Abstract
The invention discloses thermal-treatment-free copper-contained alloy antibacterial stainless steel. When prepared through smelting by using a medium-frequency induction furnace, the thermal-treatment-free copper-contained alloy antibacterial stainless steel is prepared through the following steps of firstly, adding low-carbon steel, and melting; then, adding ferrotitanium, a nickel sheet, ferrochrome, ferrosilicon, ferromanganese and a covering agent, heating to 1650+ / -5 DEG C until furnace charges are completely melted, then, cooling to 1550-1600 DEG C, adding electrolytic copper, standing for several minutes, and next, pressing mixed rare earth into a metal melt by using a pressing ladle to stir; adding an electrolytic aluminum sheet, deoxidizing, slagging off, pouring and forming. By using the technology disclosed by the invention, the obtained stainless steel can have an antibacterial property in a casting state without thermal treatment, so that the energy consumption and production cost are greatly reduced.
Description
technical field [0001] The invention belongs to the field of preparation methods of copper-containing alloy antibacterial stainless steel without heat treatment. Background technique [0002] With the development of the economy and the improvement of people's living standards, people pay more and more attention to the surrounding environment and their own health. Materials put forward higher requirements, and the voice of green processing and green production is becoming stronger and stronger. Antibacterial stainless steel is a new type of material that emerged under such a situation. Antibacterial stainless steel is a new type of material developed by the intersection of material science and environmental science. It is characterized in that the material itself has antibacterial and sterilizing properties, and can be used in food processing, sugar production, pharmaceutical production, tableware and cooking utensils, bathroom equipment, medical equipment As well as variou...
