Abstract
The invention relates to a preheating and/or annealing device for continuous casting metal blank, particularly used in linear material with large section. The device comprises a contact wheel and a guide wheel which are used in direct resistance heating for linear material. The linear material can be heated or annealed through the contact wheel and the guide wheel, in a manner of maximum protection and minimum flexural load and under the condition that the contact wheel and the guide wheel never slide up and down. At least two among the contact wheel, the guide wheel KR-[1], UR-[2], KR-[3], KR-[4], KR-[5] and departing wheel AR-[6] have spontaneous drive and form respectively a divided type driving machine set (8). The drive shafts (21, 22) are mutually aslant arranged with an angel of Alpha-[1] + Alpha-[2]. The circumferential speed of the contact wheel and the guide wheel cooperate with speed of each linear material through static and independent adjustment of torque.
Description
Be used for metal strand material, especially for the larger cross-section wire rod give heat and/or the annealed device be known, the driving of wheel trolley and guide deflection sheave thereby a kind of mechanical transmission of for example being settled by fixed in space by a total drive point in this class device achieves a butt joint, so once the revolution of Xuan Ding trolley wheel and guide deflection sheave relation has just been determined, promptly is immutable.
Yet will produce the wire rod elongation between continuous wire heating hour wheel and wheel, this elongation may be significantly different according to temperature height and material character.Common outlet temperature is about 500 ℃ to 550 ℃ when annealing for copper wires, raises and the elongation of the wire rod that causes therefrom can only be by to the calculating of transmission and bottom line compensates approx in each temperature of giving the interior generation of heat distance.Yet the error of desired outlet temperature or select a kind of other material wire will cause different wire rod elongations, like this, the circumferential speed of wire rod is just no longer consistent with the circumferential speed of trolley wheel and guide deflection sheave.As a result, wire rod is not unallowed elongation to be arranged and sometimes until overload is disrumpent feelings, be exactly this wire rod can more or less skid by trolley wheel and guide deflection sheave, this just impels the wire rod vibration to increase, thereby has increased the formation of electrical spark.
This situation causes the wire surface loss that can't estimate and the wearing and tearing that increase trolley wheel, can cause unallowed spark to disturb in addition.
For this reason, task of the present invention is to propose one at the device that begins to speak of, and wire rod gives heat or annealing in the mode of protection as far as possible in minimum bend load with under nonslipping condition on trolley wheel and the guide deflection sheave in this device.
This task characteristic by claim 1 in this class device solves.
Some favourable structures of apparatus of the present invention comprise in the dependent claims.
