A kind of operation method of hot rolling automatic steel

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...
