Description
Technical field
The present invention relates to the industrial furnace Thermal Equipment, refer to particularly a kind of CSP process furnace high-temperature furnace roller.
Background technology
Furnace roller is most important equipment in CSP (Compact Strip Production, the compact output strip line) roller hearth type heating furnace, is the axis water cooled rolls, and its major function is support and the transmission of thin plate strand in the stove, and online amount greatly.It mainly consists of by supporting between roll shaft, water-cooled steel pipe, the metal body of roll, heating resisting metal collars, collars fire-resistant material heat insulation lining etc., and its furnace roller complex structure, cost of manufacture are high; 4 load-bearing of enclosing the heating resisting metal collars of wide approximately 80mm by welding layout on the body of roll, carry out the support of thin plate strand, positive and negative rotation and speed adjustment and collars and thin plate strand spare friction-driven by furnace roller, finish the conveying of strand in stove and the adjusting of surge time, realize the heat-processed in the strand stove, furnace roller and strand noncontact part all adopt refractory materials thermal insulation layer parcel, guarantee support strength and rigidity under the furnace roller applied at elevated temperature condition, reduce the loss of furnace roller water-cooled, thereby, the furnace roller Working environment is the most abominable, not only to bear high temperature, furnace gas washes away and corrosion, but also need bear strand weight, bump and frictional influence, cause the fire-resistant material heat insulation lining serious with the collars physical abuse, the creep of collars metallic high temperature, oxidation and dross have not only affected the Comprehensive service life of furnace roller, but also cause casting billet surface impression and the black seal of water-cooled, especially furnace temperature is greater than 1200 ℃ roller hearth type heating furnace furnace roller, and the damage situation is even more serious.This shows, the CSP roller hearth type heating furnace with the water-cooled furnace roller have that quantity is large, working conditions is abominable, water-cooled intensity is large, complex structure, the serious characteristics of damage, and furnace roller is the key part fragile in the roller hearth type heating furnace, that consumption is large, it also is the main composition of roller hearth type heating furnace maintenance cost, simultaneously, also be the key factor that affects strand heating quality, surface quality.For this reason, Chinese scholars is from prolonging furnace roller work-ing life, improve the interior heating quality of strand stove and surface quality angle and carried out series of studies work, as: a number of patent application is 200920304608, denomination of invention discloses a kind of roller hearth type heating furnace Novel furnace roller for the Chinese patent of " a kind of Novel furnace roller ", comprise the body of roll, water cooling tube and spindle nose, body of roll two ends are fixed with respectively spindle nose, body of roll inside is fixed with water cooling tube, several equally distributed collars of suit on the body of roll, collars adopts the Cr35Ni55W9Al2 material to make, collars wear resisting property and high-temperature oxidation resistance have not only been improved, and after wearing and tearing appear in collars, only changing collars just can, need not carry out the furnace roller integral replacing, thereby reduce the furnace roller maintenance cost; In addition, refractory mortar is installed between the collars, has both reduced the body surface temperature, prolonged again furnace roller work-ing life; But the furnace roller structure is identical with the import furnace roller with furnace roller maintenance update mode, and simultaneously, the noble metal element of superelevation content causes the collars price sharply to rise, and has no at present the report that actual production is used.To be 200920186762.X, denomination of invention disclosed stove furnace roller at the bottom of a kind of roller for the Chinese patent of " stove composite roll at the bottom of the roller " to another part number of patent application, consisted of by steel axle, collars and refractory materials, collars is fixed on the steel axle, refractory materials is located on the steel axle between the collars, characteristics are collars by ring in the steel and high temperature resistant outer shroud is compound consists of, interior ring is elongate tubular, interior ring key groove is established in the outside vertically, outer shroud is annular, inwall is established the outer shroud keyway vertically, interior ring key groove and outer shroud keyway be corresponding being harmonious one by one, is inlaid in together by key.Outer shroud is fixed on the interior ring, and interior boxing connects and is fixed on the steel axle, and then pouring fireproof material is made into furnace roller.Its advantage is: high temperature resistant head time collars smooth surface, avoid the collars steel bonding, and improve the billet surface quality; Pottery collars heat-proof quality is excellent, can tolerate very high temperature, reduces the black seal of heating steel billet water-cooled and water-cooled loss, improves the heating steel billet quality; Have the characteristics such as easy processing, few maintenance, long service life.But the brittle ceramic materials mechanical shock resistance is not enough, under the strong effect of impact, can cause the mechanical damage of ceramic outer ring in the slab course of conveying, affects its practical effect, has no at present the report that actual production is used.In addition, an international application no is that PCT/US94/03199, the world are disclosed as WO94/21978, denomination of invention is the European patent of " high-temperature roller bottom-type heating furnace furnace roller ", multiple high-temperature roller bottom-type heating furnace furnace roller structure is disclosed, all adopt refractory alloy to make collars, design by multiple multi-form furnace roller thermal insulation lining structure, water-cooling channel structure and collars structure, reach the heat insulation and collars cooling performance of strengthening the body of roll, enlarge furnace roller tolerable temperature scope, satisfied the user demand of high-temperature roller bottom-type heating furnace.But furnace roller water-cooling channel, collars and heat shield liner complex structure, manufacture difficulty are large, cause the furnace roller comprehensive cost high.Simultaneously, the reinforcement of collars cooling causes the loss of furnace roller water-cooled large, is unfavorable for that roller hearth type heating furnace is energy-conservation.Domestic once had this technology in furnace temperature less than 1200 ℃ CSP roller hearth type heating furnace report on probation, but because of work-ing life and cost is undesirable abandons.In addition, also there is the example that adopts Co50 refractory alloy collars in Italian Dexing company, be higher than the service requirements of 1200 ℃ CSP roller hearth type heating furnace to satisfy furnace temperature, but Co50 refractory alloy collars is very expensive, can't apply.Document " Baogang's science and technology " has published by Feng Liyi, Zhou Jianping and Zhang Qian write, name is called the technical article (2004 of " development of CSP heating furnace roller collars ", 30 (2)), reported production domesticization and the applicable cases of collars with the heating resisting metal material, by the material analysis to import Germany LOI company collars, C in guaranteeing steel, Ni, in the situation of the main components such as Cr, adopt and adjust microalloy Nb, Mo, Ti, Co, A1, S in the massfraction of Si and the reduction steel, the smelting means of P, finished the exploitation of collars refractory alloy, and under the condition that does not change the collars structure, obtained the effect identical with the import collars, made the collars cost 2/3; But the highest furnace temperature that collars adapts to≤1200 ℃ can not satisfy the user demand of higher furnace temperature.In sum, furnace roller work-ing life and working service cost are only considered in Patents and technical study both at home and abroad, and also need further to study with the cost degradation of furnace roller and the improvement of Integrated using performance for the high-temperature roller bottom-type heating furnace of furnace temperature greater than 1200 ℃.
