Description
Classic cast iron bar breaker apparatus demonstrating the forces of thermal expansion and contraction. A steel bar sits in a cast iron frame and is locked by a cast iron pin. A gas burner fitted into the cast base heats the bar until expansion breaks the pin with a loud report, then a new pin can be fitted while hot and broken again as the bar cools and contracts. Models are available for coal, natural gas, or LP gas.
Cast Iron Bar Breaker, LP Gas Burner Base, Expansion and Contraction Pin Break Demo
Classic cast iron bar breaker demonstrating expansion and contraction. A steel bar lies in a cast iron frame and a cast iron pin locks the bar in place. A gas burner is fitted into the cast base and heats the bar. As the bar expands, it tries to bend the cast iron rod until the cast iron pin breaks with a loud report. With the steel bar hot, another pin can be fitted and locked. As the bar cools and contracts, again the cast iron bar is broken with a loud report. This model is configured for LP gas operation.
