ボトムローディング炉

ボトムローディング炉

Bottom-Loading Furnace are high-temperature furnaces suitable for large workpieces and mass production, and are widely used in sintering, annealing, and material handling processes. This equipment uses an electric lifting mechanism for loading and unloading, making it suitable for materials that are difficult to handle manually or that are large in size.

In actual use, the workpiece enters the furnace chamber via the lifting platform. The heating process is stable and reliable, improving production efficiency and reducing human error. This equipment is suitable for industrial production, as well as laboratory and research applications. Smaller units are also commonly used in denture processing, zirconia crown sintering, and powder material processing.

製品の特徴

  1. Convenient and Safe Material Loading and Unloading via Lifting Platform

The electric mechanical control platform lifts and lowers the material, feeding it into the furnace from the center. This solves the problem of difficult manual operation for large or irregularly shaped materials. The lifting is smooth and reliable, allowing operators to load and unload materials without approaching the high-temperature furnace opening, significantly reducing the risk of burns.

  1. Customizable Furnace Chamber and Functional Expansion

The bottom-loading furnace chamber size and other functional expansions can be customized according to customer requirements, such as atmosphere protection systems, vacuum systems, rapid cooling systems, and exhaust gas treatment devices, meeting the personalized needs of different materials and processes.

  1. High-Capacity Sintering for Large-Scale Production

This equipment is designed for large-scale production. The large-capacity furnace chamber, combined with the electric lifting platform, enables rapid loading and unloading, shortening production auxiliary time and improving equipment utilization and production capacity.

  1. Wide Temperature Range

The standard operating temperature ranges from below 1200℃ to 1700℃, covering high-temperature sintering and heat treatment processes for most materials.

  1. High-Quality Furnace Lining, Insulating and Energy-Saving

The bottom-loading furnace lining uses vacuum-formed high-purity alumina lightweight material, which features high operating temperature, low heat storage, resistance to rapid heating and cooling, no cracking, no slag shedding, and excellent insulation performance. Energy saving is significantly improved compared to traditional electric furnaces, greatly reducing operating costs.

  1. Intelligent Control Panel, Fully Functional

The control panel is equipped with an intelligent temperature regulator, power switch, main heating start/stop button, voltmeter, ammeter, computer interface, etc., providing a clear view of the system's operating status and intuitive and easy operation.

  1. Multiple Safety Protections

An integrated modular control unit is designed with dual-loop control and dual-loop protection functions, providing comprehensive protection against overshoot, over-adjustment, under-adjustment, thermocouple breakage, 位相損失, over-pressure, over-current, over-temperature, 電流フィードバック, and soft start. Optional functions include door-opening power-off and over-temperature alarm to ensure safe equipment operation.

Furnace structure and materialThe electric furnace body adopts an advanced double-layer cold carbon steel furnace body structure. The effective cold air guide partition ensures the overall cold air circulation, and finally cools the heating element conductive sheet and discharges it out of the furnace, avoiding high-temperature oxidation of the heating element conductive sheet; 良好な労働環境の確保.
Opening modeThe furnace door is hinged on the shaft, with 360-degree rotation and opening. The furnace door lock is equipped with elastic inertia on the side of the furnace door, which can effectively lock. The elasticity of the lock absorbs the expansion and swelling of refractory materials, ensuring free expansion and contraction of fire-resistant materials during thermal expansion and cold contraction, and effective sealing.

Multipoint temperature control Under the working state of the furnace body, high temperature opening and closing of the furnace door cuts off the main heating circuit, which greatly protects the electric risk of high temperature contact.
Safe temperature controlAdopt closed-loop technology controllable module trigger control, phase-shift trigger control or zero-crossing trigger and other methods. 出力電圧, current and power can be continuously adjusted, with constant voltage, constant current or constant power characteristics. The inner loop is current, and the outer loop is voltage. When the sudden load or load current exceeds the limit value, limit the output current of the regulator within the stable voltage range, ensure the normal operation of the regulator, and at the same time adjust the voltage, so that the output current of the regulator is limited in the stable current range. Under the premise of sufficient adjustment margin, maintain the stability of output current and voltage, so as to achieve the control effect of protecting heating elements from over-current, voltage shock, etc., and reach the full controllable control rate and control accuracy.
Temperature curve settingAdopt intelligent temperature control instrument, with various adjustment methods such as PID, artificial intelligence APID or MPT, with self-calibration and self-learning functions, no overshoot and no stop of temperature control characteristics, and 50-segment program control function.
