Irisa level-two ladle furnace system (LFS IRISA)

Ladle furnace is the main secondary metallurgical unit located between the arc furnace and the casting furnace. The main purpose of the ladle furnace unit is to keep the melt warm, improve its temperature, and also modify the chemical composition of the melt by adding ferroalloy to the it. The purpose of this system is to monitor the melting status, send or receive information to/from level one, communicate with level three (production coordination system), provide user and melting management pages, prediction of the instantaneous temperature of the melt, forecast of instantaneous analysis of melt and slag, and ferroalloy charge suggestion to achieve the target analysis and the like.

Features

Product Features and Capabilities

The Irisa level two ladle furnace system consists of several subsystems, each subsystem of which follows a part of the system’s functions.

The melt monitoring subsystem is the ladle furnace system main core, whose common activities include:

Heat Tracking

Receiving data from level one (temperature information, the material charge from silos, electrical data, etc.)

Processing received level one information and recording information in level two system (data such as arc start and ending, time and material charge amounts, sampling, etc.)

Ladle furnace working phases recognition based on the melting conditions and level one data

Handling particular situations such as analysis alteration

Sending the melt’s data to the level three automation system on time

The functions of this subsystem are as follows:

Calculating melting point (estimated and instantaneous)

Calculating the amount of energy loss based on the ladle’s hot or coolness

Calculating the amount of energy loss based on the fireproof mode

Calculating the amount of energy loss based on the ladle lifecycle

Calculating the amount of energy loss due to Argon blast

The functions of this model are:

Calculating estimated and instantaneous analysis of molten elements

Calculating estimated and instantaneous analysis of slag components

Calculating the melt’s weight

Calculate the slag’s weight

The ferroalloy model in the ladle furnace is responsible for calculating and proposing the ferroalloy required to charge in the ladle furnace in order to achieve the intermediate analysis or the ladle furnace output (target analysis).

Advantages
