Embodiment 1

[0034] Such as figure 1 with figure 2 As shown together, an acid-free descaling and slitting combined unit includes an uncoiler 1, a first pinch steering roller 2, a straightener 3, an inlet shear 4, a first centering mechanism 5, and a descaling Box 6, drying box 7, surface detection device 8, second centering mechanism 9, first looper 10, third centering mechanism 11, pinch roller 12, slitting shears 13, second looper 14, outlet Shear 15, tensioner 16, oiler 17, second pinch turning roll 18 and winder 19, preferably one side of slitting shear 13 is also provided with waste edge coiler 130.

[0035] Uncoiler 1: used to open the steel coil and send the steel plate 20 to the first pinch turning roller 2;

[0036] The first pinch turning roller 2: used to turn the bent steel plate 20 from the uncoiler 1 into the straightener 3;

[0037] Straightening machine 3: used for straightening the bent steel plate 20;

[0038] Entrance scissors 4 and exit scissors 15: cut off the hea...

Embodiment 2

[0054] An acid-free descaling method, comprising the following steps:

[0055] Step 1: Start the driving mechanism to drive the support plate 141 on the first looper 10 and the second looper 14 to swing upwards. At this time, the two support plates 141 are in a horizontal state, and the steel plate 20 will not enter the concave hole under the action of the support plate 141. pit;

[0056] Step 2: Push the slitter 13 out of the working area, and the slitter 13 is not put into work;

[0057] Step 3: The uncoiler 1 unrolls the hot-rolled steel coil for feeding, the steel plate 20 enters the straightening machine 3 through the first pinch turning roller 12, enters the descaling machine through the entrance shear 4, the first centering mechanism 5, and the entrance grating 60 Box 6, after descaling and cleaning in the descaling box 6, a clean steel plate 20 without scales is obtained, and then enters the drying box 7 through the exit grating 61, and the surface of the steel plate ...

Embodiment 3

[0065] A combined acid-free descaling and slitting method comprising the steps of:

[0066] Step 1: Set the descaling box 6, the drying box 7, the surface detection device 8, the oiler 17 and the slitting shears 13 to the working state;

[0067] Step 2: Start the driving mechanism to drive the support plate 141 on the first looper 10 and the second looper 14 to swing downwards to avoid the pit;

[0068] Step 3: The uncoiler 1 unrolls the hot-rolled steel coil for feeding, the steel plate 20 enters the straightening machine 3 through the first pinch turning roller 12, enters the descaling machine through the entrance shear 4, the first centering mechanism 5, and the entrance grating 60 Box 6, after descaling and cleaning in the descaling box 6, a clean steel plate 20 without scales is obtained, and then enters the drying box 7 through the exit grating 61, and the surface of the steel plate 20 is removed by squeezing and blowing in the drying box 7. After the water is removed, ...

Abstract

The invention discloses an acid-free descaling and longitudinal cutting combined unit and a production method thereof, and relates to the technical field of jet descaling, the acid-free descaling and longitudinal cutting combined unit comprises an uncoiler, a descaling box, a drying box and a coiler which are arranged in sequence, and a longitudinal cutting shear is further arranged between the drying box and the coiler; a first loop and a second loop are arranged between the drying box and the longitudinal cutting shear and between the longitudinal cutting shear and the winding machine respectively, each of the first loop and the second loop comprises a sleeve body, a downward pit is formed in each sleeve body, and supporting plates and driving mechanisms for driving the supporting plates to swing are arranged on the two sides of each sleeve body in a swinging mode; continuous descaling and longitudinal cutting slitting of the hot-rolled wide steel coil are achieved, the narrow-specification striped steel coil which is clean in surface and free of scale residues and has the width specification meeting the downstream use requirement is finally obtained, various subsequent forming machining requirements are met, the equipment occupied area is small, the production cost is low, the metal utilization rate is increased, and the production cost is reduced. The steel coil is prevented from being damaged due to frequent uncoiling and coiling, and the steel coil manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of jet descaling, in particular to an acid-free descaling and slitting unit and a production method thereof. Background technique [0002] During the production and processing of commercial vehicle beams, the raw materials used are hot-rolled wide steel coils, which need to be slit to obtain slits of appropriate width to meet the requirements of subsequent stamping or rolling. At the same time, the iron oxide scale on the surface of the hot-rolled sheet must be removed before the final coating, in order to obtain the ideal coating quality and anti-corrosion effect. In the current conventional production process, the slitting and slitting of hot-rolled wide coils and the removal of surface oxide scale are carried out in two independent units. The hoisting and turnover of materials is cumbersome, and frequent uncoiling and rewinding will cause bumps and scratches on the head and tail of the steel coil, result...
