LAD tempering furnace is an industrial furnace used to heat treat ferrous metal products and improve their toughness. In metallurgical terms, an alloy’s toughness describes its ability to elastically deform and absorb energy before the material breaks. This is part of the complex relationship between metal ductility and strength, with high toughness values requiring a subtle intersection of the two. Typically, high-strength materials are not ductile and vice versa, but heat treating certain materials in a tempering furnace can unlock beneficial values in both axes of mechanical dynamics.
To temper glass, a tempering furnace heats the glass to extremely high temperatures, usually over 600 degrees Celsius. The furnace then uses air jets to cool the glass evenly and quickly. The rapid cooling process is called quenching. During the tempering process, the glass undergoes extreme compression and gains resistance to impact and thermal shock. The heating and cooling processes that occur during tempering increase the strength of the glass and reduce the risk of cracking or shattering. However, if tempered glass breaks, it will break into several small pieces with spherical edges rather than large, sharp pieces. This reduces the risk of serious injury.
Tempering is a process that dates back thousands of years, and the theory behind it has remained relatively unchanged over the centuries. It is the process of achieving maximum strength and elasticity in iron-containing or iron-based metal products through a limited degree of heat treatment, usually following a quenching process. Modern tempering processes may be similar in theory to ancient processes, but the equipment used today has been greatly improved. For example, quenching, which once required a uniform liquid (such as mercury) to properly precipitate the hardening of ferrous alloys, can now be performed using vacuum or airflow techniques. The tempering furnace also has the new function of “softening” the ferrous metal after the product is quenched.
Tempering furnaces use ceramic heating elements lined with wires or coils to evenly heat the sample chamber to different heating ranges depending on the material properties required for the product. Iron-based metals are heated to 300 to 750°C (572 to 1382°F) in a tempering furnace to promote phase transformation within the martensitic structure, reducing the material’s hardness while increasing its ductility. Basically, a quench furnace accurately maintains temperature levels and temperature uniformity throughout the sample chamber to eliminate the possibility of warping or breaking of the metal.
Automotive glass tempering furnaces have many advantages over standard glass. Glass tempering furnaces and tempering processes make tempered glass stronger and safer than standard glass. This reduces the risk of the glass breaking, or if the glass breaks, the risk of injury. Broken tempered glass is easier to clean than standard broken glass. In addition to being safer and stronger, tempered glass is also more resistant to scratches, damage, and heat. Due to its high tensile strength, tempered glass is considered bulletproof and weatherproof, making it ideal for applications such as storefront systems or doors and windows. Commercial and residential.
Furthermore, our tempered glass furnace machine has a programmable thermostat for temperature regulation. The temperature of the glass furnace can be adjusted in 1 degree Celsius increments. The furnace is designed to heat and cool the glass in an even manner. Tempered glass generally uses airflow cooling. If the tempered material becomes too hot for the user, an alarm will sound. If the temperature is too high, the machine will automatically cut off the power supply. Tempered glass furnace machines are also often called tempering machines. The temperature of the tempered glass is quickly cooled by forced ventilation. The inside of the glass is exposed to the air, which is what makes tempered glass tough and strong. Meets minimum fire protection standards of E30 and Fox. This is how tempered glass is produced. This process is called thermal tempering.
