Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum silicon plate rolling, in particular to a roller preheating device for aluminum silicon plate rolling. Background Art
[0002] Aluminum silicon sheet is a composite sheet made of aluminum and silicon, which usually has excellent corrosion resistance, thermal conductivity and processing performance. Aluminum silicon sheet is widely used in the fields of construction, automobile, aerospace, etc., such as the exterior walls, roofs, interior walls and other parts of buildings, radiators, engine hoods and other parts of automobiles, and the shells of aerospace vehicles. There are many production processes for aluminum silicon sheet, one of which is hot rolling. The hot rolling method is to heat the aluminum silicon alloy to a certain temperature and then roll it into an aluminum silicon sheet of a certain thickness through a rolling mill.
[0003] During the rolling process of aluminum-silicon alloy plates heated to a certain temperature, the rollers are subjected to high temperature, high pressure, rapid cooling and heating, and alternating tensile and compressive internal stresses appear in the rollers, causing cracks on the roller surface. As the cracks progress and expand, the roller surface angles crack or even peel off. In order to protect the rollers and extend the service life of the rollers, the rollers must be preheated before rolling. At present, there are two commonly used preheating methods: 1. Steam preheating: that is, steam is introduced into the silver rolling hole before the roller is changed for preheating for more than 8 hours, and the roller surface temperature reaches 60-80C. This method has the best preheating effect; 2. Emulsion preheating: In special circumstances, when changing the roller, steam preheating is not performed. After the roller is changed, the roller is rotated at a low speed and the emulsion is sprayed for preheating for 20-30 minutes. At present, when preheating is performed by directly spraying the emulsion: 1. The contact time between the sprayed emulsion and the roller is short, and the preheating effect is not good; 2. The sprayed emulsion cannot be recovered, which will cause the emulsion flow channel to the workshop floor and pollute the workshop environment. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a roller preheating device for rolling aluminum silicon plates. The roller is preheated by spraying emulsion, and the emulsion after spraying can be gathered at the bottom of the inner cavity of the sleeve to preheat the bottom of the roller, thereby increasing the contact time between the emulsion and the roller, thereby improving the preheating effect. The emulsion after spraying can also be recovered to avoid the emulsion from polluting the workshop environment. The utility model is easy to use and can effectively solve the problems in the background technology.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
