Device for measuring zinc-pot-bottom-slag height

Abstract

The invention discloses a device for measuring the zinc-pot-bottom-slag height. The device for measuring the zinc-pot-bottom-slag height comprises a base (1); a pressure measurement rod (2) capable ofperpendicularly moving up and down and a perpendicular-moving driving mechanism for driving the pressure measurement rod (2) to move up and down are arranged on the base (1) in the vertical direction; a pressure-measurement-rod end head (3) is arranged at the lower end of the pressure measurement rod (2), and a pressure sensor (4) for detecting the pressing reactive force of the pressure measurement rod (2) is connected to the pressure measurement rod (2). According to the device, regular, multi-point and automatic measurement of the zinc-pot-bottom-slag height can be achieved, height changesof zinc-pot bottom slag are effectively tracked, control over the zinc-pot bottom slag can be better guided accordingly, and the influence of the zinc-pot bottom slag on the product coating quality and the production efficiency is eliminated; in addition, the labor intensity and operation risk of manual measurement can be reduced.

Description

technical field [0001] The invention belongs to the technical field of measurement, and specifically relates to a high-performance coating product production unit applied to alloyed hot-dip galvanized products (GA), hot-dip galvanized products (GL) and hot-dipped aluminum-silicon products (AS) Zinc pan bottom slag height measuring device. Background technique [0002] At present, due to their excellent performance, alloyed hot-dip galvanized products (GA), hot-dip galvanized products (GL) and hot-dipped aluminum-silicon products (AS) have developed very rapidly in recent years, but zinc pots are common in the above-mentioned production lines. The problem of bottom dross accumulation, when the accumulation of bottom dross in the zinc pot exceeds a certain range, the zinc dross will be involved in the strip steel coating due to the agitation of the bottom dross due to the operation of the strip steel (see figure 1 ), thereby affecting the quality of the product coating. In ad...

AI Technical Summary

Problems solved by technology

[0003] At present, iron and steel enterprises at home and abroad do not have a relatively mature solution to completely eliminate the bottom slag of zinc pots. They mainly use the method of measuring the height of the bottom slag and removing the slag regularly to control the height of the bottom slag within a reasonable range and reduce the impact of the bottom slag on the quality and quality of the product coating. Impact on production efficiency

The height of the bottom slag is generally held by the operator such as figure 2 The method shown with simple tools is used to measure. Since the temperature of the zinc liquid is generally controlled at 450-630°C, manual measurement of the bottom slag height under such operating environment conditions is not only dangerous and labor-intensive, but also difficult to meet the requirements for measurement accuracy.
