coil of strip axially parallel ground, cause thermopair to be difficult to accurate buried measurement point to appointment.In addition, due to any processing is not carried out in limit section and the bight of transplanting a cutting, the corner angle at these positions very easily cause the surface quality problems such as cross break seal and scuffing to the sandwich tape steel around it, affect the lumber recovery of coil of strip.
