Production precautions for rock wool production line

1、 Core precautions for production safety

Personal protection must be in place: Rock wool production generates mineral fiber dust, and all frontline operators must wear dust masks, stab resistant gloves, long sleeved protective clothing throughout the process. Direct skin contact with rock wool is strictly prohibited; Fiber particles with a diameter less than 3 microns can penetrate ordinary masks. It is recommended to use dust masks of KN95 or higher level. Regular respiratory examinations are required for long-term operations.

Strictly follow the equipment operation specifications: wiping, cleaning, and maintenance operations are strictly prohibited during equipment operation. Such operations must be stopped, the power must be cut off, and warning signs must be hung first; Before starting up, it is necessary to thoroughly check the operating status and safety protection devices of the equipment, and confirm that there are no abnormalities before starting.

Environmental risk prevention: In summer, the ambient temperature around the furnace often exceeds 50 ℃, and it is necessary to arrange job rotation reasonably to avoid heat stroke caused by long-term operation; The noise level of equipment such as crushers can reach 100 decibels, and it is necessary to wear soundproof earplugs. Long term exposure can cause irreversible hearing damage.

Unslackening in hazard investigation: Management personnel must conduct three safety inspections before, during, and after work every day, and inspect the electrical, fire, and ventilation systems of the entire production line every week. If any hazards are found, the responsible person must be identified and rectified within a specified period of time. Major hazards must be supervised and rectified by hanging signs.

2、 Product quality control precautions

Strict inspection of raw materials: Different raw materials must be screened according to particle size (basalt requires 80-120mm, dolomite requires 40-60mm, and the proportion of unqualified particle size cannot exceed 10%). The chemical composition of incoming raw materials must be tested, and unqualified raw materials are strictly prohibited from being put into use; Raw materials should be classified and stored with moisture-proof measures to avoid deterioration and affect the quality of finished products.

Precise control of process parameters: Strictly control the raw material ratio and acidity coefficient (the acidity coefficient of rock wool should be maintained at 1.4~2.0 to ensure chemical stability), the melting temperature of the blast furnace should be stable and meet the standard, and the centrifuge speed and air pressure should be adjusted according to the melt state during the fiber forming stage to ensure uniform fiber diameter.

Finished product inspection standard release: Each batch of finished products must undergo appearance, thermal conductivity, strength and other indicators testing. Only after passing the testing and signing confirmation can they be released; Unqualified products must be isolated and labeled, and production can only be resumed after analyzing the reasons and rectifying them.

3、 Equipment maintenance precautions ?

During the production process, close attention should be paid to the equipment status. If abnormal noise, vibration, or odor occurs, the machine must be immediately shut down for troubleshooting before resuming production to avoid equipment damage caused by faulty operation.

Lubricate and replace vulnerable parts of the equipment on a periodic basis, keep maintenance records, and regularly calibrate the accuracy of core equipment such as furnaces and centrifuges to ensure stable production processes.

When stopping production for maintenance, the main power supply should be cut off, and on-site protection should be taken to avoid safety accidents caused by accidental start-up.
