Ladle baking machine: ladle baking machine, molten iron ladle baking machine, intermediate ladle

Steel (iron) ladle baking device type:

Applicable scope:

Used for on line (off line) baking of steel (iron) ladle and continuous casting tundish, including fast or slow baking of newly built ladle drying and turnover ladle, fast baking of online steel ladle (tundish), used for intermediate tank drying station, intermediate station preheating station, etc.

Performance characteristics:

The series of ladle baking devices produced by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. come in two forms: discrete and horizontal, consisting of three parts: mechanical structure, combustion system, and control system. The product design is reasonable, sturdy, and durable, with stable and reliable performance. Fast heating during baking, strong controllability of heating curve, easy operation, strong fuel adaptability, especially solving the problem of stable combustion of low calorific value fuels such as blast furnace gas.

Technical parameters:

Fuel usage: Zhongwei ZWKB series baking machines are suitable for different gas and liquid fuels, such as blast furnace gas, converter gas, producer gas, mixed gas, natural gas, liquefied petroleum gas, yellow phosphorus tail gas, calcium carbide furnace gas, mineral heat furnace gas, heavy oil, diesel, etc. According to the user's fuel supply situation, fuel parameters can be proposed by the user, and different forms of baking nozzles can be designed to ensure baking performance.

1. Blast furnace gas: calorific value 2900-3500KJ/Nm3, design pressure ≥ 2KPa

2. Converter gas: calorific value 6300KJ/Nm3, design pressure ≥ 2KPa

3. Coke oven gas: calorific value 16700KJ/Nm3, design pressure ≥ 1KPa

4. Producer gas: calorific value 5400KJ/Nm3, design pressure ≥ 1KPa

5. Mixed gas: calorific value 8300-13000KJ/Nm3, design pressure ≥ 1KPa

6. Liquefied petroleum gas: calorific value 42000KJ/Nm3, design pressure ≥ 1.0-1.5KPa

7. Diesel fuel: calorific value 37800KJ/kg, design pressure ≥ 1.0-1.5KPa

8. Heavy oil: calorific value 33500-37800KJ/kg, design pressure ≥ 1.5-2.0KPa

Offline steel (iron) ladle baking:

Fast or slow baking of newly built bags and turnover bags. When using blast furnace gas, the heating temperature is above 1100 ℃, and the temperature difference inside the ladle (tundish) is 20 ℃. Offline baking of cold packs for 2.5 hours, with a lining temperature of over 1000 ℃.

Online ladle baking:

For online steel ladle (tundish), use blast furnace gas for rapid baking, heating to above 1100 ℃, heating temperature ≥ 40 ℃/min, and temperature difference within the steel ladle (tundish) of 20 ℃. The online ladle (intermediate ladle) is baked for 20-30 minutes, and the temperature of the ladle lining reaches 1100 ℃.

Offline baking of intermediate tank:

The intermediate tank drying station is mainly used for new construction, cold repair, drying, and turnover. Online baking (fast) at room temperature -1100 ℃ for 1-1.5 hours; Offline baking (drying) at room temperature, -800 ℃, for 24-32 hours.

Online baking of intermediate tanks:

The intermediate tank preheating station is a specialized equipment for rapid baking of steel liquid containers, mainly used for preheating and baking of continuous casting intermediate tanks with online rapid heating. When using blast furnace gas, perform online baking at temperatures above 1100 ℃ for 60 minutes, with a heating rate of ≥ 40 ℃/min.
