Protection method for roller surface at environment temperature of -35 DEG C to +30 DEG C

Abstract

The invention discloses a protection method for a roller surface at the environment temperature of -35 DEG C to +30 DEG C. The protection method has the following advantages that (1) the roller surface is coated with a layer of light white oil crude oil without any additive, and the situation that common alcohol and ester additives with the carbon number distributed between C12 and C16 are crystallized, separated out and bonded to the roller surface in a low-temperature environment (the temperature is lower than 20 DEG C) can be effectively avoided; and (2) the outer ring of a roller is coated with a layer of oxidation-resistant and corrosion-resistant R5231 anti-rust oil, atmospheric environment gas can be isolated, the situation that the gas directly corrodes the roller surface, and consequently rust spots are generated on the roller surface is prevented, and meanwhile the situation that the anti-rust oil makes direct contact with the roller surface, and consequently the roller surface is difficult to clean subsequently is avoided.

Description

technical field [0001] The invention belongs to the technical field of rolling mill roll surface treatment technology, and in particular relates to a method for protecting the roll surface in an ambient temperature of -35°C to +30°C Background technique [0002] The existing roll surface protection method is carried out at an ambient temperature above 20°C in the ambient temperature. Rolling oil esters and alcohols will not crystallize in this temperature range. Rolling oil taken from the rolling mill and coated on the roll surface can protect the roll surface normally. , but in the low-temperature atmospheric environment in the north, it is impossible to use this method to achieve the effect of not sticking to the roll surface and protecting the roll surface at the same time, so there is an urgent need on the market for a roller surface that is used in the ambient temperature of -35℃~+30℃ Protection method. Contents of the invention [0003] The purpose of the present in...
