Embodiment approach
[0008] For the above purpose, the following measures are taken, that is, vacuum protection is adopted throughout the whole process, including the addition of raw materials in the hot furnace, the melting and preparation of magnesium alloy materials, the buffering of the thermal insulation homogenization furnace to ensure that the melting operation and the continuous casting operation are synchronized in time, and the modification of liquid materials It works in a closed environment without external interference, and achieves the design goal of no pollution in the whole process. In addition, the raw materials used in the present invention do not refer to the master alloys and working alloys used in traditional casting, but to use the lowest-end basic materials as far as possible, such as pure magnesium, a small amount and a small amount of auxiliary pure metal or alloy materials, to reduce energy consumption and reduce pollution. link.

Abstract
The invention discloses a high-performance magnesium alloy parison continuous casting production line and relates to the technical fields of vacuum magnesium alloy metallurgy and material preparation. The production line is used for producing high-strength deformation magnesium alloy parison materials by whole-course vacuum protection. Equipment for the production line is provided with two vertical melting furnaces used for melting magnesium medium alloy or working alloy, wherein each melting furnace is divided into the two following parts in space: a hermetic melting chamber and a hermetic furnace body; and the pressure of the furnace body is lower than that of the melting chamber so as to form a vacuum barrier and double vacuum protection melting. Feeding cabins are arranged above furnace covers of the melting furnaces, and the opening and closing of doors of the cabins is matched with the conversion of pressure in the cabins so as to eradicate oxidization and burning of magnesium during feeding materials into hot furnaces. A heat insulation and homogenization furnace is arranged between the two melting furnaces to mix liquid coming from the melting furnaces and prepare magnesium alloy containing target components, and then the heat insulation and homogenization furnace stand still to preserve heat. An inoculation agent and leavening agent flowing addition mechanism is arranged on a gap bridge so as to effectively increase cores and prevent recession. Magnetic stirring is carried out in a crystallization process to control the pressing force and the traction speed of a tractor in real time. The equipment has compact structure, safe production and no pollution.
Description
Technical field: [0001] The invention relates to the technical field of vacuum magnesium alloy metallurgy and the technical field of material preparation, in particular to an integrated complete set of equipment for continuous casting production of high-strength deformed magnesium alloy blanks. Background technique: [0002] The use of high-strength and high-ductility magnesium alloy forgings in the fields of automobiles and motorcycles has received extensive attention. In the face of the demand for a large number of magnesium alloy forgings for parison materials, it is hoped that the melting, liquid modification and solidification of magnesium alloys will be fine. Advanced technology for process integration such as chemical and continuous casting. However, due to the high vapor pressure of magnesium, the problems of flammability, explosion and oxidation in the melting of magnesium alloys are particularly prominent. Therefore, the protection of magnesium alloy melts has alwa...
