Abstract:
1. A process container comprising: a metallic casing having outwardly projecting threaded bolts welded onto an outer side thereof; at least one refractory cladding layer disposed on an inner side of said casing; cooling elements disposed on and connected to said outer side of said casing, wherein each cooling element comprises a metallic base plate disposed on said outer side of said casing and at least one cooling channel connected to said base plate in a heat-conducting manner, wherein said metallic base plate is configured to change in dimension under thermal stress and conform to dimensional changes of said casing, wherein said base plate is connected to said outer side of said casing by being screw connected to said threaded bolts of said casing such that said base plate of said cooling element nestles against said casing by flexural deformation due to clamping pressure of the screw connections; and means for connecting ends of one of said cooling channels to ends of an adjacent one of said cooling channels, wherein said threaded bolts are distributed over an entire surface of a respective cooling element and not only along edges of the cooling element, wherein said threaded bolts extend through bolt holes provided in said base plate, and wherein said threaded bolts extend along edges of said base plate.
