Background technology
It is quick, energy-conservation, efficient that eddy-current heating has, and is convenient to series of advantages such as automation, has been widely used in metallurgical industry as heating.In seamless steel tube production process, the thickening method of steel tube end part is utilized Frequency Induction Heating exactly three times, increases heated length gradually, carries out the jumping-up thickened steel-tube then.The general requirement of heating-up temperature before the steel pipe jumping-up is controlled at 1200 ℃, because how the length of Medium Frequency Induction Heating Furnace case accurately detects heating-up temperature between 800～1000mm, effectively controls heat time heating time and temperature, is directly connected to the end mass of seamless steel pipe.For many years, the method that the site operation personnel adopts is that steel pipe goes out behind the coil with the method for infrared appearance detected temperatures, has produced two problems that are difficult to avoid thus; One of which; It is far away to detect the about 10m of distance, adds upper surface and often has oxide skin, is difficult to accurately detect the actual temperature of steel pipe; Its two because the whole heating process of steel pipe can't online detection at any time temperature, cause the not enough or burning of steel pipe heating, influenced steel pipe thickening quality.Therefore, online accurate detection steel pipe heating-up temperature how, stable and improve the inherent quality of thickened steel-tube, be the difficult problem that the steel pipe's production technical staff is concerned about and need captures always, also be numerous operators expect.
With regard to thermometric, be a mature technique, and temp measuring method and device are of all kinds, but under hot conditions, think that accurate detected temperatures is very difficult.In the existing detection technique; Noncontact steel pipe inner wall temperature detection method and device 200610023412.2 and two patents of lever steel pipe inner wall temperature checkout gear ZL200520048051.8 are utilized distinct methods and device solves steel tube end part eddy-current heating temperature measurement on-line problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of steel tube end part inductive heating device with system for detecting temperature; This device is through on the casing of heating furnace, offering the temperature probe fixing port; Temperature probe extend into through the temperature probe fixing port in the inner chamber of induction coil near the position of steel tube end part, and the temperature of steel tube end part is carried out detecting in real time with accurately.
A kind of steel tube end part inductive heating device with system for detecting temperature; Comprise that casing, induction coil, coil water inlet pipe, coil outlet pipe are connected busbar with induction coil; Have the temperature probe fixing port on the described casing, temperature probe passes the temperature probe fixing port and stretches in the induction coil.
Described temperature probe fixing port is a pass, and the temperature probe fixing port is several, opens in order on casing; Have thermometer hole on the described induction coil; The position of thermometer hole is corresponding with the temperature probe fixing port, and the two ends of thermometer hole are equipped with cooling water nozzle leading-out end and are connected baffle plate with coil, and two cooling water nozzle leading-out ends are communicated with conduit; Temperature probe is with the temperature probe sleeve pipe outward, and temperature probe passes thermometer hole near steel tube end part.
The test point of described temperature probe is 10～100mm with the distance that is arranged in the steel tube end part of induction coil.
Described temperature probe fixing port comprises chute, and flange, external thread sleeve and clamp nut are housed on the chute, and temperature probe passes external thread sleeve and gets near steel tube end part from the turn-to-turn space of induction coil.
The test point of described temperature probe is 15～20mm with the distance that is arranged in the steel tube end part of induction coil.
Described temperature probe is the infrared optical fiber temperature probe.
The present invention offers a plurality of holes by certain position on the casing of steel tube end part thickening stove; Perhaps hole slot; Temperature probe is inserted in the hole the position on demand, and when steel pipe entering induction coil was heated, temperature probe got final product the detection at any time temperature; And import signal into transmitter through the fiber optic conduction line, directly show the measured temperature value through secondary meter; Because the shielding action of fiber optic conduction line, so detected temperature is to stablize glitch-freely, make the temperature signal curve smoothing of acquisition, accurately, guaranteed the stable of steel pipe thickening quality, can realize that closed loop controls automatically; And the present invention utilizes induction coil turn-to-turn crack and direct perforate that temperature probe is set, and when needs, just inserts temperature probe, has effectively protected fibre-optical probe not receive the long-term radiation of high temperature, has prolonged service life; The present invention is simple in structure, efficiently solves steel pipe thickening workshop section because of heating process can't accurately detect, and causes burning or heats problems such as not enough, and product quality is obviously improved, and application prospect is boundless.
