Description
Technical field
The present invention relates to metallurgical industry production, more particularly, the present invention relates to a kind of locating and detecting device of flame cutting machine burning torch starting point.
Background technology
At present, when in metallurgical production, adopting flame cutting machine cutting high temperature billet steel, in order to save clipping time, to reduce the energy resource consumption of cutting, after the instruction of flame cutting operation provides, at first require burning torch to navigate to the edge of steel billet rapidly and accurately, the cutting combustion gas of opening burning torch then at once begins the steel billet cutting.
Reach above-mentioned requirements, key is how to obtain the lateral attitude of the edge of high temperature billet steel to be cut with respect to burning torch.Theoretically, can realize the rim detection of steel billet by the means of multiple electric detection.Yet, for high temperature billet steel, also do not have a kind of online electric checkout gear can reliablely and stablely realize the rim detection of high temperature billet steel (as about 1300 ℃).
Especially steel rolling production-line of some production lines is arranged, have plurality of devices (disconnected cut, disc type saw and flame cutting machine) to can be used to finish the cutting of steel billet usually as blocking.But, take all factors into consideration from the aspects such as floor space, cost of investment, operating cost and operational reliability of cutting equipment, under the situation that satisfies production technology rhythm, adopting flame cutting machine cutting steel billet is a kind of optimal selection.Yet because process equipment can't guarantee that the horizontal stand of every high temperature billet steel on the residing steel billet rollgang of flame cutting machine is roughly constant; There is not a kind of reliable and stable high temperature billet steel edge detecting device available, so many factories have to adopt that card is disconnected cuts or saw is finished the high temperature billet steel cutting yet.But also some production line is because of the restriction of space and steel billet shape, should not adopt that card is disconnected to be cut or saw carries out the cutting of high temperature billet steel, can only use flame cutting machine.Like this, horizontal stand on rollgang is roughly constant if process equipment can't guarantee steel billet, when also the location, steel billet edge of burning torch is manually controlled in inconvenience simultaneously, in this case, common specification and length according to the cutting steel billet, design the long pneumatic or hydraulically powered ambulatory splint of a number rice at the pairing roll segments of flame cutting machine, each steel billet vertically locates postpone on roller-way, this ambulatory splint laterally promotes steel billet towards the flame cutting machine direction, until the lateral edges and the snap of roller-way side shield of steel billet.Yet the use of this ambulatory splint has not only increased investment and the operation and the maintenance cost of Flame-cutter skill equipment, and has increased the operating time of Flame-cutter skill, thereby has reduced the effective operation rate of milling train.
The high temperature billet steel edge detecting device that present various flame cutting machine was equipped with all uses the detection principle of weight or copper pigtail ground connection to carry out the rim detection of high temperature billet steel.Yet, the burning slag that is spilt during owing to work under bad environment, temperature height and steel billet cutting with electric conductivity, weight that is equipped with or copper pigtail ground detection device can't reliablely and stablely be worked.High temperature makes insulating materials burn; Make the chain surface that hangs produce oxide layer, influence electric conductivity; Burning slag with electric conductivity may make the structure that needs insulation produce electric conduction phenomena again, sends rub-out signal.Especially for some steel billet cutting technique, in order to reduce burning torch transverse cuts starting point position error, require the as close as possible burning torch of weight or copper pigtail to install, the working environment of weight or copper pigtail ground detection device will be more abominable.Steel billet flame cutting machine in the flame cutting machine that is using on the sheet billet continuous casting flame cutting machine that the applicant uses, the middle plate sheet billet continuous casting line, the little H shaped steel before the mm finishing mill unit, these high temperature billet steel flame cutting machines provide by external professional flame cutting machine factory, and equipment all has the high temperature billet steel edge detecting device that ground connection weight or copper pigtail constitute when installing.But, many and be difficult to on-line maintenance or the like reason owing to checkout gear job insecurity, fault, cause the steel billet edge detecting device to be forced to stop using.
At present general technology status is: the steel billet edge detecting device that is made of ground connection weight or copper pigtail of online use is installed in the downstream of flame cutting machine usually, and keep on the continuous-casting of steel billet line of a determining deviation (this spacing is less than the steel billet cut lengths) (continuous casting steel billet temperature herein is generally below 600 ℃) with flame cutting machine, be used for the starting point control of continuous casting steel billet cut lengths counting, promptly when the continuous casting steel billet head is met this ground connection weight or copper pigtail in moving process, steel billet cut lengths counter begins counting, when rolling counters forward reaches the required count value of cut lengths, control system starts flame cutting machine, make its vertical and same moved further of continuous casting steel billet, transverse cuts continuous casting steel billet simultaneously.The ground connection weight steel billet edge detector that is used for the control of steel billet cut lengths that uses on 140 * 140 billet continuous casting line that uses as the applicant and the round billet continuous casting line etc., employing be exactly above-mentioned technology.Because no reliable and stable high temperature billet steel edge detecting device, the production line that great majority need flame cutting machine is the continuous casting billet production line especially, normally passes through the design and the adjustment of process equipment, makes the lateral attitude of continuous casting billet on the steel billet rollgang roughly constant.Like this, under the situation of no high temperature billet steel edge detecting device, flame cutting machine also can navigate to the edge of continuous casting billet to be cut more exactly.Yet, need the production line of flame cutting machine for some, owing to can't guarantee that the horizontal stand of every high temperature billet steel on the residing steel billet rollgang of flame cutting machine is roughly constant by the design and the adjustment of process equipment, so, before each steel billet cutting, need the operative employee manually to control the edge that the burning torch of flame cutting machine is navigated to steel billet.Usually, position for the ease of the artificial judgment burning torch, the operative employee must under the situation that the burning torch Cutting Gas is opened with burning torch from moving near the edge towards steel billet above the steel billet at steel billet edge, till the flame column of burning torch was suddenly elongated, the operative employee started the automatic cutting process of flame cutting machine then.Plate continuous casting slab secondary cut fire cutter was exactly to adopt the Artificial Control mode to finish the location, steel billet edge of flame cutting machine burning torch during the applicant was employed.
In sum, up to the present, also there is not the edge detecting technology of high temperature billet steel (about 1300 ℃) that can very desirable realization flame cutting machine.
