我厂生产的球墨铸铁电焊条,适用于焊补及堆焊球墨铸铁轴瓦和球墨铸铁配件,只要工艺掌握周密,可以得到与母材性能相近的焊敷金属. 一、电焊条芯的制造 1.型砂配制与造型型砂按表1配制.采用地坑双层湿型铸造.先将地面型砂按斜度15～20°用刮板刮平,后将电焊条模型轻放在地型上,填上型砂,再盖上压板,用手锤均匀敲击压板,舂实型砂,并在四边填满型砂,用手挤紧,抽出电焊条模.抽出时不得偏斜,以防型腔走动;然后再开浇口(图1).
I produced the ductile iron welding electrodes, welding and surfacing for ductile iron cast iron bearings and ductile iron parts, as long as the process well-controlled, you can get the performance similar to the base metal welded metal. Preparation and molding of sand molding Formulated according to Table 1. The use of double wet casting pit first ground sand by the slope of 15 ~ 20 ° scraping with a scraper, the electrode model will be light on the land, fill Sand, and then covered with pressure plate, with a hand hammer uniform pressure plate, 舂 real sand, and fill the sand on both sides, squeeze tight by hand, pull out the welding rod mold. Extraction should not be skewed to prevent the cavity walking; Open the gate (Figure 1).
