Abstract
The invention provides high pressure metal smelting and processing. Existing steel smelting and liquid metal processing are conducted under ordinary pressure. Density and properties of materials can be improved when metal materials are processed under high pressure, wherein the high pressure is higher than 1 MPa. A steel refining furnace and the liquid metal are placed in a high pressure vessel or a high pressure space, processing or solidifying is conducted under the high pressure, wherein the high pressure is higher than 1 MPa. Properties of produced metal materials are greatly higher than produced materials which are produced under normal atmospheric pressure. For example, in the low pressure casting of the aluminum alloy materials, if aluminum alloy materials are placed in the high pressure vessel to conduct low temperature casting, the produced products are equivalent to be cast in the high pressure. The produced products can not only have advantages of the low pressure casting but also have advantages of high pressure casting. The intensity and mechanical property of the produced products are higher than the low pressure casting. But the produced products do not have defects of the high pressure casting. The produced products do not have the problems of pores and the like which easily appear in the high pressure casting.
Description
Existing smelting iron and steel and liquid metal processing are all carried out under normal pressure.
And under the high pressure more than 1MPa, metal material is processed the density that can improve material and the properties of material.
The present invention is positioned over converter and liquid metal in high-pressure bottle or high-pressure space like this, processes under the high pressure more than 1MPa or solidifies, and the metal material performance of producing so all can be much higher than the material of producing under conventional atmospheric pressure.
Take the low pressure casting of aluminum alloy materials as example, if be positioned in high-pressure bottle, carry out low pressure casting, the product of producing so just is equivalent under high pressure cast, low pressure casting can be had advantages of, advantage in high-pressure casting is also arranged simultaneously, and density is higher than low pressure casting, and mechanical property is higher than low pressure casting; But, there is no the shortcoming of high-pressure casting, the problem that easily occurs in the high-pressure castings such as pore.
Claims (1)
1. processing and the curing to metallic solution is processed under the high pressure more than 1MPa.
