Description
(1) technical field
The present invention relates to the continuous casting technology of metallurgy industry, relate in particular to thin belt continuous casting crystal roller surface texture pattern On-Line Control Method, also relate to metal cold spraying attachment technique.
(2) background technology
Thin strap continuous casting is that liquid metal passes through the crystallization roller of placement at a high speed, and is frozen into the thick Cast Strip of 1-5mm under the effect of roll-force.The crystallization roller is the critical component in the continuously casting thin metal strips equipment, and the crystallization roll structure is mainly by inside and outside roller, formations such as left and right axle and water inlet pipe, its mainly act on be with molten metal fast cooling cool off uniformly.This requires crystallization roller material to have: good thermal conductivity; High strength and high rigidity; The thermal shock resistance of anti-rapid heat cycle; The fatigue behaviour of heat-resisting alternation.The crystallization roller mostly adopts copper-chromium-Zirconium alloy material manufacturing, the job requirement of molten steel crystallization roller is in a short period of time the roller surface to be chilled to 400～500 ℃ of temperature ranges up to 1500 ℃ of temperature, in the metallic crystal process, apply certain roll-force, bear the wearing and tearing of the etch of liquid metal and steel plate, band simultaneously.Crystallizer, roller one side contact with molten metal; The crystallization roller shell directly contacts with molten metal, the softening point of copper alloy is about 600 ℃, hardness is low relatively simultaneously, under the effect of roll-force, or when abnormal conditions occurring in producing, local softening, distortion, crackle even damage taking place easily, influence cast panel, band plate type and surface quality, increases production cost.The effective ways that address the above problem are at metals such as the surface of crystallization roller plating one deck wear-resisting Ni, Cr, Co.This technology is extensive use in traditional crystallizer.Behind overlay coating, wearability can improve, but has reduced the capacity of heat transmission of crystallization roller simultaneously.Therefore different with conventional continuous casting is thin strap continuous casting requires the heat-transfer capability of crystallization roller very high because metal must all solidify in the molten bath that the crystallization roller forms.
The key request of thin band continuous casting crystallization roller cooling is to guarantee fast and cooling uniformly, guarantees the carrying out of continuous casting and the surface quality of Cast Strip.Therefore proposed crystal roller surface is carried out coarse processing, formed certain texture, conducted, thereby the control process of setting is realized evenly cooling, is one of key technology of thin strap continuous casting to control heat.Existingly crystal roller surface is carried out the technology that roughness handles be: at the wear-resisting coat of metal of crystal roller surface plating one deck, the surface treatment of coating becomes the V-type trough, promptly trough be shaped as pointed, when molten steel and surface when contacting, molten steel can not be full of, and forms air gap between molten steel and trough.Because the thermal conductivity of gas well below the thermal conductivity of copper, forms the control to cooling velocity.Patent CN 2582783Y has improved the section configuration that crystal roller surface spins reason, is processed into lower edge shaped form or trapezoidal, reduces the thickness of air gap, when keeping evenly cooling, improves the thermal conductivity of crystallization roller.
But, because the crystallization roller in the course of the work except the requirement of at a high speed cooling, also is subjected to the effect of roll-force and the etch of molten steel.Under multiple action, crystal roller surface can wear and tear, and superficial makings in use rapidly disappears, and loses the control to cooling velocity.In addition, because the crystallization roller in use is easy to take place the adhesion of liquid metal, generally needing increases a roll surface cleaning plant, but the cleaning of roll surface is also formed wearing and tearing.The degree of depth of superficial makings is generally about 100 μ m, is 500 μ m to the maximum.The speed that polishes in the use is very fast.In case this thing happens, can influence the even cooling performance of crystallization roller.
At present, the method for recovering superficial makings is for shutting down, and changeing the crystallization roller carries out again coating and carry out texture regeneration machining processes, and this will influence the operating efficiency of crystallization roller.
