Description

利用微波能量均匀制热生产弧形部件的装置 Using microwave energy heating means producing a uniform arcuate member

技术领域 FIELD

[0001] 本实用新型涉及一种微波制造工艺中,用微波对弧形待加工材料均匀制热的装置。 [0001] The present invention relates to a microwave manufacturing process, the heating apparatus to be processed uniformly on the arc-shaped material with microwaves.

背景技术 Background technique
