Abstract
Description
本発明は、製鉄設備等の軸受や歯車に使用することができる非延焼性グリース組成物に関する。詳しくは、本発明は、高温のスケール等が飛散して、グリースに着火し、火災が懸念される箇所に使用可能な非延焼性グリース組成物に関する。 The present invention relates to a non-fire spread grease composition that can be used for bearings and gears of steelmaking equipment and the like. More specifically, the present invention relates to a non-fire spread grease composition that can be used in a place where a high-temperature scale or the like scatters and ignites grease to cause a fire.
製鉄設備、鍛造設備などの塑性加工設備の軸受や歯車の潤滑にはグリースが多用されている。製鉄設備に使用される軸受の潤滑環境は厳しく、連続鋳造設備の軸受は、高温度の環境の中で極めて低速で回転し、荷重も大きいことから、軸受の軌道面において潤滑膜の形成が不十分となり、さらに、水やスケールも混入することから、軸受は極めて厳しい環境の中で稼働している。
鉄鋼用圧延機の転がり軸受や鍛造プレスのジャーナル軸受などは、耐熱性、耐荷重性及び耐久性が要求される製鉄用機械等の特に過酷な荷重がかかる回転、摺動機構に係る潤滑箇所を多く有している。
これらの設備は高温に曝されるため、使用済みのグリースが設備の下に垂れ落ちて堆積し、堆積したグリースが高温に曝されたり、スケールが飛散したりした場合にグリースに着火し、それに起因する火災が問題視されている。このような火災が発生しないよう、通常、垂れ落ちたグリースを手で除去している。しかし、手が入り難いような狭い場所に垂れ落ちて堆積したグリースの除去は困難である。万一火災が発生したとしても、火災が直ちに発見されれば消火は容易であるが、自動化が進んだ設備では人手が少なく、必ずしも火災が直ちに発見されるとは限らない。火災の発見が遅れると、消火が困難となり、あるいは不可能となることも起こり得る。従って、グリースには自己消火性が求められている。
特許文献１には、自己消火性に優れるグリース組成物が開示されている。
特許文献２には、着火温度を高くし、自己消火性及び耐荷重性に優れるグリース組成物が開示されている。
特許文献３には、グリース組成物の消火助剤の一例として多価アルコールが使用されている。
Grease is often used to lubricate bearings and gears in plastic working equipment such as steelmaking equipment and forging equipment. The lubrication environment of bearings used in steelmaking equipment is harsh, and bearings in continuous casting equipment rotate at extremely low speeds in a high temperature environment and have a large load, so the formation of a lubricating film is not possible on the bearing surface. Bearings operate in extremely harsh environments, as they are sufficient and also contain water and scale.
Rolling bearings for rolling mills for steel and journal bearings for forging presses are used for lubrication points related to rotation and sliding mechanisms that are subject to particularly harsh loads such as iron making machines that require heat resistance, load resistance and durability. I have a lot.
Since these facilities are exposed to high temperatures, used grease drips and accumulates under the equipment, igniting and igniting the grease when it is exposed to high temperatures or the scale is scattered. The resulting fire is seen as a problem. To prevent such a fire, the dripping grease is usually removed by hand. However, it is difficult to remove the grease that has fallen and accumulated in a narrow space that is difficult to reach. Even if a fire should occur, it is easy to extinguish the fire if it is found immediately, but the equipment with advanced automation requires less manpower, and the fire is not always found immediately. Delayed detection of a fire can make it difficult or even impossible to extinguish the fire. Therefore, grease is required to have self-extinguishing properties.
Patent Document 1 discloses a grease composition having excellent self-extinguishing properties.
Patent Document 2 discloses a grease composition having a high ignition temperature and excellent self-extinguishing property and load bearing property.
In Patent Document 3, a polyhydric alcohol is used as an example of a fire extinguishing aid in a grease composition.

本発明の非延焼性グリース組成物は、耐熱性及び耐荷重性能を維持しつつ、従来の非延焼性グリース組成物よりも非延焼性が向上している。したがって、本発明のグリース組成物は、耐熱性にも優れ、高荷重（高面圧下における荷重であり、熱間圧延で要求される）又は衝撃荷重（急激に加えられた荷重であり、鍛造設備で要求される）条件下の運転にも耐えられる一方、製鉄設備等の設備が高温に曝される環境で使用しても自然に消化して延焼しにくいことから、火災の危険性が低い。 The non-fire spread grease composition of the present invention has improved fire spreadability as compared with the conventional non-fire spread grease composition while maintaining heat resistance and load bearing performance. Therefore, the grease composition of the present invention is also excellent in heat resistance, and is either a high load (a load under high surface pressure and required for hot rolling) or an impact load (a suddenly applied load and forging equipment). While it can withstand operation under the conditions (required by), the risk of fire is low because it is difficult for the fire to spread naturally even if it is used in an environment where equipment such as iron making equipment is exposed to high temperatures.

The load-bearing additive used in the present invention is a sulfur-based load-bearing additive. The grease composition of the present invention preferably contains neither a phosphorus-based load-bearing inhibitor nor a sulfur-phosphorus-based load-bearing inhibitor. Generally, the phosphorus content that can be contained in the grease is derived from a load-bearing inhibitor (for example, zinc dithiophosphate (ZnDTP), molybdenum dithiophosphate (MoDTP), amine phosphate), and a friction modifier (for example, for example). Although some are derived from (phosphate ester) and the like, the grease composition of the present invention has a high concentration of phosphorus element of 100 ppm. As a guide, in the case of ZnDTP, which is a typical load-bearing inhibitor, 0.1 to 0.125% by mass corresponds to 100 ppm. In the case of phosphoric acid ester, which is a typical friction modifier, for example, in the case of butyl phosphate or tertiary alkylamine dimethyl phosphate, 0.07 to 0.106% by mass corresponds to 100 ppm. Although not bound by any theory, the high phosphorus concentration in the grease composition of the present invention is 100 ppm, so that many of the flash points are around 200 ° C., which is lower than the operating environment temperature of the grease. Although it contains a certain polyhydric alcohol, it is considered that it can exhibit non-spreading property.
本発明で使用できる硫黄系耐荷重添加剤として、硫化オレフィン、ポリスルフィド及び硫化油脂が挙げられる。これらは、単独でも２種以上を組み合わせて使用することもできる。
