Temperature type casting method

Abstract

The invention provides a temperature type casting method. The temperature type casting method is characterized by comprising the steps that a casting mold is heated through a heater, or heat conducted by metal melt before the metal melt enters the casting mold is used for heating the casting mold, and the temperature of the casting mold is kept within the range of the temperature which is lower than the metal solidus temperature and higher than cooled casting mold temperature; metal is subjected to forced cooling through a cooler arranged near a casting mold outlet; and a metal casting blank is drawn through a pulling mechanism. The method is wide in application range and has great popularization value, the high-quality metal casting blank which is excellent in performance, good in surface smoothness, high in size precision, high in compactness and even in component and has a microstructure with columnar crystals, parallel or almost parallel to the blank drawing direction, in the metal and isometric crystals on the metal surface coexisting can be efficiently produced with low energy consumption, and subsequent heavy-reduction-rate plastic processing can be conducted as required.

Description

technical field [0001] The invention belongs to the technical field of metal casting, and in particular provides a warm mold casting method. Background technique [0002] Casting plays a pivotal role in the production of metals. With the continuous increase of metal materials and product varieties, the rapid expansion of application fields, the rapid development of high-tech and the improvement of people's living standards, the world is facing the current situation of environmental degradation, resource and energy shortages, and the energy saving of metal casting process The requirements for consumption reduction, short process, high efficiency, low cost and slab quality are getting higher and higher. [0003] The casting mold is a container for turning liquid metal into solid metal in casting and obtaining the required shape of the slab. It is the key component and "heart" in casting and plays an important role in the quality and output of the slab. At present, the molds ...

AI Technical Summary

Problems solved by technology

Since the temperature of the low-heat mold of warm mold casting is lower than the temperature of the heated mold and the two-phase zone mold, but higher than the temperature of the cooled mold, it can solve the problems produced by traditional continuous casting, semi-continuous casting and semi-solid casting methods. The surface finish, quality and performance of the slab are poor, the hot continuous casting method has low production efficiency and high energy consumption, it is difficult to produce a large cross-section slab, and it is easy to leak. The directional solidification method has low production efficiency and high energy consumption. The length is limited, the output is low, the energy consumption of the two-phase zone casting method is high, the casting speed cannot be too fast, and the semi-solid casting and two-phase zone casting methods cannot be used for the preparation of pure metals and eutectic alloys, etc.
