Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aluminium rolling mill, concretely relates to an automatic fire extinguishing device of kerosene spraying system of aluminium rolling mill. BACKGROUND

[0002] Aluminium rolling mill is a kind of equipment for rolling aluminium ingot or aluminium slab into aluminium plate, aluminium strip and other aluminium materials. It is mainly composed of rolls, roll bearings, racks, screwdown devices and other components. Roll is the key part, and through the rotation of two rolls, aluminium material is deformed between them under pressure. According to the number and arrangement of rolls, aluminium rolling mill can be divided into two-roll rolling mill, four-roll rolling mill and the like. For example, four-roll rolling mill can better control the thickness accuracy and flatness of aluminium plate, and is suitable for the production with high product accuracy requirement.

[0003] The existing kerosene spraying system is often used on aluminium rolling mill equipment. The kerosene spraying system of aluminium rolling mill mainly increases the friction of rolls, which is beneficial to the biting of aluminium alloy ingot. When the biting efficiency cannot be effectively improved by optimizing pass table, some kerosene can be sprayed between the rolls to increase the friction of rolls and improve the biting efficiency of rolling mill. At the same time, a large amount of heat is generated between the rolls and aluminium materials due to friction during the aluminium rolling process. The kerosene spraying can take away the heat to prevent the damage of rolls and aluminium materials due to overheating or affect the quality of aluminium materials. For example, continuous high temperature may change the surface hardness and other properties of aluminium materials, and kerosene can effectively alleviate this problem. In terms of lubrication, kerosene can reduce the friction between rolls and aluminium materials. This helps the smooth passing of aluminium materials through the rolls, makes the rolling process more stable, and reduces the wear degree of rolls to prolong the service life of rolls.

[0004] The kerosene spraying system of aluminium rolling mill mainly includes kerosene tank, oil pump, spray head, electric control valve and pipeline system and the like. The kerosene tank is used for storing kerosene, the oil pump delivers kerosene to the spray head, the spray head is installed at a proper position of the rolling mill to ensure that kerosene can be uniformly sprayed on the rolls and aluminium materials. The kerosene in the kerosene tank belongs to flammable and explosive device, so the safety management of kerosene spraying system is very important on the rolling mill site. Usually, the kerosene tank is installed in an open space far away from the office of personnel. When the aluminium rolling mill catches fire, the staff needs to find and take out the fire extinguishing equipment. In this process, the fire may expand and the aluminium rolling mill cannot be extinguished in time. At the same time, the aluminium rolling mill is usually used in the equipment plant house, and the height between the roof and the ground of the plant house is high. When the aluminium rolling mill on the ground catches fire, it is difficult to accurately cover the fire source by spraying fire extinguishing agent from the roof, which is not conducive to effective fire extinguishing.
