Problems solved by technology

Or at least one of Fe-based alloys, Co-based alloys and Ni-based alloys is selected from the powder mixture of matrix metal mixed with VC powder with a particle size of less than 10um. This material has good corrosion resistance and wear resistance. But it contains VC powder with high price, and the preparation process is complicated
[0010] Through the comparison and analysis of the above patents, it can be seen that the stainless steel in the prior art cannot fully meet the current use and manufacturing requirements. The main problem is that the cost of the stainless steel is high due to the high wear resistance, and the low-cost stainless steel has generally poor wear resistance. Therefore, it is necessary to develop a stainless steel material with high wear resistance and low cost

Description

technical field [0001] The invention relates to the technical field of oil presses, in particular to a press chamber of a household oil press and preparation materials thereof. Background technique [0002] Household oil presses are generally based on screw presses. The principle is that there is a press chamber outside the press rod, and the drive mechanism drives the press rod to rotate in the press chamber, and the oil (such as peanuts, melon seeds, etc.) On the one hand, the space between the rod and the press chamber is squeezed by the press rod, and on the other hand, the oil materials are squeezed each other, so that the oil in the oil is squeezed out and flows away along the press chamber, and the remaining oil residue continues to flow in the press rod. Driven to send out from the end of the squeeze rod. [0003] The oil leakage opening of the pressing chamber also has a great influence on the oil extraction efficiency. Most of the oil leakage openings in the prior...
