A new type of optimized riser structure was proposed. in which a low-emissivity board was inserted into the hollow interlayer of the material to increase the yield of the steel ingot. The insulation effect of different riser heights on the solidification process of steel ingot is numerical simulated. The results show that when the riser height can be reduced from 350 mm to 300 mm. https://parisnaturalfoodes.shop/product-category/face-toner/
