Embodiment Construction

[0021] A direct-cooled chiller for casting gray iron castings and ductile iron castings, the material of which is ordinary carbon steel;

[0022] The outer surface of the direct cooling cold iron has an anti-drop groove structure, and its two ends are used as working surfaces, and a groove with a width of 15mm and an angle of 120° is opened in the middle of the cold iron;

[0023] The cross-section of the direct-cooled cold iron is circular, square or rectangular.

Abstract

The invention relates to a chiller for a casting process, and in particular relates to a direct cooling chiller for casting gray cast iron castings and ductile iron castings. The direct cooling chiller is characterized by being made of common carbon steel, and is also characterized in that an anti-falling clamping groove structure is arranged on the outer surface of the direct cooling chiller; two end surfaces of the direct cooling chiller are used as working surfaces; a groove with the width of 15mm and the angle of 120 degrees is formed in the middle of the chiller. The chiller is made of a unique material, the utilization rate of a steel chiller is improved, the service life of the chiller is prolonged, the risk cost loss, caused by repair and defect treatment, of a customer in the machining process is reduced, and the chiller is easy to machine and manufacture.

Description

technical field [0001] The invention relates to a chill iron used in the casting process, in particular to a direct cooling chill iron used for casting gray iron castings and ductile iron castings. Background technique [0002] The structure and internal quality of gray and nodular iron castings are designed according to the requirements of the castings, and the wall thickness is uneven, which leads to a large number of structural hot joint areas and thick and large cross-sectional areas on the castings. An important criterion for the intrinsic quality of castings is the compactness of the metal materials that make up the castings. There are many methods to ensure the compactness of metal materials in the casting process, such as: riser feeding, internal chilling of iron materials, external chilling and comprehensive strengthening of feeding and so on. These ways and methods belong to three different casting processes of natural state, internal force and external force resp...
