Problems solved by technology

Since switches are used in the high-temperature area to detect the pre-hot spots and cut-off points of billets of different sections or the limit positions of cutting guns, etc., the number of switches is large, the reliability is poor, and the maintenance is large. Automatic cutting is not easy to achieve.
During the manual cutting process, the operator needs to frequently operate and pull various buttons and switches on the console, which is labor-intensive; over a long period of time, it is easy to cause f

Example Embodiment

[0025] At present, continuous casting machines in steel mills are all cut manually, and the main problems are: 1. During the cutting process, the operator has to frequently flip various switches and buttons on the operating table, which makes the work tense and labor-intensive. 2. Preheating oxygen and natural gas are always on during manual cutting, which causes serious energy waste. 3. For example, the 1# and 5# continuous casting machines of Chongqing Iron and Steel Plant are 5-strand billet casting machines, and each strand requires a cutting operator. The working method is "four shifts and three operations", and each casting machine has 4 There are 5 people in each shift, a total of 40 people (replacement personnel are not counted), and the work efficiency is low; with the increase of output and the improvement of casting speed, manual cutting has obviously been unable to meet production needs. Due to the difference in pulling speed and billet length, each cutter has to c...

Abstract

An automatic cutting system with computer control for the steel billet cast by the conticaster of multi-cross section square billet includes such steps as waiting for sizing signal, receiving the signal, clamping the billet, turning on the clutch of cutting gun, feeding oxygen, preheating, feeding oxygen for cutting, running the motor of cutting gun, measuring the size of cross section, cutting, cutting-off the oxygen, making the motor of roller way to rotate forward, releasing clamp, turning off the clutch of cutting gun, returning back to original position, and turning off the motor of roller way.

Description

technical field [0001] The invention relates to a steel billet cutting method and system used by continuous casting machines in steelmaking plants of iron and steel metallurgical enterprises, in particular to an automatic billet cutting system for multi-section billets (rectangular billets, round billets) continuous casting machines. Background technique [0002] In the prior art, the cutting of multi-section billet (rectangular billet, round billet) continuous casting machine billet in the steelmaking plant of iron and steel metallurgical enterprises generally adopts manual cutting, that is, the cutting system is processed by the computer system after the manual input signal The output signal controls the work of cutting gun, holding clamp and so on. Since switches are used in the high-temperature area to detect the pre-hot spots and cut-off points of billets of different sections or the limit positions of cutting guns, etc., the number of switches is large, the reliability...
