Hot rolling oil composition and application thereof

Abstract

The invention relates to a hot rolled oil composition and application thereof. The hot rolled oil composition is composed of the following components in parts by weight: a) 40-80 parts of base oil; b)1-50 parts of an oily agent; c) 0.1-15 parts of an extreme pressure agent; and d) 0.01-1 part of a demulsifying agent. The hot rolled oil composition provided by the invention can better meet lubrication requirement of a hot rolling technology and can be used for lubrication during hot rolling of stainless steel.

Description

technical field [0001] The invention relates to a hot rolling oil composition and its application. Background technique [0002] In the hot rolling process of stainless steel plate, the scale is much less than that of ordinary steel, so the roll and the strip are in direct contact, and thermal adhesion is easy to occur on the roll surface in the front section of rough rolling and finishing rolling, which aggravates the uneven wear of the roll and leads to product failure. surface defects. Due to the strict requirements on the surface finish of the stainless steel plate, good lubrication is very necessary to prevent thermal adhesion of the roller surface. In hot rolling conditions, work rolls in contact with the strip and cooling water produce Fe 3 o 4 and Fe 2 o 3 Oxide with high hardness, which sticks to the surface of the roll, makes the roll produce a dark surface, that is, black skin. Black skin is the main cause of abnormal roll wear. After using hot rolling lubr...
