Problems solved by technology

The outer ring of the bearing is an annular thin-walled ferrule, and the inside of the outer ring is a concave deep groove. After quenching, a large amount of quenching oil is taken out of the deep groove inside the outer ring. Because the mesh belt furnace heat treatment equipment is generally cleaned by cross spraying Therefore, when cleaning, the quenching oil in the outer ring channel is difficult to be cleaned, and there are often residues, which are adsorbed on the inner surface of the bearing after tempering, affecting the appearance quality of the bearing

Abstract

The invention discloses a cleaning agent special for bearing outer ring quenching oil and a preparation method of the cleaning agent and belongs to the technical field of cleaning agents. The cleaningagent disclosed by the invention comprises the following components in parts by mass: 9-15 parts of a surfactant, 4-6 parts of a wetting agent, 3-5 parts of a grease emulsifier, 2-3 parts of a corrosion inhibitor, 1-2 parts of an antifoaming agent and 25-35 parts of water. The cleaning agent can be compounded with a multi-effect enzyme cleaning fluid. The cleaning agent disclosed by the inventionhas an excellent cleaning effect on spontaneous black quenching oil after quenching of the bearing outer ring, particularly residual quenching oil in a bearing outer ring raceway. Moreover, the cleaning agent disclosed by the invention is specially researched and developed aiming at the quenching oil, the cleaning effect is excellent, any residue is not remained after cleaning, and the workpiecesurface is bright and blot-free after tempering.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and more specifically relates to a special cleaning agent for quenching oil for outer rings of bearings and a preparation method thereof. Background technique [0002] Surface heat treatment is a process that changes the mechanical properties of the surface by heating and cooling the surface of the steel part. Surface quenching is the main content of surface heat treatment, and its purpose is to obtain a high-hardness surface layer and favorable internal stress distribution to improve the wear resistance and fatigue resistance of the workpiece. All parts before machining and heat treatment must be cleaned to remove surface grease, dirt, cutting fluid and metal debris. The quenched parts must also be cleaned before entering the tempering furnace to remove the oil or inorganic salts attached to the surface. If the workpieces after oil quenching are not cleaned sufficiently, a large amount ...
