The furnace body is cylindrical and mounted on a horizontal axis frame. It can rotate and is also used for steelmaking. In the converter steelmaking process, making good slag is an important prerequisite for making good steel. Slag making is an important operation in converter steelmaking. The so-called slag making refers to the process operation of controlling the type and amount of slag entering the furnace so that the slag has certain properties to meet the needs of the steelmaking reaction in the molten pool. It is particularly important to do a good job in slag composition analysis and timely adjust the slag. Therefore, how to extract slag samples for analysis is an important operation in converter steelmaking.

[0003] The traditional slag taking device is that when the converter is tapping steel, a furnace worker stands at the side of the furnace mouth and extends a sampling rod into the furnace mouth to dip the slag.

When dipping the slag sample, the furnace worker needs to extend and drag the rod in the high temperature environment on the side of the furnace mouth. The labor intensity is high, and there is a certain risk factor when sampling. When the sampling rod is extended into the liquid surface of the molten pool, the converter slag is easy to splash, and there is often splashing caused by slag shells falling in the furnace. Even if the worker is on the side of the furnace mouth, there is a risk of large-scale burns. Utility Model Content
