Low-odor stainless steel cold-rolled sheet rolling oil

Abstract

The invention discloses low-odor stainless steel cold-rolled sheet rolling oil which is prepared from, by weight, 90-95% of hydrofining mineral oil, 3-8% of polyol ester oily agents, 0.5-3% of extremepressure agents, 0.01-0.5% of anti-rust agents and 0.05-1% of antioxidants. The rolling oil meets the requirements of lubrication, friction reduction and board cleanliness in the rolling process, andovercomes the shortcoming that traditional rolling oil has a certain irritating odor, is harmful to environments and affects employees' health.

Description

Technical field [0001] The invention belongs to the field of oil products for metallurgical rolling mills, and relates to a stainless steel cold-rolled sheet rolling oil, in particular to a low-odor stainless steel cold-rolled sheet rolling oil. Background technique [0002] Stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is characterized by high strength, sharply hardening during cold deformation, but good plasticity. Stainless steel cold rolling is a processing method in which the rotating rolls give pressure to the strip under certain conditions to cause the strip to produce plastic deformation. The rolling process conditions of the stainless steel sheet are very demanding, and it requires a supporting rolling The oil should reduce the friction between the roll and the plate, reduce the wear of the roll, provide a stable friction interface, and improve the surface quality of the plate.

Problems solved by technology

The sulfur and phosphorus in the extreme pressure agent, as well as the long-chain fatty alcohols and fatty acids commonly used as oily agents, mostly have a relatively heavy pungent smell, which will produce a relatively strong pungent smell during long-term high-temperature cycle use, which not only pollutes the mill The on-site working environment will also cause certain harm to the human body.

[0004] Disclosed among CN106281592A is the use of containing inactive alkyl polysulfide, light-colored sulfurized fatty acid, ashless sulfur phosphorus anti-wear extreme pressure agent components, sulfur-containing, phosphorus-containing anti-wear extreme pressure agents will still produce pungent odor ,polluted environment

CN106566598A proposes to use oily agent containing lauryl alcohol and lauric acid and adopts dialkyl dithiophosphate as extreme pressure agent, still does not solve the pollution problem of pungent smell to environment

The rolling oils mentioned in the above patents all have certain application effects, but in the preparation process, sulfur-based and phosphorus-based extreme pressure agents are added, or fatty alcohol and fatty acid oily agents are added, or special component requirements are used. Additives or base oil components, so that the prepared rolling oil has more or less pungent odor, pollutes the on-site processing environment, affects the health of relevant personnel, difficulties in purchasing raw materials, and increases in the cost of rolling oil, etc.
