Abstract
The utility model relates to a scale removing nozzle, which belongs to a scale removing nozzle using high-pressure water in a hot-rolling steel plate appliance. The front section of the inner hole of a nozzle body forms a forwards concave cone shape, and the inner of the nozzle body is assembled with a nozzle head, the outer circle surface of which is cone-shaped. The middle back section of the inner hole of the nozzle body is isodiametric, and the inner of the nozzle body is assembled with a pressurized ring, the inside diameter of which is cone-shaped. The utility model has the advantages that a fault that the nozzle head is emerged from the inner hole of the nozzle body is eliminated, the product quality and the production safety can be guaranteed better, and the utility model has simple structure.
Description
The utility model relates to the high-pressure water descaling nozzle in a kind of steel rolling equipment.
In hot rolled steel plate is produced, for guaranteeing product surface quality, the stove that needs to remove steel slab surface is given birth to iron scale and regenerating oxidation iron sheet, adopting high pressure water descaling device to carry out de-scaling now handles, and the descaling jet in this device is the critical component that influences the de-scaling quality, the descaling jet of the eighties Anshan iron and steel plant in mid-term design and research institute and Shenyang City's light equipment factory joint research and development, scale removal effect is good, it is made up of nozzle body and nozzle head, nozzle body has an equal diameter endoporus, the external peripheral surface of nozzle head coats copper sheet, behind the nozzle body endoporus of packing into, and the welding of heating.But when work water pressure is too high, nozzle head and nozzle body takes place sometimes break away from and the situation of high speed ejaculation, nozzle head bump steel plate damages surface of steel plate, makes product rejection, causes certain loss.
The purpose of this utility model is at the problems referred to above, and a kind of improved descaling jet is provided, and this nozzle is eliminated the fault that nozzle head is deviate from from the nozzle body endoporus, guarantees production safety and product quality, and simple and reasonable.
The purpose of this utility model is achieved in that the leading portion at the nozzle body endoporus is receive in forward cone-shaped, and assembling outer round surface is pyramidal nozzle head in it; The posterior segment of nozzle body endoporus is isometrical, and assembling internal diameter is pyramidal supercharging ring in it.
The utility model has the advantages that: eliminate the fault that nozzle head is deviate from from the nozzle body endoporus, guaranteed product quality and production safety, and simple and reasonable.
Below in conjunction with accompanying drawing the utility model embodiment is described.
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
See Fig. 1, the utility model embodiment 1 structure is the structure of assembling with no filtering nozzle joint: the endoporus leading portion of nozzle body 1 is interior forward receive cone-shaped, the nozzle head 3 of packing on this section, and its outer round surface is cone-shaped; Endoporus posterior segment at nozzle body 1 is isometrical, and this section goes up the tight fit supercharging ring 2 of packing into, receives cone-shaped in its internal diameter is forward.4 expression nozzle connections are threaded togather with the utility model among the figure.
See Fig. 2, the utility model embodiment 2 structures are and the structure that the assembling of filtering nozzle joint is arranged: with above-mentioned difference be, supercharging ring 2 is short, pack into the endoporus stage casing of nozzle body 1 of its tight fit, its endoporus back segment has internal thread, internal thread segment is screwed with the filter of nozzle connection 4 and is connected, and other is identical with embodiment 1.
Claims (1)
1, a kind of descaling jet comprises nozzle body, nozzle head, it is characterized in that: the leading portion of nozzle body endoporus is interior forward receive cone-shaped, and assembling outer round surface is pyramidal nozzle head in it; The posterior segment of nozzle body endoporus is isometrical, and assembling internal diameter is pyramidal supercharging ring in it.
