Description

Large-size water-cooling metal casting section mechanism

Technical field

The utility model relates to ball mill with wear-resisting iron and steel medium casting section apparatus field, relates in particular to a kind of large-size water-cooling metal casting section mechanism.

Background technology

For many years, in the metallurgical industry, be used in and be used for the iron and steel meson casting ball of rubble ore grinding in the ball mill and be widely used always, because making it contact with ore, spherical profile is the some contact, in order to overcome the deficiency of casting ball, in recent years, the insider finds that a kind of to be shaped as the rubble grinding efficiency of cylindrical casting section in ball mill better, and the mould of metal current type casting section mostly is that die body is less, generally is no more than 700 * 1000 millimeters, be artificial rotation, the inner chamber of die body has only the cooling water of half capacity, the first half is not in the water-cooled scope, therefore after the molten iron of casting is poured in the matrix model on the die body outer surface, die body upper temp wink liter, in case forward the bottom to, temperature decrease behind the chance water causes the die body material crack easily, reduced die life, because the casting section cooling velocity after the casting is slow, cool time is short simultaneously, casting section calcining temperature height, cause the crystal grain of casting intersegmental part metallographic structure thick, hardness is not high.

During traditional casting section was produced, normally hand end ladle was with in the molten iron injection model for the workman, and labour intensity is big, the environment temperature height, and production efficiency is very low.Owing to cast being in great demand of section in the metallurgy industry, increase output and have only, so floor space be very big by increase equipment.

The utility model content

The purpose of this utility model provides a kind of good product quality that casts out, hardness height, and device structure is simple, and is easy to operate, a kind of large-size water-cooling metal casting section mechanism of high efficiency.

The purpose of this utility model is to realize in the following manner:

Large-size water-cooling metal casting section mechanism of the present utility model, comprise die body, the bearing that is rotationally connected with the die body rotating shaft, water inlet pipe that is communicated with the die body inner chamber and outlet pipe and casting ladle, it is characterized in that: described die body is made up of with the hollow rotating shaft I and the hollow rotating shaft II of fixedlying connected with model cylindrical shell end respectively the model cylindrical shell that has cavity, described hollow rotating shaft I is connected with drive unit, the outlet pipe that is located at the water inlet pipe in the hollow rotating shaft I hole and is located in the hollow rotating shaft II hole is communicated with the die body inner chamber respectively, the water inlet termination of described outlet pipe is positioned at the top of die body inner chamber, the casting ladle is mounted on the suspension hook that is flexible coupling that is positioned at the die body top, is provided with the insulation kiln below die body.

Described die body diameter is 800-1600mm, length is 1200-6000mm.

Described outlet pipe is a bend pipe structure, and the horizontal component of bend pipe is connected with cooling bay, and water inlet termination and die body cavity inner surface are apart from 10-30mm.

Described drive unit adopts the electrodeless variable-speed motor.

The utility model has the advantages that: large-size water-cooling metal casting section mechanism of the present utility model is the equipment of the casting section used of ball mill, the diameter by strengthening die body and the height of the water inlet termination of length and raising outlet pipe, make the die body inner chamber have enough volumes to fill up cooling water, make die body be in the state of being cooled all the time, after molten iron is poured in the model one by one of die body, be cooled immediately, this cooling procedure, play the effect of crystal grain thinning, surpassed the heat treated casting section of process of legacy equipment output through its metallographic degree of grain refinement of instrument detecting.Simultaneously, this process that the casting section is cooled off is rapidly also impelled the model disengaging automatically smoothly of casting section and die body.

The weight that the suspension hook that the utility model die body top is provided with is carrying cast ladle and molten iron has been broken away from the mode that traditional artificial load-carrying is cast, and has significantly reduced working strength of workers.The adjustment of the electrodeless variable-speed of drive unit, cooling water circulation rate can fully guarantee under the varying environment temperature product quality of casting section.
