Abstract

The invention aims at the defects of complex manufacturing process and large energy consumption for producing plates by using the pouring die and the production method in the prior art and provides a production method of corrosion resistant alloy plates and a split type pouring die used by the same. A die body is composed of a half square cylinder-shaped female die and a half square cylinder-shaped male die, the female die and the male die are combined to form a square cylinder-shaped die cavity by a female die matching surface and a male die matching surface, and the female die and the male die are fastened into a whole by a fastening device. The production method comprises the following steps of: carrying out vacuum pouring to obtain a rough plate blank by adopting the split type pouring die, removing oxide skins and feed heads for the rough plate blank to obtain a plate blank, and rolling the plate blank to obtain the plate. According to the split type pouring die and the production method, because the shape of an inner cavity of the die body is in consistent with the plate blank shape required by the plate, the rough plate blank formed by pouring can become the required plate blank so long as the oxide skins and the feed head are removed, the forging process is saved, and the processing cost is reduced by 20%.

Description

technical field [0001] The invention relates to a production method of a plate and a casting mould used, in particular to a production method of a corrosion-resistant alloy plate with a high aspect ratio and a split casting mould used. Background technique [0002] At present, the mold used for ingot casting consists of a mold body, a chassis and a heat preservation cap. The mold body has an integrated structure. In order to facilitate the removal of the ingot from the mold, the inner cavity of the mold body is set to a certain taper in the height direction. . Since in the molten steel casting process, mold sticking often occurs, that is, the steel ingot and the mold are connected together. When the mold with the above structure is used to cast the ingot, since the mold body is integral, it is necessary to force the ingot from the overall structure. Take it out from the inner cavity of the mold body. Therefore, it is necessary to use gravity to hammer the ingot, or use ext...
