Large-size water-cooling metal casting section mechanism

Abstract

The invention relates to the field of casting section equipment of wear resistant media for ball mills, in particular to a large-size water-cooling metal casting section mechanism which comprises a die body, a supporting seat which is connected with rotating shafts of the die body in a rotating way, a water inlet pipe and a water outlet pipe which are communicated with an inner cavity of the die body, and a hanging hook of a casting ladle. The invention is characterized in that the die body comprises a die cylinder with a hollow cavity, as well as a hollow rotating shaft I and a hollow rotating shaft II which are respectively connected with the end part of the die cylinder fixedly; the hollow rotating shaft I is connected with a driving device; the water inlet pipe arranged in a hole of the hollow rotating shaft I and the water outlet pipe arranged in a hole of the hollow rotating shaft II are respectively communicated with the inner cavity of the die body; the water outlet pipe is ina bent pipe structure; the water inlet end is positioned at the upper part of the inner cavity of the die body; the casing ladle is hung on the hanging hook of flexible connection above the die body;a heat insulating kiln is arranged below the die body; and the driving device uses an infinite variable speed motor. The invention has the advantages of time saving, labor saving and high product hardness, and the working efficiency is increased by 60%.

Description

technical field [0001] The invention relates to the field of wear-resistant iron and steel medium casting section equipment for ball mills, in particular to a large water-cooled metal casting section mechanism. Background technique [0002] For many years, in the metallurgical industry, steel meson casting balls used in ball mills for crushing ore grinding have been widely used. Due to the spherical shape, the contact with the ore is point contact. In order to overcome the shortage of casting balls, in recent years, People in the industry have found that a cylindrical casting section has a better crushing effect in a ball mill, but most of the molds for metal casting sections currently have a smaller mold body, generally no more than 700×1000 mm, it is manually rotated, the inner cavity of the mold body only has half the capacity of cooling water, and the upper part is not within the water cooling range, so when the molten iron is poured into the concave mold on the outer s...

[0002] For many years, in the metallurgical industry, steel meson casting balls used in ball mills for crushing ore grinding have been widely used. Due to the spherical shape, the contact with the ore is point contact. In order to overcome the shortage of casting balls, in recent years, People in the industry have found that a cylindrical casting section has a better crushing effect in a ball mill, but most of the molds for metal casting sections currently have a smaller mold body, generally no more than 700×1000 mm, it is manually rotated, the inner cavity of the mold body only has half the capacity of cooling water, and the upper part is not within the water cooling range, so when the molten iron is poured into the concave mold on the outer surface of the mold body, the temperature of the upper part of the mold body will be instantaneous. Once it turns to the lower part, the temperature will drop suddenly after encountering water, which will easily cause cracks in the mold body material and reduce the service life of the mold. The grains of the metallographic structure inside the casting section are coarse and the hardness is not high

[0003] In traditional casting section production, workers usually inject molten iron into the mold with ladles in their hands, which is labor intensive, high ambient temperature, and low production efficiency.

Due to the large demand for casting sections in the metallurgical industry, the only way to increase production is to increase equipment, so it occupies a large area
