注意事項(xiàng)
1、電爐絲在設(shè)計(jì)時(shí)應(yīng)根據(jù)功率接線方法，合理的表面負(fù)荷，正確選用絲徑；
2、電爐絲在安裝前應(yīng)對(duì)爐膛全面檢查，清除鐵素體，結(jié)碳，與電爐上接觸的隱患，避免短路，以防造成爐絲擊穿；
3、電爐絲在安裝時(shí)應(yīng)按設(shè)計(jì)的接線方法正確連接；
4、在使用電爐絲前應(yīng)檢查控溫系統(tǒng)的靈敏度，以防溫失靈，造成電爐絲燒毀。 加熱棒，電爐絲，電熱管，單頭電熱管，鑄鋁加熱板生產(chǎn)企業(yè)-鹽城市瑞高電熱設(shè)備有限公司，cnruigao
