Problems solved by technology
[0015] The technical problem to be solved by the present invention is that the furnace rolls in the prior art are easy to form nodules on the surface of the rollers, which will cause defects on the surface of the metal material, greatly reducing the qualified rate of metal sheet products; if the furnace rolls are nodules, Cleaning or replacing furnace rolls is time-consuming and laborious, which greatly affects production efficiency. It is not suitable for large-scale assembly line production. Moreover, manual cleaning has technical problems such as potential safety hazards. However, it provides an annealing furnace for heat treatment of thin plate metal materials. Furnace roller combination device

Embodiment Construction
[0031] At present, in the production process of roller hearth heat treatment furnaces, it is generally reported that the hearth rolls are noduled (the hearth rolls mentioned in the present invention are all furnace rolls 4), resulting in roll marks on the lower surface of the steel plate, resulting in large-area defects in the steel plate, Even cause waste because of this, have a strong impact on product surface quality. Therefore, the nodulation problem of the furnace roller 4 has seriously affected normal production, and has also puzzled industrial furnace companies and steel production enterprises. The present invention is aimed at the nodules on the surface of the supporting and conveying furnace rollers 4 for heat treatment of thin plate metal materials in a high temperature state, and invents a combination of online cleaning, preventing or weakening the surface nodules of such supporting and conveying furnace rollers 4 Device and method for removing nodules.

The invention discloses a furnace roller combination device of an annealing furnace applied to a lamellose metal material thermal treatment process. The device comprises a furnace roller, a furnace roller base and a furnace roller driving device, wherein the furnace roller is installed on the furnace roller base; the furnace roller combination device also comprises a furnace roller nodule self-clearing device; the furnace roller nodule self-clearing device is arranged at one side of the furnace roller; and the most top end of the furnace roller nodule self-clearing device and the rotation surface of the furnace roller are in line contact with pressure when in work. By using the technical scheme, nodular materials can be prevented from leaving imprints on the surface of the lamellose metal material, so that the smooth surface of the lamellose metal material is not damaged and the degradation of the quality of the lamellose metal material or the generation of waste products is not caused; and simultaneously, the furnace roller combination device has the characteristics of simple structure, good high-temperature resistant property, long service life and the like, and is safe and reliable to use.
Description
technical field [0001] The invention belongs to the technical field of production equipment manufacturing used in the steelmaking and ironmaking production process, and in particular relates to a furnace roller combination device applied to an annealing furnace in the heat treatment process of thin plate metal materials. Background technique [0002] At present, in the metallurgical production process, the roller hearth continuous heat treatment furnace is suitable for heat treatment processes such as annealing, normalizing, high temperature tempering and quenching of steel plates, steel pipes, section steel and wire rods. Because the steel processed by the roller hearth furnace has good quality, high output and low cost, and realizes mechanized and automatic operation at the same time, it has obvious advantages over the intermittent production heat treatment furnace, so it is widely used. The heat treatment process is applied to the process of improving the properties of th...
