Nodular cast iron cooling device

Abstract

The invention discloses a nodular cast iron cooling device, and belongs to the technical field of iron castings. Through the device, the problems that nodular cast iron is difficult to salvage duringcooling, and the cooling effect is reduced due to continuous temperature rise of cooling water are solved. According to key technical points, the device comprises a cooling water tank, a water spraying table, a bearing table and a circulating water pipe, wherein a cooling water trough is formed in the cooling water tank, the bearing table is arranged in the cooling water trough, a lifting mechanism is installed at the bottom of the bearing table, the water spraying table is arranged on the inner wall of the upper portion of the cooling water tank, and a plurality of water spraying holes are formed in the inner side face of the water spraying table. According to the device, the liftable bearing table is arranged in the cooling water tank, the water spraying table is arranged on the inner wall of the upper portion of the cooling water tank, the circulating water pipe communicates with the cooling water trough, therefore, taking and placing of nodular cast iron are facilitated, and a scald caused by splashing of hot water generated when the nodular cast iron is directly put into water or a hot steam scald is avoided; and moreover, cooling water cyclically flows and is sprayed, so thatcontinuous rising of the water temperature in the cooling water trough is avoided, continuous cooling is realized, and the cooling effect is obvious.

Description

technical field [0001] The invention relates to the technical field of iron castings, in particular to a device for cooling ductile iron. Background technique [0002] Articles cast with molten iron are collectively called iron castings. Due to various factors, defects such as pores, pinholes, slag inclusions, cracks, and pits often appear. Due to various factors, iron castings often have defects such as pores, pinholes, slag inclusions, cracks, and pits. The commonly used repairing equipment is argon arc welding machine, resistance welding machine, cold welding machine, etc., and the cast iron parts need to be cooled after casting. [0003] The following problems exist in the existing cooling water tank technology for cast iron parts: 1. The water in the existing cooling water tank for cast iron parts is stagnant water, which cannot be cycled and replaced in the cooling water tank, and the cooling effect is poor. With the continuous cooling of nodular cast iron, The tempe...

Problems solved by technology

[0003] The following problems exist in the existing cooling water tank technology for iron castings: 1. The water in the cooling water tank for existing iron castings is stagnant water, which cannot be cycled and replaced in the cooling water tank, and the cooling effect is poor. With the continuous cooling of nodular cast iron, The temperature of the water in the cooling water tank continues to rise, reducing the cooling effect; 2. The existing rapid cooling water tank for cast iron parts has a complicated structure and is inconvenient to use. When cooling, the ductile cast iron is usually directly put into the cold water tank, which is not conducive to It is difficult to pick and place cast iron, and when putting it in, it is easy to cause hot water to splash or steam to escape, causing burns
