Rotary hearth furnace support carrier roller platform-free installation and adjustment method

Abstract

The invention relates to a rotary hearth furnace support carrier roller installation method, in particular to a rotary hearth furnace support carrier roller platform-free installation and adjustment method. The method comprises the steps of preliminarily installing all support rollers in place; determining a pre-buried point A as a 0-degree rear view point for stationing of a total station on a zero line of the design position; determining the position of the center O of a circle of a rotary hearth furnace after the preliminary installation of rotary hearth equipment is completed, and erectingthe total station outside of the circle at which the support rollers are located, and on a point B on an extension line of AO; stationing in the total station, setting the azimuth as 0, establishinga rectangular plane coordinate system with a point O as the origin, and measuring the actual position coordinates of the support rollers one by one; inputting the measured actual coordinates of all the rollers into computer aided design (CAD) by taking the point O in the design drawing of the rotary hearth furnace in the CAD as the coordinate origin, and resolving the difference between the actualmeasured coordinates and design values into a radial direction deviation a and a tangential direction deviation b; giving the result an operator, carrying out fine adjustment on the support rollers one by one, and then fixing the support rollers. The rotary hearth furnace support roller platform-free installation and adjustment method can shorten the construction period and reduce the cost.

Description

technical field [0001] The invention relates to a rotary hearth furnace, in particular to a method for installing support rollers of a rotary hearth furnace. Background technique [0002] The installation of rotary hearth furnace equipment is an emerging process technology. The current installation method roughly refers to the installation technology of ring furnace, but it is slightly different. Generally, the center of the circle is positioned by pouring profiled steel at the center of the circle to build a platform to keep it stable, and finally use the measurement and positioning technology to determine the specific position of each idler roller. However, because there is also pipeline equipment to be installed at the central location, there is a conflict between the construction period between equipment installation and pipeline installation, so the construction period can only be extended, resulting in the phenomenon of idle work. When the equipment installation is fi...

However, because there is also pipeline equipment to be installed in the central location, there is a conflict between the construction period between equipment installation and pipeline installation, so the construction period can only be extended, resulting in the phenomenon of idle work

When the equipment installation is finally completed, the positioning platform in the center needs to be dismantled, which is time-consuming, laborious, and requires the assistance of hoisting machinery, resulting in unnecessary waste of resources
