Problems solved by technology

[0002] The structure of the existing household oil press is responsible for the pressing device. It is difficult to disassemble during the process of cleaning the oil press, and because the particle size of the oil press raw materials used in the home is different, such as sesame, soybeans, peanuts, etc., if the oil press is used for For squeezing raw materials with smaller particle size (such as sesame), the grooves on the feeding rod of the oil press are designed to be smaller. The groove on the feeding rod of the oil machine must be designed to be larger, and the slag device in the prior art will block the oil outlet with oil slag, and it is necessary to remove the slag after stopping the machine. The operation is more troublesome and the slag removal effect is poor. ,low efficiency
[0003] Moreover, the slag breaking device in the prior art is relatively special due to the special use environment, which is easily interrupted and damaged by the machine during the slag breaking process, and has a short service life. Therefore, the slag breaking device needs to be made of high-strength stainless steel. Research is also increasing
[0004] The Chinese invention patent with the application number 200610147771.9 discloses a strong and tough ultra-high-strength stainless steel. The stainless steel adopts an optimized composition design, and adopts an enhanced double-vacuum smelting process and a large forging ratio forging forming technology. However, C, Co Lower content and therefore slightly less strength
[0005] The Chinese invention patent with the application number of 200610046063.6 discloses a high-strength, corrosion-resistant and high-temperature-resistant nano-alloy steel material and its production method. By adding Nb to molten steel, W, Mo, V and other elements are added to make the alloy steel 80 % grain size is less than 50 nanometers, the material composition used in this invention can meet the demand of high strength, but the production method of this invention is only through simple smelting to obtain high-strength corrosion-resistant and high-temperature resistant nano-alloy steel material, the obtained material strength is not high , and poor toughness
[0006] Most of the high-strength stainless steel materials in the prior art are only improved from one aspect, that is, from the material composition or the preparation method. Since the preparation method of the stainless steel material has a great influence on the comprehensive performance of the stainless steel material like its chemical composition, there is It is necessary to develop a high-strength stainless steel material that meets the high-strength requirements in terms of material composition and can exert the best performance of the material in terms of preparation methods to obtain a high-strength stainless steel material with excellent comprehensive properties
