Abstract

The invention discloses a V-method casting system for solving a pore problem by using an overflow riser. The V-method casting system comprises a pouring system and the overflow riser, the pouring system comprises at least two ingates, the overflow riser is arranged at the intersection of front-edge molten steel at the far end of a casting mold and is used for collecting the front-edge molten steelmixed with inclusions and gas, clean molten steel is kept in a casting body, and pore defects are avoided. Through directional design of a molten steel flow field in the V-method casting and pouringprocess, the overflow riser is arranged at the intersection of the front-edge molten steel at the far end of the casting mold, the front-edge molten steel mixed with inclusions and gas can be collected, the condition that clean molten steel is kept in the casting body is ensured, and the pore defects are avoided; and the condition that the front-edge molten steel mixed with the inclusions and gasthat are generated by the mold, a core, coating and a thin film in the pouring process can be collected in the overflow riser is ensured, and the condition that the molten steel is hermetically kept in a casting to generate pores is avoided. Pore defects of the V-method casting are greatly reduced, the product percent of pass is increased, the production efficiency is improved, and the practical value is high.

Description

technical field [0001] The invention relates to the technical field of V-method casting, in particular to a V-method casting system using an overflow riser to solve the problem of pores. Background technique [0002] Because of the scattered pouring system of the V-method casting process, the process of filling the mold with molten steel is long. Frontier molten steel has been exposed to the air during the filling process, fully contacted with air, forming a large number of oxidized inclusions; frontier molten steel has been in contact with the mold for a long time, and continues to undergo heat exchange reaction with low-temperature molding sand, and the temperature of molten steel drops rapidly , and its fluidity also decreases; the frontier molten steel flows through the coating layer and EVA film first, decomposing the organic matter and film in the coating, and the gas generated is easily drawn into the frontier molten steel. Therefore, at the intersection of the far e...
