Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chain casting production, in particular to a molten alloy casting equipment. BACKGROUND

[0002] At present, in the steel smelting process, the alloy formed by remelting metal aluminum or aluminum-iron is usually used for component adjustment, deoxidation or production of steel finished products. The continuous casting unit is widely used in molten casting production due to its fast casting speed, strong production capacity, high automation degree and other advantages.

[0003] In production, the molten liquid flows out from the mixing furnace, flows into the boat-shaped ladle through the flow channel, and then is injected into the horizontally running casting mold. During the casting process, the flow of the aluminum liquid in the flow channel needs to be accurately adjusted according to the depth of the aluminum liquid in the casting mold. If the flow of the aluminum liquid is not reasonably controlled, it will seriously affect the appearance quality of the product, among which the surface water ripples have the greatest impact on the appearance quality of the finished product.

[0004] There are two reasons for the generation of water ripples. One is the stability of the conveying chain speed of the continuous casting machine. This type of water ripple has the greatest impact on the appearance quality of the finished product, and the ripple amplitude is the largest. Chain transmission is a flexible transmission. Due to its inherent non-uniformity of movement, i.e. the polygon effect of chain transmission, it will cause instability of the conveying chain of the casting machine during movement, thereby affecting the surface quality of the lead ingot. A large number of existing studies set auxiliary devices and conduct research on transmission to reduce the vibration of the conveying chain during work and the stability of the conveying chain speed of the continuous casting machine. The other reason is the alignment error during equipment operation. The upper surface of the molten liquid is naturally cooled in the air during the casting process, and the other surfaces are indirectly water-cooled through the casting mold. Therefore, the cooling of the aluminum ingot is gradually completed from the bottom to the upper surface. Therefore, the distributor and the casting mold need to be accurately aligned to accurately control the casting position and the casting flow, so as to ensure the best cooling and forming process and inhibit the generation of water ripples. However, in actual production, precision errors exist in the chain wheel, chain, guide rail and the like during manufacturing and installation, and control errors also exist during continuous transmission, which are unavoidable. Therefore, there is an uncertain alignment deviation between the outlet of the distributor and the casting mold. Based on this technical background, the present application designs a molten alloy casting equipment. SUMMARY

[0005] In order to solve the technical problem of the uncertain alignment deviation between the outlet of the distributor and the casting mold leading to the generation of water ripples in the prior art, the present application provides a molten alloy casting equipment. By setting a self-adaptive distributor, the outlet of the distributor is accurately aligned with the casting mold to accurately control the casting position.
