Cast iron material for glass die

Abstract

The invention discloses a cast iron material for a glass die. The cast iron material for the glass die is composed of, by mass percentage, 3.3%-3.5% of C, 1.9%-2.0% of Si, 0.5%-0.6% of Mn, less than 0.08% of P, less than 0.08% of S, 0.2%-0.3% of Cu, 0.2%-0.3% of Ti, and the balance Fe and inevitable impurities. According to the cast iron material for the glass die, through reasonably designed chemical components and the matching process, the manufactured glass die material is excellent in machining performance and use performance and low in cost.

Description

technical field [0001] The invention relates to a cast iron glass mold material, which belongs to the field of glass mold manufacturing. Background technique [0002] The physical and chemical properties of cast iron materials meet the current technical requirements of the daily glass manufacturing industry, and the price is relatively low, excellent casting performance and good mechanical processing performance, so it has been widely used in the glass mold industry. Accounting for more than 80% of the output value of the glass mold industry, it is in a dominant position in the selection of material applications. [0003] In order to improve the high-temperature performance of cast iron materials for glass molds, elements such as Cr, Mo, Ni and V are often added for alloying in the industry. long life. First of all, the above-mentioned alloys are all precious metals. The addition of a large amount of alloy elements will not only increase the cost of materials, but more imp...

Problems solved by technology

That is to say, what really plays a leading role is the key part of the weld layer structure, rather than the cast iron matrix itself. Therefore, the added alloy does not improve the performance of the key parts of the material, but increases the difficulty of surface hardening of the mold.
