摘要

A screen bar for a bar screen may comprise a steel composite sheet having at least three steel layers: a top layer, a core layer, and a bottom layer. The top, core, and bottom steel layers may be interconnected by roll cladding in a non-releasable manner. In some examples, the core steel layer may have a higher deformability than the top steel layer and the bottom steel layer. Likewise, the top steel layer and the bottom steel layer may have higher hardnesses than the core steel layer. Such screen bars have extended service life and can be manufactured more cost effectively, amongst other benefits. Methods for manufacturing such screen bars may involve a variety of steps including hot rolling and/or heat-treating.
