Definition: Furnace with removable muffle for working under protective gas: a scoop is a mobile muffle in refractory steel provided with an inert gas inlet. The muffle is designed to be placed in a chamber furnace with the parts themselves arranged in the muffle. It is then possible to work under protective gas.
Construction: The muffle is parallelepiped-shaped (with one hinged face closing by gravity), with a gas inlet (which also serves as a handle) and a mobile floor grid system on which the parts are placed. The mobile floor makes it easy to transfer the parts from the muffle to the quenching tank.
Heating: The maximum temperature withstood by the muffles is 1100 °C. Our muffles are available with our chamber furnaces for 1100 °C, or 1200 °C for more intensive use.
Our packs are composed of a furnace able to receive a muffle, a ladle and protection for the heating elements to avoid any damaging contact between them and the muffle.
Type of gas: Working with non-flammable gas (nitrogen, forming gas 95-5 etc.).
Pneumatics: Our ladles are fitted with a valve to regulate the air supply. Type 24° pipe unions (according to ISO 8434-1) M16x1,5.
Options available upon request: Small quenching tanks: sheet 471,472, Aluminised protective gloves, Connecting tube, 3 metres: N15178, Rapid air cooler for ladle: sheet 699, Axron Swiss Temperature Programmer.
