Embodiment 1

[0016] The casting method of the metal composite liner in this embodiment includes the following steps:

[0017] A. Inject the first metal liquid into the mold formed by the lower mold and the upper mold of the first metal layer, and remove the upper mold of the first metal layer under the high temperature state after the first metal layer is solidified;

[0018] B. Clamp the second metal layer upper mold and the lower mold, and vacuumize the mold. When the vacuum degree in the cavity of the first metal layer and the second metal layer upper mold is 0.04MPa, keep it for 20s, and then apply Pouring into the cavity to pour the second molten metal, the pouring temperature of the second molten metal is higher than the pouring temperature of the first molten metal;

[0019] C. After the pouring is completed, apply ultrasonic vibration for 23s. The ultrasonic vibration frequency is 20KHz. The second molten metal is solidified and cooled to form a metallurgical bond with the first me...

Embodiment 2

[0021] The casting method of the metal composite liner in this embodiment includes the following steps:

[0022] A. Inject the first metal liquid into the mold formed by the lower mold and the upper mold of the first metal layer, and remove the upper mold of the first metal layer under the high temperature state after the first metal layer is solidified;

[0023] B. Clamp the upper mold and the lower mold of the second metal layer, and vacuumize the mold. When the vacuum degree in the cavity of the upper mold of the first metal layer and the second metal layer is 0.05MPa, keep it for 25s, and then apply Pouring into the cavity to pour the second molten metal, the pouring temperature of the second molten metal is higher than the pouring temperature of the first molten metal;

[0024] C. After the pouring is completed, apply ultrasonic vibration for 26s. The frequency of ultrasonic vibration is 19.3KHz. The second liquid metal is solidified and cooled, forming a metallurgical bo...

Embodiment 3

[0026] The casting method of the metal composite liner in this embodiment includes the following steps:

[0027] A. Inject the first metal liquid into the mold formed by the lower mold and the upper mold of the first metal layer, and remove the upper mold of the first metal layer under the high temperature state after the first metal layer is solidified;

[0028] B. Clamp the second metal layer upper mold and the lower mold, and vacuumize the mold. When the vacuum degree in the cavity of the first metal layer and the second metal layer upper mold is 0.06MPa, keep it for 30s, and then apply Pouring into the cavity to pour the second molten metal, the pouring temperature of the second molten metal is higher than the pouring temperature of the first molten metal;

[0029] C. After the pouring is completed, apply ultrasonic vibration for 29s, and the ultrasonic vibration frequency is 19KHz. The second molten metal is solidified and cooled to form a metallurgical bond with the firs...

Abstract

The invention discloses a casting method of a metal composite lining plate, and relates to the technical field of casting. The method comprises the following steps: a first molten metal is injected into a casting mold which is formed by closing a lower mold and an upper mold of a first metal layer, and the upper mold of the first metal layer is removed under the high-temperature state after the first metal layer is solidified; an upper mold of a second metal layer and the lower mold are subjected to mold closing, a mold is vacuumed, and then a second molten metal is poured into a mold cavity; after pouring is completed, the ultrasonic vibration is applied for 23-29 seconds, the second molten metal is solidified and cooled, and a metallurgical bonding state is achieved between the second molten metal and the first molten metal. According to the casting method of the metal composite lining plate, the problem that a clear binding interface cannot be formed due to the fact that a mixing phenomenon is prone to occur during casting the existing metal composite lining plate.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting method of a metal composite liner. Background technique [0002] The metal composite liner is a layered composite plate formed by combining two metals through metallurgy, taking advantage of the advantages of the two metals, and achieving performance requirements that cannot be met by a single metal. The existing metal composite liner casting method is to successively pour two kinds of metal liquids into the same mold through two pouring systems at a certain pouring temperature, and obtain a composite liner after cooling and solidifying. This casting method has the following disadvantages: the time interval between the pouring of the two molten metals is not easy to control, and the mixing of the two metals is prone to occur in the bonding area, and a clear bonding interface cannot be formed. Contents of the invention [0003] The purpose of the present invention is ...
