Description

Technical Field

[0001] This utility model relates to the field of iron and steel metallurgy technology, specifically to an immersion-type multi-functional steel ladle baking machine. Background Technology

[0002] The steel industry is a high-carbon industry, accounting for 15% of the nation's total emissions, second only to the power industry. my country's steel production ranks first in the world, accounting for as much as 54%. Steel ladle baking equipment is a crucial piece of equipment in steelmaking. Before use, steel ladles need to be baked to temperatures above 1000℃, typically using coal gas or natural gas. Carbon dioxide is generated during the baking process. Therefore, developing a baking equipment that shortens the baking time while still reaching the operating temperature can not only reduce carbon dioxide emissions but also save on fuel consumption, lower operating costs, and bring significant economic benefits.

[0003] Traditional baking ovens typically have burners mounted on the steel ladle lid. The flames emitted downwards from the burners preheat the steel ladle. If the flame length is short, a large amount of fuel and a long baking time are required to raise the bottom of the ladle to the required temperature. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an immersion-type multi-functional steel ladle oven, which solves the problem that traditional ovens typically place burners on the steel ladle lid and preheat the steel ladle by spraying flames downwards from the burners. However, if the flame length is short, a large amount of gas is required and the baking time is long enough to raise the bottom of the ladle to the required temperature.

[0006] (II) Technical Solution

[0007] This utility model provides the following technical solution: a gantry crane and a raw material package, wherein a mobile electric hoist is installed at the top horizontal rail of the gantry crane, a steel wire rope is connected to the output end of the mobile electric hoist, an immersion package cover is fixedly connected to the end of the steel wire rope away from the mobile electric hoist, a burner is installed at the bottom of the immersion package cover, and a flame detector, a thermocouple and an ignition device are fixedly connected to the outside of the burner;

[0008] The raw material package is wrapped around the bottom outside of the immersion cap. An air line and an oxygen line are connected through the top of the immersion cap. The end of the air line away from the immersion cap is fixedly connected to a gas metal hose. The end of the gas metal hose away from the air line is connected to a valve station.

[0009] Preferably, the immersion cover is connected to the valve station via an air line and a gas metal hose.

[0010] Preferably, the immersion cover is connected to the gantry crane via a mobile electric hoist and wire rope to form a lifting structure.

[0011] Preferably, the immersion cap and the raw material package form an overlapping structure.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an immersion-type multi-functional steel ladle baking oven, which has the following beneficial effects:

[0014] 1. This immersion-type multi-functional steel ladle baking oven can replace the original steel ladle baking oven. It can be configured as a heat storage type, oxygen-enriched type, pure oxygen type, or a combination of all three by controlling the air intake ratio of the air pipeline and oxygen pipeline through the valve station. The configuration can be selected according to the customer's choice.

[0015] 2. This immersion-type multi-functional steel bag baking oven uses a gantry crane and a mobile electric hoist to drive the lifting and rotation of the immersion bag lid, which solves the problem of traditional baking ovens using a winch drive, which can only flip up and down and cannot rotate left and right.

[0016] 3. This immersion-type multi-functional steel ladle oven has a combustion system that directly enters the interior of the steel ladle. A small-power burner can heat the bottom of the ladle, while the generated hot air rises along the sides to heat the inner refractory material. The immersion-type lid reduces the volume of the ladle, improves baking efficiency, saves gas consumption, and reduces carbon emissions. Attached Figure Description
