Definitions
- the invention relates to a method for pouring hollow bodies into cast iron components.
- the method according to the invention is based on hollow bodies which are initially in sheet metal be preformed. Before the hollow body is completely closed, there is air pumped out, so that a certain negative pressure forms. Only after pumping out the The hollow body is sealed air-tight.
- the vacuum can result in Do not build up a hollow body such a high pressure that the hollow body inflates and after the melt has cooled, contact with the walls of the hollow body is lost, or that the hollow body is even damaged by excess pressure would.
- the hollow body can be heated before closing, so that after the closure and cooling also negative pressure in the hollow body sets and set the aforementioned advantages when pouring into the molten metal.
- the method according to the invention is particularly advantageous in the case of exhaust manifolds from Internal combustion engines applicable.
- Exhaust manifolds provide good insulation. Through the Insulation improves the performance of an exhaust gas turbine and unwanted heat radiation greatly reduced from the exhaust manifold to the environment.
