Q:How to solve casting defect casting?

Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire

Q:What is the ejection angle of the die casting (Tan Gang)?
