Abstract

The invention provides a temperature-controlled metal casting method. The method includes the steps that firstly, molten metal in a crucible is stirred so as to be uniform in ingredient mixing and temperature distribution; secondly, the molten metal in the crucible flows into a homogenization device through a flow guide pipe; thirdly, the molten metal forms a homogenized turbulent flow under the effect of a spiral pipeline of the homogenization device, and the temperature of metal at an outlet of the homogenization device is lowered to below a solid phase line under the effect of a cooling pipeline; fourthly, the metal at the outlet of the homogenization device is continuously drawn into a metal casting blank under the effect of a drawing device. By means of the temperature-controlled metal casting method, a prepared metal casting is high in surface gloss, compact in internal structure, uniform in grain size, free of segregation and cracks and high in plasticity and quality; besides, energy is saved, the process is simplified, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to a temperature-controlled metal casting method. Background technique [0002] Metal casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a mold, cooled and solidified, and cleaned to obtain a casting with a predetermined shape, size and performance. It plays a pivotal role in the production of metals. With the continuous increase of metal materials and product varieties, the rapid expansion of application fields, the rapid development of high-tech and the improvement of people's living standards, the world is facing the current situation of environmental degradation, resource and energy shortages, and the energy saving of metal casting process The requirements for consumption reduction, short process, high efficiency, low cost and slab quality are getting higher and higher. [0003] At present, the molds used in metal...
