Casting blank arc angle forming device

Abstract

The invention relates to a casting blank arc angle forming device. The casting blank arc angle forming device is composed of a portal frame, a vertical floating beam, floating beam lifting air cylinders, horizontal movable sliding blocks, eccentric wheels, horizontal guide rails, movable sliding block horizontally-moving air cylinders, arc angle forming nozzle supports and arc angle forming nozzles. The vertical floating beam is assembled on the portal frame through the eccentric wheels and the floating beam lifting air cylinders, and the vertical floating beam can vertically slide through thevertical floating beam air cylinders. Two wheel assemblies and the vertical floating beam are vertically arranged. The horizontal movable sliding blocks are clamped to the vertical floating beam through the guide wheels. The movable sliding block horizontally-moving air cylinders are arranged on the horizontal movable sliding blocks. Piston connection rods of the movable sliding block horizontally-moving air cylinders are connected to the vertical floating beam. The heating nozzle supports are connected to the horizontal movable sliding blocks through bolts, the heating nozzles are clamped tothe heating nozzle supports, and the positions and the angles of the heating nozzles are adjusted by adjusting the heating nozzle supports. By means of the casting blank arc angle forming device, thearc angle forming nozzles can precisely carry out forming on the casting blank corners, corner defects of a casting blank are removed, the purpose that the corners of the casting blank are in arc shapes is achieved, and the casting blank quality is improved.

Description

technical field [0001] The invention relates to a billet arc angle forming device. Background technique [0002] With the continuous improvement of people's requirements for the quality of steel products, manufacturers have to deal with the edge defects of the slabs. However, the continuous casting slabs poured in major steel plants are right-angle continuous casting slabs, and the defects at the right angles It is the most serious. Before entering the next process, processing the right angle of the slab into a circular arc can effectively prevent corner defects from flowing into the next process. At present, the most mainstream treatment method is manual flame cleaning. Workers hold special burning guns and adjust The flame and the speed at which the operator walks ensure the quality of corner cleaning. However, the artificial flame cleaning method has the following disadvantages at present: 1. There are extremely high requirements for the workman's operating skills and ju...

Problems solved by technology

However, the artificial flame cleaning method currently has the following disadvantages: 1. It has extremely high requirements for workers' operating skills and judgment experience

2. Low cleaning efficiency and unstable cleaning quality

3. The temperature of the casting slab needs to be lowered so that the workers are close to the slab for cleaning, and the subsequent process needs to be reheated, resulting in a waste of energy
