Abstract

The invention relates to a multifunctional vacuum-positive pressure smelting and solidification device, in particular to a device for preparing various special materials by smelting and solidification processes under hermetic vacuum and high pressure. The device consists of a smelting furnace and a unidirectional solidification furnace which are placed at a mutual angle between 90 and 100 DEG, and communicated through a sprue cup; the open end of the sprue cup is lower than a crucible in the smelting furnace and encloses the lower edge of the crucible, while the other end is lower than the upper edge of a unidirectional solidification die in the unidirectional solidification furnace; and fused mass casting speed is controlled by the tilting speed of the device, and the unidirectional solidification speed of fused mass can be controlled by the water velocity in a water cooled crystallizer and medium between the water cooled crystallizer and a casting die. The device can be used for producing porous foam materials, high nitrogen austenite stainless steel and metal / ceramic composite materials in the fields such as aviation, electronic, medicine and biochemistry, metallurgical machinery, petrochemical industry, energy and environmental protection, national defense and war industry and the like.

Description

technical field

[0001] The invention relates to multi-functional vacuum-positive pressure melting and solidification equipment, in particular to a kind of equipment for preparing various special materials by adopting melting and solidification processes in a closed vacuum and high-pressure atmosphere. The equipment can be used to prepare high-nitrogen austenitic stainless steel, high-porosity isotropic foaming material, high-strength directional porous material and metal / ceramic composite material. Background technique

[0002] High-nitrogen austenitic stainless steel is a new type of engineering material that has emerged with the advancement of metallurgical technology in recent years. In a broad sense, high-nitrogen austenitic stainless steel refers to the steel whose actual nitrogen content in the material exceeds the limit value that can be achieved by preparing the material under normal pressure (0.1MPa). High-nitrogen austenitic stainless steel has good mechanical pro...
