Embodiment Construction

[0024] The embodiment of the present application provides an operation method for automatic hot-rolling steel extraction, which solves or partially solves the uneven tapping gap caused by the first-level steel extraction method in the prior art, and the large difference in operating time between teams and personnel, which increases the Operators are burdened by the technical problems that are likely to cause accidents. During the tapping process of the heating furnace, the tapping mode of automatic steel and manual steel can be switched; manual steel is tapped through manual control of each heating furnace; automatic steel is tapped The steel is tapped by controlling each heating furnace through the PLC control unit; the time required for the steel to be solidified at the first level is realized, the uneven tapping gap and the large difference in operating time are avoided, and the technical effect of reducing the burden on the operator is achieved.

Abstract

The invention relates to an operating method of automatically feeding steel for hot rolling. The operating method comprises the following steps of: in a tapping process of heating furnaces, adopting a tapping mode switchable between automatic steel feeding and manual steel feeding; manually controlling the heating furnaces to tap for manual steel feeding; and controlling the heating furnaces to tap by a PLC control unit for automatic steel feeding. The step of automatic steel feeding specifically comprises the steps: the PLC control unit is connected to communication units of four heating furnaces and sends a steel feeding signal to the communication units, and the communication units control corresponding heating furnaces to tap, wherein the four heating furnaces tap circularly; and the distances between slabs sent out by the heating furnaces are equal. According to the operating method of automatically feeding steel for hot rolling provided by the invention, the primary steel feeding time is cured, non-uniform tapping gaps and great differences in operating times are avoided, and the burden of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to an operation method for automatic steel extraction in hot rolling. Background technique [0002] On the 2250mm production line of the steel factory, the domestic advanced walking beam heating furnace is generally used. The system sends a signal of "allowing tapping" to the heating furnace. After receiving the signal, the heating furnace area checks the slab number and taps the steel. The method of manually obtaining steel will cause uneven tapping gaps, large differences in operating time between teams and personnel, increase the burden on operators, and easily cause many problems such as accidents. Contents of the invention [0003] The invention provides an operation method for hot rolling automatic steel extraction, which solves or partially solves the uneven tapping gap caused by the first-level steel extraction method in the prior art, and the large difference in oper...
