The invention discloses a separable type automatic vacuum pumping storage container. The separable type automatic vacuum pumping storage container comprises a box body and a vacuum control device, wherein a vacuum pumping passage is formed in the box body; the vacuum control device is detachably connected with the vacuum pumping passage; one end of the vacuum pumping passage is communicated with an inner cavity of the box body; a sealing joint is arranged on the other end of the vacuum pumping passage; the vacuum control device is provided with a gas pumping nozzle; the gas pumping nozzle is inserted in the sealing joint and is in air-tight connection with the sealing joint when the vacuum control device is connected with the vacuum pumping passage, and the inner cavity of the box body is enabled to keep a vacuum state by the vacuum control device by pumping gas when the air pressure of the inner cavity of the box body is greater than a preset threshold value. Compared with an existing vacuum storage box, the separable type automatic vacuum pumping storage container disclosed by the invention has the advantages that more effective vacuum pumping can be realized, and the vacuum degree in the box body can be better maintained; more convenience is realized when the separable type automatic vacuum pumping storage container is used by a user, and the requirements on vacuum pumping or vacuum releasing can be realized without too much operation.

The invention relates to continuous casting forming equipment and a process for an electromagnetic ejection filling core of a cladding material, belonging to the field of the continuous casting processing in metal material. The equipment provided by the invention comprises upper and lower temperature control crystallizers, a temperature measuring instrument, a metal temperature control furnace of the core, an outer metal temperature control furnace, a filling core tube, an electromagnetic pump, a secondary cooling device, a limiting device, a pressure sensor and a recession device, wherein the upper and lower temperature control crystallizers and a metal liquid filling core tube of the core are arranged on the same axis along the continuous casting direction; the electromagnetic pump is installed outside the upper and lower temperature control crystallizers and assembled on the same axis with the upper and lower temperature control crystallizers; the upper end of the metal liquid filling core tube of the core is connected with a metal temperature control crucible of the core, and the lower end is inserted into outer metal liquid; the outer metal liquid and the metal liquid of the core are isolated through the metal liquid filling core tube of the core; the outer metal liquid is cooled to form an outer metal tube; the metal liquid of the core is poured into the outer metal tube through the metal liquid filing core tube of the core; and a composite blank is ejected out by exerting the pressure through the electromagnetic pump. The invention eliminates cracks and vibration marks which are easy to occur in a common continuous casting blank, can continuously cast the cladding material once, obtains a composite interface of high quality and has the advantages of low production cost and high efficiency of subsequent processing.
