Technical Advantages

Insulation Layer Technology
Each preheating chamber and tempering furnace adopts high-performance heat insulation materials. The inner chamber is made of high-quality stainless steel with acid, alkali, and high-temperature resistance, and the outer materials are all high-quality stainless-steel plates and fixed with square steels. The thermal insulation is made of aluminum silicate materials that can withstand more than 1000 degrees Celsius. The thickness of the thermal insulation layer is high, and the thermal insulation effect is excellent. The temperature of the outer wall of the furnace is not higher than 50 degrees Celsius. It effectively prevents heat loss during the heating process and greatly reduces heat energy consumption.
Temperature Control System
The electric heating system can automatically control the temperature, adopting PID+SCR control, and the temperature control range is RT-550℃. The computer can accurately control the temperature according to the settings, combined with the electrical system and the temperature control module, and can design different heating power and heating time, and perform analog PID adjustment on the power to meet the process temperature requirements. The control accuracy can reach ±1℃. The temperature is controlled in two ways, one to the PLC and the other to the on-site display. With over-temperature protection and overload protection.
Efficient Air Circulation System
The top of the preheating (slow cooling) furnace is equipped with several heat-resistant circulating fans and coolers of well-known brands, which are controlled by frequency conversion speed control to achieve the best heat circulation and cooling effect. The highest temperature it can withstand is 550℃.
Heating System
Heaters are installed around the furnace, controlled by a SCR to ensure the uniformity of temperature. The heating pipe installation is simple and it is easy to replace. The heating chamber can be designed with double heating chambers and multiple heating chambers according to the user's output requirements, and the production method is flexible.
Furnace Door System
Use left and right sliding doors for the exchange furnace door. It is driven by a motor gearbox, and the limit switch locates the opening and closing of the door, which is safe and reliable.

Machine Introduction

The chemical glass tempering furnace is mainly used for the strengthening treatment after the glass polishing, cleaning, and inspection, to enhance the heat and shock resistance of the glass surface. According to the plasma diffusion mechanism, an ion exchange process occurs between the alkali ions in the glass and the potassium ions in the salt, which improves the composition of the glass surface and causes compressive stress on the glass surface. After tempering, the heat resistance and shock resistance of the glass is greatly improved. After treatment, the glass has high strength and good thermal stability. The surface of the glass remains smooth, without deformation, can be cut, and does not explode. It is suitable for all kinds of a glass of any thickness and shape.

The chemical tempering workflow mainly includes feeding, preheating, tempering (ion exchange), salt dropping, slow cooling, and discharging. The operator inserts the glass to be tempered into the basket, pushes it to the feeding position at the front end of the tempering furnace, lowers the lifting hook of the preheating furnace to a low position, and then lifts the basket into the preheating furnace by the lifting hook for preheating. After the preheating is completed, the program automatically opens the furnace door of the tempering furnace, and the mobile machine moves the hanging basket of the preheating furnace directly above the tempering furnace, and the hanging basket is lowered to the tempering furnace for tempering. After the tempering time set by the process, the chemical tempering is completed. Lift and dripping salt, the furnace cools slowly, and then the hanging basket is put down at the end to take out the glass.
