Embodiment Construction

[0018] The present invention is described in further detail below in conjunction with embodiment.

[0019] In order to illustrate the waste water toughening treatment method of the present invention, this example takes a 100 mm thick high manganese steel liner casting cast in series as an example to illustrate the practical application of the method of the present invention in detail. The series pouring process scheme of ten high manganese steel liner castings is as follows figure 1 shown.

[0020] The specific parameters of the high manganese steel liner casting are as follows:

[0021] Casting material: ZGMn13-4

[0022] Maximum dimensions of castings: 915mm×800mm

[0023] Casting wall thickness: 100mm

[0024] Casting blank weight: 570kg

[0025] The specific implementation steps of the technical scheme of waste heat and hot water toughening treatment of high manganese steel casting cast in series are as follows:

[0026] Step S101 When molten steel is smelted, the ca...

Abstract

The invention discloses a waste heat water toughening method and device for a multi-mold assemblage casted high manganese steel casting, and belongs to the technical field of metal casting and heat treatment. The method has the beneficial effects that step connection of the water toughing method is in order, and it is ensured that after waste heat water toughening is carried out on the multi-mold assemblage casted high manganese steel casting, a single-austenite structure is obtained, so that the use performance requirement of the high manganese steel casting is met; in the waste heat water toughening process, the casting is not cracked; and compared with a conventional waste heat water toughening method, the technology complexity is reduced, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal casting and heat treatment, and in particular relates to a heat treatment method for high manganese steel castings, and also relates to a treatment device for the method. Background technique [0002] The wear resistance of high manganese steel castings will be enhanced after hot water toughening treatment, but the quality of hot water toughening treatment will directly affect the service life of high manganese steel castings. Since the waste water toughening treatment of a single high manganese steel casting requires heating and heat preservation, the production cycle is long and the production cost is high. Therefore, at present, the high manganese steel castings adopt multiple pieces of high manganese steel castings to be cast in series for the hot water toughening treatment, and the casting is heated to 1000 ℃ ~1100℃, water cooling after heat preservation, so that the carbides dissolved in the a...
