Automatic casting blank flame cutting control system

Abstract

The invention discloses an automatic casting blank flame cutting control system. The automatic casting blank flame cutting control system comprises a controller, a fuel gas supply unit, an oxygen supply unit, a pulse generator, a power source, a fixed-length measuring system, a flame cutting device, a first motor, a second motor, a fuel gas electromagnetic valve, an oxygen electromagnetic valve, a blank-clamping electromagnetic valve, a pulse igniter and a flame detector, wherein the pulse generator transmits pulse signals to the controller so that the actual cutting thicknesses of casting blanks can be calculated conveniently; the power source is connected with the controller; the fixed-length measuring system is connected with the controller and transmits fixed-length signals to the controller; the flame cutting device cuts the casting blanks; the first motor and the second motor are respectively driven by a cutting cart frequency converter and a cutting gun frequency converter and drive the flame cutting device to work; and the fuel gas electromagnetic valve, the oxygen electromagnetic valve, the blank-clamping electromagnetic valve and the pulse igniter are respectively connected with the controller. A non-contact type image fixed-length detecting system and an automatic igniting device are adopted, shortcomings that the existing measuring system has lots of errors and faults, and is not easy to maintain and the like are overcome, the yield of the casting blanks is increased, and the energy is saved.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic control system for casting slab flame cutting. Background technique [0002] In the production process of the continuous casting machine, the flame cutting machine cuts the steel billet into a certain length to meet the steel rolling requirements of the rolling mill. Since the flame cutting machine runs continuously at high temperature for a long time, it is required to have extremely high reliability and good maintainability. In the current continuous casting flame cut-to-length cutting system, the positions where the cutting machine and the billet work synchronously, the cutting oxygen, the opening and closing of the energy medium, etc., generally rely on the accuracy of the signals sent by the travel switch, the proximity switch and other detection components. Normal operation, but the continuous casting machine billet cutting site environment is harsh, high tempera...

Problems solved by technology

In the current continuous casting flame cut-to-length cutting system, the positions where the cutting machine and the billet work synchronously, the cutting oxygen, the opening and closing of the energy medium, etc., generally rely on the accuracy of the signals sent by the travel switch, the proximity switch and other detection components. Normal operation, but the continuous casting machine billet cutting site environment is harsh, high temperature, water spray, dust, impact and other phenomena will affect the life of the detection element, which is often the cause of damage to the detection element and line

At the same time, the existing slab flame cutting system has disadvantages such as low degree of automation, complex installation of slab length measurement system, difficult adjustment, and large positioning error.
