Description

A kind of technique making imitation of an ancient bronze and its smelt roasting system

Technical field

The present invention relates to the production field of imitation of an ancient bronze, more particularly, to a kind of technique for making imitation of an ancient bronze and its Smelt roasting system.

Background technique

Bronze ware is referred to as " gold " or " Ji Jin " in ancient times, is the alloy of red metal and other chemical element tin, lead etc., copper Rust is in dark green；The use of bronze ware is popular in period of late Neolithic to Qin Han dynasty, the most smart with the implements of Shang and Zhou Dynasty Beauty；Although the bronze ware of ancient times is national historical relic, it is protected, since the moulding of bronze ware is exquisite, artistic value is high, and has There is dense cultural spirit, some fine implied meanings can be represented, people often buy some bronze wares modelled after an antique, as dress Therefore ornaments have also driven the development of imitation of an ancient bronze industry；

Imitation of an ancient bronze is the bronze, brass or copper ware that modern copys out according to the picture of ancient bronze ware or ancient bronze ware, since modern is set The standby permission with condition, the manufacture craft of modern imitations bronze ware and ancient bronze production cannot be mentioned in the same breath, and especially exist The technique for making large-scale imitation of an ancient bronze and batch making imitation of an ancient bronze these two aspects is more perfect, and producing efficiency is higher, and And the bronze modelled after an antique produced is also more exquisite；But in the manufacturing process of imitation of an ancient bronze, pollution problem is always existed, During the production of plaster mold and the polishing of bronze ware, what is be primarily present is dust pollution, and in drying plaster mold and is melted During copper metallurgy material, in order to observe the state of plaster mold and copper material, and convenient for scooping out copper liquid, general smelting from crucible With all outdoor progress of roasting process, not there is only smoke pollution, and waste of energy.

Summary of the invention

In order to overcome the shortcomings in the background art, the invention discloses a kind of techniques and its smelting for making imitation of an ancient bronze Roasting system can not only produce more exquisite imitation of an ancient bronze, and producing efficiency greatly improves, and manufacturing process is also more Add cleanliness without any pollution.
