Problems solved by technology

And because the traditional galvanized pot adopts the heating method of external heating, it will accelerate the corrosion of the pot body. Once the pot body is corroded, the zinc liquid in the pot body will leak into the furnace, which not only causes damage to the galvanized pot and zinc liquid loss, but also have a great impact on production
[0005] To sum up, the material structure and heating method of the existing galvanizing pots have many unsatisfactory features, such as short service life, high loss, poor zinc melting effect, and high zinc consumption.

Abstract

The invention relates to an internal-heating galvanized pot which comprises a pot body and a heating mechanism, wherein the pot body is composed of a pot body casing and a pot body inner core, and the pot body casing covers the external part of the pot body inner core; the heating mechanism is arranged on the inner wall of the pot body inner core and composed of a rectangular casing, a corrosion prevention layer, a radiant tube, a flue gas pipeline, a burner, a regulating valve and an exhaust pipeline; the corrosion prevention layer is arranged on the outer surface of the rectangular casing, and the radiant tube is arranged in the rectangular casing; a mounting plate is arranged on the pot body inner core, and the burner is mounted at the inlet of the rectangular casing; the gas inlet end of the burner is connected with the flue gas pipeline penetrating the mounting plate, and the regulating valve is mounted on the flue gas pipeline; the exhaust pipeline communicated with the outlet of the rectangular casing penetrates the mounting plate. The internal-heating galvanized pot has the advantages of long service life, low loss, good zinc melting effect, pollution reduction, high thermal efficiency, galvanization cost reduction and the like and is easy to realize.

Description

Technical field [0001] The invention relates to a hot-dip galvanizing equipment, in particular to an inner heating galvanizing pot. Background technique [0002] Hot-dip galvanizing is one of the most basic and effective anti-corrosion technologies for metal products, and is widely used in various fields of the national economy. In the hot-dip galvanizing process, the galvanizing pot is very expensive equipment. [0003] Once the pot leaks, the loss is serious, so the correct design of the galvanized pot is very important for the enterprise. The current galvanized pots are divided into two types, one is an iron galvanized pot, and the other is a ceramic galvanized pot. [0004] Iron galvanized pots are generally welded with 50-60mm thick low-carbon and low-silicon steel plates. Due to the different temperature requirements of the plated components (432℃-560℃), the life of the zinc pot ranges from several years to several Months or even ten to twenty days, and the slag production r...
