What are the advantages of forced convection tempering furnace?

/in /by

A forced convection tempering furnace is a type of heat treatment equipment used primarily for tempering glass. The process of tempering involves heating the glass to a specific temperature and then rapidly cooling it, which increases its strength and resistance to thermal stress.Forced convection tempering furnaces offer several advantages over traditional tempering methods.

Advantages of Forced Convection Tempering Furnace

Forced convection tempering furnaces

Uniform Temperature Distribution: Forced convection ensures that heat is evenly distributed throughout the furnace chamber. This leads to more uniform tempering, reducing the risk of uneven hardness or strength in the material being treated.

Faster Heating and Cooling: The active circulation of air or another medium accelerates the heating and cooling processes. This results in shorter cycle times, increasing production efficiency.

Energy Efficiency: Due to the improved heat transfer rates, forced convection furnaces often require less energy to achieve the desired temperature profile, leading to lower operating costs.

What is the production process of convection tempering furnace?

/in /by

A convection tempering furnace is a specialized piece of industrial equipment used in the glass industry to heat-treat glass sheets. The process, known as tempering, involves heating the glass to a temperature just below its melting point and then rapidly cooling it. This treatment strengthens the glass, making it more resistant to impact and thermal stress.
The production process of a convection tempering furnace, used for tempering glass, involves several key steps to ensure the glass is properly heated and cooled for strength and safety.

Convection tempering furnace production process

1. Glass Loading:

The glass sheets are loaded onto the furnace’s conveyor system. The glass can be of various types, sizes, and thicknesses, depending on the specific application.

2. Preheating:

The glass is preheated as it enters the furnace. This helps to gradually increase the temperature of the glass to avoid thermal shock, which could cause breakage. Preheating is typically done in the early zones of the furnace.

3. Heating:

The glass moves into the main heating chamber of the furnace. In a convection tempering furnace, both radiation and convection are used to heat the glass.

Convection heating is where hot air is circulated within the furnace to ensure even heating across the glass surface. This is especially effective for low-emissivity (Low-E) glass, where conventional radiation heating might be less effective.

The glass is heated to a temperature above its annealing point, usually between 600°C and 700°C (1112°F to 1292°F), depending on the type of glass.

4. Soaking:

Once the glass reaches the required temperature, it is soaked at that temperature for a specific period. This allows the heat to penetrate the entire thickness of the glass uniformly, ensuring even tempering.

5. Quenching:

After heating, the glass is quickly moved to the quenching section of the furnace. This is a critical step where the glass is rapidly cooled using powerful air jets.

What is the reduction ratio of high pressure grinding rolls?

/in /by

The reduction ratio of a High-Pressure Grinding Roll (HPGR) refers to the ratio of the feed particle size to the product particle size after crushing. It’s an important parameter in evaluating the efficiency and performance of the HPGR.

The reduction ratio can vary widely depending on several factors, including:

Feed Size: The size of the material fed into the HPGR.

Hardness and Type of Material: Different materials break down differently under pressure.

Operating Pressure: Higher pressure generally results in a finer product and a higher reduction ratio.

Roll Surface Design: The texture and pattern of the roll surfaces can affect the size reduction process.

Moisture Content: The moisture content of the material can influence the efficiency of size reduction.

Typical Reduction Ratio Range:

high pressure grinding rolls

Standard Reduction Ratio: HPGRs generally achieve reduction ratios in the range of 1.5:1 to 3:1. This means that the output particle size is typically between on third and two-thirds of the input size.

Higher Reduction Ratios: In some cases, especially when processing softer or more friable materials, or when the HPGR is used as a tertiary or quaternary crusher, the reduction ratio can exceed 3:1, potentially reaching 4:1 to 5:1 or higher.

Factors Affecting Reduction Ratio:

Feed Size and Material Characteristics:

Feed Size: Larger feed sizes generally result in lower reduction ratios.

Material Hardness and Abrasiveness: Harder and more abrasive materials typically require more energy to reduce in size, often resulting in lower reduction ratios.
