Problems solved by technology

In the prior art, steel rollers or mullite rollers are used in heat treatment furnaces. In the heat treatment furnace work, the temperature is high, and the steel rollers are easily deformed at high temperatures, which makes the goods may deviate in the furnace and is difficult to control.
The flatness of the metal plate is affected. At the same time, the steel roller is compatible with the coating on the metal surface, and it is easy to generate accumulation on the surface of the roller, which will scratch the surface of the metal plate.

Embodiment Construction

[0013] The invention discloses a fused silica metallurgical roller, such as figure 1 As shown, it includes a ceramic sleeve 1, a steel shaft 2 passing through the ceramic sleeve 1, and the outer surface of the ceramic sleeve 1 is provided with a sandblasting layer 3 with a thickness of 4-20 microns. In order to increase the strength of the roller, the ceramic sleeve 1 adopts a hollow fused silica sleeve.

[0014] The metallurgical roller of the present invention adopts fused quartz instead of steel roller or mullite roller, which increases the strength of the roller, and due to the design of sandblasting on the outer surface of the casing, the goods are not easy to shift on the roller. The flatness of the sheet metal surface will not be affected.

[0015] The present invention still has many specific implementation modes, and all technical solutions formed by adopting equivalent replacement or equivalent transformation all fall within the protection scope of the present inven...

Abstract

The invention provides a fused quartz metallurgic roller, which comprises a ceramic sleeve and a steel shaft passing through the ceramic sleeve. A sand blasting layer is arranged on the outer surface of the ceramic sleeve. In the metallurgic roller, the fused quartz replaces a steel roller or mullite roller and the roller strength is improved; moreover, due to the sand blasting design on the outer surface of the sleeve, articles on the roller is not easy to deviate. The flatness of a meal plate surface is not influenced.

Description

technical field [0001] The invention relates to a metallurgical roller, in particular to a metallurgical roller suitable for a metal element heat treatment furnace. Background technique [0002] Heat treatment furnaces are divided into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are collectively referred to as industrial furnaces that perform various metal heat treatments on metal workpieces. In the prior art, steel rollers or mullite rollers are used in heat treatment furnaces. During the working process of heat treatment furnaces, the temperature is high, and the steel rollers are easily deformed at high temperatures, so that the goods may deviate in the furnace, which is difficult to control. The flatness of the metal plate is affected. At the same time, the steel roller is compatible with the coating on the metal surface, and it is easy to generate tumors on the surface of the roller, which ...
