试验室SX2型箱式电炉（马弗炉）技术参数
Technical Parameters of Laboratory Box Electric Furnace

SX2型箱式电炉均系周期作业式节能电炉，升温快，空载损耗小，炉温均匀性好，供化学分析、物理测定，以及金属、陶瓷的烧结、溶解、小型钢件热处理等加热用。使用时，炉温需通过配套之温度控制器进行测量、指示和自动控制。

SX2 Box Electric Furnace is periodical operation- type energy conservation electric furnace with quick temperature rise, less loss of no load and good uniformity of furnace temperature for sintering and dissolution of metal and ceramic as well as heating treatment of small steel parts. The furnace temperature is measured, indicated and auto-controlled through its matching temperature controller.

一、用途

I. Purpose

本系列电阻炉均系周期作业式，供实验室、工矿企业、科研等单位作元素分析测定和一般小型钢件淬火、退火、回火等热处理时加热用。另其额定温度为1300℃的高温箱式电阻炉，可以作为合金钢的热处理及金属烧结、熔解、分析等高温加热用。

This cyclical-operation type resistance furnace is designed for element analysis and determination by laboratory, industrial and mining enterprises and research institutions and the heat treatment like quenching, annealing and tempering of general small steel pieces. Additionally, the 1300℃ high-temperature cabinet type resistance furnace can be used for heat treatment of alloy steel, metal sintering, melting and analysis.

二、结构简介

II. Structure

炉体由角钢及钢板制成，炉膛采用耐火材料烧结成形，炉膛与炉体之间砌筑轻质砖，950℃、1000℃的电炉发热元件分布在炉膛周围，1300℃的炉子发热分布在炉内膛室两侧，为了操作安全，1300℃的电阻炉均装有炉门开关，当炉门打开时，电炉自动切断电源，因此，只有在炉门关闭后才能加热工作，950℃、1000℃的电阻炉在使用时，取放物体，请切断电源。

Furnace body is made of angle steel and steel plate. Hearth is sinter molded with refractory material. Light-weight brick is arranged between hearth and furnace body. Around the hearth are 950℃ and 1000℃ heating elements. For the furnace rated at 1300℃, the heating elements are arranged at both sides of hearth. For the sake of operation safety, all resistance furnace rated at 1300℃ are equipped with door switch. The power supply of furnace will be cut off immediately after the door is opened. As a result, the heating operation cannot be performed in case the door is open. During the operation of furnaces rated at 950℃ and 1000℃, the power supply shall be disconnected when taking and placing objects.
