A method of manufacturing a pipe embedded in the mold

The present invention describes a method for manufacturing a mold, for an arrangement can be used to manufacture steel inside the mold. The method involves manufacturing technology both line and casting process. Wherein the conduit manufacturing techniques comprising: a steel material, size selection; branch pipe connection method and the manifold; treated steel surface; positioning the support pipe sand tank. Casting techniques comprising: a flask runner design, steel casting temperature, casting speed and the like. According to the present invention can improve the positional accuracy of the filler pipe within the mold, and to avoid melt-through pipe, defects such as collapse.
