Abstract

The invention relates to a hot rolling and finish rolling lubricating agent for a copper and copper alloy sheet strip. 15# oil for a total-loss system is used as base oil and is matched with various composite additives including an anti-wear agent, an oiliness agent, an anti-oxidant and anti-corrosive additive, a bactericide, an anti-foaming agent, a metal deactivator, an emulsifying agent and a coupling agent. The hot rolling and finish rolling lubricating agent has the necessary performances of medium separation, friction reduction and wear resistance, and is capable of keeping metal soap with mixed oil in any form in a suspended state, inactive, stable in chemical performance for rolled pieces and rollers, capable of avoiding generating adhesive substances on rolling machines and rolled products and favorable in scale removal capability so as to clear away the finish rolling lubricating agent possibly falling on the sheet strip or roller bed.

Description

Copper and Plate and strip of copper alloys hot fine rolling lubricant

Technical field

The invention belongs to copper and Plate and strip of copper alloys hot fine rolling field of lubricant.

Background technology

Copper and Plate and strip of copper alloys are most widely used classes in heavy non-ferrous metal, and its production method, can be divided into hot rolling method and cold-rolling practice by the cogging mode of ingot casting; Can be divided into piece formula method and belt method by rolling mode.Production method has both at home and abroad at present: semicontinuous ingot casting heating-hot rolling-cold-rolling practice, horizontal continuous-casting volume base-rolling cold-rolling practice, block strand-cold rolling and extrusion billet-cold-rolling practice.During copper and Plate and strip of copper alloys are produced, blank surface milling (milling face) technique after extensive employing hot rolling both at home and abroad.

Hot rolling copper material technology lubricant has three effects: the one, and cooling roll, makes it keep reasonable temperature; The 2nd, rolled piece is applied to thermal shocking, cracked its surperficial oxide skin also washes away, and prevents that they are pressed in rolled piece, produces interlayer; The 3rd, avoid, between roll and rolled piece, adherent phenomenon occurs.Copper material hot-rolled temperature is at 750～850 DEG C, and temperature is higher, does not conventionally directly use full oil type technology lubricant, and often uses emulsion or water as cooling-lubricant.But copper powder is easily reacted with the active substance in emulsion and formed Copoloid, make emulsion shortening in work-ing life.Meanwhile, the lubricant viscosity of emulsion is one of key factor determining its rolling efficiency, and therefore, the performance that hot rolling copper material finish-rolling process lubricant should have is: use low viscous base oil; Possess necessary separation medium, reduce friction, wear-resistant performance; There is the ability that makes assorted oil metallic soap in any form remain on suspended state; Must be inactive, be all stable to rolled piece and its chemical property of roll; Can prevent from producing bur on milling train and rolled products, there is good de-sludging performance, to remove the rolling lubricant that may fall on Strip or roller-way.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of possess necessary separation medium, minimizing friction, wear-resistant performance, have and make assorted oil remain on the ability of suspended state, stable chemical performance, can prevent from producing bur on milling train and rolled products, there is copper and the Plate and strip of copper alloys hot fine rolling lubricant of good de-sludging performance.
