Abstract
The invention provides a kind of fiber reinforced ceramic composite that is used for rolling mill, conticaster channel rolling liner, can selflubricating, improve 1～2 times working life than common bakelite tile, it is formed weight percentage and counts porcelain powder 20～80, glass fibre 5～40, graphite 3～15, cloth moulds 2～9, thermosetting resin 20～30 (adding).
Description
The present invention relates to fiber reinforced ceramic composite, specifically be used for the fiber reinforced ceramic composite of rolling mill, conticaster channel rolling liner.Rolling mill, the load that the casting machine raceway bears is big, operating conditions is abominable, use rolling bearing easily crushed, use the wear resisting cast iron bearing shell can not selflubricating, use cemented carbide bearing shell hardness too high, axle journal easy to wear, usually all adopt the bakelite bearing shell, this bearing shell heat-resistant antifriction poor performance, can not selflubricating, by the water flowing cooling and lubricating, in case the bakelite tile of cutting off the water supply is very easily burnt out, have to often change, become the big obstacle that influence is produced, the report of many ceramic bearings about transformation toughening is arranged in recent years, patent documentation WPI ACC NO:76-96081 */51, invented a kind of self oiling bearing member, this is the mixture that a kind of granulated filler that contains acrylate component is formed, and this bearing components also can not satisfy the requirement of rolling mill conticaster channel rolling liner, along with fiber reinforced, the reach of science of particle reinforcing material, development has the fiber reinforced of property, and the particle reinforced composite materials becomes possibility.
The purpose of this invention is to provide and a kind ofly have enough intensity and hardness, and enough plasticity and toughness are arranged, fiber reinforced ceramic composite that simultaneously can selflubricating is used for rolling mill, conticaster channel rolling liner.Fiber reinforced ceramic composite of the present invention mainly is made of body material toughened fiber and bond, it is characterized in that fiber reinforced ceramic composite of the present invention also contains oiling agent and reinforcing material, and its composition is by weight percentage:
Body material 20-80, toughened fiber 5-40, oiling agent 3-15, reinforcing material 2-9 adds bond 20-30.
Described body material is meant the porcelain powder of the various trades mark, and granularity is-200 orders.Described toughened fiber is a ceramic fiber, carbon fiber and glass fibre, the length of fiber should be between 5 microns to 50 millimeters, described oiling agent is graphite, boron nitride and molybdenum disulfide, described reinforcing material is meant the braided fabric of various cloth plastic fibers, and described bond is meant various maleimide-cyanate resin.
Fiber reinforced ceramic composite forming method of the present invention is required raw materials by weight percent to be placed in the batch mixer mix, and hot-forming, pressure is not less than 0.6 ton/centimetre
2, the base substrate that is pressed into is sent into after air dry in drying room or the baking oven and is heating and curing, and temperature should be controlled at 250 ℃.
Its mechanical property of fiber reinforced ceramic composite of the present invention is resistance to flexure 546-751kg/cm
2, impact toughness 0.175-0.248kg/cm
2The lower limit that is equivalent to metallic material, compressive strength are 1332-1355kg/cm
2Hardness HB54-64, as rolling mill, conticaster channel rolling liner, than the low life-span raising of bakelite tile cost 1-2 doubly, this material since wherein contain oiling agent can selflubricating, also be difficult for heating even cut off the water supply, do not damage axle journal, this material can be carried out the bearing shell that machining can be used for other heavy-duty machinery rotating parts, also can be used for the spigot bearing of electronic product.
