Abstract
The utility model relates to a centrifugal casting machine, comprising an electric motor (1), a driving shaft (2), an end cover (3), a pin (4), a casting mould (5), a supporting wheel (6) and a casting flow groove (8). The utility model is characterized in that the outer upper part of the casting mould (5) of the centrifugal casting machine is provided with an electromagnetic field generating device (9), and the casting mould is driven to rotate in the electromagnetic field by the supporting wheel driven by the electric motor.
Description
The utility model relates to a kind of centrifugal casting machine, particularly makes the centrifugal casting machine of high-quality spun cast pipe.
Casting alloy fills type in the model of rotation at a high speed and cooled and solidified becomes the process of pipe fitting to be referred to as centrifugal casting technique, and used relevant device is called centrifugal casting machine.The centrifugal casting machine of existing several main kinds is divided into according to the requirement of the characteristics of the technology pipe different with the production size, tube class foundry goods: vertical centrifugal-casting machine, horizontal centrifugal casting machine; Cantilevered centrifugal casting machine and drum-type centrifugal casting machine are arranged again in horizontal centrifugal casting machine, the common trait of these several centrifugal casting machines is: be made up of power transmission and pipe die and casting system, be mainly used in and produce tubing, tube class foundry goods, its advantage is just to produce without core foundry goods, tubeization sleeve, the tubing foundry goods of hollow.Founding materials is widely applicable, foundry goods dense structure, and pore, shrinkage cavity, defective such as to be mingled with less; Its deficiency is that centrifugal casting technique can not effectively be controlled the foundry goods tissue, and for some alloy, macrostructure is thick column crystal on the section usually, because crystal grain is thick and directionality is arranged, causes that the performance of foundry goods descends, and intensity and toughness are all relatively poor; Secondly foundry goods easily produces gross segregation, influence the performance of foundry goods, in the time of seriously even cause product rejection.Because these deficiencies are difficult to realize that especially high-alloy steel is all the more so, has limited the scope of application for the higher foundry goods of some performance requirements.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art.
The purpose of this utility model is to provide a kind of new centrifugal casting machine, has other power to put on liquid metal when liquid metal is solidified in centrifugal casting machine, makes its solidified structure become tiny and uniform tissue, reaches the purpose that improves performance.
The purpose of this utility model is achieved through the following technical solutions:
A kind of centrifugal casting machine, comprise motor (1), power transmission shaft (2), end cap (3), pin (4), casting mold (5), support roller (6), roller frame (7), casting chute (8), on it is characterized in that outside the casting mold (5) at centrifugal casting machine electromagnetic field generator (9) has been installed, casting mold is rotated in electromagnetic field by the support roller drive of electric-motor drive.
The utlity model has following advantage:
Because the utility model has been installed electromagnetic field generator on centrifugal casting machine, model and liquid cast alloy are passed in the magnetic field that magnetic pole produced, therefore, when liquid cast alloy and the rotation of model one superhigh speed, liquid cast alloy itself produces induced current, the liquid cast alloy will be subjected to the electromagnetic force opposite with the direction of motion simultaneously, the effect of this electromagnetic force makes the temperature field of liquid cast alloy in process of setting, solute Distribution, machinery is rotten all significantly different with original centrifugal casting, therefore very big variation has taken place in the process of setting of electromagnetic centrifugal foundry goods, the macroscopic view of electromagnetic centrifugal cast tube, the microstructure refinement, new characteristics have appearred in solute Distribution, the combination property of cast tube is than improving greatly originally, and magnetic field intensity is different with the rotating speed of centrifuge, influence for the tissue of cast tube is also different, thereby realized within the specific limits the effective control to casting quality.For example: the test pipe fitting with the HK40 steel is an example, the performance of electromagnetic centrifugal foundry goods is improved than the performance of common centrifugal casting comprehensively, intensity, yield strength and plasticity index in room temperature and the high temperature, short time mechanical property all obviously increase, high temperature endurance performance significantly improves, can improve 80% creep rupture life at most, and rupture ductility can improve 2-4 doubly.
The groundwork mode of electromagnetic centrifugal casting machine and the maximum of common centrifugal casting machine are not both: common centrifugal casting is in process of setting under the action of centrifugal force, and the foundry goods of electromagnetic centrifugal casting machine is when being subjected to centrifugal force, in process of setting, also be subjected to the influence of electromagnetic force, and along with the changes in process parameters of electromagnetic system, the function that the common especially centrifugal casting machine of this point is not realized.

The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of centrifugal casting machine, comprise motor (1), power transmission shaft (2), end cap (3), pin (4), casting mold (5), support roller (6), roller frame (7), casting chute (8), on it is characterized in that outside the casting mold (5) at centrifugal casting machine electromagnetic field generator (9) has been installed, casting mold is rotated in electromagnetic field by the support roller drive of electric-motor drive.
Electromagnetic field generator of the present utility model, model and liquid cast alloy are passed in the magnetic field that magnetic pole is produced, when liquid cast alloy and the rotation of model one superhigh speed, liquid cast alloy itself produces induced current, the liquid cast alloy will be subjected to the electromagnetic force opposite with the direction of motion simultaneously, and as shown in Figure 1: the liquid cast alloy moves to different parts in model all can be subjected to centrifugal force f
