Stainless steel tank production standards as follows: First, a stainless steel tank, which tank the components have sufficient strength to withstand the pressure and temperature of the tank. Second, it must have a standard aspect ratio, in general, the ratio of height to diameter is generally about 1.7 to 4 times, and is proportional to the container body and oxygen utilization. Again, stainless steel tanks should have a certain amount of cooling area, used to control the fermentation process temperatures required for each phase. Then, the stainless steel tank in the design should be less dead set, so the purpose is to ensure a thorough cleaning to prevent the growth of bacteria. Finally, stainless steel tank equipment, it must be equipped with a stirrer with a tight seal and reduce leakage. On non-magnetic stainless steel welding electrode material properties of tungsten copper infiltration test material as the non-magnetic stainless steel welding electrode materials used in stainless steel construction on the electronics industry. In order to improve the performance and extend the life of the welding electrode electrode, adding an appropriate amount of tungsten in the welding electrode materials. Next, different amounts of electrode material properties and the results have been studied, the results show that: first add the appropriate amount of the tungsten carbide powder can be increased hardness of the material, the ability of anti-ablation, and thus prolong the electrode life; secondly alloy of copper content in stainless steel tanks with the same basic production, not adding the right amount of tungsten carbide powder effect on the conductivity of the material; and finally, after adding the right amount of tungsten carbide powder infiltration of copper wire has a certain role in strengthening . An experimental method, the raw material of tungsten powder grades for Fw-1, purity of more than 99.9%, the average particle size Fisher method 1.25um. Tungsten carbide powder carbon content of 6.1%, particle size 4.92um. Electrolytic copper purity: greater than 99%.
