Wirtz Model 40/40C Mechanically Operated Gravity Grid Casting Machines
The Wirtz Models 40/40C are high speed gravity grid casters designed with state of the art controls and technical enhancements. Casting efficiency is provided by electric mold heat, greatly improved temperature controls, and our non-recirculation lead delivery system (LDS). Electric Mold Heat is applied to both the moveable and stationary halves of the mold by cartridge heaters. Automatic temperature controllers monitor the temperature settings of the mold, ladle and feed line. Any fluctuation in these temperatures is automatically corrected. The lead delivery system (LDS) has been drastically improved because the LDS does not use a return lead trough. This system flows from the lead furnace to a dispensing valve where an adjustable amount of lead is allowed to enter the ladle after each pour. Dross is controlled with gas shielding, ladle covers, and drip bars.
