本文介绍用于修补金属模型铸造缺陷(直径1—35mm、深15mm)的耐激冷激热涂膏配方,可代替焊补这种缺陷的专门焊条。应用涂膏可以减少修理金属模型的劳动量,增加使用坚固性,降低金属模型费用。涂
This article describes a cold-resistant, heat-resistant paste formulation for repairing metal mold cast defects (1-35mm in diameter and 15mm in depth) that can replace specialized welding electrodes that weld defects. Application of plaster can reduce the labor required to repair the metal model, increase the use of robustness and reduce the cost of the metal model. Tu
