Embodiment Construction

[0018] In this embodiment, the smooth surface is T4003 stainless steel with a width of 1130 mm and a thickness of 3.0 mm.

[0019] Step 1: First, check and confirm the channel of the skin-passing unit according to the following equipment flow. It is required that each roll rotates flexibly and has a smooth surface, and each transition plate is lower than the strip surface without deformation.

[0020] Step 2: Confirm the incoming material information including steel quality and specifications when loading, and perform head cutting at the preparation station to ensure that the steel coil can be smoothly loaded onto the uncoiler reel.

[0021] Step 3: After the steel coil enters the reel smoothly, press down the "pressure head roller" to confirm that the steel coil is in the center of the reel, and the inner loose steel coil is first tightened by the reel rotation.

[0022] Step 4: When leveling the first roll, first put in the "upper and lower roller wiper" to wipe the surface ...

Abstract

The invention relates to a flattening production process of stainless steel, comprising an operation process and operation procedures, wherein the operation process comprises the following steps: a crown block lifts a steel coil to a saddle of a walking beam; the walking beam conveys the steel coil to a saddle; a coiling trolley conveys the steel coil to a preparation station; a shearing machine cuts the head of a steel strip; the coiling trolley conveys and measures the steel coil; the steel coil is automatically centered and loaded to an uncoiler through the coiling trolley; the head of thesteel coil is opened through a guide plate scraper knife, and the steel strip is conveyed into a flattening machine through an inlet pinch roll and a straightener; the steel strip is continuously conveyed to a winding drum of a tension coiler so as to complete a head strip penetration process; strip steel is flattened when accelerated to process speed; after the flattening is completed, a coil stripper trolley strips the steel coil from the tension coiler; the coil stripper trolley conveys the steel coil to the saddle of the walking beam; the walking beam conveys the steel coil, meanwhile, the steel coil is respectively weighed, bundled and subjected to number spraying and the steel coil is lifted into a storeroom through the crown block. By means of the flattening production process provided by the invention, the production efficiency is increased from 3 coils/hour to 5.1 coils/hour and the finished product rate is increased from 90 percent to 99.8 percent.

Description

technical field [0001] The invention belongs to the field of stainless steel production technology, is mainly used for T4003 stainless steel, and specifically relates to a smooth production technology of stainless steel. Background technique [0002] The T4003 stainless steel after hot-rolling and annealing is relatively "soft", and there are relatively many iron scales on the surface. During the leveling operation, the surface of the strip steel is prone to surface defects such as scratches and pits, and even waste products. This problem has always plagued the leveling unit. Production not only seriously affects the production efficiency of the skin pass unit, but also reduces the yield of the stainless steel grade. Contents of the invention [0003] The purpose of the present invention is to solve the problems of low production efficiency of T4003 flattening, and defects such as scratches, scratches, and pits on the surface of the strip steel, [0004] The present inven...
