In ceramic welding processes oxidizing gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder.
Ceramic welding powder mixture.
Ceramic welding using s bricks as back panel.
In order to reduce any tendency for the weld mass to include a low grade.
The exothermic reaction at the point of impact melts the projected powder and the refractory surface creating a bond very similar to the effect of metallic welding.
Most varieties are not explosive but can create brief bursts of heat and high temperature in a small area.
Principle of ceramic welding.
Unfortunately ceramic welding is only suitable for the treatment of medium and big cracks or holes ceramic welding together with s bricks.
A mixture of ceramic and metallic particles are driven by oxygen flow and projected on to the hot refractory surface which requires the repair.
Many different lance designs and sizes are available which makes it possible to work on damaged areas in the furnace that are normally difficult to reach such as the crown port necks burner arches and.
Ceramic welding powder resco ceramic welding powders for use in coke oven repairs include.
Silica type s is suitable for the majority of ocoke oven repairs.
Fireclay type d is used for fire brick or chamotte applications.

Ceramic welding technology a mixture of ceramic and metallic particles is projected with oxygen onto a hot refractory substrate.
Hotface welding to carry out ceramic welding during furnace operation a dry mixture the welding material is pumped into the furnace.
The exothermic reaction at the point of impact melts the projected powder and the refractory surface creating a bond very similar to the effect of metallic welding.
In ceramic welding processes oxidising gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder becomes at least partially melted or softened and a cohesive refractory mass is progressively built up against that surface.
The exothermic reaction at the point of impact melts the projected powder and the refractory surface creating a ceramic bond.
A thermite mixture using iron iii oxide thermite ˈθɜːrmaɪt is a pyrotechnic composition of metal powder and metal oxide.
