Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, fabrication and processing simple and can the most stably realize solar heat protection heat scatter and disappear and can long time operation planet hot-rolling mill on heat-insulation and heat-preservation casing bit.
For achieving the above object, technical scheme provided by the utility model is: the heat-insulation and heat-preservation casing bit on a kind of planet hot-rolling mill, including internal lining pipe, for the fixed support fixedly mounting described internal lining pipe and the targeting port in the high-temperature pipe bar described internal lining pipe of entrance being positioned on described fixed support one end, it is characterized in that: also include the guide pin bushing being set in described internal lining pipe inner chamber, it is arranged at the heat-insulation layer between described internal lining pipe and guide pin bushing, be arranged on described internal lining pipe outer surface protects sleeve pipe and is arranged on the cooling water cavity between described internal lining pipe and protection sleeve pipe, the water inlet being connected with described cooling water cavity and outlet it is provided with on wherein said fixed support.
Preferably, described targeting port enters the bell-mouth structure of air in described guide pin bushing for ease of high-temperature pipe bar.
Preferably, described heat-insulation layer is the hollow cavity structure being made up of described internal lining pipe and guide pin bushing, is wherein filled with high chrysotile in this hollow cavity structure.
Further, described water inlet and outlet are additionally provided with the flow speed control assembly for controlling cooling water circulation flow velocity in described cooling water cavity on it.
Preferably, described its thickness of resistant to elevated temperatures asbestos material is 5mm-10mm.
Preferably, described flow speed control assembly is hand-operated valve or electrodynamic valve.
Preferably, described guide pin bushing, internal lining pipe and protection sleeve pipe are senior drawn tube.
Compared with prior art, this programme overall construction design is simple, it is easy to processing and manufacturing, and there is heat-resisting, insulation, fire-retardant effect, drastically increase the protection effect to high-temperature pipe bar, extend the stream time of hot-rolling mill, decrease the operation costs of enterprise.Specifically, due to the heat-insulation and heat-preservation casing bit in this programme, it is followed successively by for high-temperature pipe bar carrying out the heat-insulation layer of isothermal holding and having the cooling water cavity layer of cooling down effect from inside to outside, on the one hand it can ensure that the high temperature that high temperature bar is required when carrying out rolling operation to use this kind of version, prevents the heat losses of high-temperature pipe bar；On the other hand due to the most whole heat-insulation and heat-preservation casing bit, it contacts with rolling equipment main transmission casing for it, by arranging a cooling water cavity layer in outside it is prevented that the heat of high-temperature pipe bar is transferred to rolling equipment main transmission casing, thus ensure the most properly functioning of whole equipment.
