Repairing technique for vertical reducer body

Abstract

The invention discloses a repairing technique for a vertical reducer body. The repairing technique includes the following requirements: (1) surface treatment: <1> clearing old paint to expose a reducer body, removing an original welding blocking by a flat shovel, and machining a crack into a 45-degree V-shaped groove by a grinding wheel; and <2> rust and stain clearing, performing washing with gasoline, and then performing wiping with acetone for 3-5 times, and drying in air; (2) sticking technique: <1> hole repairing, pasting 3 layers of glass cloth to the inner side of a hole with a repairing agent, wherein the diameter of the first layer of the glass cloth is 4-5 cm greater than that of the hole, and the second layer and the third layer of the glass cloth are 4-5 cm greater than the previous layer respectively; and <2> crack repairing, filling the repairing agent in the V-shaped groove of the crack, performing curing at the indoor temperature for 24 hours, performing leveling through filing, then pasting three layers of glass cloth to the inner side and the outer side with the repairing agent, and performing ground flush after 12 hours. The repairing technique is reasonable in processes, is low in cost, is reasonable and coordinated in parameter collocation, is short in time, and is simple in operation.

Description

technical field [0001] The invention relates to a repair process for a vertical speed reducer body. Background technique [0002] The reducer of the rotary mechanism of the smelting furnace is in danger of being damaged during production, which will cause cracks at the bottom of one side of the casing, and the upper part of one side will be pierced to form a hole of 0-100mm. Due to the large casing, the weldability of cast iron is poor. However, the existing restoration scheme for the vertical reducer body has unreasonable process arrangement, numerous processes and long time, which can no longer meet the requirements and needs to be improved to improve performance. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a repair process for the vertical reducer body with reasonable process, simple operation, short time and low manufacturing cost. [0004] In orde...
