Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled steel bar production, in particular to a convenient and fast device for cleaning oxidized iron scale of continuous casting billets. Background Art

[0002] After the continuous casting billet is sent from steelmaking to steel rolling, it is converted into qualified steel through hot rolling or direct rolling. Cleaning the iron oxide scale is of great significance for the production of hot-rolled wire rod and hot-rolled steel bar.

[0003] Hot-rolled wire rod requires a smooth and excellent surface quality to meet the requirements of further processing. Therefore, improving the surface control capabilities of steel is crucial. The presence of iron oxide scale can affect the flatness and smoothness of the billet surface, which can then be inherited by the steel. Cleaning reduces surface defects and prevents iron oxide scale from being pressed into the steel during rolling, leading to uneven internal structure and reduced strength and toughness. This improves the quality and performance of the steel, ensuring superior performance in subsequent processing and use. For example, in the manufacture of automotive parts, improved surface quality can enhance the precision and reliability of these parts.

[0004] Furthermore, in the production of hot-rolled rebar, with the national call for energy conservation and consumption reduction, low-carbon, green production methods are gaining increasing attention, and the adoption of billet direct rolling is gradually increasing. Temperature control during the continuous casting process is a key factor, necessitating precise billet temperature monitoring at key locations along the roller conveyor. However, due to the high-temperature nature of casting, iron oxide scale on the billet surface can interfere with temperature measurement, requiring cleaning for accurate temperature measurement. Therefore, cleaning iron oxide scale is crucial for direct rolling of hot-rolled rebar.

[0005] With the improvement of production requirements, some companies have gradually paid attention to the cleaning of steel billet oxide scale and have made some control attempts.

[0006] For example, "Patent No. CN201920341812.0 "A device for removing oxide scale from the surface of continuous casting billets" uses a conveyor to remove oxide scale and improve the surface quality of billets, but requires additional power, which increases energy loss.

[0007] Patent number CN202221624197.2, "A spraying device for removing iron oxide scale from continuous casting billets," utilizes a water supply pipe and an air supply pipe installed above a roller table. High-pressure nozzles are used to spray the continuous casting billets with atomized water to remove iron oxide scale from their surfaces. However, the equipment is complex and requires engineering modifications.

[0008] Patent No. CN201921453610.1 "An improved device for cleaning iron oxide scale on the surface of continuous casting billets" uses a steel brush with steel wire installed on the fixed structure above the roller where the continuous casting billet runs through fixing screws. The purpose of the steel brush moving vertically with the force cannot be achieved. If the steel billet abnormally impacts the steel brush during the movement of the roller, it is easy to cause the steel brush to be damaged or scratched, posing a risk to the quality of the steel billet.

[0009] While existing billet scale removal devices can mitigate the effects of scale to a certain extent, significant room for improvement remains. Therefore, a convenient and simple scale removal device is needed. This device would eliminate energy consumption and eliminate the need for complex engineering modifications, allowing for a simple and environmentally friendly scale removal process.

[0010] Therefore, there is an urgent need to design a convenient and fast device for cleaning the iron oxide scale of continuous casting billets to solve the problems of requiring additional power, increasing energy loss, complex equipment, the need for engineering modifications, and easily causing damage to the steel brush or scratches on the billet, posing a risk to billet quality.

[0031] Example 2: Specific implementation steps using the structural form of Example 1.

[0032] 1. Use the insulation board 5 of the steel roller to select the area where the oxidized iron scale of the steel billet needs to be cleaned;

[0033] 2. A fixed sleeve is welded at the slot. The sleeve is divided into two detachable parts, the upper and lower parts, which are tightened by a screw-like method for easy disassembly. The upper sleeve 1 is provided with a top spring 1.1. The spring 1.1 has an optional elastic force and is welded and fixed to the top of the upper sleeve 1.
