Abstract
The utility model relates to a long-life durable ground roller, which comprises a roller (1) arranged on a roller seat (5), wherein the roller (1) is an elongated roller, and the outer surface of the roller (1) is provided with a wear-resistant and pressure-resistant layer (6); bearing seats (7) are arranged in the two ends of the roller (1), and the roller shaft (3) is arranged in the bearing seats (7) through the totally-enclosed bearings (2); a water retaining cover (4) is arranged outside the totally-enclosed bearing (2); the water retaining cover (4) is made of high-temperature resistant materials. The utility model relates to a long-life durable ground roller, steel billet are not fragile when the dephosphorization of water under high pressure, guarantee the normal operating of steel billet dephosphorization work.
Description
Technical Field
The utility model relates to a long-life durable ground roller.
Background
The steel is oxidized at high temperature to form a layer of compact iron scale (phosphor scale) on the surface, and if the iron scale cannot be removed before rolling, the iron scale can be pressed into the surface of the steel strip by a roller in the rolling process to influence the surface quality of the steel strip, and the residual iron scale can accelerate the abrasion of the roller and reduce the service life of the roller. If the strip steel needs to be acid-washed, the residual iron oxide scale can increase the difficulty of acid-washing and increase the acid consumption. Therefore, before billet rolling, it is necessary to remove the scale on the surface, and a method of removing the scale by the mechanical impact of high-pressure water (high-pressure water dephosphorization) is currently the most effective method.
However, when high-pressure water is used for dephosphorization, the ground roller is easily damaged after being impacted by the high-pressure water, and particularly, the bearing of the ground roller is easily damaged after being directly impacted by the high-pressure water, so that the normal operation of the roller shaft is influenced, and the normal operation of the billet dephosphorization work is finally influenced. Therefore, a floor roller which is not easy to damage and has long service life and durability when steel billets are dephosphorized by high-pressure water is urgently needed at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects and provide a long-life durable ground roller which is not easy to be damaged when the steel billet is dephosphorized by high-pressure water.
The purpose of the utility model is realized like this:
a long-life durable ground roller comprises a roller arranged on a roller seat, wherein the roller is a lengthened roller, and a wear-resistant and pressure-resistant layer is arranged on the outer surface of the roller; bearing seats are arranged in the two ends of the roller, and the roller shaft is arranged in the bearing seats through a fully-closed bearing; a water retaining cover is arranged outside the totally-enclosed bearing; the water retaining cover is made of high-temperature resistant materials.
The utility model discloses durable ground roller of longevity, the roller adopts heat-resisting wear-resisting steel to make.
The utility model discloses durable ground roller of longevity has following advantage:
the length of the roller in the long-life durable ground roller of the utility model is longer than that of the conventional ground roller, and the roller is made of heat-resistant and wear-resistant steel, and the outer surface of the roller is provided with a wear-resistant and pressure-resistant layer, so that the hardness of the roller is enhanced, and the roller is wear-resistant and pressure-resistant and is more long-life durable; the bearing seats are arranged in the two ends of the roller, the roller shaft is installed in the bearing seats through the fully-closed bearing, the fully-closed bearing can block muddy water, the muddy water is prevented from directly impacting the inside of the bearing and damaging the bearing, the water retaining cover is arranged outside the fully-closed bearing and made of high-temperature-resistant materials, the high-temperature billet is prevented from being damaged, the water retaining cover plays a further role in protecting the fully-closed bearing, and the high-pressure water is prevented from directly impacting the fully-closed bearing.
