Embodiment Construction
[0027] In the prior art, due to the different specifications of the crystallizers, it is necessary to process dummy heads of different sizes according to the crystallizers of different diameters, so as to match them. However, the mechanical processing process of the integral dummy head is complicated, the processing cycle is long, and the manufacturing cost is high.
[0028] In order to solve the technical problem, the present invention provides a method for manufacturing a dummy head, the dummy head is used to seal the bottom of the crystallizer and matches with the bottom of the crystallizer, the crystallizer has a bottom diameter, comprising: providing A first component, the first component is a cylinder having a first diameter and a first thickness, the first component contains a first central hole through its thickness, the first central hole has a first diameter, the The first diameter is smaller than the bottom diameter of the crystallizer; a second assembly is provided...

Abstract
Disclosed is a manufacturing method of a dummy bar head. The dummy bar head is used for sealing the bottom of a crystallizer with a bottom diameter. The manufacturing method of the dummy bar head comprises the steps that a first assembly is provided, wherein the first assembly is provided with a first diameter and a first thickness, is cylindrical, and comprises a first center hole, the first center hole penetrates through the thickness of the first assembly and is provided with a first hole diameter, and the first diameter is smaller than the bottom diameter; a second assembly is provided, wherein the second assembly comprises a first cylinder and a second cylinder located on the top of the first cylinder, the first cylinder is provided with a second diameter, the second cylinder is provided with a third diameter and a third thickness, the third diameter is smaller than the first hole diameter, and the third thickness is equal to the first thickness; and the first center hole of the first assembly sleeves the second cylinder of the second assembly, and then the smelting technology is conducted. According to the manufacturing method of the dummy bar head, the first assembly is manufactured according to the size of the crystallizer, the first diameter can be matched with the bottom diameter of the crystallizer, and therefore the first assemblies with different diameters only need to be manufactured according to the bottom diameters of the crystallizers, the manufacturing process of the dummy bar head is simplified, the manufacturing period is shortened, and the manufacturing cost can also be reduced.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for manufacturing a dummy head. Background technique [0002] Casting process is an important link in modern industrial production. Among them, the dummy head is one of the important devices in the casting process. As the live bottom of the crystallizer, the joints of the crystallizer are tightly blocked to prevent the metal water from flowing out. After pouring, the metal water solidifies in the cavity formed by the dummy head and the crystallizer. [0003] However, the manufacturing process of the dummy head in the prior art is relatively complicated, and the manufacturing cost is relatively high. Contents of the invention [0004] The problem solved by the invention is to provide a dummy head manufacturing method, which simplifies the manufacturing process and reduces the manufacturing cost. [0005] In order to solve the above problems, the present invention ...
