Embodiment 1

[0041] Such as figure 1 and figure 2 As shown, a circular ingot casting equipment is used for casting a large cylindrical ingot, which mainly includes a gating system 100 , a rolling system 200 , a casting mold 300 and a support column 400 . Wherein, the support column 400 is arranged vertically, and its bottom end is fixedly connected on the ground or corresponding equipment; the pouring system 100 is used for injecting the melt into the casting mold 300, and the casting mold 300 is used for forming the ingot; the rolling system 300 is used for When the melt solidifies into a casting, the upper end of the ingot is flattened and rolled. The specific structure and working principle of the device will be described in detail below.

[0042] Such as Figure 6 As shown, a section of the middle part of the support column 400 has a thread for the installation of the casting mold 300. The upper and lower ends of the thread have a certain distance from the upper and lower ends of the...

Embodiment 2

[0049] A kind of annular ingot casting method, adopts a kind of annular ingot casting equipment of embodiment 1, and its steps are:

[0050] 1. Before starting casting, adjust the height of the casting mold 300 on the support column 400 so that the bottom of the casting mold 300 is close to the bottom of the roll 210 and the flow distributor 130 but maintain a small gap, which is 6 mm in this embodiment. After adjustment, the casting system 100 works to add melt to the tundish, and the melt spreads evenly in the mold cavity 330 through the shroud and flow distributor 130, and is cooled and solidified in the mold cavity 330 to form a casting with a certain height. At the same time, the casting mold 300 is driven to rotate by the rotating device, and is lifted and lowered on the supporting column 400 under the thread cooperation between the supporting column 400 and the inner ring of the casting mold 300 . The rollers 210 of the rolling system 200 level the melt that has not bee...

Abstract

The invention discloses annular ingot casting equipment and a casting method thereof, and belongs to the field of metallurgical casting. The annular ingot casting equipment comprises a pouring system,a rolling system, a casting mold and a supporting column; the casting mold comprises an inner ring and an outer ring, and a mold cavity is formed between the inner ring and the outer ring; the supporting column penetrates through the inner ring and is in threaded connection with the inner ring; the pouring system is fixedly arranged on the upper part of the supporting column and injects melt intothe mold cavity; and the rolling system is fixedly arranged on the supporting column and comprises rollers which are horizontally arranged in the mold cavity. Various defects during preparation of alarge annular ingot can be effectively reduced, the uniformity of the structural components of the ingot is increased, and therefore the mechanical performance of the ingot is improved. By adopting the annular ingot casting equipment in the casting method, the large annular ingot is prepared through continuous melt laying and rolling leveling methods, the large annular ingot can be quickly prepared through the method, and the prepared ingot has excellent mechanical properties.

Description

technical field [0001] The invention belongs to the field of metallurgical casting, and more specifically relates to an ingot casting equipment and a casting method thereof. Background technique [0002] The manufacturing method commonly used in foundry metallurgical production, it is the manufacturing process of pouring the smelted metal liquid into the mold, cooling and solidifying to obtain the parts with the required shape and performance. Casting manufacturing costs are low, the process is flexible, and complex shapes and large billets can be obtained. It occupies a large proportion in machinery manufacturing. For example, 60-80% of the parts in the machine tool industry are made by casting, and 60-80% in the automotive industry. The parts are made by casting. [0003] In casting, the casting process, the microstructure, structure and performance of the slab will have an important or even decisive impact on the subsequent processing and the quality of the final product...
