Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list
In particular the mill scale can be classified as follows:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00
Steel products refer to solid straight steel products with a certain section shape and size, including wire, profile and plate, which are formed by plastic processing except pipes. It can be divided into hot rolling, cold bending, cold rolling, cold drawing, extrusion, forging, hot bending, welding and special rolling according to the production method. It can be divided into railway, shipbuilding, mining, structure and construction according to its use. According to the material can be divided into carbon steel, alloy steel and stainless steel. At the same time, these steel products can be reprocessed to form semi-finished products or finished products to meet special requirements. We can according to the customer's different needs, according to the drawings or samples for reprocessing production.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Mace
Botanical: Myristica fragrans
Family: N.O. Myristicaceae
Hindi Name: Mace - Javitri
General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia.
Geographical Sources
The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana
Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed.
Varieties -> Whole nutmegs are grouped under three broad quality classifications:
1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes.
2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%.
3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%.
Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter.
Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
Marigolds were first discovered by the Portuguese in Central America in the 16th century.
Marigolds are hardy, annual plants and are great plants for cheering up any garden. Broadly, there are two genuses which are referred to by the common name, Marigolds viz., Tagetes and Celandula. Tagetes includes African Marigolds and French Marigolds. Celandula includes Pot Marigolds.
Kingdom : Plantae
Division : Magnoliophyta
Class : Magnoliopsida
Order : Asterales
Family : Asteraceae
Genus : Tagetes, Calendula
Marigolds come in different colors, yellow and orange being the most common. Most of the marigolds have strong, pungent odor and have has great value in cosmetic treatment. There are many varieties of Marigolds available today. Some of the major Marigold varieties are listed below:
African or American Marigolds (Tagetes erecta): These marigolds are tall, erect-growing plants up to three feet in height. The flowers are globe-shaped and large. Flowers may measure up to 5 inches across. African Marigolds are very good bedding plants. These flowers are yellow to orange and do not include red colored Marigolds. The Africans take longer to reach flowering stage than the French type.
French Marigolds (Tagetes patula): Marigold cultivars in this group grow 5 inches to 18 inches high. Flower colors are red, orange and yellow. Red and orange bicolor patterns are also found. Flowers are smaller, (2 inches across). French Marigolds are ideal for edging flowerbeds and in mass plantings. They also do well in containers and window boxes.
Signet Marigolds (T. signata 'pumila'): The signet Marigolds produce compact plants with finely divided, lacy foliage and clusters of small, single flowers. They have yellow to orange colored, edible flowers.The flowers of signet marigolds have a spicy tarragon flavor. The foliage has a pleasant lemon fragrance. Signet Marigolds are excellent plants for edging beds and in window boxes.
Mule Marigolds: These marigolds are the sterile hybrids of tall African and dwarf French marigolds, hence known as mule Marigolds. Most triploid cultivars grow from 12 to 18 inches high. Though they have the combined qualities of their parents, their rate of germination is low.
Marigold (Calendula) is an extremely effective herb for the treatment of skin problems and can be used wherever there is inflammation of the skin, whether due to infection or physical damage; for example, crural ulceration, varicose veins, haemorrhoids, anal fissures, mastitis, sebaceous cysts, impetigo or other inflamed cutaneous lesions.
As an ointment, Marigold (Calendula) is an excellent cosmetic remedy for repairing minor damage to the skin such as subdermal broken capillaries or sunburn. The sap from the stem is reputed to remove warts, corns and calluses.
