Controlled rolling equipment for Q195 hot-rolled coiled plates

Abstract

The invention discloses controlled rolling equipment for Q195 hot-rolled coiled plates, and relates to the technical field of controlled rolling for the Q195 coiled plates. The equipment comprises a supporting frame, wherein mandrels are rotationally connected to the inner side of the lower end of the supporting frame, a rolling wheel is fixedly connected to one end of each mandrel, a to-be-processed plate is in contact connection with the upper surface of the rolling wheel, a first guide pipe is fixedly mounted on the inner side of the upper end of the supporting frame, spray nozzles are fixedly mounted on the inner side of the lower end of the first guide pipe, a second guide pipe is fixedly mounted at the lower end of the supporting frame, an air outlet is formed in the upper end of the second guide pipe, and a collecting cover is fixedly mounted at the upper end of the supporting frame. The equipment has beneficial effects as follows: the spray nozzles spray water to cool the plate, produced water vapor can be absorbed by the collecting cover, line of sight is prevented from being affected by the water vapor, air motion at the bottom of the plate is accelerated, the cooling effect of the plate is better, and the to-be-processed plate is limited by a limit plate and is prevented from deflecting in a conveying process.

Description

technical field [0001] The invention relates to the technical field of controlled rolling of Q195 coils, in particular to a controlled rolling equipment for Q195 hot rolled coils. Background technique [0002] Controlled rolling is to control the change law of austenite structure and the structure of phase transformation products by controlling the heating temperature, rolling temperature, deformation system and other process parameters, so as to achieve the purpose of refining the structure and improving the strength and toughness. [0003] The current Q195 hot-rolled coil controlled rolling equipment mostly uses water spraying to reduce the temperature of the plate when cooling down, but a large amount of water vapor will be generated when spraying water, and the presence of water vapor will affect the sight of observers, which is easy It causes safety hazards, and the way of spraying water is mostly to cool down on one side, which is not enough for the cooling range under...

Problems solved by technology

[0004] The purpose of the present invention is to provide a Q195 hot-rolled coil control rolling equipment to solve the problem that a large amount of water vapor will be generated when spraying water to control the temperature. Most of the way is to cool down on one side, and the problem of insufficient cooling range under the plate
