Technical Problem

[0005]本发明的目的在于提出一种装配式浇注流槽装置，用以解决现有浇注流槽在长时间使用时容易因受热不均导致浇注稳定性降低的技术问题

Benefits of technology

[0008] The beneficial effects of this invention are as follows: By setting a heat insulation layer between the refractory flow guiding component and the rigid support component, the heat transfer from the refractory flow guiding component to the rigid support component is isolated, preventing the rigid support component from bending and deforming due to uneven heating. This maintains the straightness of the entire casting channel device, thus solving the problem of external support structure deformation affecting casting stability. The refractory flow guiding component is made of refractory brick material, directly bearing the flow of molten metal. It has excellent high-temperature resistance and is not easily deformed under repeated hot and cold cycles, maintaining a stable channel shape for a long time and ensuring smooth molten metal flow. The fixing and clamping component is detachably connected to the upper part of the rigid support component, pressing downward against the upper edge of the channel brick. This stably fixes each section of the channel brick within the rigid support component, resisting the impact of molten metal and preventing the channel brick from shifting or misaligning, ensuring a continuous and smooth flow channel. The invention adopts a prefabricated layout, with each part detachable and combinable, making assembly convenient.

Abstract

The present application belongs to the technical field of centrifugal casting ductile iron pipe, and relates to an assembled pouring runner device, which comprises, from outside to inside, a rigid support assembly, a heat insulation layer and a refractory flow guide assembly; the rigid support assembly has a mounting groove extending longitudinally inside, and the heat insulation layer is laid on the inner wall of the mounting groove; the refractory flow guide assembly is made of refractory bricks and is mounted on the heat insulation layer, and comprises multiple flow runner bricks arranged longitudinally in sequence, and the flow runner bricks are provided with flow channels for metal liquid flow; a fixed and compressed assembly is detachably connected to the upper part of the rigid support assembly, and the fixed and compressed assembly downwardly presses the upper edges of the flow runner bricks to fix the flow runner bricks. The present application can effectively insulate heat to avoid the deformation of the support structure due to heat, thereby maintaining the straightness of the flow channels, improving the pouring stability, and ensuring the pouring quality.
