Muffle furnace instructions and operating procedures


SX2 series resistance furnace is a transformation and upgrading of old products. It is widely used in various laboratories, industrial and mining enterprises, scientific research units for elemental analysis and measurement, and general small parts quenching, annealing, tempering and other heat treatment operations.

Structure introduction

This series of resistance furnaces are all rectangular, the furnace shell is made of high-quality cold-rolled steel plate, the studio is made of high-quality silicon carbide refractory material, and the high-quality insulation material between the furnace and the furnace shell is used as insulation layer. The heat loss at the furnace mouth is increased, the temperature uniformity in the furnace is improved, and a heat shield made of high-quality refractory material is installed inside the furnace door.

The furnace temperature measurement, indication and adjustment automatic control system is completed by the XMT series temperature controller. The instrument is equipped with a break protection device. When the temperature measurement thermocouple is disconnected during the heating process, the power supply can be automatically cut off to ensure the electric furnace and The safety of the workpiece being processed.

Use safety procedures:

1. During the high temperature experiment, the burning dish and the magnetic boat must be taken with tweezers. After the burning, the gray dish and the magnetic boat should be placed on the high temperature resistant material, and should not be taken by hand; Should be operated with gloves.

2 , before the use of high temperature furnace, pay attention to check whether the thermocouple is in the specified position, otherwise it will cause abnormal temperature rise in the high temperature furnace.

3. When using high-temperature equipment, if there is any leakage, power failure or burning of the furnace wire, stop using it and report it to the technician for timely disposal.

4 , the instrument should prevent the intrusion of dust and corrosive gas, long-term need not be covered, zui good regular heating to heat the tide.

5 , It is forbidden to burn and bake substances in high temperature equipment and dry box, which are corrosive, flammable, explosive, volatile or toxic.
