Design And Study Of Ingot Mould Sweeping Device

Ingot mould sweeping is one of the key technologies to improve the quality of steel ingots.The surface roughness of ingot mould is significant to the effect of ingot casting,but there are quite a lot of disadvantages for the current applied sweeping ways such as the manual disc grinding,the shot blasting machine or the chain grinding technology etc.In order to improve the working environment of operators,increase the surface roughness of working pieces and grinding efficiency,this paper studies the application of rolling brush type ingot mould sweeping device in lieu of traditional manual grinding and machine grinding ways.This paper focuses on the design engineering of sweeping device based on the functional principle and carries out the analysis and verification of critical structures.This paper carries out the functional engineering of the technical specification of general layout,material properties and grinding characteristics of ingot mould sweeping device focusing on the functional principle and accomplishes the analysis of functional principle to determine the general layout of steel brushes for ingot mould sweeping and the technical parameters such as the number of sweeping units,the arrangement of sweeping mechanism and the setting-up of drive unit etc.;and performs the design engineering of revolving device for working table combining with the functional principle and deduces the calculation equation for selecting the rolling brush motor.The material most suitable for brush is selected in accordance with the variable properties of different brush materials and wearing properties.The wearing properties of various brush materials is analyzed with establishing the 3D model of brushes and residual slags by means of finite element method via Deform-3D program.It shows that the arrangement density of brush will influence the sweeping effect,i.e.brushes with different diameters have different bending resistant property.This paper applies the advanced simulation module of UG10.0 to establish the model and analyze the bending deformation condition of single steel wire under loading to select the brush diameter suitable for the device in accordance with the relationship between stress condition and yield strength.This paper makes the design engineering of dimension and structure of sweepingbrushes in accordance with the working principle and functional requirements of brush and analyzes the stress deformation condition of steel wire of brush.On a series of simplification of this part,this paper simulates the sweeping process with Deform-3D program by means of establishing the 3D model of sweeping brush and work piece with SOLIDWORKS program.The effect of removal amount of brushes is determined by means of applying various boundary conditions to the simulation model and the resulting pressures;It accomplishes the data analysis of surface roughness of work pieces and slag temperature by controlling the variation of rotation speed of brushes,which deduces the effect of rotation speed to the overall appearance and temperature of work piece.The papers first establish the prototype model of ingot mould sweeping device with SolidWorks based on general layout and execution type by utilizing the function principle and design method and simplify the model of sweeping frame.It performs the static and dynamic analysis of sweeping frame with ANSYS Workbench to verify the stability during operation,which proves the accuracy of design engineering.Finally,it finishes the machining and test run of prototype machine and verifies the actual working effect.
