陶瓷型铸造,通常是用含耐火泥的水玻璃制成的型砂加固层和陶瓷灌浆薄层所形成的双层铸型来生产的。然而,这种铸型在焙烧或浇注时,由于加固层产生变形而影响铸件质量。明斯克B．и．列宁拖拉机厂,为了用一个陶铸型制取年产30多件的工具铸件,设计了一种随形的金属外型(外壳)作加固层的复合陶瓷型。该陶瓷型铸造操作过程如下:1．准备金属支承金属外型(即加固层);2．将金属外型放在光洁的模上(金属外型与模 Ceramic casting is usually produced by a two-layer mold formed of a sand-reinforced layer of refractory-containing water glass and a ceramic grout. However, this type of castings, when fired or cast, can affect the quality of the castings due to the deformation of the reinforcement layer. Minsk и. Lenin tractor factory, in order to use a ceramic mold for the production of castings with an annual output of more than 30 pieces, with the design of a metal shape (shell) for the reinforcement of the composite ceramic type. The ceramic casting operation is as follows: 1. Prepare metal support metal appearance (ie, reinforcement layer); 2. The metal appearance on the clean mold (metal appearance and mold
