There can be used many different lance sizes and combinations in order to reach all expansion joints from outside, even at difficult reachable areas like behind buckstays, between port necks or tank blocks.<\/p>\n

The stream of welding\u00a0powder enriched with oxygen comes into contact with the hot refractory surface causing the metallic components to oxidize in a highly exothermic reaction.<\/p>\n

The existing heat development (over 2000\u00b0C) melts the refractory material with our welding powder which enables to close resp. seal gas tight expansion joints. This reaction results in a long lasting combination between both materials.<\/p>\n<\/div>

Various materials are available for the repair depending on the location of the damaged area in the furnace (see web page \u201cwelding materials and compositions<\/a>\u201c).<\/p>\n<\/div><\/div><\/div>
