The method according to this invention so solves above-mentioned purpose, in order to make band top layer spalling, after the cross section sclerosis of watering casting from its longitudinal axis make its on both direction through repeatedly alternating bending, make the superficial layer spalling thus and the removing of the superficial layer of spalling made smooth surface through following.By utilizing the action direction opposite curvature process of being advised to carry out the crisp top layer spalling that mechanism makes the band both sides on the casting top layer, with the abrasion device it is removed at last watering.
The present invention also provides a kind of device that is used to implement said method, sclerosis water casting (3) after leaving apparatus for pouring through repeatedly turn to round staggering mutually, water the adjustable buckling roller of casting (3) (4) relatively and be directed, be used for mechanically or device (5) that the top layer of spalling is removed on hydraulic machinery ground is arranged at the back of buckling roller (4).If another suggestion according to the present invention is provided with a buckling roller that is heated to the band temperature, just then can not produce temperature loss in band according to process of the present invention.
To be used to remove the device that waters casting spalling top layer and be designed to the brush that corrasion is rotated, the height of its rotating speed and relative belt surface is adjustable.This brush preferably can be along the top layer of rotating and mechanically removing spalling with band side in the opposite direction.
In another kind of modification, will be used to remove the device that waters casting spalling top layer and be designed to charge into hot water or vapours, adjustable drive nozzle, the material removal that utilizes this nozzle can will become flexible from the surface of band economically equally according to of the present invention.Utilization preheats medium can reduce thermal losses in the band.
In a kind of favourable structure of the present invention, be provided with one and be used to adjust the self-checking device that desire is removed skin depth, in this device, make cast carrying material constant, cast tape thickness and tape running speed be for providing parameter, and in wherein passing to corresponding driving device or valve again according to the signal of the rotating speed high-pressure medium pressure of the insert depth of measured surface quality formation buckling roller and/or brush and with it.
At last, in the favourable modification of another kind of the present invention, the device that buckling roller and being used for is removed the top layer is arranged on the housing of a sealing, and removed skin-material is received in this housing and can be used further to water in the melting process of casting.
Compared with prior art has a series of advantage according to apparatus and method of the present invention.At first given prominence to the economy of method, this is because the material of removing from belt surface seldom and with the actual bed thickness that will remove adapts.This will obviously reduce in the prior art owing to remove the material consumption that thick layer of material produced, thereby make this efficiency of equipment be able to obvious raising.Next is the cooling that the device being used for removing the top layer having avoided being bound in the prior art run into waters casting, and in addition, the quality of belt surface is corresponding with desired quality in the operation of rolling.Whole device simple in structure and very effectively and by making the economy of this equipment further improve again to the utilizing again of surfacing of being removed.
