Description

Bending type mandrel mechanism for crystallizer forming process

Technical Field

The utility model relates to a crystallizer shaping technology technical field specifically is a crooked type dabber mechanism for crystallizer shaping technology.

Background

The mold is a continuous casting apparatus that receives molten steel poured from a tundish and solidifies it into a solid shell having a predetermined cross-sectional shape. The casting blank is the most critical component of a continuous casting machine, and the structure, the material and the performance parameters of the casting blank play a decisive role in the quality of the casting blank and the production capacity of the casting machine. A grooved crystallizer is composed of a jacket on its wall or a coiled pipe in it for heating or cooling the solution in the groove. The crystallization tank may be used as an evaporative crystallizer or a cooling crystallizer. In order to improve the production strength of the crystal, a stirrer can be additionally arranged in the tank. The crystallization tank may be used for continuous operation or batch operation. The crystals obtained by intermittent operation are large, but the crystals are easy to be connected into crystal clusters and carry mother liquor, so that the purity of the product is influenced. The crystallizer has simple structure and low production strength, and is suitable for the production of small-batch products (such as chemical reagents, biochemical reagents and the like).

In order to prevent the molten steel from being bonded with the inner wall of the crystallizer in the condensation process, reduce the friction resistance in the blank drawing process, improve the surface quality of a casting blank and prolong the service life of the crystallizer, the inner wall of the crystallizer needs to be lubricated in the production process. The lubrication is to adopt liquid lubricant or protective slag with the boiling point higher than the temperature of the inner wall of the crystallizer (about 200 ℃), the liquid lubricant or protective slag is continuously carried into the inner wall below the molten steel surface in the process of the vibration of the crystallizer, and a layer of oil-gas film or slag film is formed between the molten steel or blank shell and the inner wall of the crystallizer to lubricate the inner wall.

The mandrels adopted in the existing crystallizer are all straight and cannot be bent, and various requirements cannot be met.
