Problems solved by technology
Afterwards, for the slab check before 9 o'clock, the server will determine the last furnace loading time as 9 o'clock, so that the furnaces cannot be allocated to the slabs according to the principle of cross-charging, resulting in the slabs being loaded into the wrong furnaces. It will lead to serious quality accidents such as mixed steel
[0012] In addition, when multiple terminals are used to alternately check slabs, if the time of each terminal is inconsistent, it may also cause single-furnace check and mixed steel problems
[0013] In addition, when the time between the terminal and the server is inconsistent, it will affect the control of the process control level mathematical model on the temperature and speed of the rolled piece, affecting the accuracy of the model and product quality

Embodiment Construction
[0033] Various example embodiments will now be described more fully with reference to the accompanying drawings.
[0034] figure 2 A flow chart showing the heating process control flow in the hot continuous rolling process control according to the embodiment of the present invention.
[0035] In step S201, before the terminal logs into the server to control the heating process, the system time sysT of the server is obtained.
[0036] For example, when the data storage system of the server is an ORACLE database, the system time sysT of the server may be acquired through an SQL statement.
[0037] In step S202, the terminal resets its own system time based on the acquired system time sysT of the server. Since the system time of each terminal is set based on the system time of the server, the time synchronization of each terminal is realized.
[0038] In step S203, the terminal locks its own system time so that it cannot be modified.
[0039] For example, when the terminal u...

The invention provides a heating process controlling method during controlling a hot tandem rolling process, which comprises the following steps of: (a) obtaining a server system time before a terminal logs in the sever to control the heating process; (b) resetting the terminal system time based on the obtained server system time by a terminal; (c) locking the terminal system time by the terminal, thereby not being capable of changing the terminal system time; (d) checking a blank board to be heated to define the furnace number of the blank board to be heated; and (e) putting the blank board to be heated into the furnace which corresponds to the defined furnace number.
Description
technical field [0001] The present invention relates to hot continuous rolling process control, more specifically, relates to a heating process control method in hot continuous rolling process control. Background technique [0002] The hot rolling process control system is the core of steel rolling control. It integrates electronic equipment, instruments, computers and other information technologies to realize detection, control, optimization, scheduling, management and decision-making for the hot rolling production process, so as to increase production, Improve quality, reduce consumption, and ensure safety. The hot rolling mill adopts process control level, its control mode is server-terminal mode, the server completes the relevant calculation and control processing, and the terminal is used for operation display, guidance and operator instruction input, another important function of the terminal is the time It shows that the operator completes relevant operation records ...
