Description

technical field

[0001] The invention relates to an alloy steel smelting process and the technical field of application thereof. Background technique

[0002] The existing bearing processing material is sulfur-free alloy steel, otherwise it will easily cause wear and tear between the installed equipment, the noise will be loud, and the service life will be short. During use, not only regular refueling and maintenance are required, but also the machine must be stopped to replace the bearing, which will increase the production cost. increase, affecting normal production. Simultaneously, because the oil filling hole is set, the pollution of the bearing is also caused. Contents of the invention

[0003] The purpose of the invention is to produce a high-temperature self-lubricating alloy steel that can improve the product's long service life and avoid oiling.

[0004] For every 100 grams of alloy steel in the present invention, the components are as follows: C: 0.7-1.5 grams, ...
