Abstract

An emulsion channeling blocking method for intermediate-roll shifting space involves arranging a spraying baffle (4) on an emulsion spraying beam (2) at an entrance of the intermediate-roll (11,14) of a cold rolling mill. The spraying baffle (4) can move to shield the emulsion spraying beam (2) at the roll shifting space so that the spraying width of the emulsion spraying beam (2) matches with the intermediate-roll (11,14) shifting space and the emulsion is not sprayed to the intermediate-roll (11,14) shifting space. The method enables prevention of emulsion channeling at the intermediate-roll shifting space by changing the spraying area of the spraying beam.

Description

中间辊窜辊空位乳化液窜流的阻断方法  Method for blocking turbulent flow of intermediate roll nipple vacancy emulsion 技术领域Technical field
本发明属于冷轧乳化斑处理技术领域，具体涉及一种冷轧轧制过程中中间辊窜辊空位乳化液窜流的阻断方法，应用于各类冷轧轧机机组。 The invention belongs to the technical field of cold-rolled emulsified plaque treatment, and particularly relates to a method for blocking turbulent flow of an intermediate roller nipple vacancy in a cold rolling process, which is applied to various cold rolling mill units.
背景技术Background technique
冷轧轧制过程中，为了减小被轧带钢的边部减薄，中间辊需要依据带钢宽度进行窜辊，如图1所示。 由于中间辊窜辊时，喷射梁不随中间辊移动，因此，中间辊窜辊后，大量乳化液通过图1中的窜辊区域窜流到对侧带钢上，造成乳化液残留。 In the cold rolling process, in order to reduce the edge thinning of the strip to be rolled, the intermediate roll needs to be rolled according to the width of the strip, as shown in FIG. Since the spray beam does not move with the intermediate roll when the intermediate roll is rolled, a large amount of emulsion flows to the opposite side strip through the roll area in Fig. 1 after the intermediate roll is rolled, causing the emulsion to remain.
技术问题technical problem
本发明的目的在于提供一种中间辊窜辊空位乳化液窜流的阻断方法，该方法可避免乳化液窜流。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for blocking turbulent flow of an intermediate roll roll vacancy emulsion which avoids turbulent flow of the emulsion.
技术解决方案Technical solution
为了实现上述目的，本发明所采用技术方案是：中间辊窜辊空位乳化液窜流的阻断方法，其特征在于：在冷轧轧机的中间辊入口侧的乳化液喷射梁处设置喷射挡板，中间辊窜辊时，喷射挡板移动遮挡住窜辊空位处的乳化液喷射梁，使乳化液喷射梁的喷射宽度与中间辊串辊位置相匹配，在中间辊窜辊空位处不喷射乳化液。 In order to achieve the above object, the technical solution adopted by the present invention is: a method for blocking turbulent flow of an intermediate roll nip vacancy emulsion, characterized in that a spray baffle is arranged at an emulsion spray beam at the inlet side of the intermediate roll of the cold rolling mill. When the intermediate roller rolls, the spray baffle moves to block the emulsion spray beam at the nipple vacancy, so that the spray width of the emulsion spray beam matches the position of the intermediate roll train, and the emulsification is not sprayed at the intermediate roll vacancy liquid.
本发明改变传统解决问题的思路，不采用针对已经窜流到轧辊对侧的乳化液进行封堵处理的方式，而是针对造成中间辊乳化液窜流的原因，即中间辊窜辊后乳化液喷射梁的喷射区域与中间辊位置不一致，在中间辊的窜辊空位处乳化液窜流到对侧带钢表面这一关键原因,采用如图2所示的方式，控制乳化液喷射梁的喷射区域，使乳化液的喷射区域与窜辊后中间辊的位置相匹配，在中间辊窜辊空位上不喷射乳化液，从根本上解决了由于中间辊窜辊空位窜流而造成的乳化斑问题。 The invention changes the conventional solution to the problem, does not adopt the method of blocking the emulsion which has been turbulent to the opposite side of the roll, but the cause of the turbulence of the intermediate roll emulsion, that is, the emulsion after the intermediate roll roll The injection area of the spray beam is inconsistent with the position of the intermediate roll. The key reason for the emulsion to flow to the opposite side of the strip at the idler roll of the intermediate roll is to control the injection of the emulsion spray beam as shown in Figure 2. In the region, the spray area of the emulsion is matched with the position of the intermediate roll after the roll, and the emulsion is not sprayed on the intermediate roll roll, thereby fundamentally solving the problem of emulsification caused by the turbulence of the intermediate roll roll. .
