Total or partial rebuilds, end to end.

When a furnace reaches the end of its campaign, IRF handles reconstruction of any type of furnace or its parts — from drainage and demolition to refractory assembly, steel supply and on-site rebuild.

Glass furnace cold repair and rebuilding
Total & partial reconstructions

One team for your whole rebuild.

At the end of the campaign, IRF rebuilds your furnace, in whole or in part, from draining to heat-up: demolition, refractory installation, steel supply and reconstruction on site.

One partner for the whole project means controlled lead times, consistent quality and clear responsibilities.

Our cold repair work

Four examples of what we do.

01

Cast in Place

Formwork, mixing, casting in place: we handle every step, with equipment sized for each job, from the glass-contact zone to the superstructure.

02

Feeder Rebuilt

Complete rebuild of feeders, to restore precise thermal conditioning and a steady flow of glass to the forming machines.

03

Furnace Building

Total or partial construction of the furnace: new refractories, steel structure and complete assembly on site.

04

Demolition

Complete demolition of the furnace, safely and by the book, with sorting and recycling of materials, to prepare the rebuild.

Project flow

From draining to heat-up.

1

Drainage

Controlled draining of the tank to prepare for demolition.

2

Demolition

Complete, safe removal of worn refractory and structure.

3

Rebuild

New refractories installed, monolithics placed, steel structure replaced.

4

Heat-up

Controlled heat-up to bring the furnace back into production, then joint sealing to make it tight.
