Product Description:

With the rapid development of the steel industry, end users’ requirements on high steel quality are gradually increasing. Therefore, it has become an inevitable choice for steel enterprises to produce high-quality, high-tech and high value-added steel products.

Molten steel will directly affect both the quality and the performance of steel products and reducing slag carryover from converter into ladle during tapping is a key way to improve the steel quality. How to technically reduce the slag carryover during tapping has long been a technical problem unsolved in the steel industry and has become a barrier to develop special steel and quality steel in the converter way.

Advantages of converter tap hole sliding gate system compared with others:

1. Success rate: 100%.

2. Average slag thickness into ladle : ≤40mm.

3. Reduce re-sulfurization and re-phosphorization and improve steel quality.

4. Improve metal recycling rate.

5. Reduce the alloy consumption during secondary metallurgy.

6. Shortening ladle refining time and reduce synthetic slag consumption.

At present, the models for converter tap hole sliding gate system are as follows: ZZF-4ZH、YZL-3GY、ZZF-7J、ZZF-7F. This system has been successfully used in over 30 steel plants including Baosteel, Wusteel, Ansteel, Jing-Tang Steel, Meishan Steel and Nanjing Steel.
