Casting blank cutting control device, cutting system and cutting method based on programmable logic controller (PLC)

Abstract

The invention provides a casting blank cutting control device, cutting system and cutting method based on a programmable logic controller (PLC). The control device comprises a conversion switch used for receiving clamping signals, a first switch, a second switch, a third switch, a fourth switch, a plurality of terminals, a high voltage igniter, an ignition electrode terminal and a plurality of delayers. The first switch, the second switch, the third switch and the fourth switch are connected with the plurality of terminals and are electrically connected with the plurality of delayers and the high voltage igniter through the plurality of terminals. The plurality of terminals are respectively and electrically connected with the plurality of delayers and the high voltage igniter and used for providing electric shock safety protection. The high voltage igniter is used for generating high voltage pulse voltage, the high voltage pulse voltage breaks down the air through an anode of an ignition electrode to reach a cathode of the ignition electrode to generate electric spark. The plurality of delayers are used for controlling connection working time length of electromagnetic valves. The continuous casting steel blank intelligent cutting device can save fuel gas and oxygen consumed by constant working of an auxiliary gun, reduces cost and reduces pollution.

Description

technical field [0001] The invention relates to a billet cutting control device and a billet cutting method, in particular to a billet intelligent cutting control device and a billet cutting method based on a programmable logic controller (PLC). Background technique [0002] In the process of producing various steel products in steel plants, there are two methods of using molten steel to solidify and form: the traditional die casting method and the continuous steel casting method. The continuous casting technology that appeared in European and American countries in the 1950s is an advanced technology that directly pours molten steel into shape. Compared with traditional methods, continuous casting technology has significant advantages such as greatly improving metal yield and billet quality, and saving energy. For the production of billets of different shapes, the cutting machines used are also different. Large-scale flying shears are often used for continuous casting of t...

Problems solved by technology

[0003] The traditional flame cutting machine is in a state where the cutting flame is always burning (always open flame) after cutting the slab and before cutting again. The torch is always burning while waiting for the slab to walk, which will waste a lot of gas and oxygen, which not only increases the cost, but also It will increase the emission of exhaust gas and cause environmental pollution
