Billet flow counting method and equipment for continuous casting machine

Abstract

The invention relates to a billet flow counting method and billet flow counting equipment for a continuous casting machine, and belongs to the technical field of continuous casting production and measurement in the metallurgy industry. The invention adopts the technical scheme that: a steel moving vehicle pushes billets to a rotary trolley from a step cooling bed of the continuous casting machine through the control process of a programmable logic controller (PLC), and the rotary trolley rotates to a terminal position and is connected with a billet transport roller way for rolled steel to realize heat transport of the billets; a limit switch is arranged on one side of a rotary terminal position of the rotary trolley and connected with the PLC through a cable; and when the billet approaches the switch and then a signal is generated, the number is automatically added into the counting amount, finally the number of the billets is obtained, and the counting operation is completed. Because double limit switches are adopted for matched counting, the reliability of metering control is improved, and the operation is stable; because an infrared camera is canceled, the cost is reduced, and maintenance of personnel and consumption of equipment spare parts are reduced; and meanwhile, the equipment can accurately count.

Description

Technical field: [0001] The invention relates to a continuous casting machine billet flow counting method and equipment, and belongs to the technical field of continuous casting production measurement in the metallurgical industry. Background technique [0002] At present, the infrared counting system is generally used for counting and settlement in the hot delivery of continuous casting slabs from steel mills to rolling mills. The system consists of an infrared camera, a camera drive platform, a dedicated computer for the counting system, and a set of counting system design software. Its basic working principle is: the steel billet is pushed onto the rotary trolley by the stepping cooling bed of the continuous casting machine (the rotary trolley can hold up to 4 billets), and the rotary trolley rotates to the terminal position and the steel billet transport roller for rolling The road is connected to realize the hot delivery of the steel billet. At the terminal position o...

AI Technical Summary

Problems solved by technology

The system has high requirements on the working environment. If there is an external light source, vibration, or high temperature, the counting system will run out of order, and there will be under-counting and missing-counting phenomena.

In this way, the actual quantity needs to be adjusted manually, which not only increases the workload of the post workers, but also inevitably produces large errors.

In addition, because the computer software system does not have the function of shutting down and saving the value, once the computer fails, the quantity counted by a shift will not exist, which will make the calculation of the tapping quantity confusing and increase the difficulty of production settlement
