Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of furnace roller technology, especially relates to an easy-to-maintain casting furnace roller. BACKGROUND

[0002] Furnace rollers usually refer to rollers used for sliding, supporting or conveying materials during steel smelting or heat treatment, which often need to withstand harsh environments such as high temperature, high pressure and mechanical wear, and are therefore usually made of high-strength, high-temperature-resistant materials such as cast steel, cast iron and alloy steel.

[0003] For example, the Chinese patent with the announcement number CN212645328U discloses an easy-to-maintain casting furnace roller, which comprises a furnace roller body, a cooling mechanism provided on the furnace roller body, the cooling mechanism comprising a cooling maintenance cover, a cooling cavity, a cooling medium connecting pipe, a T-shaped block, and a mounting seat, the cooling maintenance cover being symmetrically formed with furnace roller grooves at the top and bottom, the cooling maintenance cover being provided with the cooling cavity, the cooling maintenance cover being connected to the cooling medium connecting pipe at the top near the front and rear sides, the cooling maintenance cover being welded with the T-shaped block at the top end, the T-shaped block being symmetrically provided with the mounting seat welded with the furnace roller body at both ends, the mounting seat being formed with a mounting seat groove at the contact surface with the T-shaped block, and the T-shaped block being formed with connecting holes near both ends.

[0004] Although the above-mentioned disclosed patent solves the problem that the furnace roller needs to be disassembled and cleaned when it is maintained, the cooling maintenance cover in the patent is connected to the furnace roller shell by screws, which still needs to be disassembled by tools during subsequent maintenance, increasing the complexity of the operation and failing to achieve truly fast, convenient and easy maintenance. In addition, due to the effects of high temperature, vibration and other environmental factors, the screws connecting the cooling maintenance cover are prone to loosening after long-term use of the furnace roller, which will directly lead to a decrease in the connection tightness between the cooling maintenance cover and the furnace roller shell, and even may cause the risk of falling off, affecting the normal operation of the cooling system and posing a potential threat to production efficiency and equipment safety.
