Description

Casting system for small scroll

Technical Field

The utility model relates to the field of titanium alloy casting, in particular to a casting system for a small volute.

Background

The runner used in casting of the currently produced 9080 type volute product is too long, but the size of the furnace mouth is 490mm, the size of the runner is 500m, the runner exceeds the size of the furnace mouth of a smelting furnace, the return rate material cannot be directly fed into the furnace when used, and the return rate material can be fed into the furnace after being divided, so that the use is extremely inconvenient; and the product quantity is large, and the process yield is low. Resulting in waste of labor and smelting costs.

Disclosure of Invention

The utility model aims at: the casting system for the small scroll is used for solving the problem that the prior product is inconvenient to use due to overlong pouring gate in casting.

The technical scheme adopted by the utility model is as follows: the utility model provides a casting system that small-size volute was used, includes the sprue, sprue lower extreme intercommunication has the cross, the cross is "cross" form setting, just the length of cross is less than 490mm, the side of cross all is provided with into the fire gate, it is cascaded to advance the fire gate, the one end and the die cavity intercommunication of cross are kept away from to the fire gate.

The cross section area ratio between two sections of pipelines of the fire inlet is 1:0.6, the joint between the two sections of pipelines adopts arc transition, and the joint between the transverse runner and the fire inlet also adopts arc transition, so that the molten metal can smoothly and stably change direction.

In conclusion, by adopting the technical scheme, the utility model has the beneficial effects that:

according to the utility model, the length of the cross gate is shortened, so that the furnace return materials can be directly fed into the furnace; the stepped fire feeding design is utilized, so that the flow speed of molten steel and the slag blocking effect are improved, and the defects of cold insulation and slurry eyes are reduced.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Fig. 1 shows: the utility model provides a casting system that small-size volute was used, includes sprue 1, and sprue 1 lower extreme intercommunication has runner 2, and runner 2 is "cross" form setting, and runner 2's length is 350mm, is less than the width 490mm of fire hole, and runner 2's side all is provided with into fire hole 3, advances fire hole 3 and shares two sections pipelines, and the contained angle between two sections pipelines is 90, advances fire hole 3 and is the ladder type, advances fire hole 3 and keep away from runner 2's one end and die cavity 4 intercommunication.

The cross section area ratio between two sections of pipelines of the fire inlet 3 is 1:0.6, and the joint between the two sections adopts arc transition, and the joint between the transverse runner 2 and the fire inlet 3 also adopts arc transition, so that the molten metal can smoothly and stably change the direction.

By shortening the length of the transverse pouring channel 2, the transverse pouring channel can be directly placed into a furnace, and smelting efficiency is improved; and the cross gate 2 is shortened, so that the flow velocity of the section of molten steel in the cross gate is improved, and the cold insulation proportion of products is reduced.

However, the flow velocity of the molten steel in the cross section of the transverse pouring gate is increased, so that the defect of the slag hole in the inner cavity is increased, the fire inlet 3 is designed into a step shape, and the slag blocking effect of the short pouring gate is improved by utilizing the step-shaped cross section decremental property.

The improved furnace return materials can be directly fed into the furnace; the stepped fire feeding design is utilized, so that the flow speed and slag blocking effect of molten steel are improved, the defects of cold insulation and slag holes are reduced, and molten iron is saved.
