SIMETAL OFSM - General information

SIMETAL OFSM is an optical foaming slag detectionand control system for automated carbon injection atall kind of electric arc furnaces. Main purpose isexact detection of slag height inside the EAF vesselcombined with advanced control algorithms for most

efficient use of injection material.

System benefits :

Increased productivity Low refractory consumption Low injection carbon consumption

Arguments for our system are

High sophisticated technology Enhanced operation comfort Measurable savings Experiences

SIMETAL OFSM System Setup

A cooled and protected industrial camera plus machine vision is detecting the

height of slag inside of the furnace vessel. During line-of-sight obstructions the

slag flow out of the slag door is evaluated and gives reliable measurings of the

slag height.

Regulation output can be interfaced with any common type of carbon injectionmachines.
