Description
Technical Field
The invention belongs to the technical field of substrate glass manufacturing, and particularly relates to a device and a method for rapidly measuring thermal centering of a stirrer.
Background
The installation of the platinum channel in a cold state mainly ensures the accurate conversion of design dimensions, and each key butt joint area is provided with a normal temperature reference for the comparison accounting of a thermal state reference after the temperature rise is completed. The platinum channel is assembled and built at normal temperature, and then the whole channel is heated according to the heating file, and expansion displacement occurs at each region of the channel along with continuous temperature rise, except for the butt joint reservation in the length direction, the stirring region needs to consider the thermal expansion of the stirring tank body and the stirrer, although the stirring tank body adopts a fixed mode on the mounting structure, the stirring tank body is not subjected to horizontal displacement at high temperature, only the axial expansion in the vertical direction is reserved, the stirrer is mounted in the tank body at normal temperature, and four reference lengths in the circumferential direction at the cold state are confirmed, so that the stirrer is ensured to be positioned at the center of the stirring tank at normal temperature. After the temperature is raised in place, the displacement of the stirrer and the tank body in the horizontal direction or the expansion change of the stirrer and the tank body can exist, so that the stirrer is required to be subjected to secondary centering in a thermal state, and the stirrer is ensured to be always positioned at the center of the stirring tank.
In the actual thermal state centering process, because the temperature of the stirring top area is up to nearly thousand ℃, operators need to wear special high-temperature resistant clothes to operate, the insulation structure of the stirring top needs to be removed before operation, the whole process takes tens of minutes, and centering measurement under the thermal state is performed after the removal is completed.
