Abstract: An environment servo type clean metal casting mold has a casting mold body with an ingate. The casting mold body includes a cold bottom mold plate and a peripheral mold plate that is connected with the cold bottom plate. The peripheral mold plate is provided with a vertical temperature break servo device. The temperature of the vertical temperature abrupt servo device contacting with the cooling metal varies in the vertical direction, hence the liquid metal has rapid heat emission, crystallization and solidification.

Abstract: A clean metal ingot mold comprises an ingot mold body and an insulating riser arranged on the ingot mold body. The bottom mold plate of the ingot mold is provided with at least a ridge connected thereto. The region having a V-shape containing impurities produced during the crystallization process of the liquid metal moves upwards because of the ridge, and then the impurities depart from the center of the cast ingot and the impurities are more centralized. A water-cooling device is arranged in the ridge to allow the temperature of the metal in the ingot mold to decrease rapidly, and the crystallization process of the metal to be rapid.

Abstract: A non-electroslag remelting type clean metal ingot mold includes an ingot mold body and a insulating riser arranged on the ingot mold body; an insulated heating and heat preservation device is vertically arranged in the ingot mold body and divides the space in the ingot mold body into a plurality of independent cavity units; and the cavity units are distributed in two rows in the ingot mold body. Because the insulated heating and heat preservation device is arranged in the ingot mold body and divides the space in the ingot mold body into a plurality of independent cavity units, most of impurities and segregates in liquid metals are enriched in the part in contact with the isolation and heat insulation mechanism during the directional solidification and crystallization of the liquid metals and the enriched alloy segregates, and the impurities can be easily eliminated by utilizing flame or other processing methods.
