Structure for increasing riser feeding distance and provided with gas forming block at top of riser

Abstract

The invention is a structure that increases the feeding distance of the riser and arranges an air generating block on the top of the riser. When the common side riser is used to feed the inside of the volute, the purpose of feeding cannot be achieved due to the long distance between the riser neck and the feeding part. Now the top of the riser is provided with an air-generating block, and a thin steel plate is covered outside the air-generating block. After the gas generating block contacts the molten iron, it will generate heat and generate gas when heated, which can increase the fluidity of the riser molten iron and move to the feeding part. At the same time, the gas generating block is blocked by the thin steel plate to prevent the molten iron from being heated too quickly. The feeding effect of the riser is normal, and the casting can be effectively fed.

AI Technical Summary

Benefits of technology

This technology allows for efficient use of molasses during production while maintaining good flow properties through an immersion nozzle system used in roll castings. By melting outer layers off one side of each other at certain points along its length, it becomes more liquid-like before being forced downwardly towards another area where there are fewer parts needed. Additionally, if some areas have been damaged or worn out due to wear overtime, these cracks can be repaired quickly without causing any problems like leakage from the device's valve. Overall, this process helps improve efficiency and productivity in manufacturing processes.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving casting efficiency for engines with turbines that use multiple valves arranged along their length. Specifically, there can exist variations where different components within these systems require precise placement during manufacturing due to differences in temperature conditions when they melt down into liquid metal. These issues lead to difficulties in achieving efficient flow through various areas such as pipelines, manifolds, nozzles, etc., leading to reduced production rates and increased costs associated with maintenance work on those affected devices.
