The invention provides a data processing method suitable for a seamless steel pipe, which specifically comprises the following steps as shown in figure 1:

step S1, a data processing method suitable for a seamless steel pipe is characterized by comprising the following steps:

the technical scheme provided by the invention is that the perforation is the most important forming process in the production of the hot-rolled seamless steel pipe, and the task of the perforation is to perforate a solid pipe blank into a hollow blank (hollow pipe). Machines for piercing tubular blanks are of various types due to their various construction, of which two-roll skew piercing machines are widely used. A general two-roll skew rolling puncher is composed of two barrel-shaped rolls arranged left and right, guide plate arranged up and down, and top pulled by a top trolley connected with a top rod. The roller is a main transmission external deformation tool and is mainly responsible for dragging a tube blank into the tube blank and perforating under the rolling of a certain rotating speed, and simultaneously performing rolling work such as wall reduction, surface flattening, uniform wall thickness, rounding and the like on the tube blank.

It is known that the two-roll cross-piercing body is provided with two rolls, which are named a first roll and a second roll. Continuously acquiring the pressure value of the first roller and the pressure value of the second roller, naming the acquired pressure value of the first roller as a first roller pressure value, and naming the acquired pressure value of the second roller as a second roller pressure value. And calculating the detected first roller pressure value and the second roller pressure value to obtain an average roller pressure value, comparing the average roller pressure value with a preset roller pressure value, and correspondingly generating first pressure early warning information if the average roller pressure value is greater than the preset roller pressure value. The preset roller pressure value is preset after the processor conducts statistics according to the historical roller average pressure values of the first roller and the second roller in the perforating machine. The comparison of the average pressure value of the roller with the preset roller pressure value has the effect that the corresponding fusion pressure coefficient is conveniently calculated according to the first pressure early warning information generated correspondingly in the follow-up process.

In a possible embodiment of the technical solution provided by the present invention, as shown in fig. 2, step S1 specifically includes:

step S1.1, respectively acquiring a first roller pressure value of a first roller and a second roller pressure value of a second roller through a roller pressure sensor, and adding the first roller pressure value and the second roller pressure value to obtain a roller pressure total value;

And respectively acquiring a first roller pressure value of the first roller and a second roller pressure value of the second roller through the roller pressure sensors, adding the first roller pressure value and the second roller pressure value, and summing to obtain a roller pressure total value.

S1.2, dividing the total pressure value of the rollers by the number of the rollers to obtain an average pressure value of the rollers;

according to the technical scheme provided by the invention, the total value of the roller pressure obtained by adding the first roller pressure value and the second roller pressure is divided by the number of the rollers, so that the number of the rollers is two, and the average pressure value of the rollers is obtained after the division. The average pressure value of the rollers needs to be calculated because in the actual production process, when the tube blank is rolled, the pressure values of the first roller and the second roller may have certain deviation and different conditions due to different thickness degrees and quality degrees of the tube blank, so that the first roller pressure value of the first roller and the second roller pressure value of the second roller need to be summed and averaged to obtain a relatively accurate average pressure value of the rollers, and the accuracy of data is ensured.

The average pressure value of the roll is calculated by the following formula,

the pressure value of the first roller is the pressure value,

at the second roll pressure value, roller _QTY RoP for number of rolls _gam Is a roll pressure gradient parameter;

according to the technical scheme provided by the invention, the pressure value of the first roller

And the pressure value of the second roller

Total value of roll pressure

Roller number of Roller _QTY Is divided by the preset roller pressure gradient parameter RoP _gam Adjusting to obtain the average pressure value of the roller

The pressure gradient parameter RoP of the roller _gam Is artificially preset and has an average pressure value according to the difference of the material and the thickness of the tube blank

Different, corresponding roll pressure gradient parameter RoP _gam Different. The harder the material of the blank tube and the coarser the blank tube, the average pressure value of the roll

