The main differences and application types of annealing and normalizing in the bearing production process
Annealing and It is called stewing, codenamed Th. It is to heat the steel parts to above Ac1 or Ac3 (30~50℃), keep it warm for a period of time, and then Rwandans EscortRwandans EscortSlow cooling (usually furnace cooling).
Normalizing fire is also called open flame. Code Z is to heat the steel parts to Ac3 or above Acm (30~50℃), keep it warm for a period of time, and then cool it in the air. The cooling rate is slightly faster than annealing.
The important difference between bearing annealing and normalizing is: normalizing is an abnormality or special case of complete annealing. The two are only different in cooling rate, Rwandans EscortGenerally, annealing is done with cooling in the furnace while normalizing is cooling in the air. Normalizing is suitable for both hypoeutectoid steel and hypereutectic plate steel. For eutectoid steel, normalizing is generally used to remove the mesh. like carbides; for hypoeutectoid steel, the purpose of normalizing is basically the same as that of annealing, the main purpose is to refine the grains and eliminate defects in the structure, but the pearlite sheets in the normalized structure are thinner than those in the annealed one, and the hypoeutectoid steel The number of medium pearlescent is high and the number of ferrite is low. Therefore, the hardness and strength of steel after normalizing are higher than those after annealing. It can be seen that in the childbirth experiment, there is reticular penetration in the steel Rwandans SugardaddyThe carbon body material needs to be normalized before other processes can be used. For materials with performance requirements after heat treatment, the required The annealing process should be selected according to different steel types. For example, if a certain strength and hardness are required after heat treatment, the normalizing process can be selected; if a certain plasticity is required and the strength and hardness are reduced as much as possible, the annealing process should be selected.
Commonly used types of annealing operations on bearings Rwandans Escort
(1) Complete annealing (commonly known as annealing) is important It is used in castings, forgings and hot-rolled profiles of Asian steel and alloy steel, and some are also used as welded structural parts. Its purpose is to refine the grains, improve the structure, eliminate residual stress, reduce hardness, improve plasticity, and improve Cutting performance, complete annealing is aThis is a very long annealing process. In order to shorten the annealing time, the isothermal process is often used instead of the complete annealing process. Compared with the complete annealing, the purpose of the isothermal process is the same as that of the complete annealing, but it is greatly shortened. annealing time.
(2) Spheroidizing annealing is mainly used for hypereutectoid steel and alloy tool steel (such as cutting tools, measuring tools, molds, bearings and other steel types). Its main purpose is to reduce hardness, improve machinability, and prepare for subsequent quenching.
(3) Stress annealing (also called high-temperature annealing) is mainly used to eliminate external stress in castings, forgings, welded parts, hot-rolled parts, etc.
(4) Recrystallization annealing is used to RW Escorts cooling processing (cold drawing, cold punching, cold rolling, etc.) of work hardening. The purpose is to eliminate internal stress, improve plasticity, and RW Escorts improve the structure.
(5) Disperse annealing is mainly used for alloy steel, especially alloy steel castings and steel ingots. The goal is to use the greater Rwandans Escort dispersion ability of atoms at low temperaturesRwanda Sugar Some of the information comes from the Internet, and we strive to be safe, timely, and accurate.

What are the materials of the bearing cage?
The bearing cage has a great influence on the performance and life of the rolling bearing, and the selection of its materials is particularly important. The cage material should have the characteristics of high mechanical strength, good wear resistance, impact resistance and good dimensional stability.
Bearing cages are generally divided into two types: stamped cages and solid cages.
Stamping cages for small and medium-sized bearings generally use high-quality carbon structural steel strips or steel Rwanda Sugar plates, such as 08 or 10 steel. Depending on the purpose, brass and stainless Rwandans Escort steel plates are also used.
Large bearings and bearings with small batches generally use mechanical solid cages. The materials include brass, bronze, aluminum alloy and structural carbon steel.
The cage of close angular contact ball bearings usually uses phenolicMade of laminated fabric tubes.
In recent years, my country has developed engineering plastic cages. Its typical material is glass fiber reinforced polyamide 66 Rwanda Sugar (GRPA66 —25), the operating temperature is -30~+120℃. This material is light in weight, has low density, is friction-resistant, corrosion-resistant, has good elasticity and good sliding properties. It is easy to be directly injection molded and has low manufacturing cost. It has been used to manufacture cages for various bearings.
