Abstract

The invention discloses a zinc liquid storage tank for hot galvanizing production line and a method for storing zinc liquid by using the same. The zinc liquid storage tank comprises a zinc storage tank and a PLC (Programmable Logic Controller) temperature collecting and controlling system, wherein the lower part of a tank body inner container of the zinc liquid storage tank is provided with a brick set body; the periphery of the sides is provided with a tank wall insulation cushion; the upper part is provided with a tank body insulation cover; the tank body inner container is made from a steel plate which is specially used for hot galvanizing zinc pot and has the thickness of 20-50mm, and the steel plate specially used for hot galvanizing zinc pot is XG08 type steel plate, wherein C in the chemical component of the steel plate is less than 0.08 percent by weight, and Si is less than or equal to 0.03 percent by weight. The method for storing zinc liquid comprises the following steps of: measuring zinc liquid temperature through thermocouple inserted in the zinc liquid in the tank; and simultaneously controlling a plurality of zinc storage tank body heating elements by a PLC temperature collecting module and a relay assembly to heat and insulate the zinc liquid in the tank. The zinc liquid is stored by using the zinc liquid storage tank, the oxidation loss of the zinc is reduced and the stop production time is shortened.

Description

technical field [0001] The invention relates to a liquid zinc storage tank used in a hot-dip galvanizing production line and a method for storing the liquid zinc; the liquid zinc storage tank is used for the liquid zinc in the zinc pot when the batch hot-dip galvanizing production needs to shut down the furnace for maintenance or replace the zinc pot store. Background technique [0002] During the production work of the hot-dip galvanizing production line, the iron zinc pot needs to be repaired due to corrosion, or the zinc pot needs to be replaced when the zinc pot is close to the service life, which will inevitably encounter the zinc liquid treatment in the zinc pot question. With the development of my country's hot-dip galvanizing industry, most enterprises have reconstructed the original old and small production lines. The zinc capacity of zinc pots generally exceeds 300 tons, and some zinc pots even exceed 1,000 tons. Lines with pot lengths over 12 meters are already q...
