Embodiment Construction

[0038] In order to detail the technical content, structural features, achieved goals and effects of the present invention, the following will be described in detail in conjunction with the accompanying drawings.

[0039] Casting devices for large-section castings, such as figure 1 and figure 2 As shown, it includes a sandbox, a hydraulic metal plate 3, a water-cooled metal plate, a hydraulic jack, a water-cooled pipeline, a hydraulic oil pipeline, a right runner 10, a left riser 11, a heat-resistant coating 12, a fixing component 13, and a controller and casting 16.

[0040] like figure 1 As shown, the sandbox, which includes an upper sandbox 2 and a lower sandbox 1, is composed of a bottom plate and an enclosure plate. The bottom plate and the enclosure plate of the lower sandbox 1 form a concave box with an upward opening, and the enclosure plates at the left and right ends of the lower sandbox 1 Respectively provide rectangular holes, the rectangular holes are fixedly c...

Abstract

The invention provides a casting device and process method for large-section castings. The device includes a sandbox, a hydraulic metal plate, a water-cooled metal plate, a hydraulic jack, a water-cooled pipeline, and a hydraulic oil pipeline. The first end of the thin-walled rectangular tube is fixedly connected, and there are five hydraulic oil circuits inside the hydraulic metal plate. The hydraulic jack is equidistantly installed on the upper surface of the hydraulic metal plate in the corresponding length range of the casting. connection, the second end of the hydraulic jack is connected to the first water-cooled metal plate, and there are three equidistant water-cooled pipelines inside the water-cooled metal plate. The automatic compensation system controller drives the corresponding hydraulic jack to rise by H=1mm according to the pressure value of the hydraulic jack every time it increases by 20%, so as to resist the concave deformation of the casting. The invention adopts built-in water cooling and automatic air gap compensation technology to speed up the cooling speed of the casting and improve the mechanical performance and production efficiency of the casting.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting device for large-section castings and a casting method thereof. Background technique [0002] As a common type of special casting, large-section castings, such as rolls, ultra-thick-walled square tubes, and wide-thick plates, are widely used in heavy industry, aerospace and large military equipment. Large-section castings have a relatively simple structure, but their walls Thick and large cross-sectional area, it is easy to form casting defects such as shrinkage porosity, shrinkage cavity, segregation, air entrainment and cracks during the casting process. Taking ultra-thick-walled square pipes as an example, ultra-thick-walled steel pipes are widely used in bridges, high-rise steel structure buildings, solar power generation, wind power generation, shipbuilding, and oil drilling equipment. The manufacture of ultra-thick-walled square tubes usually relies on welding and casting ...
