Casting technology with the formation of a uniform fine-grained metal structure

Abstract

The paper is devoted to the development of vacuum casting technology, which ensures the formation of a casting with a uniform fine-grained metal structure. This effect is achieved by the slow filling of the cooled cavity of the mold with a cooling liquid due to the difference in the flow rate of the liquid at the inlet and outlet. At each moment of time, the cooling of metal is carried out in a thin layer of the casting, which ensures the uniformity and fine-grained structure of the casting material, the absence of shrinkage and internal stresses.

Design of Hydraulic Master Integrated Valve Body Pouring Device for Excavator and its Application Method

“…By reducing energy consumption and waste generation, the integrated valve body placement device helps reduce the consumption of natural resources and reduces environmental pollution [9] . In summary, The pouring process has a huge impact on product quality [10] , and the excavator hydraulic master integrated valve body pouring device is the construction machinery industry's demand for improving efficiency, reducing risk, energy saving [11] and environmental protection, as well as the continuous innovation and development of hydraulic control technology [12] . Through the design of a new excavator hydraulic master integrated valve body pouring device, by setting the connecting plate, movable plate, sealing plug, push plate, spring, push column, receiving frame and fixed plate, using the motor to drive the rotation of the rotating plate, the height of the treatment box is adjusted, and then improve the quality of the pouring, bringing more efficient, reliable and sustainable construction solutions for the construction machinery industry.…”
