Abstract
The utility model relates to a continuous casting crystallizer copper plate, wherein, 10 thermocouple holes and a positioning key slot are additionally formed in two rows at the lower part of the copper plate. After the copper plate rotates 180 degrees around the plane of the copper plate, the additional thermocouple holes and the positioning key slot at the lower part coincide with the thermocouple holes and the positioning key slot which are formed at the upper part before the rotation. When a hot crack appears on the upper part of the copper plate, the cracked upper part and the uncracked lower part of the copper plate can change positions with each other. When a crack appears on the upper part of the copper plate, which is the uncracked lower part of the copper plate before the exchange, the copper plate is dismounted to be planed, so that the copper plate is planed less frequently, and the service cycle of the copper plate is increased by over 30 percent. Therefore, not only the cost of spare parts is reduced, but also the workload of disassembly, assembly and planning is reduced.
Description
Technical field
The utility model belongs to the continuous casting installation for casting field, is specifically related to the long-life copper coin that a kind of continuous cast mold is used.
Background technology
At present, domestic conticaster adopts the straight plate crystallizer of combined type mostly, and top two rows of copper coin front surface are provided with 10 thermocouple holes and 1 positioning spline, wherein have 6 thermocouple holes to occupy copper coin center line left side, and 4 are in copper coin center line right side in addition; Positioning spline then is positioned at the position of copper coin center line right side and close center line.
High-temperature molten steel is in crystallizer in the process of setting, copper coin is under the condition of the static pressure of molten steel and cooling water and cold and hot fatigue always, also be subjected to the high-temperature oxydation of molten steel simultaneously, wash away and chemical attack repeatedly, in throwing, vibration processes, produce the variation of wearing and tearing accordingly, deteriorate.Therefore the fire check defective often appears in the copper coin surface, and concentrates on mostly apart from the copper coin upper edge that 80 mm places are the slag line place, and other position crackles are very little even do not have a crackle; Crackle is not then seen in the copper coin bottom.Separate crystal crystallizer copper coin is carried out planing operation in order to remove the fire check of slag line position, copper coin top fully, need to roll off the production line.But be subjected to the copper coin structural limitations, must plane to whole copper coin surface during planing operation, because copper plate thickness is limited, the thickness that can plane only has 12 mm, promptly reach retiring thickness after the planing several times, thereby greatly reduced the reparation number of times and the service life of copper coin, both increased the workload of maintenance processing, strengthened the spare part deposit and the expense expenditure of copper coin again.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple in structure, is convenient to processing and fabricating, can effectively reduce surface planing number of times, has the continuous casting crystallizer copper plate than the long life.
Its concrete solution is:
A kind of continuous casting crystallizer copper plate is set up two rows totally 10 thermocouple holes and a location in the bottom of copper coin
Keyway, behind copper coin Rotate 180 °, thermocouple hole that the bottom is set up and positioning spline and the corresponding coincidence in the position of original thermocouple hole of rotation front upper part and positioning spline.Set up a fixing keyway in the backboard bottom of copper coin.
The beneficial effects of the utility model are:
When fire check appears in copper coin top, can not plane, but with the transposing of copper coin top and bottom, the copper coin top that is about to occur crackle is transposed to the bottom, and will not have the bottom transposing of crackle to be top.Because molten steel has formed the base shell when arriving the copper coin bottom, even the bottom exists slight fire check also can not influence normal use.When the copper coin top after using transposing also crackle occurs, copper coin is rolled off the production line carry out planing operation again, fire check is removed continued to use.Because upper and lower thermocouple hole and positioning spline number equate and the position is corresponding, so very easily transposing, thus the planing number of times of copper coin reduced relatively, make the life cycle of copper coin improve more than 30%, when reducing the spare part expense, reduce the workload of dismounting and planing operation.
Description of drawings
Accompanying drawing is the continuous casting crystallizer copper plate structural representation.
Among the figure: original thermocouple hole 1, original positioning spline 2, bolt hole 3, new thermocouple hole 4, new positioning spline 5.
The specific embodiment
By the continuous casting crystallizer copper plate structural representation as seen, the surface of copper plate of crystallizer is evenly equipped with a plurality of bolts hole 3, the utility model divides two rows to set up 10 new thermocouple holes 4 and 1 new positioning spline 5 again in the bottom of copper coin on the basis that keeps the top two original thermocouple holes 1 of row and original positioning spline 2.Because original thermocouple hole 1 and original positioning spline 2 are not symmetric arrangement, therefore in order to guarantee to change up and down the position correspondence of metapore and groove, so the position of new thermocouple hole 4 that the bottom is set up and new positioning spline 5 must guarantee to overlap fully with the position that rotates the original thermocouple hole 1 of front upper part and original positioning spline 2 behind self plane Rotate 180 ° when copper coin.According to needs are installed, on copper coin backboard bottom and top correspondence position, set up a fixedly keyway simultaneously.
Claims (2)
1. continuous casting crystallizer copper plate, it is characterized in that, set up two rows totally 10 thermocouple holes and a positioning spline in the bottom of copper coin, behind copper coin Rotate 180 °, thermocouple hole that the bottom is set up and positioning spline and the corresponding coincidence in the position of original thermocouple hole of rotation front upper part and positioning spline.
2. continuous casting crystallizer copper plate according to claim 1 is characterized in that, a fixing keyway is set up in the backboard bottom of described copper coin.
