Frequently asked questions
What happens if refractory is heated up too quickly?
Areas next to each other expand at different rates and the stresses crack the lining; residual moisture can turn to steam too fast and cause an explosion. Moisture can also be driven deeper into the refractory and trapped there, even when the hot face looks dry – shortening the campaign life and causing premature refractory failure.
Is the dry-out only for new plants?
No – it is offered for complete units and greenfield plants as well as for partial repairs after maintenance, to improve campaign life, prevent premature refractory failure and avoid steam explosions and cracking. The service is available 365 days a year.
How long does a glass furnace heat-up take?
Typically about one month (28–30 days) for a float furnace and 18–20 days for a container glass furnace, in both cases including the filling with cullet.
Does Hotwork also do post-weld heat treatment (PWHT)?
Yes – on site or in Hotwork's own furnaces, for vessels, pressure tanks, towers, pipes and structures in construction, offshore, petrochemical plants and refineries. The procedure includes software-based thermal calculations (and Zick analysis for horizontal vessels), follows the current welding codes, and is followed by non-destructive tests such as ultrasound, magnetic particle, radiographic and hardness testing.
Is the service available at short notice?
Yes – Hotwork's heat-up service is available 24/7, 365 days a year, from every branch.
