Abstract The influence of V 2 O 5 on the phosphorus partition between liquid crude steel and heterogenous basic oxygen furnace (BOF) slag with CaO/SiO = 4.2 was investigated at a temperature 1600 °C in middle frequency induction furnace. Thereby transfer from “steel to slag” as well “slag steel” studied over holding time 60 minutes. measured results were shown capacity compared experimental val...

This paper deals with high energy consuming induction holding furnace. The improved version of coil design along additional electrical interlocks and alarm, modified hydraulic controls, strengthening mechanical structures saving proposals at furnace fume extraction system ensures trouble free operation hence continuity production all the planned plant operational days. project involves in purch...

In this paper, the effect of MgO, BaO, Na 2 O and SrO addition to a pre-melted CaO-Al2O3 -Si 2 O synthetic slag on sulfur removal from plain carbon steel was studied under the same experimental conditions. The slags were pre-melted at 1400°C in an electric resistant furnace and desulfurization experiments were carried out in a high frequency induction furnace. The results showed that ...

This paper presents the results of measurements of liquid metal fluidity and linear shrinkage of nickel alloy IN-713C in vacuum induction melting furnace Balzers VSG-2. Because of limited volume of the furnace chamber special models for technological trials were designed and constructed to fit in the mould of dimensions 170x95x100mm. Two different designs of test models were proposed: horizonta...

In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...
