Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel pipe production temperature measuring equipment, and particularly relates to a device based on single-station measurement of pipe blank piercing temperature. BACKGROUND

[0002] At present, seamless steel pipes are usually produced by hot rolling piercing, and the high-temperature pipe blank is taken out from the annular furnace and transported to the piercing machine. Under the combined action of the roller and the top head, a conical cavity is formed in the middle part of the pipe blank. The piercing temperature of the pipe blank should be controlled within a certain range to ensure the plastic deformation capacity of the pipe blank and the safe and stable operation of the equipment. During the piercing process, the broken iron oxide skin will splash everywhere, causing the temperature measuring personnel to be exposed to certain high-temperature radiation and posing a certain safety hazard. Considering the production cost factor, most enterprises indirectly calculate the piercing temperature of the pipe blank according to the tapping temperature and temperature drop time of the pipe blank. Under normal circumstances, there will be a small deviation between the calculated piercing temperature and the actual piercing temperature of the pipe blank. Therefore, it is necessary to develop a relatively economical device for measuring the piercing temperature of the pipe blank.

[0003] After searching, three patent documents were found to be most relevant to the utility model technology, and the specific contents are described as follows:

The cutting device, the cutting device, the centering device, the hot piercing machine and the cooling device are connected in sequence to form a production line, so that each processing link of the steel pipe is connected to form a complete processing system, which can improve the production efficiency of the steel pipe. However, the device only designs a billet pipe hot piercing production line, and does not actually measure the actual temperature of the billet pipe during piercing.

[0005] Patent document CN201911053163.5 discloses a steel rod temperature monitoring and sorting device for stainless steel rod high-temperature piercing process, which mainly includes a temperature sensor, a steel rod sorting unit, a steel rod recycling unit, a controller and a computer. The device is designed with exquisite design and ingenious design. The real-time temperature measured by the temperature sensor is input into the program through the converter, and the outside room temperature interference is excluded through a series of algorithms to obtain the temperature of the steel rod tapping. The device has relatively high automation degree and relatively high measurement accuracy, and can automatically sort unqualified steel rods without stopping. However, the device can only measure the temperature of the stainless steel rod during conveying, and cannot actually measure the actual temperature of the stainless steel rod during piercing.

[0006] Patent document CN201610463146.9 discloses a manufacturing method of seamless steel pipe piercing plug and a temperature control system thereof, which mainly comprises designing chemical composition of an ingot, pre-forging the ingot into a round steel, heating the round steel, die forging the round steel into a blank, heat preservation and cooling of the blank, and nitriding treatment of the product, and the manufacturing method can realize the piercing plug to meet the necessary rigidity of piercing while having good forgeability, and can improve the density, strength and wear resistance of the product, thereby prolonging the service life of the product.
