Ceramic Welding Process

This ceramic welding process is applied for more than 20 years in coke plants all over the world in the most important steelmaking group such as arcelormittal jfe china steel etc.

Ceramic welding process.

Why are ceramic ferrules essential for stud welding. Nano tec ceramic weld powders. Fosbel initiated a research project to address ceramic welding repairs on older ovens that do not heat as well as designed. Ceramic welding coke ovens ceramic welding the process from left to right.

These figures relate to silica type s ceramic welding powder mechanism of ceramic welding magma layer 3180 3540of reaction zone 3540 3720of welding nozzle projected powder reacted material in the. Non oxide ceramics are more difficult to join by this process as they tend to react with the glazes releasing gas bubbles which weaken the bond. Special glazes are available to join some of the ceramic and metal combinations. The process works in ambient conditions and uses less than 50 watts of laser power making it more practical than current ceramic welding methods that require heating the parts in a furnace.

50 w of laser power making it more practical than current ceramic welding methods that. The ceramic weld process reconstructs the refractory back to its original state. The fosbel ceramic welding process for glass furnace hot repair was invented and first applied in the late 1960 s. Unfortunately ceramic welding is only suitable for the treatment of medium and big cracks or holes ceramic welding together with s bricks.

Fosbel has pioneered and perfected this innovative hot repair process that is used to repair the inside hot face of any furnace refractory at operating temperature in most cases with minimal disruption to production. A team of engineers at the university of california san diego ucsd. Usually this method is employed for joining ceramics to metals. In many cases the cooler end.

Damaged wall prior to repair welding in progress finished repair. The technology works in ambient conditions and uses. Using the fusion welding method to join ceramics by concentration heating or with a high energy density heat source cracking in the ceramic easily occurs. Ceramic ferrules also known as ceramic arc shields are small rings made from ceramic material.

It is necessary to reduce the temperature gradient in and around the fusion zone as much as possible and to carefully control the heating and cooling speed during the joining process. Gas tight welding repairs reduce energy loss and solve environmental issues.
