According to the anti-pock amorphous crystallizer provided by the embodiment of the invention, the problems that the quality of a strip is seriously affected by pocks appearing on a copper roller sometimes when the strip is produced in an amorphous strip production process and that process personnel can also be forced to intensify polishing to accelerate the consumption of the copper sleeve of the crystallizer and then shorten the service life of the crystallizer are mainly solved; strips with various widths can be flexibly processed, and pocks are avoided.
Description
Technical field
The present invention relates to amorphous and manufacture field, relate in particular to a kind of anti-pit amorphous crystallizer.
Background technology
The amorphous crystallizer is a kind of wheeled crystallizer, in order to produce amorphous band.The core component of amorphous crystallizer is copper sheathing, and core technology is waterway structure.The classical architecture of crystallizer is a kind of structure of mosaic, and rotating shaft is inlayed copper sheathing outward, and in copper sheathing, several rectangular channels of Zhou Kaiyou are convenient to the cooling water circulation for connecting cooling water channel, and rotating shaft generally adopts the 45# steel, and copper sheathing generally adopts chromium zirconium copper or beryllium copper.Existing crystallizer in use, easily pit occurs at the edge of band overlay area, traces it to its cause, and is excessive the causing of edge's axial-temperature gradient of the band area of coverage.In this position, hot-fluid has two whereabouts: radial and axial.Wherein axial heat conduction is that band area of coverage middle part is unexistent, the closer to edge, more easily embodies the impact of axial heat conduction, has arrived band edge, and this impact will make the axial-temperature gradient of these positions be greater than centre position.Its result is exactly: thermograde is large, and stress is just large, and stress one is large, and the probability that goes out pit just increases greatly.Once pit occurs, will strengthen the difficulty of online reconditioning, if reconditioning can not be eliminated pit, the amorphous band of ejection will be scrapped so.
Summary of the invention
The object of the present invention is to provide a kind of anti-pit amorphous crystallizer, to solve crystallizer, used roll surface in horizontal stroke the problem of pit to occur.
The embodiment of the present invention provides a kind of anti-pit amorphous crystallizer, it comprises: rotary support, copper sheathing, be provided with the copper sheathing tank between described copper sheathing and rotary support, be provided with copper sheathing water route adjusting device between described copper sheathing support and described copper sheathing, described copper sheathing water route adjusting device further comprises the copper sheathing regulating block be connected on described copper sheathing and is connected to described rotatably supported rotary core regulating block.
Preferably, described copper sheathing regulating block has the first width, and half of the difference of the width of the band that described the first width is described copper sheathing width and planned production adds 3 millimeters.
Preferably, described rotary core regulating block has the second width, and the width of the band that described the second width is planned production, deduct the twice of the degree of depth of copper sheathing tank, then deducts the twice of 3 millimeters.
Preferably, the material of described copper sheathing regulating block is chromium zirconium copper or beryllium copper, and the material of described rotary core regulating block is the 45# steel.
The anti-pit amorphous crystallizer that the embodiment of the present invention provides, in the amorphous band production process, when producing band, pit appears on the copper roller sometimes, have a strong impact on the quality of band, also can force the technologist to strengthen the reconditioning dynamics simultaneously, make the depletion rate of crystallizer copper sleeve increase, shorten crystallizer service life.Can tackle flexibly the band of various width, and can not guarantee pit.
The accompanying drawing explanation
Fig. 1 is the structural representation according to a kind of anti-pit amorphous crystallizer of the embodiment of the present invention;
Fig. 2 is the generalized section according to a kind of anti-pit amorphous crystallizer of the embodiment of the present invention.
The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Fig. 1 is the schematic diagram according to a kind of anti-pit amorphous crystallizer of the embodiment of the present invention, as depicted in figs. 1 and 2, it comprises: rotary support 2, copper sheathing 1, be provided with copper sheathing tank 3 between described copper sheathing 1 and rotary support 2, be provided with copper sheathing water route adjusting device between described rotary support 2 and described copper sheathing 1, described copper sheathing water route adjusting device further comprises two the copper sheathing regulating blocks 11 that are connected on described copper sheathing 1 and the rotary core regulating block 21 that is connected to described rotary support 2.The material of described copper sheathing regulating block 11 is chromium zirconium copper or beryllium copper, and the material of described rotary core regulating block 21 is the 45# steel.
Described copper sheathing regulating block has the first width, and half of the difference of the width of the band that described the first width is described copper sheathing width and planned production adds 3 millimeters.
Described rotary core regulating block has the second width, and the width of the band that described the second width is planned production, deduct the twice of the degree of depth of copper sheathing tank, then deducts the twice of 3 millimeters.
The principle of the embodiment of the present invention is, by reducing the thermograde of edge, the pit caused by radial symmetry gradient, by reducing the radial heat flows density at strip edge place, can force edge's cooling velocity to slow down and the temperature of edge raises.The temperature contrast at the temperature of edge and center will diminish like this, makes thermograde descend.
Generally, will there be the large thermograde zone of 3mm at the edge of the band area of coverage, so the copper sheathing regulating block must guarantee that the wide zone of 3mm does not have water to flow through under the band footprint edges.And the width of rotary core copper billet should equal strip width to deduct 6mm, then deduct the degree of depth of two copper sheathing tanks.
In one embodiment, after the crystallizer installation, the wide band of plan spray 142mm.The overall width of crystallizer copper sleeve is 220mm, tank is 10mm deeply, so the width=3+ of copper sheathing regulating block (220-142)/2=42mm, the width=142-3*2-10*2=116mm of rotary core regulating block, after installation and debugging complete, produced, pit does not appear in the copper roller, thickness of strip 28 μ m, and the lamination coefficient is greater than 86, iron loss is less than 0.19, and strip quality is good.
The anti-pit amorphous crystallizer that the embodiment of the present invention provides, in the amorphous band production process, when producing band, pit appears on the copper roller sometimes, have a strong impact on the quality of band, also can force the technologist to strengthen the reconditioning dynamics simultaneously, make the depletion rate of crystallizer copper sleeve increase, shorten crystallizer service life.Can tackle flexibly the band of various width, and can not guarantee pit.
The above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only the specific embodiment of the present invention; the protection domain be not intended to limit the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
