What kind of dust is the dust in the foundry, and how much damage does the dust in the foundry do to

Foundry dust, usually a metal solution poured into a sand mold, contains a large amount of silica.

and metal oxidized dust, if this environment is not properly breathed, it is very susceptible to casters' pneumoconiosis. For the sake of your body, it is recommended to choose a dust mask scientifically.

The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.

2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions.

Masks with high rigidity are prone to facial indentation.

4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

5. The mask covers the mouth and nose, covering the mouth, nose and jaw.

2 types, the latter is recommended, which is relatively comfortable.

6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

In China's industrial production, mechanical casting is used in many industries, including motor production, machine tool production, heavy ore production, etc., and casting, grinding and vibration shakeout and other types of work will apply casting technology. Generally speaking, the production process of the foundry workshop is mainly the following links: sand grinding.

This link is mainly to make forming sand by crushing the materials used in the production of clay or coke powder; Sculpt. After the sand grinding process, the production personnel need to model, combine the specific requirements and standard specifications of the products to be cast, make wooden molds, and put the molding sand in the sand box for production. At the same time, the production personnel also need to add iron and other materials to the cupola furnace to melt it into molten iron; The production staff needs to pour molten iron into the molding sand, and open the sand box to allow the molding sand to cool down completely, and carry out simple casting treatment; The production personnel need to thoroughly remove the burrs or sand in the casting, and the old sand can be used for the next production.

Among the above four production links, the first.

The first, second and fourth links are prone to dust, and the dust generated will also be different due to different sand-based production methods and different specific varieties of castings. In the first link above, the dust mainly produced is silica dust, while the second link is prone to produce dust of other components. Relevant studies have shown that 1t of molten iron will produce dust ranging from 6kg to 15kg, and in the production process of non-melting castings, about 50kg of dust will be generated for every 1t casting.

Through such data, it can also be seen that in the production process of the mechanical casting workshop, the concentration of dust is often higher, which will bring more serious pollution and harm, so it is necessary to carry out scientific and effective prevention and control of dust pollution.

Hello dear, glad to answer for you. Foundry dust can cause lung diseases, blood diseases, etc.

Dust refers to the particles with a diameter greater than microns in the air of the air, which can be used in daily life, but the more common dust is the dust generated by industrial production, which is extremely harmful to people's eyes. Inhalation of dust can cause pneumonia, silicosis, etc. Especially for people who work in chemical plants, frequent inhalation of dust may also cause serious diseases such as chronic obstructive pulmonary disease and lung cancer.

Frequent inhalation of dust may also cause contaminants to dissolve into the bloodstream, causing blood disorders or blood poisoning. In addition to causing disease, dust is also a major safety hazard. Because dust is very easy to ignite, when the volume expands when exposed to an open flame, dust will also occur.

Therefore, for the sake of health and life safety, you should stay away from dust, if you have long-term exposure to dust and have respiratory system or other system discomfort, please go to a regular hospital for examination in time to avoid delaying the course of the disease.

Hello dear! Casting workers' pneumoconiosis refers to the sand turning in the casting operation, and the long-term inhalation of dust with complex composition and low free silica content, such as clay, graphite, mildew, limestone and talc and other mixed dusts, is mainly composed of nodular or dust spots accompanied by pulmonary interstitial fibrosis damage. The onset of the disease is slow, and there are many unconscious symptoms in the early stage, chest tightness, chest pain, cough, sputum production, shortness of breath and other symptoms can appear with the progression of the lesion, and the lung function is mostly normal in the early stage of the lesion, and then gradually appear obstructive or obstructive-based ventilatory dysfunction, and the ventilatory dysfunction of patients without bronchial and lung diseases is generally mild.

Due to the large amount of smoke and dust in the air during the operation, poor labor protection and other reasons, it is combined with chronic bronchitis and emphysema.

Dear, I'm sorry to keep you waiting, I'm glad I can answer for you: Foundry dust removal ash is one of the solid wastes discharged in the production process, mainly in ore smelting, molten metal pouring and other process links of industrial dust, flue gas, exhaust gas and other pollutants after being filtered by dust removal equipment. The main components of dust removal ash are substances such as oxides, silicates, and heavy metal ions.

Dust removal ash has a wide range of uses, and can be used as building materials, fertilizer raw materials, ceramic raw materials, etc. Specifically:1

Building materials: Dust removal ash is used in the production of concrete, blocks, bricks and other building materials, which can improve the strength and durability of the material. 2.

The dust removal ash of the foundry usually refers to the ash obtained by the foundry sand, foundry waste and other substances produced in the casting production process after dust removal treatment.

Does the foundry produce flammable and explosive dust, no, there are mainly these hazards; Casting is one of the most important and basic processes in the machinery manufacturing industry, and the most basic method is sand casting, which includes modeling, alloy smelting, pouring, casting sand removal, etc.; Its main occupational hazard factor is dust, which can exist in many links of casting, including crushing, sand screening, sand mixing, modeling, sand removal, sand cleaning, sandblasting, etc., and long-term inhalation of casting dust can cause caster pneumoconiosis. Smelting, pouring and hot castings are all heat sources, smelters and casters are affected by high temperatures, strong thermal radiation, and the smelting and casting process can also produce carbon monoxide, sulfur dioxide and metal fumes. In addition, the mechanical equipment used in the process of compaction, compaction, sand removal and cleaning can also generate noise and vibration.

Therefore, casting should first try to choose low free silica content of molding sand, and reduce manual modeling and sand cleaning operations, especially the sand cleaning operation is the highest dust concentration in the casting stool land, should be given key protection, such as the installation of high-power ventilation dust removal system, the implementation of spray wet operation, in order to reduce the dust concentration in the workplace, and wear dust masks that meet the relevant national standards, in accordance with the relevant national regulations, do a good job of occupational health inspection of workers for rough inspection. Hope it helps.
