硅溶胶碳钢精铸件浇注时易氧化脱碳，熔炼浇注后需要立即盖箱防止氧化。与此同时，工艺设计的好坏也很关键，工艺设计时就应该考虑好型壳的排气、避免出现水平厚大平面、防止局部型壳壳层堆积。 Silica sol carbon steel precision castings are easy to oxidize and decarburize during pouring, and the box needs to be covered immediately after melting and pouring to prevent oxidation. At the same time, the quality of the process design is also critical. During the process design, the exhaust of the shell should be considered to avoid the occurrence of horizontal thick and large planes, and to prevent the accumulation of local shell layers.
本实用新型中所述的产品，传统的组焊工艺即不利于型壳排气防止氧化，传统的组焊工艺为一组四件，蜡件本体竖直放置，蜡件厚大平面为水平放置，涂料加固操作后容易在下蜡件厚大平面处形成浆料堆积、涂层过厚、型壳局部透气性差、型壳焙烧时此处型壳不能完全焙烧透，钢液浇注后氧化、吸气严重，铸件容易在此厚大平面位置形成表面气孔缺陷，而且也恶化了铸件的表面质量，影响了产品的一次性合格率甚至造成产品报废。 For the product described in this utility model, the traditional assembly welding process is not conducive to the exhaust of the shell to prevent oxidation. The traditional assembly welding process is a group of four pieces. The wax body is placed vertically, and the thick and large plane of the wax is placed horizontally. After the coating reinforcement operation, it is easy to form slurry accumulation on the thick and large surface of the waxed part, the coating is too thick, the local air permeability of the shell is poor, and the shell here cannot be completely roasted when the shell is roasted, and the molten steel is oxidized and sucked after pouring. Seriously, the casting is easy to form surface porosity defects at this thick and large plane position, and it also deteriorates the surface quality of the casting, affecting the one-time pass rate of the product and even causing the product to be scrapped.
