1箱式電阻爐概述
1.1構(gòu)造特征
箱式電阻爐的構(gòu)造特征主要有以下幾點(diǎn):1)外殼選用耐熱防腐漆材;2)控制面板采用PID數(shù)字顯示智能控制板,可靠性高、精密性高,配以電流表,結(jié)構(gòu)新穎;3)爐門(mén)采用加厚型,結(jié)構(gòu)更牢固,防止變形;4)爐襯采用優(yōu)質(zhì)保溫棉,保溫性能極佳;5)在不加熱的情況下,爐膛的具體溫度也會(huì)顯示出來(lái),方便觀察爐膛的狀態(tài);6)布線簡(jiǎn)單,說(shuō)明清晰,使用方便;7)具有過(guò)載、短路等保護(hù)功能;8)爐殼由優(yōu)質(zhì)厚板彎曲和焊接而成,爐子由耐火材料制成,加熱元件置于爐體內(nèi),爐體和爐身之間由絕熱材料堆疊。(剩余4090字)
