Method for repairing roller head for rock wool production

Abstract

The invention discloses a method for repairing a roller head for rock wool production. The method comprises the following steps of taking out a damaged roller head, cutting off defect parts of the roller head and a roller neck of a roller, polishing and cleaning an end face, inserting the roller head and the roller neck into a pouring mold sand box, preheating the parts of the roller head and theroller neck, which need to be welded, pouring molten iron into the pouring mold sand box, welding the roller head and the roller neck, and after the molten iron is poured and cooled to the normal temperature, completing welding between the roller head and the roller neck; and conducting repair welding and polishing treatment on the parts with the welding defects through welding and polishing equipment. According to the method, through cutting off the defect parts of the roller head and the roller neck firstly, polishing and cleaning the end face, and then conducting pouring and welding betweenthe roller head and the roller neck in the pouring mold sand box, firm connection between the roller head and the roller neck is guaranteed; and meanwhile, repair welding treatment is conducted on the connecting position through the welding and polishing equipment, so that the repair rate of the roller is high, and the repair effect is good.

Description

technical field [0001] The invention relates to the technical field of repairing roller heads for rock wool production, in particular to a method for repairing roller heads for rock wool production. Background technique [0002] Rock wool originated in Hawaii. After the first volcanic eruption on Hawaii Island, the residents on the island found strands of melted soft rocks on the ground. This is the rock wool fiber that humans first recognized. The production process of rock wool is actually simulated. The natural process of Hawaiian volcanic eruption, rock wool products are made of high-quality basalt, dolomite, etc. After collecting agent, anti-dust oil and water-repellent agent, they are collected by the cotton collector, passed through the pendulum method, and then solidified and cut by the three-dimensional method to form rock wool products with different specifications and uses. [0003] Today, with the rapid development of human civilization, the natural environment...

AI Technical Summary

Problems solved by technology

[0004] Rock wool is an ideal building insulation material. In the production process of rock wool, the roller is one of the most commonly used tools. After a period of use, the roller will be damaged due to various external factors. In severe cases, the break between the roll head and the roll neck may occur. After the break between the roll head and the roll neck, it is generally scrapped, which will cause great waste. Although some methods can be used to repair the roll head Some repairs are carried out between the roll neck and the roll neck, but the overall repair effect is poor, and the roll is inconvenient to use
