Abstract
The invention provides a fiber reinforced ceramic composite material used for raceway bearing bushes of a rolling mill and a continuous casting machine, which enables self lubricating, compared with common Bakelite bearing bushes, service life of the raceway bearing bushes is increased by 1-2 times, and the fiber reinforced ceramic composite material comprises the following components by weight percentage: 20-80% of porcelain cement, 5-40% of glass fiber, 3-15% of graphite, 2-9% of cloth plastic and 20-30% of thermosetting resin (additionally applied).
Description
The present invention relates to fiber reinforced ceramic composite, specifically for rolling mill.The fiber reinforced ceramic composite of conticaster channel rolling liner.Rolling mill, the load that continuous caster raceway bears is large, working conditions is severe, use rolling bearing easily crushed, use antifriction cast iron bearing shell can not self-lubricating, use Wimet bearing shell hardness too high, axle journal easy to wear, usually all bakelite bearing shell is adopted, this bearing shell heat-resistant antifriction poor performance, can not self-lubricating, by water flowing cooling and lubricating, once cut off the water supply, bakelite tile is very easily burned, have to often change, become the large obstacle that impact is produced, there is the report of many ceramic bearings about transformation toughening in recent years, patent documentation WPIACCNO:76-96081X/51, invent a kind of self lubricating bearing member, this is the mixture that a kind of granulated filler containing acrylate component forms, this bearing components also can not meet the requirement of rolling mill conticaster channel rolling liner, along with fiber reinforced, particulate reinforcing material the reach of science, development has the fiber reinforced of property, the matrix material of particulate reinforcement becomes possibility.
The object of this invention is to provide and a kind of there is enough intensity and hardness, and have enough plasticity and toughness, simultaneously can the fiber reinforced ceramic composite of self-lubricating, for rolling mill, conticaster channel rolling liner.Fiber reinforced ceramic composite of the present invention, is formed primarily of body material toughened fiber and bonding agent, and it is characterized in that fiber reinforced ceramic composite of the present invention also containing lubricant and supporting material, its composition is by weight percentage:
Body material 20-80, toughened fiber 5-40, lubricant 3-15, supporting material 2-9, additional bonding agent 20-30.
Described body material refers to that the porcelain Powder Particle Size of the various trade mark is-200 orders.Described toughened fiber is ceramic fiber.Carbon fiber and glass fibre, the length of fiber should be between 5 microns to 50 millimeters.Described lubricant is graphite, boron nitride and molybdenumdisulphide, and described supporting material refers to the cloth of various cloth plastic fiber, and described bonding agent refers to the thermosetting resin of various modification.
Fiber reinforced ceramic composite forming method of the present invention is placed in mixer by the raw material of required weight percent to mix, hot-forming, pressure is not less than 0.6 ton/centimetre 2, the idiosome be pressed into is sent in kiln or baking oven and is heating and curing after seasoning, and temperature should control at 250 DEG C.
Fiber reinforced ceramic composite of the present invention, its mechanical property is bending strength 546-751kg/cm2, impelling strength 0.175-0.248kg/cm2.Be equivalent to the lower limit of metallic substance, compressive strength is 1332-1355kg/cm2, hardness HB54-64 is as rolling mill, conticaster channel rolling liner, lower than bakelite tile cost, life-span improves 1-2 doubly, this material, due to wherein can self-lubricating containing lubricant, be also not easily generated heat even if cut off the water supply, is not damaged axle journal, this material can carry out the bearing shell that mechanical workout can be used for other heavy-duty machinery rotating elements, also can be used for the spigot bearing of electronic product.
