The utility model is characterized in that the outer roller is welded with a left and a right flange plates through copper roller rings to form a roller body having a hollow structure; the inner roller formed by welding of a steel roller ring and a ribbed slab; the inner roller is matched in a cavity of the outer roller and divides the cavity into a water inlet cavity and a water outlet cavity; a left and a right shafts are respectively connected to the outer sides of the left and the right flange plates; one of the left and the right shafts is a through shaft, and a through cavity of the through shaft is a passage for the water outlet cavity and the exterior of the roller. The water inlet pipe is threaded through the through shaft from outside and is extended to the water inlet cavity of the outer roller. At least one of the inner surface of a copper roller ring and the outer surface of a steel roller ring is uniformly distributed with a water excess groove. The utility model adopts copper and steel combined material and has the advantages of low manufacturing technology requirements, low cost and good integral strength.
Description
Affiliated technical field
The utility model relates to a kind of critical piece of sheet continuous casting and rolling machine, particularly Quench crystallization roller, and the utility model is suitable for rolling stainless steel plate strip.
Background technology
Sheet continuous casting and rolling has efficiently, low consumption, characteristic cheaply, is each developed country of the world new technology and new technology of falling over each other to develop in recent years.Quench crystallization roller is one of critical component in the sheet continuous casting and rolling plant equipment, its structure is mainly by inside and outside roller, formations such as left and right axle and water inlet pipe, the Quench crystallization roller of developed country mostly adopts copper-chromium-Zirconium alloy material manufacturing, it has characteristics such as the heat conduction is fast, heat-resisting, wear-resisting, but its bulk strength haves much room for improvement, manufacturing technology requires height, costs an arm and a leg.The job requirement of Quench crystallization roller be exactly will be in a short period of time with the roller surface up to 1500 ℃ of rapid Quench to 400 of temperature～500 ℃ of temperature ranges, its caloric requirement was taken out of by the flowing carrier of this roller inner cooling system in moment.Therefore the structure of described Quench crystallization roller and design of Cooling System in the roller and material thereof selects the success or failure that directly have influence on casting and rolling process, the quality of product quality and the height of operating efficiency for use.At present, nearly all be to rely on external import at the Quench crystallization roller of the widely used sheet continuous casting and rolling machine of China's metallurgy industry, and the price of pair of rolls is up to more than 100,000 dollars.In order to change this passive present situation, the inventor is through for many years practical exploration, and autonomous Design is developed following Quench crystallization roller technological achievement.
Summary of the invention
In order to overcome the problem that the manufacturing technology requirement is high, price is expensive that existing Quench crystallization roller exists, the utility model provides a kind of Quench crystallization roller of improved sheet continuous casting and rolling machine, this roll structure design is fit to adopt the compound material of using of copper-steel, and its manufacturing technology is less demanding, price is low, good integral strength.
The technical scheme that the utility model addresses the above problem employing is: a kind of Quench crystallization roller of sheet continuous casting and rolling machine, by outer roller, interior roller, left side axle, right axle and water inlet pipe constitute, it is characterized in that outer roller is by a copper roller circle and a left side, right ring flange welding constitutes the hollow structure roll body, interior roller is made of steel rider circle and gusset welding, interior roller is engaged in the cavity of outer roller and cavity and is separated into intake antrum and water chamber, a left side, right axle is connected to a left side, the right ring flange outside, a left side, right axle has one to be logical axle, its logical chambers of the heart is outer roller water chamber and the outer passage of roller, water inlet pipe passes logical axle from the outside and extends to the outer roller intake antrum, and the inner surface of copper roller circle and the outer surface of steel rider circle have one at least, be evenly distributed with water groove above it.
The beneficial effects of the utility model are: owing to adopted the compound Quench crystallization roll structure of making of material of copper-steel, it is not very high that its manufacturing technology requires, low cost of manufacture, as long as facts have proved the compound cooling system that enough flows are arranged with the Quench crystallization roller of material of copper-steel, it is the advanced level that can reach the Quench crystallization roller of the copper-chromium-Zirconium alloy material that occurs in the international market at present, not only the heat conduction is fast, heat-resisting, wear-resisting, and bulk strength is better, thus the utility model be a kind of be the satisfactory texture that economy is suitable for again.As a Quench crystallization roller of the present utility model, the external diameter of its outer roller is about the 550mm width and is about 310mm, adopts most economical normal-temperature water cooling method, flow velocity 5～6m/min in realizing roller, during flow 30T/h, the design of Cooling System in the roller just can meet technological requirement of the present utility model.
