Problems solved by technology

There is a hot billet above the bearing seat for a long time, and the bearing works under high temperature (about 100°C) baking for a long time. The grease is easy to lose, and the bearing is damaged due to lack of oil. Higher, the actual working temperature in some bearing housings may exceed 150°C

Embodiment Construction

[0032] A kind of grease specially used for the front roller bearing of the furnace in the metallurgical industry. The weight percentage of each component of the raw material is:

[0033] Diphenylmethane-4,4’-diisocyanate MDI 3-8%

[0034] Octadecylamine 0.5-2%

[0035] Cyclohexylamine 1-5%

[0036] Base oil 1 40-50%

[0037] Base oil 2 30-45%

[0038] Antioxidant 0.4-0.6%

[0039] Anti-rust agent 0.4-0.6%

[0040] Extreme pressure anti-wear agent 2-6%

[0041] Adhesive 0.5-3%

[0042] Filling agent 1-8%

[0043] Wherein, the base oil 1 is a highly refined mineral oil with high viscosity; the base oil 2 is a base oil synthesized with esters; the antioxidant is phenyl-2-naphthylamine; The rust agent is sodium sebacate; the extreme pressure antiwear agent is T306 extreme pressure antiwear agent; the adhesive is polyisobutylene, and the filler is melamine

[0044] The preparation method of the grease specially used for the front roller bearing of the furnace in the metallurgical industry includes...

Abstract

The invention discloses lubricating grease special for a front furnace roller way bearing of metallurgy industry and a preparation method thereof. The lubricating grease comprises the following raw materials in percentage by weight: 3 to 8 percent of diphenylmethane-4,4'-diisocyanate MDI, 0.5 to 2 percent of octadecylamine, 1 to 5 percent of cyclohexane, 40 to 50 percent of base oil 1, 30 to 45 percent of base oil 2, 0.4 to 0.6 percent of antioxidant, 0.4 to 0.6 percent of anti-rusting agent, 2 to 6 percent of extreme pressure anti-wear additive, 0.5 to 3 percent of adhesive and 1 to 8 percent of filling agent. During preparation, the raw materials are added into an oil tank and a saponification kettle for stirring and mixing at different temperatures and in certain order.

Description

Technical field [0001] The invention relates to the field of lubricating grease, in particular to a kind of lubricating grease specially used for furnace front roller bearings in the metallurgical industry. Background technique [0002] The metallurgical industry has a long production process, more complicated equipment, and its special working conditions (high temperature, water, dust, and heavy load), which make its requirements for grease very strict. In addition to good high temperature and tightness, the most important characteristic required for the grease for roller bearings in front of the furnace should be its ability to resist impact loads. Generally, the performance of general-purpose grease is not up to the performance requirements of the grease required for the conveying roller table before the slab enters the heating furnace. The past conveying method is cold delivery. The roller bearing can meet the requirements by using extreme pressure lithium. Hot delivery, the...
