Improved Development And Safety Evaluation Of Deoxidized Aluminum Pellet High-Temperature Continuous Casting Production Line

The use of deoxidized aluminum pellet high-temperature continuous casting production lines in enterprises have problems such as flashing of cast products,large number of workers and high labor intensity,and hidden safety hazards caused by backward equipment,which can no longer meet the needs of fierce market competition.This subject is based on the safety evaluation of the production line,the numerical simulation of the temperature field of deoxidized aluminum particles,the overall improvement of the production line and the design of the packaging device to solve the existing problems.The main contents are as follows:In terms of safety evaluation,the production line is analyzed for hazards and harmful factors,and the pre-risk analysis method and the accident tree analysis method are used to qualitatively and quantitatively analyze the prone accidents in the production line operation process,and it is concluded that personnel burns and heavy objects fall The probability of accident is the highest,and accident prevention measures are proposed from the perspective of use and production management for this point.In the numerical simulation of the temperature field,the ANSYS simulation software is used to model the actual size of the deoxidized aluminum particles and their molds,and the boundary conditions are set according to the actual production situation to obtain the time required from pouring to cooling to packaging temperature.On this basis Calculate the line speed of the maximum production efficiency under the limited production line length to prepare for the subsequent improvement of the overall plan.In terms of overall scheme improvement,the improvement design is carried out under the guidance of safety evaluation results,actual needs of enterprises and line speed under the maximum production efficiency.The whole layout presents a zigzag layout,from front to back is pouring,mold cooling,demoulding,product cooling and packaging.The pouring mechanism and packing device are designed,and the crank rocker with quick return characteristics is adopted As the transmission of pouring mechanism,the mechanism realizes the pouring action of slow pouring and quick return.On the basis of reducing the return time,the problem of product flash is solved and the work efficiency is improved.The design of vertical automatic packing and receiving mode can not only reduce the number of workers but also reduce the labor intensity.
