Abstract
The utility model discloses a liquid metal guiding device in a metal casting process, and particularly to a fireproof fiber insulating riser sleeve used for guiding the liquid metal. The fireproof fiber insulating riser sleeve is mainly composed of a cylindrical barrel body, wherein 2/3 of the inner wall of the cylindrical barrel body is cylindrical while 1/3 thereof has a shape of circular truncated cone. The fireproof fiber insulating riser sleeve has the advantages of a simple structure, good thermal insulation properties, high metal liquid utilization rate and low production cost.
Description
Technical field
The utility model relates to the liquid metal guiding device in a kind of metal casting process, specifically the refractory fibre insulating riser sleeve used of a kind of liquid metal water conservancy diversion.
Background technology
At present, the insulating riser sleeve kind of using in the metal casting industry is more, traditional insulating riser sleeve is cylindrical tube, upper lower wall thickness is consistent, it is poor that this structure exists the riser buss heat-insulating property, the Heavy Weight of casting pressing port, and the basal area that casting pressing port need to cut is large, the metal liquid utilization rate is low, the weak point that production cost is high.
The utility model content
Task of the present utility model is to provide a kind of simple in structure, good heat insulating, and the metal liquid utilization rate is high, the refractory fibre insulating riser sleeve that the liquid metal water conservancy diversion that production cost is low is used.
For realizing above-mentioned task, technical solution of the present utility model is: a kind of refractory fibre insulating riser sleeve, mainly consisted of by cylindrical tube, and the inwall 2/3rds of described cylindrical tube is cylindrical, 1/3rd is truncated cone-shaped.
The utlity model has simple in structure, good heat insulating, the metal liquid utilization rate is high, the advantage that production cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of refractory fibre insulating riser sleeve mainly is made of cylindrical tube, and it is cylindrical 1 that cylindrical tube inwall 2/3rds is made, and inwall 1/3rd is made truncated cone-shaped 2.
Claims (1)
1. a refractory fibre insulating riser sleeve, comprise cylindrical tube, it is characterized in that: the inwall 2/3rds of described cylindrical tube is for cylindrical, and 1/3rd is truncated cone-shaped.
