Embodiment

[0015] What the present embodiment coils is the stainless steel strip steel for railway vehicle of label 1.4003, wide 1.5m, thick 4mm. The 2250 hot rolling mill produced by SMS company is used.

[0016] When the coiler is used to coil the strip steel, before the head of the strip steel exits the final stand of the finishing mill, the automatic control program will close the cooling water of the heat output roller table from the first section to the fourth section, when the head of the strip steel When the first section advances to the third section of the heat output roller table, the cooling water of the 5th to 10th section of the heat output roller table is turned off. When the head of the strip enters the coiler and is wound on the reel, the reel of the coiler After the strip is tensioned, the automatic control program turns on the cooling water of all the 1st to 10th heat output roller tables.

Abstract

The present invention relates to a method of reeling the stainless strip steel for the railway vehicle, comprising the following steps in sequence: I, before the head of the stainless strip steel is moved out of the tail stand of a fine rolling machine, the stainless strip steel is conveyed into a reeling machine through a heat output roller way; II, the stainless strip steel is reeled on a reeling cylinder by the rotating reeling machine; and III, the tensile force is formed between the reeling cylinder of the reeling machine and the working roll of the tail stand of the fine rolling machine, and the subsequent stainless strip steel is rolled out of the fine rolling machine under the tensile force and is conveyed into the reeling machine through the heat output roller way. The method of reeling the stainless strip steel for the railway vehicle is characterize in that when the stainless strip steel is reeled, the cooling water at the front one second section of the heat output roller way is turned off after the head of the stainless strip steel is moved out of the tail stand of the fine rolling machine, the cooling water at the rear one second section of the heat output roller way is turned off after the head of the stainless strip steel is moved to the four tenth section of the heat output roller way, and the cooling water of the heat output roller way is turned on after the head of the stainless strip steel is moved into the reeling machine and is wound on the reeling cylinder. The method of reeling the stainless strip steel for the railway vehicle can prevent the surface of the stainless strip steel from being worn to have the defect.

Description

technical field [0001] The invention relates to a method for coiling stainless steel strips for railway vehicles. Background technique [0002] When the existing stainless steel strips for railway vehicles are coiled, the hot-rolled stainless steel strips shrink and deform more than other stainless steels after being cooled by water on the layer cooling roller table. After being cooled by the cooling water of the roller table, especially when the strip head When the head does not enter the coiler and the coiler does not build up tension, a section within 80m of the head of the strip will appear red and black with uneven heat and cold, showing a plate shape of local broken waves. After entering the coiler, it will The uneven friction on the surface of the strip steel will cause surface defects and become waste products, resulting in waste. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing stainless steel strip coiling ...
