Thermal safety problem
Mlting glass needs high temperature, so the staff must pay attention to the operation in the furnace. Personal protective equipment such as protective clothing, gloves and masks are essential.
Scald risk
The temperature of the glass belt is still very high after forming, and the operator should be extra careful when touching the glass to prevent scalding.
Mechanical operation risk
There are many mechanical equipment on the glass production line, operators must follow strict operating rules to avoid accidents.
Complex equipment operation
Some equipment may be complex to operate, require professional training for operators, and prohibit unauthorized personnel from operating.
Chemical safety problems
Some harmful substances, such as chemicals, are used in glass production.
Staff must understand the nature of these substances and take appropriate safety measures.
Noise and dust
There may be noise and dust on the production line, which is harmful to the hearing and respiratory system.
Wearing protective earmuffs and masks is essential to the occupational health of workers.
Emergency rescue plan
In the event of an accident, the emergency rescue plan can deal with the situation in a timely manner and reduce the degree of injury.
All staff should be familiar with the emergency rescue plan and conduct regular drills.
Cause of failure
Melting furnace is the key equipment in the process of glass production. The common causes of failure include:
Equipment aging caused by high temperature.
The blockage of the furnace causes the melting material to fail to flow normally.
Unstable flame or fuel supply failure of melting furnace.
Solution
Regular inspection and maintenance of melting furnace, timely replacement of aging parts.
Clean the furnace to prevent blockage.
Monitor flame stability to ensure normal operation of melting furnace.
Cause of failure
Glass ribbon forming machine is a device that forms a flat ribbon of molten glass ribbon. The common causes of failure include:
Wear or loosening of mechanical parts.
Inaccurate temperature control leads to deformation of glass tape.
Uneven thickness of glass strip caused by unbalanced pressing roller.
Solution
Check and replace worn parts regularly to ensure stable operation of machinery.
Accurately control the temperature to avoid the deformation of the glass belt.
Adjust the press roller to ensure the uniform thickness of the glass belt.
Cause of failure
The cooling table is used to lower the temperature of the glass and solidify it. Common causes of failure include:
Failure of cooling fan leads to poor cooling effect.
Blockage or leakage of cooling sprinkler system.
Abnormal cooling process caused by failure of temperature control.
Solution
Check the cooling fan and sprinkler system regularly to ensure smooth flow.
Timely repair of water leakage to ensure good cooling effect.
Monitor the temperature control system, find and solve the abnormal situation in time.
Cause of failure
The cutter is used to cut the glass ribbon to the desired size. common causes of failure include:
Tool wear leads to inaccurate cutting.
Breakage of glass caused by excessive cutting speed.
Glass cracks caused by improper cutting pressure.
Solution
Check and replace worn tools regularly to ensure cutting accuracy.
Control the cutting speed to avoid damaging the glass too fast.
Adjust the cutting pressure to ensure smooth cutting without damage.
Melting furnace
Maintenance method
Regularly check the internal and external conditions of the melting furnace, clean the furnace and vents to ensure smooth ventilation.
Check burner and flame stability, adjust and replace if necessary.
Check the heat insulation material of the melting furnace to ensure good thermal insulation performance.
Replace aging and damaged parts such as refractory bricks and furnace linings regularly.
The furnace is cleaned regularly to prevent melting material from caking and clogging.
Glass ribbon forming machine
Maintenance method
Check the wear of mechanical parts regularly and lubricate and replace them if necessary.
Clean the inside and outside of the machine to prevent dust and debris from accumulating and affecting the operation.
Check the temperature control system regularly to ensure the temperature is stable and avoid the deformation of the glass belt.
Calibrate the press roller regularly to ensure that the thickness of the glass belt is uniform.
Cooling platform
Maintenance method
Check the cooling fan and sprinkler system regularly to ensure good cooling effect.
Clean the inside of the cooling table to prevent blockage and scale accumulation.
Replace the parts of cooling fan and sprinkler system regularly to ensure normal operation.
Check the temperature control system, adjust and repair the fault in time.
Cutting machine
Maintenance method
Check the tool wear regularly and replace it in time to ensure the cutting accuracy.
Lubricate the mechanical parts to ensure the smooth operation of the cutting machine.
Adjust the cutting speed and pressure to avoid glass damage caused by too fast and too large.
Regularly check the safety facilities of the cutting machine to ensure the safety of the operators.
①Method for quality inspection of float glass products
visual inspection
Inspect the glass surface visually for bubbles, scratches, spots or other defects.
dimension check
Measure the length, width and thickness of the glass to ensure that the product size meets the requirements.
flatness check
Check the flatness of the glass with a ruler or flat object to prevent the product from bending or warping.
optical performance check
The optical quality of the product is ensured by testing the optical properties such as transmission, reflection and refraction of light.
② The method of distinguishing between high and low quality production lines
technical level of equipment
High-quality production lines usually use advanced equipment and technology, which can control the production process more accurately and improve the consistency and stability of products.
raw material selection
High-quality production lines use high-quality raw materials to ensure that the chemical composition and physical properties of the products can meet the requirements of the standard.
degree of automation
High-quality production lines usually have a high degree of automation, reducing the impact of human factors on product quality.
production process
The high-quality production line adopts a strict production process to ensure that every link is carefully controlled and inspected.
quality certification
High-quality production lines often pass ISO9001 and other international quality certification, indicating that their products meet international standards.
