Preparation process of high-strength durable stainless steel slicing knife

Abstract

The preparation process of a high-strength and durable stainless steel slicing knife of the present invention uses molten stainless steel raw materials to be molded directly, which is quick and easy. Compared with the prior art, the prepared slicing knife not only has the properties of crystalline silica High hardness, but also has the excellent toughness of stainless steel, even if the thickness of the blade is ultra-thin, the hardness is very high, very light and sharp. Due to the silicon dioxide layer on the surface, the wear resistance is excellent, basically no need to sharpen the knife, and the silicon dioxide layer almost isolates the stainless steel material of the blade from contact with the outside world, further eliminating the possibility of rust.

Description

technical field [0001] The invention relates to a knife preparation process, in particular to a high-strength and durable stainless steel slicing knife preparation process. Background technique [0002] The slicing knife is a tool that people often use in daily life. People always hope that the thinner the slicing knife is, the sharper the better. However, due to the limitation of current materials, the slicing knife cannot really be made into a "slice" shape, no matter how thin the back of the knife is. The thickness is also greater than 3mm, otherwise it is very easy to deform and break, which also leads to the fact that the slicing knife cannot be sharp enough to cut iron like mud, and the weight is not reduced too much. It needs to be polished frequently during use or it will become blunt. Moreover, for the same material, the thickness of the knife is directly proportional to the hardness, and the thinner the knife, the lower the hardness, so it is impossible to realize ...

[0002] The slicing knife is a tool that people often use in daily life. People always hope that the thinner the slicing knife is, the sharper the better. However, due to the limitation of current materials, the slicing knife cannot really be made into a "slice" shape, no matter how thin the back of the knife is. The thickness is also greater than 3mm, otherwise it is very easy to deform and break, which also makes the slicing knife not sharp enough to cut iron like mud, and the weight is not reduced too much. It needs to be polished frequently during use or it will become blunt.

Moreover, for the same material, the thickness of the knife is directly proportional to the hardness, and the thinner the hardness, the lower the hardness, and it is impossible to realize a knife that is light, sharp and sufficiently hard.

Therefore, in real life, in order to meet the requirements of sharpness and hardness, it is often necessary to be equipped with various knives, such as slicing knives, chopping knives, and bone chopping knives, which is really troublesome.

[0003] In addition, the existing stainless steel knives do not rust under normal conditions, but they may also rust in a humid environment with a lot of electrolyte substances, and they cannot be completely rust-free
