Description

Roller horizontal centrifugal casting multi-degree-of-freedom intelligent infrared temperature measuring device and process method Technical Field The invention relates to the technical field of intelligent infrared temperature measurement, in particular to a roller horizontal centrifugal casting multi-degree-of-freedom intelligent infrared temperature measurement device and a process method. Background The roller is used as a key industrial consumable in the steel industry, the annual consumption is about 80 to 120 ten thousand tons, the market space of about 300 to 400 hundred million yuan is formed, and from the viewpoint of a product structure, the hot rolling working roller accounts for the highest proportion of about 55 percent, the cold rolling working roller accounts for 25 percent and the supporting roller accounts for about 20 percent. Meanwhile, about 60 to 70 ten thousand tons of waste rollers are produced each year, wherein 30 percent of the waste rollers are directly scrapped to a furnace due to the problems of cracking or peeling and the like, 40 percent of the waste rollers can be regenerated through remelting, and the waste rollers can be degraded for continuous use after 30 percent of the waste rollers are repaired through remanufacturing processes such as overlaying, surface cladding and the like. The roll is a key core component of a steel rolling production line, the service environment of the roll needs to bear high load, strong abrasion and severe cold and hot impact, the service life of the roll and the precision of a steel rolling product are directly determined by the uniformity of internal tissues, the surface hardness and the metallurgical bonding quality, and the horizontal centrifugal casting is a main flow technology for preparing a composite layer roll. In the horizontal centrifugal casting process, the temperature is a core control parameter affecting the forming quality, the organization performance and the metallurgical bonding effect of the roller, and the infrared temperature measurement technology is combined with the intelligent regulation and control of multiple degrees of freedom, so that the method is a key technical path for solving the limitations of the traditional temperature measurement mode and realizing the accurate temperature control in the roller casting process. The outer layer of the roller needs to form uniform and fine martensite or bainite structure to ensure wear resistance, the inner layer needs to form pearlite and ferrite structure with good toughness to bear rolling load, the melt solidification rate is directly related to temperature gradient under the rotation centrifugal force in the centrifugal casting process, the too high temperature can cause the too slow solidification rate, coarse grains and component segregation occur, and the hardness and wear resistance of the roller are reduced. When the temperature is too low, the melt fluidity is insufficient, defects such as air holes and shrinkage holes are easy to generate, meanwhile, a brittle phase is easy to form at the metallurgical bonding interface of the outer layer alloy and the inner layer alloy, and peeling and cracking are caused in the roll service process, so that the casting time of the middle layer and the core layer, namely the cooling temperature, is accurately measured through a temperature measuring system, and the centrifugal casting quality is greatly influenced. Disclosure of Invention The invention aims to provide a roller horizontal centrifugal casting multi-degree-of-freedom intelligent infrared temperature measuring device and a process method, which can realize flexible movement in three directions of an X axis, a Y axis and a Z axis and support omnibearing multi-angle rotation. Based on this regulating capability, the device can carry out multiple spot position, no dead angle temperature acquisition to the cold type internal wall alloy layer of roller centrifugal casting different positions, through the mode to multiunit measured data average value, effectively reduces the error of single-point temperature measurement, is showing the precision that promotes temperature detection. In order to achieve the purpose, the invention provides the following technical scheme that the intelligent infrared temperature measuring device for the multi-degree of freedom of the roller horizontal centrifugal casting comprises a cold type, a temperature measuring assembly, a cold type driving motor, a cold type universal coupling and a cold type carrier roller, and further comprises: the lifting mechanism is used for driving the temperature measuring assembly to move up and down along the Z-axis direction; the horizontal feeding moving mechanism can drive the temperature measuring assembly to move in the Y-axis direction; the axial feeding moving mechanism is used for driving the temperature measuring assembly to move along the X direction and is matched with the lifting mechanism and t
