In realizing process of the present invention, the defective such as the inventor finds to exist at least in the prior art that energy loss is large, product poor mechanical property and yield rate are low.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of high-temperature metal extrudate insulation heat-preservation cylinder, to realize high insulating effect, the advantage that energy loss is little, the product mechanical property is good and yield rate is high.
For achieving the above object, the technical solution used in the present invention is: heat-preservation cylinder is used in a kind of high-temperature metal extrudate insulation, comprises cylindrical metal shell, and the formula of pasting is arranged on the inwall of described cylindrical metal shell and the insulating brick of combination molding bonded; At the inwall of described insulating brick, spaced radial offers a plurality of grooves, embeds the METAL HEATING PROCESS silk that interrupted setting is arranged in described a plurality of grooves; Be complementary with the METAL HEATING PROCESS silk of described interrupted setting, also be provided with a plurality of safety plugs that can optionally corresponding METAL HEATING PROCESS silk access civil power be heated as required; On the shell wall of described cylindrical metal shell, axially symmetricly be provided with a pair of handle.
Further, heat-preservation cylinder use in above-described a kind of high-temperature metal extrudate insulation, comprises also that axially symmetric or asymmetric formula is fixedly installed on described insulating brick inwall and for the pair of metal inner panel that described cylindrical metal shell is installed between shape pressuring machine exit and section bar cooling place.
Further, described pair of metal inner panel comprises that the side away from described insulating brick has the first metal inner panel of arc convex, and the second metal inner panel that has arc convex away from a side of described insulating brick.
Further, described METAL HEATING PROCESS silk is the wire that is wavy bending.
A kind of high-temperature metal extrudate insulation heat-preservation cylinder of various embodiments of the present invention is arranged on the inwall of cylindrical metal shell and the insulating brick of combination molding bonded owing to comprise cylindrical metal shell, the formula of pasting; At the inwall of insulating brick, spaced radial offers a plurality of grooves, embeds the METAL HEATING PROCESS silk that interrupted setting is arranged in a plurality of grooves; Be complementary with the METAL HEATING PROCESS silk of interrupted setting, also be provided with a plurality of safety plugs that can optionally corresponding METAL HEATING PROCESS silk access civil power be heated as required; On the shell wall of cylindrical metal shell, axially symmetricly be provided with a pair of handle; Can be arranged between shape pressuring machine exit and section bar cooling place, in the segment distance (or water or mist) cooling begins from the shape extruder outlet to wind, the thermometal section bar is incubated, makes the shape of heat in this segment distance, not have very large thermal loss; Thereby can overcome in the prior art that energy loss is large, product poor mechanical property and the low defective of yield rate, to realize high insulating effect, the advantage that energy loss is little, the product mechanical property is good and yield rate is high.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the present invention.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Description of drawings
