Abstract
The invention discloses a billet rolling control method for a CCS rolling mill, and belongs to the technical field of rolling control. The control method specifically comprises the following steps: the tail part of the current billet being rolled passes through a first material level to forcibly enter the bite rolling of the next billet, wherein the first material level is closer to the next billet relative to the safe material level of the system. Compared with the scheme in the prior art, the billet rolling control method for the CCS rolling mill has the advantages that the material tracking program is optimized, the rolling rhythm is improved, the yield is effectively improved, and the effective rate is 100%.
Description
Technical Field
The invention particularly relates to a billet rolling control method for a CCS rolling mill, and belongs to the technical field of rolling mill control.
Background
In the current billet rolling process, a CCS rolling mill 13# material (safe material level) is installed at a position 72.5 meters away from the center line of an E rolling mill at the back, and a steel feeding program is designed in an automatic rolling program: after the last pass of the CCS is finished, the tail of the billet leaves the No. 13 material, so that the next billet can be allowed to be rolled, and the purpose of this is to prevent the head of the next steel from colliding with the tail of the previous steel. Due to the fact that the production rhythm is fast at present, if the steel billet is waited to leave the 13# material, the biting of the next steel is carried out. The rolling speed is seriously affected.
Disclosure of Invention
Therefore, the invention aims to provide a billet rolling control method for a CCS rolling mill, which improves the rolling rhythm and the productivity.
Specifically, the method for controlling the rolling of the billet of the CCS rolling mill provided by the invention specifically comprises the following steps:
the tail part of the current billet being rolled passes through a first material level to forcibly enter the bite rolling of the next billet, wherein the first material level is closer to the next billet relative to the safe material level of the system.
Further, the safety material level is located on the CCS rolling mill at a position 72.5 meters away from the center line of the E rolling mill (edger), and the first material level is located on the CCS rolling mill at a position 47.5 meters away from the center line of the E rolling mill.
Further, the method for forcibly entering the biting rolling of the next billet is to press a driving button on a system operating platform to forcibly enter the biting rolling of the next billet.
The invention has the beneficial effects that: compared with the scheme in the prior art, the billet rolling control method for the CCS rolling mill has the advantages that the material tracking program is optimized, the rolling rhythm is improved, the yield is effectively improved, and the effective rate is 100%.
Drawings
FIG. 1 is a process schematic diagram of the billet rolling control method of the CCS rolling mill.
Detailed Description
The following description of the embodiments of the present invention is provided with reference to the accompanying drawings:
as shown in FIG. 1, in order to increase the production speed, the billet rolling control method of the CCS rolling mill of the invention presses a button 'DRIVE START' on a CP5 operating platform to force the next steel to be bitten after the previous steel position can be rolled when entering the first pass of the CCS each time. Through PDA data collection and analysis and calculation and negotiation of steel rolling technicians, the position of the 13# material is moved 25 meters from the position of 72.5 meters to the north, and meanwhile, a material tracking optimization program is written.
According to the measurement, the steel feeding time of each steel is increased by 5 seconds, 25 steel rolling is carried out per hour, 150 seconds are saved, 1 steel billet can be rolled per hour, the capacity can be increased by 120 tons per day, the heavy rail rolling is carried out per year for 150 days, the profit of each steel is calculated according to 300 yuan, and the annual economic benefit is 300 × 150 × 120 ═ 540 ten thousand yuan
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
Claims (3)
