Description
The technical field is as follows:
the invention belongs to the technical field of double-roller thin-strip continuous casting, and particularly relates to a method and a device for cleaning a double-roller thin-strip continuous casting roller surface. .
The background art comprises the following steps:
the typical production process of the twin-roll thin strip continuous casting technology comprises the following steps: molten steel is uniformly distributed in a space surrounded by two casting rolls which rotate oppositely and are cooled by water and a baffle plate made of ceramic material to form a molten pool, the molten steel is solidified on the roll surfaces, and thin strip steel is rolled between the two casting rolls. The double-roller thin-belt casting and rolling process cancels a series of conventional procedures of continuous casting (also known as ingot casting), rough rolling, hot continuous rolling and related heating, end cutting and the like, combines the two procedures of a sub-rapid solidification technology and hot forming into a whole, and greatly shortens the production process flow of steel materials. The double-roller thin strip casting and rolling process has the advantages of saving energy consumption by more than 50%, saving equipment investment by about 70% and the like.
The molten steel cools on the mould surface very quickly and some oxides or other impurities may precipitate and adhere to the mould surface, which are difficult to remove in the cold state. These substances affect the uniformity of heat transfer on the mold surface and the smoothness of the mold surface, thereby causing surface defects in the strip. In the rotating process of the surface of the copper matrix of the crystallizer, due to repeated cold and heat impact, a layer of oxidation film is formed on the surface, and the oxidation film can greatly influence the heat transfer efficiency of the crystallizer, so that the temperature of the surface of the crystallizer is increased, and the strength and the heat transfer performance of the crystallizer are reduced due to secondary crystallization and other reasons.
In order to prevent the product quality defect caused by the above reasons, the surface of the crystallization roller needs to be cleaned. For example, chinese patent CN201110253468.8 discloses a method and a device for cleaning the surface of a twin-roll strip casting roll, wherein each casting roll of a twin-roll strip casting machine uses two brush rolls arranged up and down to clean the surface, at least one of the brush rolls has the same rotating direction as the casting roll, the linear velocity of the casting roll is constant and greater than the rotating speed of the casting roll, the roll surface cleaning device controls the distance or pressure between the brush roll and the casting roll by a hydraulic cylinder fixed on the bearing seat of the casting roll, and the flattening amount is controlled to be between 1-10 times of the average pit depth of the roughened casting roll surface, so as to ensure the efficiency of cleaning the roll surface; chinese patent CN201510641051.7 discloses a cleaning device and a cleaning method for the roll surface of a thin-strip continuous casting crystallizing roll, wherein the roll surface cleaning device comprises two brush rolls which are respectively arranged in parallel with the crystallizing roll and are arranged up and down on the non-molten pool side of each crystallizing roll; the brush roller is cylindrical, and slender metal wires are planted on the periphery of the brush roller to serve as bristles; bearing seats are arranged at two ends of the brush roller; the rear parts of the bearing seats are respectively provided with a pressure sensor; the two motors are respectively connected with the two brush rollers; the two hydraulic cylinders act on the bearing seat through the pressure sensor to drive the brush roller to be attached to or separated from the crystallization roller; a displacement sensor is arranged on the hydraulic cylinder; the cleaning method comprises the steps of gradually increasing the jacking force applied to the roller surface of the crystallizing roller by the brush roller according to a smaller gentle slope until a target value is reached, wherein the fluctuation of the casting force in the casting operation is not more than 5% of that before the roller surface cleaning device is put into the cleaning device; chinese patent application CN202010926640.0 discloses a roll surface cleaning device for strip casting, and a control method and a control device thereof, the roll surface cleaning device mainly comprises: the first brush roller and the second brush roller are positioned on one side of the driving crystallization roller; the third brush roller and the fourth brush roller are positioned on one side of the driven crystallization roller; first to eighth cylinders connected to the respective brush rolls; a pressure pneumatic proportional valve is arranged on a common rod cavity air inlet pipeline of each cylinder; the air inlet pipeline of each rodless cavity of each cylinder is respectively provided with a flow pneumatic proportional valve; the pressure pneumatic proportional valve and each flow pneumatic proportional valve are respectively connected with the PLC; chinese patent CN200610025066.1 discloses a method and a device for cleaning the roll surface of a continuous casting roll: in the initial casting stage, the brush roller device is pressed on the surface of the continuous casting roller, and the initial value given by the displacement sensor is x 0; if the system sends a deviation signal for changing the displacement to the sensor, the system drives the hydraulic cylinder to move to a new displacement value x which is x0+ delta x; the system scans the roll surface temperature of the continuous casting roll, compares a scanning curve with a set target curve, if the trend is consistent, the continuous casting roll is continuously cleaned under the condition of the pressing force of the existing brush roll device, if the trend is abnormal, the system verifies whether the cooling water temperature of the continuous casting roll is also abnormal, if the trend is abnormal, the controller calculates the displacement deviation amount required by the brush roll according to a formula and sends the displacement deviation amount to a displacement sensor, the displacement sensor drives a hydraulic cylinder to act, a control program is continuously circulated, if the trend is not abnormal, the data of the roll surface temperature scanning curve needs to be filtered, the controller calculates the displacement variation amount of the hydraulic cylinder required by the cleaning device according to the filtered data, and then drives the hydraulic cylinder to perform corresponding action. However, the existing devices and methods have the following disadvantages: (1) the defect that a deeper groove is formed on the surface of the crystallization roller in the steel brush cleaning process affects the cooling efficiency of the crystallization roller; (2) the cleaning efficiency is low; (3) the uniformity of the surface treatment of the crystallization roller was insufficient.