The larger the corresponding roll pressure gradient parameter RoP _gam Adjusting the pressure of the roller to be smaller

According to the technical scheme provided by the invention, the average pressure value of the roller is compared with the preset roller pressure value, and if the average pressure value of the roller is greater than the preset roller pressure value, first pressure early warning information is correspondingly generated. The preset roller pressure value is preset after the processor conducts statistics according to the historical roller average pressure values of the first roller and the second roller in the perforating machine. The comparison of the average pressure value of the roller with the preset roller pressure value has the effect that the corresponding fusion pressure coefficient is conveniently calculated according to the correspondingly generated first pressure early warning information in the follow-up process.

According to the law of minimum resistance to plastic flow of metals, the amount of enlargement of the capillary (particularly of the thin-walled tube) is very large without the guide plate limiting effect, in which case the perforation process is difficult to achieve.

It is known that the two-roll cross-piercing body is provided with two guide plates, which are named first guide plate and second guide plate. Continuously acquiring the pressure value of the first guide plate and the pressure value of the second guide plate, naming the acquired pressure value of the first guide plate as a first guide plate pressure value, and naming the acquired pressure value of the second guide plate as a second guide plate pressure value. And calculating the detected first guide plate pressure value and the detected second guide plate pressure value to obtain a guide plate average pressure value, comparing the guide plate average pressure value with a preset guide plate pressure value, and if the guide plate average pressure value is greater than the preset guide plate pressure value, correspondingly generating second pressure early warning information. The preset guide plate pressure value is preset after statistics is carried out on the historical guide plate average pressure values of the first guide plate and the second guide plate in the perforating machine by the processor. The guide plate average pressure value is compared with the preset guide plate pressure value, so that the corresponding fusion pressure coefficient can be conveniently calculated according to the correspondingly generated second pressure early warning information.

And respectively acquiring a first guide plate pressure value of the first guide plate and a second guide plate pressure value of the second guide plate through the guide plate sensor, adding the first guide plate pressure value and the second guide plate pressure value, and summing to obtain a guide plate pressure total value.

S2.2, dividing the total pressure value of the guide plates by the number of the guide plates to obtain an average pressure value of the guide plates;

according to the technical scheme provided by the invention, the total guide plate pressure value obtained by adding the first guide plate pressure value and the second guide plate pressure is divided by the number of the guide plates, so that the number of the guide plates is two, and the average guide plate pressure value is obtained after the division. The guide plate average pressure value needs to be calculated because in the actual production process, when the tube blank is rolled, the pressure values of the first guide plate and the second guide plate have certain deviation and different conditions due to the difference of the thickness degree and the quality degree of the tube blank, so that the pressure values of the first guide plate and the second guide plate of the first guide plate need to be summed and averaged to obtain a relatively accurate guide plate average pressure value, and the accuracy of data is ensured.

The guide plate mean pressure value is calculated by the following formula,

wherein the content of the first and second substances,

The guide plate pressure gradient parameter GuP _gam Is artificially preset and has average pressure value of the guide plate according to the difference of the material and the thickness of the tube blank

Different, corresponding guide plate pressure gradient parameter GuP _gam Different. If the material of the tube blank is harder and the tube blank is thicker, the average pressure value of the guide plate

The larger the corresponding guide plate pressure gradient parameter GuP _gam Adjusting the pressure to the average pressure value of the guide plate

Compensating to obtain average pressure value of guide plate

Will not be too large. Conversely, if the material of the tube blank is softer and the tube blank is finer, the average pressure value of the guide plate is higher

The preset guide plate pressure value is preset after statistics is carried out on the historical guide plate average pressure values of the first guide plate and the second guide plate in the perforating machine by the processor. The guide plate average pressure value is compared with the preset guide plate pressure value, so that the corresponding fusion pressure coefficient is conveniently calculated according to the second pressure early warning information generated correspondingly in the follow-up process.
