Converter steelmaking iron alloy smelting feeding weighing data collecting and monitoring system

Abstract

The invention discloses a converter steelmaking iron alloy smelting feeding weighing data collecting and monitoring system. The weighing data collecting and monitoring system comprises three weighting sensors which are arranged on the same horizontal plane on the outer portion of an iron alloy weighing hopper trolley and are arranged respectively through cylindrical pressing head mechanisms. The weighting sensors are connected with a secondary weighing instrument and a programmable logic controller in sequence, the programmable logic controller is connected with an industrial exchanger through the Ethernet, the industrial exchanger is respectively connected with a human-computer interaction interface and an ERP server, and the ERP server is connected with a plurality of clients. The converter steelmaking iron alloy smelting feeding weighing data collecting and monitoring system is accurate in data collecting, objective in recording, capable of conducting displaying in real time, capable of transmitting collected monitoring data into a production cost management system of a steel plant and capable of conducting data secondary development and utilization.

Description

technical field [0001] The invention belongs to the technical field of converter steelmaking production, and in particular relates to a weighing data acquisition and monitoring system for adding ferroalloy materials in the converter steelmaking process. Background technique [0002] In the traditional steelmaking production process, the weighing frame of the ferroalloy weighing bucket trolley is light, and the weighing frame has no positioning, and because the wire rope is used to tow the cable, the signal is interfered, resulting in large fluctuations in the number of the weighing table, and the accuracy of the original data collection cannot be guaranteed. . At the same time, since 14 silos and 3 converters share a set of ferroalloy scales, the alloy weighing is far away from the main control room of the converter production, and the data is not collected on the converter production operation interface, so the furnace manager cannot timely understand the ferroalloy require...

[0002] In the traditional steelmaking production process, the weighing frame of the ferroalloy weighing bucket trolley is light, and the weighing frame has no positioning, and because the wire rope is used to tow the cable, the signal is interfered, resulting in large fluctuations in the number of the weighing table, and the accuracy of the original data collection cannot be guaranteed.

At the same time, since 14 silos and 3 converters share a set of ferroalloy scales, the alloy weighing is far away from the main control room of the converter production, and the data is not collected on the converter production operation interface, so the furnace manager cannot timely understand the ferroalloy required by each converter The types of materials and the amount of each type of feed are prone to human error, resulting in substandard smelting components, which affects the quality of steelmaking and has serious consequences for smelting

Moreover, there is no statistical management of the alloy consumption of each converter and each furnace, and cost statistics and control cannot be carried out, which has a great impact on cost control.
