Example Embodiment

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] see figure 1 and figure 2 , the furnace body 1 is a horizontal single-chamber (or double-chamber) front and rear double-door structure. , Outer layer 6mm), the hearth 2 is a square shape, which is composed of soft carbon felt and hard carbon felt composite heat shield, graphite heating element, and sealed graphite box for degreasing from outside to inside. The furnace doors at both ends (that is, both ends of the furnace) are equipped with furnace insulation doors. When the furnace door is closed, the inner insulation doors seal the furnace ends to prevent the heat from radiating in the furnace. The insulation door of the furnace is equipped with a dynamic sealing opening and closing device, which opens to form an air duct during rapid cooling. The heating element is connected to the outside through the water-cooled electrode, which ...

Abstract

The invention discloses a vacuum degreasing sintering hardening integrated furnace which comprises a furnace body (1) and a furnace chamber (2); wherein, a blower corresponding to the furnace chamber (2) is arranged on the furnace body (1); the outlet end of the blower is provided with a flow collector (5) and a wind guide cover (3) corresponding to the furnace chamber (2); the outlet end of the blower is also provided with a radiator (4). The invention can complete the processes of dewaxing, sintering and air hardening in a process step, simplifies the production process, improves the production efficiency, and has compact general structure, small occupied area and low energy consumption.

Description

technical field [0001] The invention relates to an integrated vacuum degreasing and sintering furnace, in particular to an integrated vacuum degreasing, sintering and quenching furnace. Background technique [0002] The integrated vacuum degreasing and sintering furnace is a horizontal vacuum heat treatment equipment with the functions of vacuum degreasing and vacuum sintering. This equipment cannot be directly quenched and heat treated after sintering. This equipment is not suitable for hard alloy products that require direct quenching and heat treatment after sintering, nor can it be used for vacuum quenching of tool steel, die steel, high alloy steel, stainless steel, copper alloy, etc. Vacuum brazing of nickel-based, copper-based, silver-based brazing and other products, not to mention vacuum heat treatment such as degassing, annealing, tempering, etc., can not be used for degreasing and sintering of stainless steel and ceramic powder products. The disadvantages of high...
