Efficient wheel type casting machine and matched casting method thereof

Abstract

The invention provides an efficient wheel type casting machine and a matched casting method thereof, and relates to the technical field of metal casting. The efficient wheel type casting machine comprises a crystallization wheel (1), a steel belt (2), a conveying channel (3) and a pressing wheel, wherein the crystallization wheel (1) is provided with a concave crystallization wheel groove (4); the steel belt (2) is installed on a steel belt tensioning wheel (5), is tightened through a steel belt wheel (6) and bypasses the pressing wheel; a part of the crystallization wheel groove (4) is tightly attached to the steel belt (2) through the pressing wheel, so that a cavity extending in the circumferential direction of the crystallization wheel (1) is formed; a feeding port of the cavity is a sprue (8); an ingot extractor (9) for leading out cast ingots is arranged in the cavity; a wheel type channel (10) communicating with the cavity is arranged beside the ingot extractor (9); and a cast ingot traction device is arranged at the joint of the wheel type channel (10) and the conveying channel (3). According to the efficient wheel type casting machine and the matched casting method thereof provided by the invention, a current wheel type casting machine can be improved at low cost, so that the productivity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to a high-efficiency wheel casting machine and a matching casting method thereof. Background technique [0002] Currently commonly used wheel casting machines such as Patent No. CN200920037329.X disclose a casting machine for aluminum and aluminum alloy continuous casting and rolling production lines, including a machine base and a crystallization wheel. There is a transmission device, and there are cooling devices on the inside, outside, and left and right sides of the crystallization wheel. They are combined and installed on a cooling water distributor. The aluminum alloy wheel type horizontal casting machine is equipped with a horizontal combination pouring pot, and the horizontal position of the outlet end of the stainless steel spout is placed at the junction of the crystallization wheel cavity and the compression wheel, so that when the aluminum and aluminum alloy liquid...

Problems solved by technology

[0003] However, during the casting process, when the molten metal cools in the crystallization wheel and solidifies the crust to a certain thickness, due to the shrinkage of the billet shell, a gap (air gap) will be formed with the crystallization wheel and the steel strip, and its heat transfer resistance accounts for the total heat transfer resistance. 70%-80% of that, in this case the cooling efficiency drops significantly, which directly affects the productivity. In order to improve the productivity, most of the technical solutions of increasing the diameter of the crystallization wheel, increasing the cross-sectional area of ​​the ingot and increasing the roughing mill are adopted, but this not only It only increases the investment of equipment, but also increases the energy consumption, and the cost is higher
