WBT Electron is an expert in heat treatment and annealing of metal workpieces. We relieve stress from the material or influence the mechanical properties. This is done at high temperature with the help of insulated caps and automatically controlled gas burners.
With stress-relief annealing, the stresses in your material are reduced. These stresses are caused by various processes such as welding, deformation or casting.
Normalising annealing is applied to improve the mechanical properties and machinability of your material.
To improve the homogeneity of the material, we apply solvent annealing.
Hydrogen-free annealing (tempering)
Hydrogen-free annealing or tempering reduces hydrogen embrittlement in your material.
Forced cooling with air
We can also apply forced and accelerated air cooling of your material by means of fans. WBT Electron offers possibilities to quench with air, water or fog. Thanks to a special set-up we can ensure that your workpiece is quenched in a controlled way using forced air cooling or fog quenching. We offer fog quenching when quick and controlled quenching of very large workpieces is required, as for example with solvent annealing of stainless steel 310. This proven method was developed by WBT Electron and has since been applied for many years to the satisfaction of our customers.
Drying, curing or sintering of fire-resistant materials
Drying, curing or sintering of fire-resistant materials means that the material is heated sometimes up to 1300 degrees in order to obtain the correct properties. Using our high-temperature furnace we are able to dry, cure or sinter large quantities of fire-resistant concrete or other fire-resistant materials. This annealing furnace can reach a temperature of 1,400°C. This process ensures that the right material structure is obtained and/or the product is treated under more favourable conditions than at commissioning. This prevents any undesired variations in composition, structure or dimensions.
