Description
Technical field
The invention belongs to metallurgical equipment lubrication technology, particularly high water resistant and drench continuous caster lubricating grease field.
Background technology
Continuous casting of iron and steel is compared with conventional iron and steel die casting process to have and the advantage such as produce to be simplified, recovery rate of iron is high, energy consumption is low, labor condition improves and continuous casting quality is good, so is one of technology with fastest developing speed in present steel industry.Continuous casting is that liquid molten steel is prepared to the process that follow-up rolling is become a useful person through being solidified into square (rectangle, abnormal shape, template) base.On continuous casting, hold steel-making, under connect steel rolling, be the critical process that steel industry is produced.The billet quality of producing by continuous casting installation for casting and quantity directly affect quality and the efficiency of next process steel rolling and finished steel.Yet continuous casting installation for casting will guarantee good operation, be unable to do without the lubricated, cooling of lubricating grease and sealing.
The main lubricant housings of continuous caster has: ladle turret and ladle trunnion (heavy duty, unbalance loading, impact, high temperature), mold oscillation platform globe bearing (high temperature and impact load), fan-shaped section nip rolls bearing (high temperature, heavy loading, water spray), withdrawal straightening machine pinch roll, bending roll, (150 ℃～200 ℃, supporting roll and dummy bar pinch roll bearing, secondary cooling water rinses bearing, bending roll bearing heavy loading), swinging shears bearing, (150 ℃～200 ℃, guiding knife rest slideway, depress roller and knife rest slideway have impact load) etc.The neck of each roller of continuous casting installation for casting is used the bearing that internal diameter is 60mm～150mm, and steel plate shaping carrying deflector roll bearing has 1500～2000, very high to the performance requriements of lubricating grease.The operation condition of continuous caster harshness is as follows to the performance requriements of lubricating grease: 1. continuous caster leaves burning temperature and is greater than 1550 ℃, 1200 ℃～1300 ℃ of cold rear steel billet temperature, and two cold rear board briquettes are more than 800 ℃.The high temperature of material transfers heat to the lubricating grease on bearing by conduction, radiation and convection current, therefore requires lubricating grease to have good high thermal resistance, does not at high temperature run off, and in bearing, keeps good colloidal structure; Noncoking, non-sclerous, prevent that grease-conveying tube road from stopping up and bearing is stuck.2. continuous caster adopts centralized lubrication system, lubrication management line length, and diameter is little, requires lubricating grease to have good temperature pumping performance.3. when the steel billet of crystallizer one cold formation enters two cold-zones, a large amount of water vapors, by access arrangement and bearing, require lubricating grease must have good water repelling property, are difficult for emulsification, do not run off; Under water exists situation, can keep stronger adhesivity, water-fast spray and washing away.The abrasive material invasion and attack equipment such as a large amount of iron scales, slag, iron filings and the dust impurity 4. producing in process of production, can aggravate the wearing and tearing of equipment friction means, require lubricating grease to have good abrasion resistance.5. the position such as ladle turret, rollgang bearing, fan-shaped section deflector roll bearing all belongs to heavy duty and has the operating mode of impact load, requires lubricating grease to have good extreme pressure withstand load performance.Therefore,, in order to improve the reliability of bearing and to extend its high temperature life, in the urgent need to lubricating grease for high-performance continuous casting machine, solve the problem of current existence.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of have good extreme pressure property, resistance to abrasion, and the high water resistant of good high thermal resistance and pumping and outstanding water resisting property is drenched continuous caster lubricating grease.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt perfluoroalkyl polyethers and castor-oil plant base dioctyl sebacate compound as base oil, polyureas is viscosifying agent, coordinates multiple composite additive, and each component and mass percent thereof are:
| Component | Content (mass percent) |
| Composite foundation oil | 72%～82% |
| Viscosifying agent | 16%～12% |
| Extreme pressure anti-wear additives | 3.0%～5.0% |
| High-temperature antioxidant | 0.5%～3.0% |
| Rust-preventive agent | 0.5%～1.0% |
| Water repellent agent | 0.8%～1.5% |
| Weighting agent | 1.0%～2.0% |
Base oil is that perfluoroalkyl polyethers and 30%～40% the castor-oil plant base dioctyl sebacate of mass ratio 70%～60% is compound.
Viscosifying agent is polyureas.
Extreme pressure anti-wear additives is that oil soluble organic boron molybdenum match and 40%～50% the triphenyl-thiophosphate of mass ratio 60%～50% is compound.
High-temperature antioxidant is that oil soluble organic copper salt and 30%～40% the N-phenyl-naphthylamines of mass ratio 70%～60% is compound.
Rust-preventive agent is that the benzotriazole of the lipid acid of mass ratio 60%～50% and the reactant of tetrahydroglyoxaline and 40%～50% is compound.
Water repellent agent is that mass ratio 60%～50% potassium zirconium carbonate and 40%～50% cuprous chloride are compound.
