Upper-drawing casting device for the silicon bronze bar blank

Abstract

The invention discloses an up-drawing casting device for silicon bronze bar billet, comprising a smelter positioned on the landing control device. A side face of the smelter is provided with a power frequency furnace with an iron core, the upper surface of the power frequency furnace with an iron core is provided with a plurality of drawing devices which are positioned on a rolling crane. The drawing devices are provided with a crystallizer, the upper end of which is provided with a water inlet port and a water outlet port respectively. The dummy bars of the drawing devices are arranged through and in the crystallizer. The lower end of the crystallizer is provided with a graphite mould. The outside of the connection of the graphite mould and the crystallizer is provided with graphite protecting jacket. The invention has the advantages that the casting temperature of the up-drawing casting device for silicon bronze bar billet is low, the drawing speed is fast, the productivity effect is high, the grain of silicon bronze bar billet produced by the invention is uniformity and the production safety is good, thereby avoiding the dangerous accidents in operation.

Description

technical field [0001] The invention relates to a casting device for manufacturing a silicon bronze billet by using an upward-drawing method. Background technique [0002] The traditional casting of silicon bronze billet is cast by horizontal continuous casting device. This horizontal continuous casting device mainly includes melting furnace and holding furnace. The disadvantage is that the casting temperature is high, and the silicon bronze billet produced is due to Due to the different cooling conditions, the lower part of the billet has fine grains due to high cooling intensity, and the upper part has coarse grains due to low cooling intensity, which makes the grain structure of the produced silicon bronze billet uneven, affecting the quality of the product, and due to the level The number of traction devices on the continuous casting device is limited by the equipment conditions. Generally, only one or two can be installed, which makes the production efficiency of the de...

The disadvantage is that the casting temperature is high, and the silicon bronze billet produced is due to Due to the different cooling conditions, the lower part of the billet has fine grains due to high cooling intensity, and the upper part has coarse grains due to low cooling intensity, which makes the grain structure of the produced silicon bronze billet uneven, affecting the quality of the product, and due to the level The number of traction devices on the continuous casting device is limited by the equipment conditions. Generally, only one or two can be installed, which makes the production efficiency of the device low, and the phenomenon of pulling and leaking often occurs, which requires a high technical level of the operator. Dangerous accidents are prone to occur when ordinary workers operate
