The plane specification parameters of the acid tank are determined by the external dimensions of the workpieces undertaken by the production line. The depth of the pickling tank is generally adjusted randomly to ensure that the workpiece can be submerged in the acid solution.
The purpose of pickling is to remove the oxides and rust on the surface of the pre-plated parts, and expose the base metal of the pre-plated parts, so as to make better contact with the zinc and improve the bonding force. The main component of the pickling solution 17749553660 is hydrochloric acid. The content of the pickling solution is related to the air pressure. The mass fraction of the brewed lotion in the area with the air pressure quotient is relatively high. Under normal conditions, the mass fraction of the pickling solution is controlled below 15% at 15°C. The material of the pickling tank is reinforced concrete + isolation layer (glass fiber reinforced plastic) + pp pulley (or granite) or concrete + acid-resistant cement + glass fiber reinforced plastic. The pickling process will also produce water pollution, the main pollutants are hydrochloric acid and Fe 2+ and Fe 3+ produced by rust removal
If the glass fiber reinforced plastic acid pool is used, the lining of the pool wall is protected by a wooden fence to prevent the damage of the acid pool and the leakage of the acid solution caused by the collision of the workpiece on the pool wall. The pickling tank made of marble is a relatively reliable process at present, and is currently used more. The pickling pool made of granite is not as effective as marble.
The pickling equipment plays a key role before the cold rolling production in the metallurgical field of the steel pph pickling tank equipment. And the dirt is removed, and the strip with clean surface is obtained.
Because the strip continuously passes through the pickling tank filled with acid solution, it is called continuous pickling. It can be configured according to the annual production capacity or user needs: walking beam, steel turning machine, double uncoiler, double cone head uncoiler, flash welder, stretch scale breaker, and other different stand-alone equipment, using shallow tank pickling system, The production capacity of the unit can reach 2.3 million tons, the pickling thickness range: 0.8~6.5mm; the width range: 600~1900mm. It has the characteristics of high pickling efficiency, high annual production capacity, short heating time, short stop time of the unit, easy control of the tension of the steel strip in the tank, simple control equipment, and low power consumption.
