Novel combined water cooling die

Abstract

The invention discloses a novel combined water cooling die. The novel combined water cooling die mainly comprises seamless steel pipes, side water ways, side water way sealing plates, a water inlet, awater outlet and a movable piece. The seamless steel pipes are linearly arranged in a flush manner from bottom to top and are welded into a whole. The two ends of the seamless steel pipes stretch into side water way cavities, and a rectangular frame is formed by the seamless steel pipes and the side water ways. The positions, making contact with the side water ways, of the seamless steel pipes are in full weld sealing. The side water ways are sealed and welded through the water way sealing plates. The water inlet and the water outlet are formed in the bottom end and the top end of each side water way sealing plate. Water partition plates are alternately welded in the two side water way cavities in the horizontal direction every 3-5 seamless steel pipes. The movable piece is detachably arranged at the bottom of the rectangular frame. A movable and replaceable template bottom plate is used, the damaged bottom plate is replaced, other parts can be continuously used, the maintaining efficiency is improved, and the die using cost is reduced.

Description

technical field [0001] The invention relates to a water-cooled mold, in particular to a water-cooled mold for cooling molten steel or alloy liquid in a vacuum melting furnace, an open melting furnace, and the like. It is widely used in the cooling and forming of various metal liquids such as hydrogen storage alloys, vanadium aluminum alloys, magnetic material alloys, and intermediate alloys, and can realize rapid cooling of high-temperature metal liquids. Background technique [0002] At present, vacuum melting furnaces, open melting furnaces and other casting molten steel or alloy liquid cooling molds generally use water-cooled discs, or sealed and fixed water-cooled molds. These two methods have poor thermal conductivity. On the low side. Therefore, prolonging the cooling time is usually used to achieve the required furnace temperature, and the production cycle of the equipment is relatively long. Usually, the bottom of the water-cooled mold is in contact with the alloy ...

AI Technical Summary

Problems solved by technology

Usually, the bottom of the water-cooled mold is in contact with the alloy liquid first, and the bottom of the mold is most likely to corrode. After the bottom of the mold is corroded, the entire mold must be scrapped.

Therefore, the existing water-cooled mold has long cooling time, low equipment production capacity, too much loose metal material, low product qualification rate, low mold service life, and increased maintenance costs.
