Abstract

The invention relates to a preheating induction cladding strengthening process of a glass mold and application thereof. The process comprises the steps of performing sandblasting and roughening on the surface of a part to be strengthened of a workpiece, preparing coating, preheating before melting, heating and remelting at the same time, and preserving heat and cooling. The preheating induction cladding is introduced into the surface strengthening of the glass mold, the problems that the coating is not incompact, more defects exist, the strengthening property is bad, service life is short, and the like in the traditional strengthening process are overcome, and the problems that the cost is high, the efficiency is low, and the temperature distortion easily occurs in a laser cladding strengthening process are overcome; the preheating induction cladding strengthening process is applied to both the new product strengthening of glass and the old product remanufacturing of the glass mold, desquamating and scratching failure are not easy to generated, and the service life is remarkably improved. According to the process provided by the invention, the high performance and high quality of the glass mold surface strengthening are achieved, the high speed and high efficiency, the high finished product rate, the automatic control, the low production cost in the strengthening process are realized, the service life of the glass mold is remarkably prolonged, free pollution and green and environmental protection in the whole manufacturing process are achieved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a glass mould's preheating induction fusion coating strengthening process and its application. Background technique [0002] During the forming process of glass products, the mold is frequently in contact with the molten glass, and suffers from oxidation, growth and thermal fatigue. At the same time, the surface of the mold is worn due to the friction of glass products, which requires the mold material to have good heat resistance, wear resistance, corrosion resistance, thermal shock resistance, oxidation resistance, growth resistance, and thermal fatigue resistance. It is the goal pursued by the industry to realize the high performance and long life of the glass mold through the surface strengthening process. [0003] The Patent Application Publication No. of "A Surface Strengthening Method for Glass Mold" published by the National Patent Office: CN102363883A. This patent stren...
