Problems solved by technology

[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
At the same time, due to the setting of the oil filling hole, the bearing is also polluted

Abstract

The invention relates the hyperthermia automatic lubrication alloyed steel and smelting method and application. The method comprises the following steps: putting scrap steel, castiron, chromium iron, ferro-molybdenum, ferrotungsten, ferro-vanadium, nickel, ferromanganese, ferrosilicium and ferrocolumbium into founding furnace, removing scum trough, deoxidizing, deoxidizing treatment, casting, heat treating, forming alloyed steel with sulfur, which can be used to make inner ring of axle bearing. The product has high heatproof property which is up to 600Deg.C, high intensity, hardness, tenacity and abradability. The product can be used at hostile environment, and there is no noise and non-pollution.

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, ...
