Abstract
Description
Technical Field
[0001] The invention relates to the technical field of auxiliary devices for laying refractory materials in metallurgical furnaces, and in particular to a lead screw with a thread cleaning device and a use method thereof. Background Art
[0002] Lead screws are crucial tools used in the construction of refractory masonry for metallurgical furnaces. Large quantities of water-containing refractory slurry and other materials are used during the masonry process. As a temporary support structure for the refractory masonry, lead screws frequently bear the weight of the masonry and maintain stability. Their threads are inevitably exposed to this complex and harsh environment. During actual operation, impurities such as slime easily accumulate on the lead screw threads. This slime is primarily composed of a mixture of solid particles remaining after the evaporation of water from the refractory slurry, dust from the furnace, and other airborne impurities. Over the course of continuous use, slime accumulates on the lead screw threads. Currently, these impurities are primarily removed manually using tools such as wire brushes. This is not only labor-intensive and time-consuming, but also, due to the complex thread structure, it is difficult to completely remove impurities deep within the thread crevices. Residual impurities will have many adverse effects on the normal use of the screw: on the one hand, impurities will destroy the fitting accuracy of the thread, causing problems such as jamming and uneven transmission between the screw and the screw sleeve, affecting the stability and reliability of the support; on the other hand, long-term residual impurities will accelerate thread wear, shorten the service life of the screw, and increase equipment replacement costs and maintenance difficulty.
