Abstract
The liquid-cooled grill plate has a carrier and drive design (15), having a separate cooling body (K) that can be placed into said carrier and drive design (15) and permeated by the liquid and having wear plates mounted onto said cooling body (K). The cooling body (K) is a welded design formed by square tube sections (20-26) and profiled sections (27), said design forming continuous elongated recesses (28-30) extending across the entire extension with the exception of the square tube sections (23-26) bridging said recesses (28-30). The carrier design is a ribbed configuration made of planar steel parts that are welded together and the drive unit (15) encloses a hydraulic cylinder-piston unit, which is accommodated in the inside of a square tube (18), said tube being guided displaceably in a tunnel-like breakthrough on said ribbed configuration. Between the wear plates and the cooling body (K) a highly heat-conductive soft silicone film (31) is clamped, which ensures good heat transfer. In this way, it is ensured that during operation the wear plates always remain in the non-critical temperature range in that they are cooled by the cooling body (K) disposed beneath, which heats up t…
