国产化特种焊材特种焊材分焊条和焊丝两大类,按特点可分为耐热、耐腐蚀、耐磨及其它四大类,绝大部分都是代替进口的.特种焊条还可分为高温耐热合金、耐热钢、耐腐蚀水轮机专用、耐磨难焊及模具修复等五大类,共22个品种;特种焊丝可分为三大类共13个品种.其特点是在原有成份基础上提高含碳量和含镍量,使奥氏体组织更加稳定,从而延长焊接接头在高温中的使用寿命,HP焊材是为适应30万吨乙烯及合成氨设备的需要而研制的焊材.该产品可作为模具修复用焊条,能使报废的模具获得新生,并可多次修复,多次使用.HK,HP焊材已被四川化工机械工厂、广东华元炉管公司等单位先后采用,效果良好.
Specialized domestic special welding consumables Welding electrodes and welding wire divided into two categories, according to the characteristics can be divided into heat, corrosion resistance, wear and other four major categories, most of them are imported instead of special welding can be divided into High temperature heat-resistant alloy, heat-resistant steel, corrosion-resistant turbine dedicated, wear-resistant welding and die repair, and other five categories, a total of 22 varieties; special wire can be divided into three major categories of a total of 13 varieties of its characteristics is based on the original ingredients On the increase of carbon content and nickel content, so austenitic tissue more stable, thereby prolonging the service life of welded joints at high temperatures, HP welding consumables to meet the needs of 300,000 tons of ethylene and ammonia equipment developed welding consumables. The product can be used as a mold repair electrode, scrapped mold can be reborn, and can be repeatedly repaired, multiple use.HK, HP welding consumables has been Sichuan Chemical Machinery Factory, Guangdong Huayuan Furnace Company and other units have adopted, Good effect.
