Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , figure 2 In the method for reducing the hydrogen content of steel slabs shown, the steel slabs 1 are stacked layer by layer from bottom to top, wherein the steel slabs 1 of the same layer are arranged parallel to each other, and the upper and lower adjacent two layers of steel slabs 1 are arranged vertically to each other. There are gaps between adjacent billets 1 of the same layer.

[0018] In actual operation, the stacks are required to be neat, stable, and in the shape of a well, and skewing and unevenness are strictly prohibited. The number of stacking layers for each stack is strictly regulated according to the section and the height of the factory building. In order to facilitate subsequent management and ensure product quality, it is preferable to make relevant records when billet 1 is off-line and stacked, and record information suc...

Abstract

The invention relates to the field of steel blank treatment processes, in particular to a method for reducing the hydrogen content of steel blanks; the method preferably solves the control demands ofthe hydrogen content in steel and the hydrogen content control problem; the steel blanks are stacked layer by layer from bottom to top; the steel blanks on the same layer are arranged in parallel; thesteel blanks on the upper and lower adjacent layers are perpendicularly arranged; and gaps are formed between the adjacent steel blanks on the same layer. The method skillfully designs the steel blanks in the layer-by-layer stacking mode; and under the condition of not changing traditional equipment and conditions, hydrogen of casting blanks is preferably emitted within a certain temperature andtime range by using the hydrogen emission principle in the casting blank stacking mode of the steel blanks to achieve the purpose of reducing the hydrogen content in the casting blanks. The method issimple, easy to operate and lower in investment, and preferably solves the control difficulty of the hydrogen content in the steel blanks. The method is particularly suitable for processes of reducingthe hydrogen contents in the steel blanks.

Description

technical field [0001] The invention relates to the field of iron and steel slab processing technology, in particular to a method for reducing the hydrogen content of steel slabs. Background technique [0002] The hydrogen in the steel slab has a great influence on the quality and performance of the final rolled product. In order to ensure the performance of the steel, it is necessary to strictly control the hydrogen content in the steel. In the current control method for removing hydrogen content in steel, the method of molten steel refining (RH treatment) and strengthening the management of raw and auxiliary materials are mainly used to control the hydrogen content in molten steel. However, due to the different equipment and suppliers of various manufacturers, Cause the final control level of hydrogen content to be different. The existing processing methods are as follows: [0003] 1. CN107012298A A method for controlling the hydrogen content in rails (public date: 2017....
