Embodiment 1

[0033] A continuous manufacturing method for Φ16mm copper rod billet, first start the melting furnace 1, heat the furnace chamber 6 to 1200°C, start the screw 2 and adjust the speed to 20r / min, and connect the water inlet 10 and water outlet 11 of the crystallizer 3 Open it, let the cooling water start to flow, slowly add the pure copper particles with a composition of 99.99% from the feeding port 6, the added pure copper particles will melt rapidly and advance towards the crystallizer under the action of the screw, when the material is added to the screw When about three-quarters of the position, start the tractor 4, pull the pure copper rod billet 9 at a speed of 40mm / min, increase the rotating speed of the screw rod 2 to 100r / min at the same time, adjust the water inlet 10 in the crystallizer 3 size to make the towing process smooth. The pure copper pellets are replenished from the feeding port 6 in good time to realize the continuous production of high-quality pure copper ...

Embodiment 2

[0035] A continuous manufacturing method of Φ8mm aluminum alloy billets, first start the melting furnace 1, heat the furnace chamber 6 to 800°C, start the screw 2 and adjust the speed to 10r / min, and connect the water inlet 10 and the water outlet of the crystallizer 3 11 is opened to make the cooling water start to flow, and slowly add the aluminum alloy melt with the grade of 3003 from the feeding port 6, and the added aluminum alloy melt is pushed towards the crystallizer under the action of the screw, when the material is added to the four corners of the screw When the position is about three-thirds, start the tractor 4 to pull the aluminum alloy rod blank 9 at a speed of 200mm / min, and increase the speed of the screw 2 to 500r / min at the same time, adjust the size of the water inlet 10 in the crystallizer 3, Make the towing process smooth. The 3003 aluminum alloy melt is replenished from the feeding port 6 in good time to realize the continuous production of high-quality ...

Embodiment 3

[0037] A continuous manufacturing method of Φ60×3mm brass tube billet, first start the melting furnace 1, heat the furnace chamber 6 to 1050°C, start the screw 2 and adjust the speed to 20r / min, and connect the water inlet 10 of the crystallizer 3 and Open the water outlet 11 to make the cooling water start to flow, slowly add the brass particles with the brand name H65 from the feeding port 6, and the added brass particles will be melted quickly and pushed towards the crystallizer under the action of the screw, when the material is added When the three-quarters position of the screw rod is reached, the tractor 4 is started, and the pure copper rod billet 9 is pulled at a speed of 20mm / min, and the rotating speed of the screw rod 2 is increased to 100r / min at the same time, and the water inlet 10 in the crystallizer 3 is adjusted. The size makes the traction process smooth. Replenish the brass pellets from the feeding port 6 in good time to realize the continuous production of...

Abstract

The invention discloses a metal casting blank continuous manufacturing device capable of providing the pressure casting function. The device comprises a hollow melting furnace. A hollow furnace cavity is formed in the melting furnace. A feeding port is formed in the side wall of the furnace cavity. A threaded rod is arranged in the furnace cavity. One end of the threaded rod extends out of the furnace cavity. A crystallizer communicated with the furnace cavity is connected into the lower end of the furnace cavity. A water outlet and a water inlet are sequentially formed in the side wall of the crystallizer from bottom to top. The crystallizer is used for cooling metal casting blanks. A dragger used for dragging the metal casting blanks is further arranged below the crystallizer. The invention further provides a metal casting blank continuous manufacturing method. Through the device and method, the problems that metal casting blanks are loose, uneven in components, large in grain and poor in quality in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of metal casting slabs, and in particular relates to a continuous manufacturing device for metal casting slabs that can provide pressure casting, and also relates to a continuous manufacturing method for metal casting slabs. Background technique [0002] The processing and forming of metal often needs to melt the metal first to make an ingot, and then carry out plastic molding such as rolling, extrusion, and stretching on the ingot. The quality of the ingot plays a key role in the formability of the metal and the performance of the formed metal, such as composition uniformity, density, grain size, surface quality, etc. Existing production methods of metal ingots include vertical continuous (or semi-continuous) ingot casting, horizontal continuous ingot casting, upward continuous ingot casting, continuous casting and rolling, etc., all of which are atmospheric pressure ingot casting. Most metals solidify fro...
