Atmosphere protection program-controlled box-type electric furnace SDXL-1616 detailed introduction

SDXL-1616 atmosphere protection program-controlled box-type electric furnace performance characteristics::

■It can be passed into the degrading gas so that the high temperature heating workpiece will not produce oxidative decarburization

■High-aluminum inner tank, silicon-molybdenum rod heats up, the outer shell is made of high-quality thin steel plate, and the surface is sprayed with plastic

■The instrument has high accuracy, the display accuracy is 1 degree, and the accuracy is up to plus or minus 2 degrees under the constant temperature state.

■The control system adopts LTDE technology, with 30-band programmable function, two-level over-temperature protection

The SDXL-1616 atmosphere protection program-controlled box electric furnace model is in accordance with the national machinery industry JB4311.7-91 standard. The electric furnace has a LTDE programmable control system. The electric furnace shell is made of high-quality cold plate and steel. The production process has air inlet and outlet devices, which can pass in the degrading gas so that the high-temperature heating workpiece will not produce oxidative decarburization. This electric furnace is suitable for other high-temperature annealing, tempering and other heat treatment processes that require various gas protection. Forty-segment microcomputer control with program, with powerful programming function, can control heating rate, heating, constant temperature, multi-band curve arbitrarily set, optional software can be connected to a computer, monitor, and record temperature data, making the reproducibility of the test possible. The instrument is equipped with electric shock, leakage protection system and secondary over-temperature automatic protection function to ensure the safety of the user and the instrument. This furnace is suitable for low-purity atmosphere protection experiments. If high-purity atmosphere protection is required, please choose our company’s vacuum atmosphere according to your needs. Chamber furnace and vacuum chamber furnace
