Embodiment Construction

[0019] attached figure 1 It is a specific embodiment of the present invention. The invention is a production process of thick-gauge hot-rolled pickling plate, which includes the following steps:

[0020] 1) A coil preparation station is arranged behind the feeding device to form the coil feeding and pre-coil preparation part of the push-pull pickling unit; the feeding device is mainly responsible for the feeding of hot-rolled raw materials The car lifts the raw material coils to the feeding device, and transports the raw material coils to the weighing device through the walking transport beam. After weighing, the coils are transported to the unbundling position by the coil shuttle car to unbundle; The main function of the coil preparation station is to prepare the uncoiler 1 for the uncoiler 1 by straightening the tape head and cutting off the unsuitable part of the tape head;

[0021] 2) The feeding device and the center line of the steel coil preparation station are vertic...

Abstract

The invention belongs to the technical field of hot-rolled pickled plates, and particularly relates to a production process for a thick-specification hot-rolled pickled plate. The production process for the thick-specification hot-rolled pickled plate comprises the following steps of: arranging a steel coil preparatory station behind a loading device to form a steel coil loading and strip coil previous preparation part of a push-pull type pickling unit, wherein the loading device is mainly responsible for loading work of hot-rolled raw material strip coils, and mainly comprises a workshop overhead crane for hoisting and putting the raw material strip coils onto the loading device, and a strip coil shuttle car is used for transporting the strip coils to strip binding positions to start strip binding after the raw material strip coils are transported to a weighing device through a step transportation beam to weigh; and the steel coil preparatory station is mainly used for straightening strip heads and cutting off unqualified parts of the strip heads for the raw material strip coils to prepare for uncoiling of an uncoiling machine. The production process has the beneficial effects of expanding the variety and the specification production range of products, and improving plate shape and surface smoothness of the hot-rolled picked strip steel; and the produced product is wide in variety and specification range and is good in quality.

Description

technical field [0001] The invention belongs to the technical field of grid hot-rolled pickled plates, and in particular relates to a production process of thick-gauge hot-rolled pickled plates. Background technique [0002] At present, the push-pull pickling unit used by major domestic manufacturers of hot-rolled pickling sheets can produce main varieties and specifications limited to less than 6mm in thickness and less than 500Mpa in tensile strength, and because there is no tempering unit, it is impossible to improve the plate of hot-rolled raw materials shape defects. The hot-rolled pickling plates with a thickness of more than 6mm and a tensile strength of more than 500Mpa are mainly imported. Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a thick-gauge hot-rolled pickling method that increases the strength and motor capacity of the equipment, and smoothes the hot-rolled pickled plate after pick...
