详细说明：
适用范围： 本系列电阻炉系周期作业式，供实验室、工矿企业、科研单位作元素分析，测定和一般小型钢件做淬火、退火、回火等热处理；高温炉还可作金属、陶瓷的烧结、熔融、分析等高温加热用。
Scope：
This serial of resistance furnace is a periodically working one. which is used for element analysis and measurement by labor-atories. factories and mines and R&D institutes. and for common small-scale steels heat treatment such as quenching. annealing and tempering;the high temperature furnace is applied in high tempera-ture heating for metal. porcelain sintering. salvation and anal-ysis.etc.
结构特点：
*本系列电阻炉把炉体、控制器及热电偶等设计、制作成一体，比较、合理，整机出厂时已安装、调试，用户接上电源就能使用。克服了原来用户选用分体式电阻炉后需要再自行安装、调试所碰到一系列困难和矛盾。大大方便用户。
*炉壳选用优质冷轧钢板经折叠，焊接制成，表面采用静电喷塑处理，使设备耐用、抗高温。炉门设计合理，具有开启方便、安全，能确保炉内高温气体不外泄，达到高效、节能、环保要求。
*工作室是用耐火材料制成整体箱式炉膛、加热元件采用内置式，炉膛与炉壳间用耐火保稳材料砌筑。可以代替已淘汰的SRJX-型老产品。
*1200℃ 电炉，使用WRN-133 K型 镍鉻硅—镍硅镁 热电偶，L=350毫米。EU型铜—铜镍的补偿导线，电炉的温度控制选用智能型控温仪、LED数字显示。
Construction features：
* The series resistance furnace to furnace, controller and thermocouple, such as design, made into one, more advanced, rational, machine factory installation, commissioning, users connected to the power supply can be used. Overcome the original user after selection of split resistance furnace need to self-installation, commissioning a series of difficulties and contradictions encountered. Greatly facilitate the users.
* Furnace shell made of high quality cold-rolled steel plate by folding, welding is made, the surface electrostatic spray process, the equipment and durable high temperature. Door designed, with easy to open, secure, high-temperature furnace to ensure no gas leakage, high efficiency, energy saving, environmental protection requirements.
* Studio is made of the overall box-type furnace refractory, heating elements with built-in, between the furnace and the furnace shell masonry materials with fire-resistant security stability. Can replace the obsolete SRJX-type and old products.
* 1200 ℃ furnace, using WRN-133 nickel-chromium - nickel silicon thermocouple, L = 350 mm. EU copper - constantan wire compensation, furnace temperature control selection of intelligent temperature controller, LED digital display.
