Glass tempering furnace is a key equipment in the glass production line, which directly affects the operating efficiency of the entire production line and the quality of glass products. Reasonable selection of glass tempering furnace can not only improve production efficiency and extend the service life of equipment, but also effectively save energy consumption and reduce operating costs.

Principles of glass tempering furnace equipment selection

1. Capacity matching principle

The design capacity of the glass tempering furnace must match the actual capacity of other links in the production line. If the capacity of the tempering furnace is too large, it will cause waste of energy and labor; if the capacity is too small, it will restrict the efficiency of the entire production line. Therefore, when selecting, it is necessary to combine the actual situation of the production line to select a better tempering furnace specification.

2. Process compatibility principle

The tempering process requirements of different glass varieties are different, so the design of the tempering furnace must be compatible with the process of the required tempered glass variety. For example, although the tempering processes of flat glass, automotive glass, laminated glass, etc. have something in common, the parameter settings in the heating, cooling, and transportation links are different. Therefore, it is necessary to select a suitable tempering furnace model based on the company’s existing and future product planning.

3. Energy-saving and environmental protection principles

With the increasing attention paid to energy conservation and environmental protection, the glass industry is also facing higher environmental protection requirements. Tempering furnaces are high-energy-consuming equipment, and equipment with high energy efficiency ratio and low pollution emissions should be given priority, which can not only reduce operating costs but also meet environmental protection requirements. In addition to the energy-saving performance of the equipment itself, the design of energy-saving links such as waste heat recovery should also be considered.

Precautions for selecting glass tempering furnace equipment

1. Clarify the size requirements of the tempering furnace

Glass tempering furnaces of different specifications have large differences in size. For example, the length of the car window glass tempering furnace is usually 6-9 meters; the flat glass tempering furnace can even reach more than 30 meters. Therefore, before selecting the model, it is necessary to accurately understand the requirements of the production line for the glass size to avoid the inability to produce normally due to inconsistent sizes.

The bending principle of a flat bending tempering furnace involves heating and shaping glass sheets into curved or bent forms. This process, widely used in manufacturing applications such as automotive and architectural glass, uses controlled heating, bending, and tempering to achieve the desired shape and mechanical properties.

Bending principle of flat bending tempering furnace

1. Heating Phase

The flat glass sheet is placed on rollers and enters the furnace, where it is gradually heated to the softening point (typically around 600-700°C, depending on the glass type).

The heating is carefully controlled to ensure uniform temperature distribution across the glass. Uneven heating can cause distortions or weak points.

2. Bending Process

Once the glass reaches the target temperature and becomes pliable, it is moved to a bending station where the actual shaping occurs. There are two main bending methods in flat tempering furnaces:

Slewing bearings are also called turntable bearings. The main structure includes: inner ring, outer ring, rolling element and rolling element guided cage. It is an important transmission component in mechanical equipment. It is widely used in engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, ship equipment and other industries. Today, the slewing bearing manufacturer will take you to understand the manufacturing process and detailed steps of the slewing bearing.

Slewing bearing manufacturing process

1. Cutting of slewing bearing steel raw materials

The commonly used raw materials for slewing bearings are integrally hardened carbon chromium bearing steel, and the slewing bearing rings are made of surface hardened steel, generally made of 50Mn steel. The cylindrical raw material billets transported back from the steel plant are cut according to the size required for processing the bearings. Generally, carbide saw blades should be used for cutting bearing steel, which has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance.

2. Forging of slewing bearing billets

In the heating furnace, the billets are heated and forged into a round cake shape. The forging link is an important link to ensure the reliability and life of the bearing. After forging, the raw materials form the bearing ring blank. At the same time, the organizational structure of the raw materials becomes more dense and streamlined, which can improve the reliability and service life of the bearing. In addition, the quality of the forging process will directly affect the utilization rate of the raw materials, thereby affecting the production cost.

3. Forging ring of slewing bearing

The steel blank is forged into a ring-shaped steel ring by using a ring rolling machine. Forging can improve the internal organization of steel and improve the strength, plasticity, impact toughness and other mechanical properties of steel.

4. Rough turning

The steel ring after ringing is loaded into the machine tool for rough turning of machining, and various grooves and raceways are turned out. The steel ring is fixed on the gear milling machine and the teeth are cut out. The main purpose is to make the ring after the ring is the same as the shape of the final product, creating conditions for the later grinding machine processing.

5. Quenching (heat treatment) of slewing bearing

After machining, the strength and hardness of the steel are improved through quenching operation, and the wear resistance, fatigue strength and toughness of the metal are improved. The heat treatment process is to treat the bearing rings after forging and turning at high temperature. It directly affects the uniformity of carburization in the bearing rings, can improve the wear resistance and hardness of the bearings, and is also an important link that affects the reliability and life of the bearings.

Four-point contact ball bearings are designed to handle axial loads in both directions and moderate radial loads. They are commonly used in applications requiring combined loading (axial and radial) and where space is limited.

Four-point contact ball bearing installation guide

1. Preparation

Ensure the bearing, housing, and shaft are clean, free from any debris, dirt, or burrs that could affect performance.

Check the parts for any damage or imperfections.

Apply a thin layer of high-quality grease or lubricant to the seating surfaces to ease installation and prevent corrosion.

2. Align the Bearing

Align the bearing with the shaft or housing properly before applying force. Misalignment during installation can lead to excessive load, resulting in premature wear.

Note the direction of loading: four-point contact bearings have a split inner or outer ring, and the load should be directed through the split points.
